Set up important Lua paths, such as the directories in # which to install scripts and modules (shared libraries). # # Also detect Lua headers and libraries. The Lua version contained in the # header is checked to match the Lua interpreter version exactly. When # searching for Lua libraries, the version number is used as a suffix. # This is done with the goal of supporting multiple Lua installs (5.1, # 5.2, and 5.3 side-by-side). # # A note on compatibility with previous versions: This file has been # mostly rewritten for serial 18. Most developers should be able to use # these macros without needing to modify configure.ac. Care has been taken # to preserve each macro's behavior, but there are some differences: # # 1) AX_WITH_LUA is deprecated; it now expands to the exact same thing as # AX_PROG_LUA with no arguments. # # 2) AX_LUA_HEADERS now checks that the version number defined in lua.h # matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore # unnecessary, so it is deprecated and does not expand to anything. # # 3) The configure flag --with-lua-suffix no longer exists; the user # should instead specify the LUA precious variable on the command line. # See the AX_PROG_LUA description for details. # # Please read the macro descriptions below for more information. # # This file was inspired by Andrew Dalke's and James Henstridge's # python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4 # (serial 17). Basically, this file is a mash-up of those two files. I # like to think it combines the best of the two! # # AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua # paths. Adds precious variable LUA, which may contain the path of the Lua # interpreter. If LUA is blank, the user's path is searched for an # suitable interpreter. # # If MINIMUM-VERSION is supplied, then only Lua interpreters with a # version number greater or equal to MINIMUM-VERSION will be accepted. If # TOO-BIG-VERSION is also supplied, then only Lua interpreters with a # version number greater or equal to MINIMUM-VERSION and less than # TOO-BIG-VERSION will be accepted. # # The Lua version number, LUA_VERSION, is found from the interpreter, and # substituted. LUA_PLATFORM is also found, but not currently supported (no # standard representation). # # Finally, the macro finds four paths: # # luadir Directory to install Lua scripts. # pkgluadir $luadir/$PACKAGE # luaexecdir Directory to install Lua modules. # pkgluaexecdir $luaexecdir/$PACKAGE # # These paths are found based on $prefix, $exec_prefix, Lua's # package.path, and package.cpath. The first path of package.path # beginning with $prefix is selected as luadir. The first path of # package.cpath beginning with $exec_prefix is used as luaexecdir. This # should work on all reasonable Lua installations. If a path cannot be # determined, a default path is used. Of course, the user can override # these later when invoking make. # # luadir Default: $prefix/share/lua/$LUA_VERSION # luaexecdir Default: $exec_prefix/lib/lua/$LUA_VERSION # # These directories can be used by Automake as install destinations. The # variable name minus 'dir' needs to be used as a prefix to the # appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES. # # If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is # performed, otherwise ACTION-IF-NOT-FOUND is preformed. If ACTION-IF-NOT- # FOUND is blank, then it will default to printing an error. To prevent # the default behavior, give ':' as an action. # # AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be # expanded before this macro. Adds precious variable LUA_INCLUDE, which # may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If # LUA_INCLUDE is blank, then this macro will attempt to find suitable # flags. # # LUA_INCLUDE can be used by Automake to compile Lua modules or # executables with embedded interpreters. The *_CPPFLAGS variables should # be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE). # # This macro searches for the header lua.h (and others). The search is # performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE. # If the search is unsuccessful, then some common directories are tried. # If the headers are then found, then LUA_INCLUDE is set accordingly. # # The paths automatically searched are: # # * /usr/include/luaX.Y # * /usr/include/lua/X.Y # * /usr/include/luaXY # * /usr/local/include/luaX.Y # * /usr/local/include/lua-X.Y # * /usr/local/include/lua/X.Y # * /usr/local/include/luaXY # # (Where X.Y is the Lua version number, e.g. 5.1.) # # The Lua version number found in the headers is always checked to match # the Lua interpreter's version number. Lua headers with mismatched # version numbers are not accepted. # # If headers are found, then ACTION-IF-FOUND is performed, otherwise # ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then # it will default to printing an error. To prevent the default behavior, # set the action to ':'. # # AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be # expanded before this macro. Adds precious variable LUA_LIB, which may # contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank, # then this macro will attempt to find suitable flags. # # LUA_LIB can be used by Automake to link Lua modules or executables with # embedded interpreters. The *_LIBADD and *_LDADD variables should be used # for this purpose, e.g. mymod_LIBADD = $(LUA_LIB). # # This macro searches for the Lua library. More technically, it searches # for a library containing the function lua_load. The search is performed # with a combination of LIBS, LIBRARY_PATH, and LUA_LIB. # # If the search determines that some linker flags are missing, then those # flags will be added to LUA_LIB. # # If libraries are found, then ACTION-IF-FOUND is performed, otherwise # ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then # it will default to printing an error. To prevent the default behavior, # set the action to ':'. # # AX_LUA_READLINE: Search for readline headers and libraries. Requires the # AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from the # Autoconf Archive. # # If a readline compatible library is found, then ACTION-IF-FOUND is # performed, otherwise ACTION-IF-NOT-FOUND is performed. # # LICENSE # # Copyright (c) 2015 Reuben Thomas # Copyright (c) 2014 Tim Perkins # Copyright (c) Rubicon Rowe # # This program is free software: you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by the # Free Software Foundation, either version 3 of the License, or (at your # option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number.

END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Open the mount target with O_PATH to prevent open(2) failures with special files like FIFOs or UNIX sockets. - Fix sd-bus error handling for cpu quota and period props update. - container: use relative path for rootfs if possible. If the rootfs cannot be resolved and it is below the current working directory, only use its relative path. - wasmedge: access container environment variables for the WasmEdge configuration. - cgroup, systemd: use MemoryMax instead of MemoryLimit. Fixes a warning for using an old configuration name. - cgroup, systemd: improve checks for sd_bus_message_append errors * crun-1.15 - fix a mount point leak under /run/crun, add a retry mechanism to unmount the directory if the removal failed with EBUSY. - linux: cgroups: fix potential mount leak when /sys/fs/cgroup is already mounted, causing the posthooks to not run. - release: build s390x binaries using musl libc. - features: add support for potentiallyUnsafeConfigAnnotations. - handlers: add option to load wasi-nn plugin for wasmedge. - linux: fix "harden chdir()" security measure. The previous check was not correct. - crun: add option --keep to the run command. When specified the container is not automatically deleted when it exits. * crun-1.14.4 - linux: fix mount of file with recursive flags. Do not assume it is a directory, but check the source type. * crun-1.14.3 - follow up for 1.14.2. Drop the version check for each command. * crun-1.14.2 - crun: drop check for OCI version. A recent bump in the OCI runtime specs caused crun to fail with every config file. Just drop the check since it doesn't add any value. * crun-1.14.1 - there was recently a security vulnerability (CVE-2024-21626) in runc that allowed a malicious user to chdir(2) to a /proc/*/fd entry that is outside the container rootfs. While crun is not affected directly, harden chdir by validating that we are still inside the container rootfs. - container: attempt to close all the files before execv(2). if we leak any fd, it prevents execv to gain access to files outside the container rootfs through /proc/self/fd/$fd. - fix a regression caused by 1.14 when installing the ebpf filter on a kernel older than 5.11. - cgroup, systemd: fix segfault if the resources block is not specified. * crun-1.14 - build: drop dependency on libgcrypt. Use blake3 to compute the cache key. - cpuset: don't clobber parent cgroup value when writing the cpuset value. - linux: force umask(0). Iit ensures that the `mknodat` syscall is not affected by the umask of the calling process, allowing file permissions to be set as specified in the OCI configuration. - ebpf: do not require MEMLOCK for eBPF programs. This requirement was relaxed in Linux 5.11. * crun-1.13 - src: use O_CLOEXEC for all open/openat calls - cgroup v1: use "max" when pids limit < 0. - improve error message when idmap mount fails because the underlying file system has no support for it. - libcrun: fix compilation when building without libseccomp and libcap. - fix relative idmapped mount when using the custom annotation. * crun-1.12 - add new WebAssembly handler: spin. - systemd: fallback to system bus if session bus is not available. - configure the cpu rt and cpuset controllers before joining them to avoid running temporarily the workload on the wrong cpus. - preconfigure the cpuset with required resources instead of using the parent's set. This prevents needless churn in the kernel as it tracks which CPUs have load balancing disabled. - try attr//* before the attr/* files. Writes to the attr/* files may fail if apparmor is not the first "major" LSM in the list of loaded LSMs (e.g. lsm=apparmor,bpf vs lsm=bpf,apparmor). * crun-1.11.2 - fix a regression caused by 1.11.1 where the process crashes if there are no CPU limits configured on cgroup v1. - fix error code check for the ptsname_r function. * crun-1.11.1 - force a remount operation with bind mounts from the host to correctly set all the mount flags. * crun-1.11 - cgroup: honor cpu burst. - systemd: set CPUQuota and CPUPeriod on the scope cgroup. - linux: append tmpfs mode if missing for mounts. This is the same behavior of runc. - cgroup: always use the user session for rootless. * crun-1.10 - support for Intel Resource Director Technology (RDT). - new mount option "copy-symlink". When provided for a mount, if the source is a symlink, then it is copied in the container instead of attempting a mount. - linux: open mounts before setgroups if in a userns. This solves a problem where a directory that was previously accessible to the user, become inaccessible after setgroups causing the bind mount to fail. * crun-1.9.2 - cgroup: reset the inherited cpu affinity after moving to cgroup. Old kernels do that automatically, but new kernels remember the affinity that was set before the cgroup move, so we need to reset it in order to honor the cpuset configuration. * crun-1.9.1 - utils: ignore ENOTSUP when chmod a symlink. It fixes a problem on Linux 6.6 that always refuses chmod on a symlink. - build: fix build on CentOS 7 - linux: add new fallback when mount fails with EBUSY, so that there is not an additional tmpfs mount if not needed. - utils: improve error message when a directory cannot be created as a component of the path is already existing as a non directory. * crun-1.9 - linux: support arbitrary idmapped mounts. Now it is possible to specify a mapping for any type of mount, not only bind mounts. - linux: add support for "ridmap" mount option to support recursive idmapped mounts. - crun delete: call systemd's reset-failed. In case systemd cgroup driver is used, and the systemd unit has failed (e.g. oom-killed), systemd won't remove the unit (that is, unless the "CollectMode: inactive-or-failed" property is set). - linux: fix check for oom_score_adj. Write the oom_score_adj file even when the new value is 0. - features: Support mountExtensions. - linux: correctly handle unknown signal string when it doesn't start with a digit. - linux: do not attempt to join again already joined namespace. - wasmer: use latest wasix API. * crun-1.8.7 - linux: fix a race condition when an exec was performed immediately after the start and the setns with the procfd failed. - features: Fix annotations formatting. - linux: do not write some errors twice. - libcrun: handle SIGWINCH by resizing the terminal file descriptor. - crun: new command "crun features". - linux: fix handling of idmapped mounts when the container joins an existing PID namespace. - linux: support io_priority from the OCI specs. - linux: handle correctly the case where the status file is not written yet for a container. - crun: fix segfault for "ps" when the container is not using cgroups. - cgroup: allow setting swap to 0. * crun-1.8.6 - crun: new command "crun features". - linux: fix handling of idmapped mounts when the container joins an existing PID namespace. - linux: support io_priority from the OCI specs. - linux: handle correctly the case where the status file is not written yet for a container. - crun: fix segfault for "ps" when the container is not using cgroups. - cgroup: allow setting swap to 0. * crun-1.8.5 - scheduler: use definition from the OCI configuration file instead of the custom label that is now dropped and not supported anymore. - cgroup: fix creating cgroup under "domain threaded". - cgroup, systemd: set the memory limit on the system scope. - restore tty settings from the correct file descriptor. It was previously restoring the settings from the wrong file descriptor causing the tty settings to be changed on the calling terminal. - criu: check if the criu_join_ns_add function exists. Fix a segfault with new versions of CRIU. - linux: do not precreate devs with euid > 0. Fix creating devices when running the OCI runtime as non root user. - linux: improve PID detection on systems that lack pidfd. While there is still a window of time that the PID could be recycled, now it is now reduced to a minimum. - criu: fix memory leak. - logging: improve error message when dlopen fails. * crun-1.8.4 - fix build on CentOS 7. - drop custom annotation to set the time namespace and use the OCI specs instead. - cgroup: workaround cpu quota/period issue with v1. Sometimes setting CPU quota period fails when a new period is lower, and a parent cgroup has CPU quota limit set. - cgroup: fix set quota to -1 on cgroup v1. - criu: drop loading unused functions. * crun-1.8.3 - update: initialize the rt limits only on cgroup v1. * crun-1.8.2 - lua bindings for libcrun. - wasmedge: add current directory to preopen paths. - linux: inherit parent mount flags when making a path masked. - libcrun: custom annotation to set the scheduler for the container process. - cgroup: fallback to blkio.bfq files if blkio is not available on cgroup v1. - cgroup: initialize rt limits when using systemd. - tty: chown the tty to the exec user instead of the user specified to create the container. - cgroup: fallback to create cgroupfs as sibling of the current cgroup if there is none specified and it cannot be created in the root cgroup. * crun-1.8.1 - linux: idmapped mounts expect the same configuration as the user namespace mappings. Before they were expecting the inverted mapping. It is a breaking change, but the behavior was aligned to what runc will do as well. - krun: always allow /dev/kvm in the cgroup configuration. - handlers: disable exec for handlers that do not support it. - selinux: allow setting fscontext using a custom annotation. - cgroup: reset systemd unit if start fails. - cgroup: rmdir the entire systemd scope. It fixes a leak on cgroupv1. - cgroup: always delete the cgroup on errors. On some errors it could have been leaked before. * crun-1.8 - linux: precreate devices on the host. - cgroup: support cpuset mounted with noprefix. - linux: mount the source cgroup if cgroupns=host. - libcrun: don't clone self from read-only mount. - build: fix build without dlfcn.h. - linux: set PR_SET_DUMPABLE. - utils: fix applying AppArmor profile. - linux: write setgroups=deny when mapping a single uid/gid. - cgroup: fix enter cgroupv1 mount on RHEL 7. * crun-1.7.2 - criu: hardcode library name to libcriu.so.2. - cgroup: always enable all controllers, even if the cgroup was already joined. Regression caused by crun-1.7. * crun-1.7.1 - criu: load libcriu dynamically. - seccomp: initialize libgcrypt. - handlers: fix rewriting the argv if the full cmdline doesn't fit. - utils: honor SELinux label when using a custom handler. - utils: honor AppArmor label when using a custom handler. - krun: copy the OCI configuration file into the container. - utils: fix creating the default user namespace when running with euid != 0. - Add setlinebuf() when --debug and --log=file: are used. - Fix timestamp format in the error messages. - krun: disable libkrun's collection of env vars * crun-1.7 - seccomp: use a cache for the generated BPF. - add support for setting the domainname through the OCI spec. - handlers: define wasm and krun. - wasmtime: add support for compiling .wat format. - cgroup: honor checkBeforeUpdate on cgroupv2. - crun: chown std streams before joining the user namespace. - crun: display rundir in --version output. - container: with cgroupfs use clone3 to join directly the target cgroup. - linux: create parent directories for created devices with mode 0755. - wasm: inherit environment variables in the WasmEdge handler. * crun-1.6 - runc compatibility: -v now prints the version string. - build: fix build with glibc 2.36. - container: drop intermediate userns custom feature. - cgroup: change the delegate cgroup semantic so that the cgroup is created in the container payload after the cgroup namespace is created. - seccomp: use helper process to send file descriptor to the listener socket. It enables to be notified on every syscall without hanging the main process. - linux: add a fallback to using kill(2) if pidfd_send_signal(2) fails with ENOSYS. - krun: add support for krun-sev. - wasmtime: always grant file system capability for workdir inside the container. - wasmtime: inherit arguments list from the handler instead of the current process. - wasmedge: use released wasmedge library instead of libwasmedge_c.so. * crun-1.5 - add mono based native .NET handler - new Wasmtime backend for running WebAssembly - add support for wasmedge 0.10 and dropping support for wasmedge 0.9.x - dropping support for experimental `WasmEdgeProcess` from wasmedge handler - honor process user's uid when setting the HOME environment variable - create the current working directory if it is missing in the container - fallback to using a tmpfs mount if umount of /sys and /proc fails - fallback to netlink to setup lo device - fix creating devices in the rootfs - fallback to using io.weight if io.bfq.weight doesn't exist - remove tun/tap from the default allow list - linux: devices mounts have noexec and nosuid - fix copyup of files from the container to the tmpfs - honor $PATH for newgidmap and newguidmap - krun: limit the number of vCPUs to 8 - cgroup: add support for cpu.idle * crun-1.4.5 - CRIU: add support for different manage cgroups modes. - linux: the hook processes inherit the crun process environment if there is no environment block specified in the OCI configuration. - exec: fix double free when using --apparmor and --process-label. * crun-1.4.4 - wasm, kubernetes: support wasm for kubernetes infrastructure with side-cars - Resolve symlinks in bind mounts when creating a user namespace. - Fix CVE-2022-27650: exec does not set inheritable capabilities. * crun-1.4.3 - cgroup: avoid infinite loop when deleting a cgroup if it contains processes that cannot be terminated. - support additional options for idmap mounts. It is now possible to specify what mappings must be used for the idmapped mount. - open the source for a bind mount in the host. It is useful when creating a user namespace so that the parent directories for the source directory are not required to be accessible to the users in the user namespace. * crun-1.4.2 - CRIU: add pre-dump support. - Fix running with a read-only /dev. The /dev/console file is created before re-mounting /dev as read-only. - Ignore EROFS when chowning standard stream files. - Add validation for sysctls before applying them. - Attempt looking up the executable after the setresuid syscall, this solves an issue on NFS when the executable file is not owned by root in the container, but the UID:GID combination configured for the container can access it. * crun-1.4.1 - Fix check for an invalid path. crun was performing the wrong check to validate a path, causing spurious failures at runtime. - Allow deleting a container while in `created` state. It goes against what the OCI runtime specs dictate, but it is the expected behavior since runc allows it. - Fix regression when joining a container that has explicit paths for the namespaces. - cgroup: do not set cpu limits if number of shares is set to 0. Moby uses 0 to indicate no limits. - Fix build issues when configured with --enable-shared. - Fix build on systems where OPEN_TREE_CLOEXEC is not defined. - Improve diagnostics for errors returned by dbus. * crun-1.4 - wasm: support for running on kubernetes with containerd. - linux: add support for recursive mount options. e.g. it is possible to specify "rro" to make the mount read-only recursively. - add support for idmapped mounts through a new mount option "idmap". - linux: improve detection of /dev target. Previously a mount like `/dev/` was not properly detected as mounting /dev/ from the host. - now crun exec uses CLONE_INTO_CGROUP on supported kernels when using cgroup v2. - retry the openat2 syscall if it fails with EAGAIN. - cgroup: set the CPUWeight/CPUShares on the systemd scope cgroup. - on new kernels, use setns with pidfd. - attempt the chdir again with the specified user if it failed before changing credentials. - ebpf: fix build on 32 bits systems. - crun --version shows the configured handlers. * crun-1.3 - add support to natively build and run WebAssembly workload and WebAssembly containers. - allow to specify sub-cgroup for exec. - chown std streams if they are not a TTY. - attach the correct streams if the container is suspended and restored multiple times. - fix race condition when enabling controllers on cgroup v2. - the fallback code to mount cgroupfs bind mounts the current cgroup path instead of the host /sys. * crun-1.2 - exec: fix regression in 1.1 where containers are being wrongly reported as paused. - criu: add support for external ipc, uts and time namespaces. * crun-1.1 - cgroup: use cgroup.kill when available. It is faster to kill a container through its cgroup as there is no need to recurse over the cgroup pids and terminate each one of them. - exec: refuse to exec in a paused container/cgroup. - container: Set primary process to 1 via LISTEN_PID by default if user configuration is missing. - criu: Add support for external PID namespace. - criu: fix save of external descriptors.

If the openat2 syscall is interrupted, try again. * crun-1.0 - cgroup: chown the current container cgroup to root in the container. - linux: treat pidfd_open failures EINVAL as ESRCH - cgroup: add support for setting memory.use_hierarchy on cgroup v1. - Makefile.am: fix link error when using directly libcrun. - Fix symlink target mangling for tmpcopyup targets. * crun-0.21 - honor memory swappiness set to 0 - status: add fields for owner and created timestamp - cgroup: lookup pids controller as well when the memory controller is not available - when compiled with krun, automatically use it if the current executable file is called "krun". * crun-0.20.1 - container: ignore error when resetting the SELinux label for the keyring. * crun-0.20 - container: call prestart hooks before rootfs is RO. - cgroup: added support cleaning custom controllers on cgroupv1. - spec: add support for --bundle. - exec: add --no-new-privs. - exec: add --process-label and --apparmor to change SELinux and AppArmor labels. - cgroup: kill procs in cgroup on EBUSY. - cgroup: ignore devices errors when running in a user namespace. - seccomp: drop SECCOMP_FILTER_FLAG_LOG by default. - seccomp: report correct action in error message. - apply SELinux label to keyring. - add custom annotation run.oci.delegate-cgroup. - close_range fallbacks to close on EPERM. - report error if the cgroup path was set and the cgroup could not be joined. * crun-0.19.1 - on exec, honor additional_gids from the process spec, not the container definition. - spec: add cgroup ns if on cgroup v2. - systemd: support array of strings for cgroup annotation. * crun-0.19 - join all the cgroup v1 controllers. - raise a warning when newuidmap/newgidmap fail. - handle eBPF access(dev_name, F_OK) call correctly. - fix some memory leaks on errors when libcrun is used by a long running process. - fix the SELinux label for masked directories. - support default seccomp errno value. - fail if no default seccomp action specified. - support OCI seccomp notify listener. - improve OOM error messages. - ignore unknown capabilities and raise a warning. - always remount bind mounts to drop not requested mount flags. * crun-0.18 - fix build without CLONE_NEWCGROUP. - fix conversion from blkio to io. - add custom annotation to load raw BPF. - set working directory for libkrun - fix symlink lookup on old kernels that lack openat2 - skip +cpu on EINVAL in cgroup root. Enabling the cpu controller is not permitted if there are already realtime processes running on the system. - Fix permission error when using NOTIFY_SOCKET with username spaces. - set HOME to root if the user not found. - simplify mount logic to not use a temporary mount. - ignore ENOSYS from keyctl. * crun-0.17 - allow creating user namespaces without root being mapped. - allow arbitrary IDs with single ID userns. - use close_range(CLOSE_RANGE_CLOEXEC) where available. - honor /sys/kernel/cgroup/delegate. - fix an issue with hooks running in the container PID namespace. - fix building without seccomp. - fix building without libcap. * crun-0.16 - CRIU support. - fallback to openat if openat2 returns EPERM. - ignore ENOENT for cgroup v1 mounts, if the mount fails with ENOENT, the controller might have been unmounted. - fix another race reading cgroup freeze. Reading from the cgroup fails with ENODEV if the cgroup was deleted in the meanwhile. * crun-0.15.1 - add experimental support for libkrun. - fix check for pidfd availability on older kernels. - linux: do not set data when remounting read-only. Fix 'ro' mounts on older kernels when SELinux is enabled. - linux: label the cgroup v1 tmpfs when SELinux is enabled. - container: truncate the pid file before writing to it. - exec: fix check for read bytes from the sync socket. - check the process has a cgroup before allowing pause and resume. - linux: always create a user namespace if not running with euid == 0. - libcrun can use a hook instead of executing a container process. - use libyajl to generate hooks json input. - handle correctly ENOENT for seccomp notifications. * crun-0.15 - add support for OCI unified cgroup v2. - add json format option to `crun list`. - get last kernel capability dynamically instead of using a build time constant. - enable all available cgroup controllers. - support the seccomp SCMP_ACT_LOG action. - support the seccomp SCMP_ACT_KILL_THREAD action. - properly set a SELinux label for the mqueue mount. - `crun kill` uses pidfd when supported. - experimental support for seccomp notifications. - fix bundle option for `crun create` and `crun run`. - allow to declare path to config file. - check /sys/kernel/security/apparmor when using AppArmor. - doesn't accept type=bind alone anymore, but require either "bind" or "rbind" to be present in the mount flags. * crun-0.14.1 - fix a regression in crun-0.14 where openat2(2) would fail when bind mounting a symlink. - various small fixes to allow running regression tests outside of source tree. * crun-0.14 - cgroup, systemd: create container under subcgroup. Now a "/container" sub-cgroup is created and fully managed by libcrun. This is a different behaviour than what runc does. - libcrun: use the openat2 syscall available since Linux 5.6. - container: allow hooks output to file through an annotation. - linux: support joining PID/IPC namespace not owned by the user namespace.

Older linux versions complain when the selinux label is specified on a remount. - utils: fix mount on not writeable path. - cgroup: support systemd properties via annotations. - systemd: do not set hard-code collectmode value. It can be set through an annotation. - cgroup: write the correct blkio settings. - exec: do not inherit env variables from main pid. - ebpf: fix endianness issue on s390x. - linux: fix recursive mount on cgroup v1. * crun-0.12.2.1 - when not using a cgroup namespace, mount only the cgroup v1 subpath. * crun-0.12.2 - do not require read permissions on / - add support for the "time" namespace via a custom annotation - fix mount of cgroup v1 when using a cgroup namespace - set default umask to 0022 - use the correct path for notify socket with "crun run -d" - always use setsid - use correct indices for seccomp generation - fixed several issues with cgroup v2 and the cgroupfs driver * crun-0.12.1 - fix the order of clone syscall arguments on s390 and cris. - if no mode is specified use 0666 for devices. - fix running with a relative bundle directory. - fix some regressions in the mounts path resolution. - drop a warning when cgroup are not available for rootless. * crun-0.12 - masked paths use only MS_UNBINDABLE - mount doesn't specify mount data when there are no options - support new hook types: createRuntime, createContainer and startContainer - safer mount options. A temporary mount is prepared outside of the rootfs before being moved to it. - apply selinux/apparmor before the pivot_root. - handle correctly proc remounts. It is now supported to specify hidepid= - fix exec if a namespace is not available. - handle swap limit with the same semantic as on cgroup v1. - bring network device up. - reset all signal handlers to default. * crun-0.11 - cgroups2: map memory reservation to memory.low - statx fallbacks to stat on EINVAL - utils: do not fail if the path we are trying to create already exists - generate seccomp profile in the parent process, not in the container init process.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

[![Coverity Status](https://scan.coverity.com/projects/17787/badge.svg)](https://scan.coverity.com/projects/giuseppe-crun) [![CodeQL](https://github.com/containers/crun/workflows/CodeQL/badge.svg)](https://github.com/containers/crun/actions?query=workflow%3ACodeQL) A fast and low-memory footprint OCI Container Runtime fully written in C. crun conforms to the OCI Container Runtime specifications (). ## Documentation The user documentation is available [here](crun.1.md). ## Why another implementation? While most of the tools used in the Linux containers ecosystem are written in Go, I believe C is a better fit for a lower level tool like a container runtime. runc, the most used implementation of the OCI runtime specs written in Go, re-execs itself and use a module written in C for setting up the environment before the container process starts. crun aims to be also usable as a library that can be easily included in programs without requiring an external process for managing OCI containers. ## Performance crun is faster than runc and has a much lower memory footprint. This is the elapsed time on my machine for running sequentially 100 containers, the containers run `/bin/true`: | | crun | runc | % | | ------------- | ------: | -----: | ------: | | 100 /bin/true | 0:01.69 | 0:3.34 | \-49.4% | crun requires fewer resources, so it is also possible to set stricter limits on the memory allowed in the container: ```console # podman --runtime /usr/bin/runc run --rm --memory 4M fedora echo it works Error: container_linux.go:346: starting container process caused "process_linux.go:327: getting pipe fds for pid 13859 caused \"readlink /proc/13859/fd/0: no such file or directory\"": OCI runtime command not found error # podman --runtime /usr/bin/crun run --rm --memory 512k fedora echo it works it works ``` ## Dependencies These dependencies are required for the build: ### Fedora ```console $ sudo dnf install -y make python git gcc automake autoconf libcap-devel \ systemd-devel yajl-devel libseccomp-devel pkg-config \ go-md2man glibc-static python3-libmount libtool ``` ### RHEL/CentOS 8 ```console $ sudo yum --enablerepo='*' --disablerepo='media-*' install -y make automake \ autoconf gettext \ libtool gcc libcap-devel systemd-devel yajl-devel \ glibc-static libseccomp-devel python36 git ``` go-md2man is not available on RHEL/CentOS 8, so if you'd like to build the man page, you also need to manually install go-md2man. It can be installed with: ```console $ sudo yum --enablerepo='*' install -y golang $ export GOPATH=$HOME/go $ go get github.com/cpuguy83/go-md2man $ export PATH=$PATH:$GOPATH/bin ``` ### Ubuntu ```console $ sudo apt-get install -y make git gcc build-essential pkgconf libtool \ libsystemd-dev libprotobuf-c-dev libcap-dev libseccomp-dev libyajl-dev \ go-md2man autoconf python3 automake ``` ### Alpine ```console # apk add gcc automake autoconf libtool gettext pkgconf git make musl-dev \ python3 libcap-dev libseccomp-dev yajl-dev argp-standalone go-md2man ``` ### Tumbleweed ```console # zypper install make automake autoconf gettext libtool gcc libcap-devel \ systemd-devel libyajl-devel libseccomp-devel python3 go-md2man \ glibc-static; ``` Note that Tumbleweed requires you to specify libseccomp's header file location as a compiler flag. ```console # ./autogen.sh # ./configure CFLAGS='-I/usr/include/libseccomp' # make ``` ## Build Unless you are also building the Python bindings, Python is needed only by libocispec to generate the C parser at build time, it won't be used afterwards. Once all the dependencies are installed: ```console $ ./autogen.sh $ ./configure $ make ``` To install into default PREFIX (`/usr/local`): ```console $ sudo make install ``` ### Shared Libraries The previous build instructions do not enable shared libraries, therefore you will be unable to use libcrun. If you wish to build the shared libraries you can change the previous `./configure` statement to `./configure --enable-shared`. ## Static build It is possible to build a statically linked binary of crun by using the officially provided [nix](https://nixos.org/nixos/packages.html?attr=crun&channel=unstable&query=crun) package and the derivation of it [within this repository](nix/). The builds are completely reproducible and will create a x86\_64/amd64 stripped ELF binary for [glibc](https://www.gnu.org/software/libc). ### Nix To build the binaries by locally installing the nix package manager: ```console $ curl -L https://nixos.org/nix/install | sh $ git clone --recursive https://github.com/containers/crun.git && cd crun $ nix build -f nix/ $ ./result/bin/crun --version ``` ### Ansible An [Ansible Role](https://github.com/alvistack/ansible-role-crun) is also available to automate the installation of the above statically linked binary on its supported OS: ```console $ sudo su - # mkdir -p ~/.ansible/roles # cd ~/.ansible/roles # git clone https://github.com/alvistack/ansible-role-crun.git crun # cd ~/.ansible/roles/crun # pip3 install --upgrade --ignore-installed --requirement requirements.txt # molecule converge # molecule verify ``` ## Lua bindings A Lua binding is available.

The runtime detaches from the container process once the container environment is created. It is necessary to successively use `start` for starting the container. **delete** Remove definition for a container. **exec** Exec a command in a running container. **list** List known containers. **kill** Send the specified signal to the container init process. If no signal is specified, SIGTERM is used. **ps** Show the processes running in a container. **run** Create and immediately start a container. **spec** Generate a configuration file. **start** Start a container that was previously created. A container cannot be started multiple times. **state** Output the state of a container. **pause** Pause all the processes in the container. **resume** Resume the processes in the container. **update** Update container resource constraints. **checkpoint** Checkpoint a running container using CRIU **restore** Restore a container from a checkpoint # STATE By default, when running as root user, crun saves its state under the **/run/crun** directory. As unprivileged user, instead the *XDG_RUNTIME_DIR* environment variable is honored, and the directory **$XDG_RUNTIME_DIR/crun** is used. The global option **--root** overrides this setting. # GLOBAL OPTIONS **--debug** Produce verbose output. **--log**=_LOG-DESTINATION_ Define the destination for the error and warning messages generated by crun. If the error happens late in the container init process, when crun already stopped watching it, then it will be printed to the container stderr. It is specified in the form *BACKEND:SPECIFIER*. These following backends are supported: - file:PATH - journald:IDENTIFIER - syslog:IDENTIFIER If no backend is specified, then *file:* is used by default. **--log-format**=_FORMAT_ Define the format of the log messages. It can either be **text**, or **json**. The default is **text**. **--no-pivot** Use `chroot(2)` instead of `pivot_root(2)` when creating the container. This option is not safe, and should be avoided. **--root**=_DIR_ Defines where to store the state for crun containers. **--systemd-cgroup** Use systemd for configuring cgroups. If not specified, the cgroup is created directly using the cgroupfs backend. **--cgroup-manager**=_MANAGER_ Specify what cgroup manager must be used. Permitted values are **cgroupfs**, **systemd** and **disabled**. **-?**, **--help** Print a help list. **--usage** Print a short usage message. **-V**, **--version** Print program version ## CREATE OPTIONS crun [global options] create [options] CONTAINER **--bundle**=_PATH_ Path to the OCI bundle, by default it is the current directory. **--config**=_FILE_ Override the configuration file to use.

The default value is **config.json**. **--console-socket**=_SOCKET_ Path to a UNIX socket that will receive the ptmx end of the tty for the container. **--no-new-keyring** Keep the same session key. **--preserve-fds**=_N_ Additional number of FDs to pass into the container. **--pid-file**=_PATH_ Path to the file that will contain the container process PID. **--detach** Detach the container process from the current session. ## DELETE OPTIONS crun [global options] delete [options] CONTAINER **--force** Delete the container even if it is still running. **--regex**=_REGEX_ Delete all the containers that satisfy the specified regex. ## EXEC OPTIONS crun [global options] exec [options] CONTAINER CMD **--apparmor**=_PROFILE_ Set the apparmor profile for the process. **--console-socket**=_SOCKET_ Path to a UNIX socket that will receive the ptmx end of the tty for the container. **--cwd**=_PATH_ Set the working directory for the process to PATH. **--cap**=_CAP_ Specify an additional capability to add to the process. **--detach** Detach the container process from the current session. **--cgroup**=_PATH_ Specify a sub-cgroup path inside the container cgroup. The path must already exist in the container cgroup. **--env**=_ENV_ Specify an environment variable. **--no-new-privs** Set the no new privileges value for the process. **--preserve-fds**=_N_ Additional number of FDs to pass into the container. **--process**=_FILE_ Path to a file containing the process JSON configuration. **--process-label**=_VALUE_ Set the asm process label for the process commonly used with selinux. **--pid-file**=_PATH_ Path to the file that will contain the new process PID. **-t** **--tty** Allocate a pseudo TTY. **-u _USERSPEC_ **--user**=_USERSPEC_ Specify the user in the form UID[:GID]. ## LIST OPTIONS crun [global options] list [options] **-q** **--quiet** Show only the container ID. ## KILL OPTIONS crun [global options] kill [options] CONTAINER SIGNAL **--all** Kill all the processes in the container. **--regex**=_REGEX_ Kill all the containers that satisfy the specified regex. ## PS OPTIONS crun [global options] ps [options] **--format**=_FORMAT_ Specify the output format. It must be either `table` or `json`. By default `table` is used. ## SPEC OPTIONS crun [global options] spec [options] **-b** _DIR_ **--bundle**=_DIR_ Path to the root of the bundle dir (default "."). **--rootless** Generate a config.json file that is usable by an unprivileged user. ## UPDATE OPTIONS crun [global options] update [options] CONTAINER **--blkio-weight**=_VALUE_ Specifies per cgroup weight. **--cpu-period**=_VALUE_ CPU CFS period to be used for hardcapping. **--cpu-quota**=_VALUE_ CPU CFS hardcap limit. **--cpu-rt-period**=_VALUE_ CPU realtime period to be used for hardcapping. **--cpu-rt-runtime**=_VALUE_ CPU realtime hardcap limit. **--cpu-share**=_VALUE_ CPU shares. **--cpuset-cpus**=_VALUE_ CPU(s) to use. **--cpuset-mems**=_VALUE_ Memory node(s) to use. **--kernel-memory**=_VALUE_ Kernel memory limit. **--kernel-memory-tcp**=_VALUE_ Kernel memory limit for TCP buffer. **--memory**=_VALUE_ Memory limit. **--memory-reservation**=_VALUE_ Memory reservation or soft_limit. **--memory-swap**=_VALUE_ Total memory usage. **--pids-limit**=_VALUE_ Maximum number of pids allowed in the container. **-r**, **--resources**=_FILE_ Path to the file containing the resources to update. ## CHECKPOINT OPTIONS crun [global options] checkpoint [options] CONTAINER **--image-path**=_DIR_ Path for saving CRIU image files **--work-path**=_DIR_ Path for saving work files and logs **--leave-running** Leave the process running after checkpointing **--tcp-established** Allow open TCP connections **--ext-unix-sk** Allow external UNIX sockets **--shell-job** Allow shell jobs **--pre-dump** Only checkpoint the container's memory without stopping the container. It is not possible to restore a container from a pre-dump. A pre-dump always needs a final checkpoint (without **--pre-dump**). It is possible to make as many pre-dumps as necessary. For a second pre-dump or for a final checkpoint it is necessary to use **--parent-path** to point crun (and thus CRIU) to the pre-dump. **--parent-path**=_DIR_ Doing multiple pre-dumps or the final checkpoint after one or multiple pre-dumps requires that crun (and thus CRIU) knows the location of the pre-dump. It is important to use a relative path from the actual checkpoint directory specified via **--image-path**. It will fail if an absolute path is used. **--manage-cgroups-mode**=_MODE_ Specify which CRIU manage cgroup mode should be used. Permitted values are **soft**, **ignore**, **full** or **strict**. Default is **soft**. ## RESTORE OPTIONS crun [global options] restore [options] CONTAINER **-b DIR** **--bundle**=_DIR_ Container bundle directory (default ".") **--image-path**=_DIR_ Path for saving CRIU image files **--work-path**=_DIR_ Path for saving work files and logs **--tcp-established** Allow open TCP connections **--ext-unix** Allow external UNIX sockets **--shell-job** Allow shell jobs **--detach** Detach from the container's process **--pid-file**=_FILE_ Where to write the PID of the container **--manage-cgroups-mode**=_MODE_ Specify which CRIU manage cgroup mode should be used. Permitted values are **soft**, **ignore**, **full** or **strict**. Default is **soft**. # Extensions to OCI ## `run.oci.mount_context_type=context` Set the mount context type on volumes mounted with SELinux labels. Valid context types are: context (default) fscontext defcontext rootcontext More information on how the context mount flags works see the `mount(8)` man page. ## `run.oci.seccomp.receiver=PATH` If the annotation `run.oci.seccomp.receiver=PATH` is specified, the seccomp listener is sent to the UNIX socket listening on the specified path. It can also set with the `RUN_OCI_SECCOMP_RECEIVER` environment variable. It is an experimental feature, and the annotation will be removed once it is supported in the OCI runtime specs. It must be an absolute path. ## `run.oci.seccomp.plugins=PATH` If the annotation `run.oci.seccomp.plugins=PLUGIN1[:PLUGIN2]...` is specified, the seccomp listener fd is handled through the specified plugins. The plugin must either be an absolute path or a file name that is looked up by `dlopen(3)`. More information on how the lookup is performed are available on the `ld.so(8)` man page. ## `run.oci.seccomp_fail_unknown_syscall=1` If the annotation `run.oci.seccomp_fail_unknown_syscall` is present, then crun will fail when an unknown syscall is encountered in the seccomp configuration. ## `run.oci.seccomp_bpf_data=PATH` If the annotation `run.oci.seccomp_bpf_data` is present, then crun ignores the seccomp section in the OCI configuration file and use the specified data as the raw data to the `seccomp(SECCOMP_SET_MODE_FILTER)` syscall. The data must be encoded in base64. It is an experimental feature, and the annotation will be removed once it is supported in the OCI runtime specs. ## `run.oci.keep_original_groups=1` If the annotation `run.oci.keep_original_groups` is present, then crun will skip the `setgroups` syscall that is used to either set the additional groups specified in the OCI configuration, or to reset the list of additional groups if none is specified. ## `run.oci.pidfd_receiver=PATH` It is an experimental feature and will be removed once the feature is in the OCI runtime specs. If present, specify the path to the UNIX socket that will receive the pidfd for the container process. ## `run.oci.systemd.force_cgroup_v1=/PATH` If the annotation `run.oci.systemd.force_cgroup_v1=/PATH` is present, then crun will override the specified mount point `/PATH` with a cgroup v1 mount made of a single hierarchy `none,name=systemd`. It is useful to run on a cgroup v2 system containers using older versions of systemd that lack support for cgroup v2. **Note**: Your container host has to have the cgroup v1 mount already present, otherwise this will not work. If you want to run the container rootless, the user it runs under has to have permissions to this mountpoint. For example, as root: ``` mkdir /sys/fs/cgroup/systemd mount cgroup -t cgroup /sys/fs/cgroup/systemd -o none,name=systemd,xattr chown -R the_user.the_user /sys/fs/cgroup/systemd ``` ## `run.oci.systemd.subgroup=SUBGROUP` Override the name for the systemd sub cgroup created under the systemd scope, so the final cgroup will be like: ``` /sys/fs/cgroup/$PATH/$SUBGROUP ``` When it is set to the empty string, a sub cgroup is not created. If not specified, it defaults to `container` on cgroup v2, and to `""` on cgroup v1. e.g. ``` /sys/fs/cgroup//system.slice/foo-352700.scope/container ``` ## `run.oci.delegate-cgroup=DELEGATED-CGROUP` If the `run.oci.systemd.subgroup` annotation is specified, yet another sub-cgroup is created and the container process is moved here. If a cgroup namespace is used, the cgroup namespace is created before moving the container to the delegated cgroup. ``` /sys/fs/cgroup/$PATH/$SUBGROUP/$DELEGATED-CGROUP ``` The runtime doesn't apply any limit to the `$DELEGATED-CGROUP` sub-cgroup, the runtime uses only `$PATH/$SUBGROUP`. The container payload fully manages `$DELEGATE-CGROUP`, the limits applied to `$PATH/$SUBGROUP` still applies to `$DELEGATE-CGROUP`. Since cgroup delegation is not safe on cgroup v1, this option is supported only on cgroup v2. ## `run.oci.hooks.stdout=FILE` If the annotation `run.oci.hooks.stdout` is present, then crun will open the specified file and use it as the stdout for the hook processes. The file is opened in append mode and it is created if it doesn't already exist. ## `run.oci.hooks.stderr=FILE` If the annotation `run.oci.hooks.stderr` is present, then crun will open the specified file and use it as the stderr for the hook processes. The file is opened in append mode and it is created if it doesn't already exist. ## `run.oci.handler=HANDLER` It is an experimental feature. If specified, run the specified handler for execing the container. The only supported values are `krun` and `wasm`. - `krun`: When `krun` is specified, the `libkrun.so` shared object is loaded and it is used to launch the container using libkrun. - `wasm`: If specified, run the wasm handler for container. Allows running wasm workload natively. Accepts a `.wasm` binary as input and if `.wat` is provided it will be automatically compiled into a wasm module. Stdout of wasm module is relayed back via crun. ## tmpcopyup mount options If the `tmpcopyup` option is specified for a tmpfs, then the path that is shadowed by the tmpfs mount is recursively copied up to the tmpfs itself. ## copy-symlink mount options If the `copy-symlink` option is specified, if the source of a bind mount is a symlink, the symlink is recreated at the specified destination instead of attempting a mount that would resolve the symlink itself. If the destination already exists and it is not a symlink with the expected content, crun will return an error. ## r$FLAG mount options If a `r$FLAG` mount option is specified then the flag `$FLAG` is set recursively for each children mount. These flags are supported: - "rro" - "rrw" - "rsuid" - "rnosuid" - "rdev" - "rnodev" - "rexec" - "rnoexec" - "rsync" - "rasync" - "rdirsync" - "rmand" - "rnomand" - "ratime" - "rnoatime" - "rdiratime" - "rnodiratime" - "rrelatime" - "rnorelatime" - "rstrictatime" - "rnostrictatime" ## idmap mount options If the `idmap` option is specified then the mount is ID mapped using the container target user namespace. This is an experimental feature and can change at any time without notice. The `idmap` option supports a custom mapping that can be different than the user namespace used by the container. The mapping can be specified after the `idmap` option like: `idmap=uids=0-1-10#10-11-10;gids=0-100-10`. For each triplet, the first value is the start of the backing file system IDs that are mapped to the second value on the host. The length of this mapping is given in the third value. Multiple ranges are separated with `#`. These values are written to the `/proc/$PID/uid_map` and `/proc/$PID/gid_map` files to create the user namespace for the idmapped mount. The only two options that are currently supported after `idmap` are `uids` and `gids`. When a custom mapping is specified, a new user namespace is created for the idmapped mount. If no option is specified, then the container user namespace is used. If the specified mapping is prepended with a '@' then the mapping is considered relative to the container user namespace. The host ID for the mapping is changed to account for the relative position of the container user in the container user namespace. For example, the mapping: `uids=@1-3-10`, given a configuration like ``` "uidMappings": [ { "containerID": 0, "hostID": 0, "size": 1 }, { "containerID": 1, "hostID": 2, "size": 1000 } ] ``` will be converted to the absolute value `uids=1-4-10`, where 4 is calculated by adding 3 (container ID in the `uids=` mapping) and 1 (`hostID - containerID` for the user namespace mapping where `containerID = 1` is found). The current implementation doesn't take into account multiple user namespace ranges, so it is the caller's responsibility to split a mapping if it overlaps multiple ranges in the user namespace. In such a case, there won't be any error reported. ## Automatically create user namespace When running as user different than root, an user namespace is automatically created even if it is not specified in the config file. The current user is mapped to the ID 0 in the container, and any additional id specified in the files `/etc/subuid` and `/etc/subgid` is automatically added starting with ID 1. # CGROUP v2 **Note**: cgroup v2 does not yet support control of realtime processes and the cpu controller can only be enabled when all RT processes are in the root cgroup. This will make crun fail while running alongside RT processes. If the cgroup configuration found is for cgroup v1, crun attempts a conversion when running on a cgroup v2 system. These are the OCI resources currently supported with cgroup v2 and how they are converted when needed from the cgroup v1 configuration. ## Memory controller | OCI (x) | cgroup 2 value (y) | conversion | comment | |---|---|---|---| | limit | memory.max | y = x || | swap | memory.swap.max | y = x - memory_limit | the swap limit on cgroup v1 includes the memory usage too | | reservation | memory.low | y = x || ## PIDs controller | OCI (x) | cgroup 2 value (y) | conversion | comment | |---|---|---|---| | limit | pids.max | y = x || ## CPU controller | OCI (x) | cgroup 2 value (y) | conversion | comment | |---|---|---|---| | shares | cpu.weight | y = (1 + ((x - 2) * 9999) / 262142) | convert from [2-262144] to [1-10000]| | period | cpu.max | y = x| period and quota are written together| | quota | cpu.max | y = x| period and quota are written together| ## blkio controller | OCI (x) | cgroup 2 value (y) | conversion | comment | |---|---|---|---| | weight | io.bfq.weight | y = x || | weight_device | io.bfq.weight | y = x || | weight | io.weight (fallback) | y = 1 + (x-10)*9999/990 | convert linearly from [10-1000] to [1-10000] | | weight_device | io.weight (fallback) | y = 1 + (x-10)*9999/990 | convert linearly from [10-1000] to [1-10000] | | rbps | io.max | y=x || | wbps | io.max | y=x || | riops | io.max |y=x || | wiops | io.max |y=x || ## cpuset controller | OCI (x) | cgroup 2 value (y) | conversion | comment | |---|---|---|---| | cpus | cpuset.cpus | y = x || | mems | cpuset.mems | y = x || ## hugetlb controller | OCI (x) | cgroup 2 value (y) | conversion | comment | |---|---|---|---| | .limit_in_bytes | hugetlb..max | y = x || crun-1.16.1/crun.10000644000000000000000000005237514514171717012012 0ustar0000000000000000.nh .TH crun 1 "User Commands" .SH NAME .PP crun - a fast and lightweight OCI runtime .SH SYNOPSIS .PP crun [global options] command [command options] [arguments...] .SH DESCRIPTION .PP crun is a command line program for running Linux containers that follow the Open Container Initiative (OCI) format. .SH COMMANDS .PP \fBcreate\fP Create a container.

The data must be encoded in base64. .PP It is an experimental feature, and the annotation will be removed once it is supported in the OCI runtime specs. .SH \fB\fCrun.oci.keep_original_groups=1\fR .PP If the annotation \fB\fCrun.oci.keep_original_groups\fR is present, then crun will skip the \fB\fCsetgroups\fR syscall that is used to either set the additional groups specified in the OCI configuration, or to reset the list of additional groups if none is specified. .SH \fB\fCrun.oci.pidfd_receiver=PATH\fR .PP It is an experimental feature and will be removed once the feature is in the OCI runtime specs. .PP If present, specify the path to the UNIX socket that will receive the pidfd for the container process. .SH \fB\fCrun.oci.systemd.force_cgroup_v1=/PATH\fR .PP If the annotation \fB\fCrun.oci.systemd.force_cgroup_v1=/PATH\fR is present, then crun will override the specified mount point \fB\fC/PATH\fR with a cgroup v1 mount made of a single hierarchy \fB\fCnone,name=systemd\fR\&. It is useful to run on a cgroup v2 system containers using older versions of systemd that lack support for cgroup v2. .PP \fBNote\fP: Your container host has to have the cgroup v1 mount already present, otherwise this will not work. If you want to run the container rootless, the user it runs under has to have permissions to this mountpoint. .PP For example, as root: .PP .RS .nf mkdir /sys/fs/cgroup/systemd mount cgroup -t cgroup /sys/fs/cgroup/systemd -o none,name=systemd,xattr chown -R the_user.the_user /sys/fs/cgroup/systemd .fi .RE .SH \fB\fCrun.oci.systemd.subgroup=SUBGROUP\fR .PP Override the name for the systemd sub cgroup created under the systemd scope, so the final cgroup will be like: .PP .RS .nf /sys/fs/cgroup/$PATH/$SUBGROUP .fi .RE .PP When it is set to the empty string, a sub cgroup is not created. .PP If not specified, it defaults to \fB\fCcontainer\fR on cgroup v2, and to \fB\fC""\fR on cgroup v1. .PP e.g. .PP .RS .nf /sys/fs/cgroup//system.slice/foo-352700.scope/container .fi .RE .SH \fB\fCrun.oci.delegate-cgroup=DELEGATED-CGROUP\fR .PP If the \fB\fCrun.oci.systemd.subgroup\fR annotation is specified, yet another sub-cgroup is created and the container process is moved here. .PP If a cgroup namespace is used, the cgroup namespace is created before moving the container to the delegated cgroup. .PP .RS .nf /sys/fs/cgroup/$PATH/$SUBGROUP/$DELEGATED-CGROUP .fi .RE .PP The runtime doesn't apply any limit to the \fB\fC$DELEGATED-CGROUP\fR sub-cgroup, the runtime uses only \fB\fC$PATH/$SUBGROUP\fR\&. .PP The container payload fully manages \fB\fC$DELEGATE-CGROUP\fR, the limits applied to \fB\fC$PATH/$SUBGROUP\fR still applies to \fB\fC$DELEGATE-CGROUP\fR\&. .PP Since cgroup delegation is not safe on cgroup v1, this option is supported only on cgroup v2. .SH \fB\fCrun.oci.hooks.stdout=FILE\fR .PP If the annotation \fB\fCrun.oci.hooks.stdout\fR is present, then crun will open the specified file and use it as the stdout for the hook processes. The file is opened in append mode and it is created if it doesn't already exist. .SH \fB\fCrun.oci.hooks.stderr=FILE\fR .PP If the annotation \fB\fCrun.oci.hooks.stderr\fR is present, then crun will open the specified file and use it as the stderr for the hook processes. The file is opened in append mode and it is created if it doesn't already exist. .SH \fB\fCrun.oci.handler=HANDLER\fR .PP It is an experimental feature. .PP If specified, run the specified handler for execing the container. The only supported values are \fB\fCkrun\fR and \fB\fCwasm\fR\&. .RS .IP \(bu 2 \fB\fCkrun\fR: When \fB\fCkrun\fR is specified, the \fB\fClibkrun.so\fR shared object is loaded and it is used to launch the container using libkrun. .IP \(bu 2 \fB\fCwasm\fR: If specified, run the wasm handler for container. Allows running wasm workload natively. Accepts a \fB\fC\&.wasm\fR binary as input and if \fB\fC\&.wat\fR is provided it will be automatically compiled into a wasm module. Stdout of wasm module is relayed back via crun. .RE .SH tmpcopyup mount options .PP If the \fB\fCtmpcopyup\fR option is specified for a tmpfs, then the path that is shadowed by the tmpfs mount is recursively copied up to the tmpfs itself. .SH copy-symlink mount options .PP If the \fB\fCcopy-symlink\fR option is specified, if the source of a bind mount is a symlink, the symlink is recreated at the specified destination instead of attempting a mount that would resolve the symlink itself. If the destination already exists and it is not a symlink with the expected content, crun will return an error. .SH r$FLAG mount options .PP If a \fB\fCr$FLAG\fR mount option is specified then the flag \fB\fC$FLAG\fR is set recursively for each children mount. .PP These flags are supported: .RS .IP \(bu 2 "rro" .IP \(bu 2 "rrw" .IP \(bu 2 "rsuid" .IP \(bu 2 "rnosuid" .IP \(bu 2 "rdev" .IP \(bu 2 "rnodev" .IP \(bu 2 "rexec" .IP \(bu 2 "rnoexec" .IP \(bu 2 "rsync" .IP \(bu 2 "rasync" .IP \(bu 2 "rdirsync" .IP \(bu 2 "rmand" .IP \(bu 2 "rnomand" .IP \(bu 2 "ratime" .IP \(bu 2 "rnoatime" .IP \(bu 2 "rdiratime" .IP \(bu 2 "rnodiratime" .IP \(bu 2 "rrelatime" .IP \(bu 2 "rnorelatime" .IP \(bu 2 "rstrictatime" .IP \(bu 2 "rnostrictatime" .RE .SH idmap mount options .PP If the \fB\fCidmap\fR option is specified then the mount is ID mapped using the container target user namespace. This is an experimental feature and can change at any time without notice. .PP The \fB\fCidmap\fR option supports a custom mapping that can be different than the user namespace used by the container. .PP The mapping can be specified after the \fB\fCidmap\fR option like: \fB\fCidmap=uids=0-1-10#10-11-10;gids=0-100-10\fR\&. .PP For each triplet, the first value is the start of the backing file system IDs that are mapped to the second value on the host. The length of this mapping is given in the third value. .PP Multiple ranges are separated with \fB\fC#\fR\&. .PP These values are written to the \fB\fC/proc/$PID/uid_map\fR and \fB\fC/proc/$PID/gid_map\fR files to create the user namespace for the idmapped mount. .PP The only two options that are currently supported after \fB\fCidmap\fR are \fB\fCuids\fR and \fB\fCgids\fR\&. .PP When a custom mapping is specified, a new user namespace is created for the idmapped mount. .PP If no option is specified, then the container user namespace is used. .PP If the specified mapping is prepended with a '@' then the mapping is considered relative to the container user namespace. The host ID for the mapping is changed to account for the relative position of the container user in the container user namespace. .PP For example, the mapping: \fB\fCuids=@1-3-10\fR, given a configuration like .PP .RS .nf "uidMappings": [ { "containerID": 0, "hostID": 0, "size": 1 }, { "containerID": 1, "hostID": 2, "size": 1000 } ] .fi .RE .PP will be converted to the absolute value \fB\fCuids=1-4-10\fR, where 4 is calculated by adding 3 (container ID in the \fB\fCuids=\fR mapping) and 1 (\fB\fChostID - containerID\fR for the user namespace mapping where \fB\fCcontainerID = 1\fR is found). .PP The current implementation doesn't take into account multiple user namespace ranges, so it is the caller's responsibility to split a mapping if it overlaps multiple ranges in the user namespace. In such a case, there won't be any error reported. .SH Automatically create user namespace .PP When running as user different than root, an user namespace is automatically created even if it is not specified in the config file. The current user is mapped to the ID 0 in the container, and any additional id specified in the files \fB\fC/etc/subuid\fR and \fB\fC/etc/subgid\fR is automatically added starting with ID 1. .SH CGROUP v2 .PP \fBNote\fP: cgroup v2 does not yet support control of realtime processes and the cpu controller can only be enabled when all RT processes are in the root cgroup. This will make crun fail while running alongside RT processes. .PP If the cgroup configuration found is for cgroup v1, crun attempts a conversion when running on a cgroup v2 system. .PP These are the OCI resources currently supported with cgroup v2 and how they are converted when needed from the cgroup v1 configuration. .SH Memory controller .TS allbox; l l l l l l l l . \fB\fCOCI (x)\fR \fB\fCcgroup 2 value (y)\fR \fB\fCconversion\fR \fB\fCcomment\fR limit memory.max y = x swap memory.swap.max y = x - memory_limit T{ the swap limit on cgroup v1 includes the memory usage too T} reservation memory.low y = x .TE .SH PIDs controller .TS allbox; l l l l l l l l . \fB\fCOCI (x)\fR \fB\fCcgroup 2 value (y)\fR \fB\fCconversion\fR \fB\fCcomment\fR limit pids.max y = x .TE .SH CPU controller .TS allbox; l l l l l l l l . \fB\fCOCI (x)\fR \fB\fCcgroup 2 value (y)\fR \fB\fCconversion\fR \fB\fCcomment\fR shares cpu.weight T{ y = (1 + ((x - 2) * 9999) / 262142) T} T{ convert from [2-262144] to [1-10000] T} period cpu.max y = x T{ period and quota are written together T} quota cpu.max y = x T{ period and quota are written together T} .TE .SH blkio controller .TS allbox; l l l l l l l l . \fB\fCOCI (x)\fR \fB\fCcgroup 2 value (y)\fR \fB\fCconversion\fR \fB\fCcomment\fR weight io.bfq.weight y = x weight_device io.bfq.weight y = x weight io.weight (fallback) y = 1 + (x-10)*9999/990 T{ convert linearly from [10-1000] to [1-10000] T} weight_device io.weight (fallback) y = 1 + (x-10)*9999/990 T{ convert linearly from [10-1000] to [1-10000] T} rbps io.max y=x wbps io.max y=x riops io.max y=x wiops io.max y=x .TE .SH cpuset controller .TS allbox; l l l l l l l l . \fB\fCOCI (x)\fR \fB\fCcgroup 2 value (y)\fR \fB\fCconversion\fR \fB\fCcomment\fR cpus cpuset.cpus y = x mems cpuset.mems y = x .TE .SH hugetlb controller .TS allbox; l l l l l l l l . \fB\fCOCI (x)\fR \fB\fCcgroup 2 value (y)\fR \fB\fCconversion\fR \fB\fCcomment\fR \&.limit_in_bytes hugetlb.\&.max y = x .TE crun-1.16.1/libcrun.lds0000664000000000000000000000040113677104573013111 0ustar0000000000000000{ global: /* Not all the libcrun_ functions are exported, only those marked LIBCRUN_PUBLIC. */ libcrun_*; /* libocispec functions */ runtime_spec_*; free_runtime_spec_*; make_runtime_spec_*; local: *; }; crun-1.16.1/krun.1.md0000644000000000000000000000205414504567214012406 0ustar0000000000000000crun 1 "User Commands" ================================================== # NAME krun - crun based OCI runtime using libkrun to run containerized programs in isolated KVM environments # SYNOPSIS krun [global options] command [command options] [arguments...] # DESCRIPTION krun is a sub package of the crun command line program for running Linux containers that follow the Open Container Initiative (OCI) format.

There's no portable way to scope variables in Bourne shell # though, so actually running these functions will sometimes place # results into a variable named after the function, and often use # temporary variables in the '^_G_' namespace.

As a special exception, you may create a larger work that contains part or all of the libocispec parser skeleton and distribute that work under terms of your choice, so long as that work isn't itself a parser generator using the skeleton or a modified version thereof as a parser skeleton. Alternatively, if you modify or redistribute the parser skeleton itself, you may (at your option) remove this special exception, which will cause the skeleton and the resulting libocispec output files to be licensed under the GNU General Public License without this special exception. GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

The mechanisms used are regular community communication on the mailing list about progress, scheduled meetings for issue resolution and release triage, and regularly paced and communicated releases. Releases are proposed and adopted or rejected using the usual [project governance](GOVERNANCE.md) rules and procedures. An anti-pattern that we want to avoid is heavy development or discussions "late cycle" around major releases. We want to build a community that is involved and communicates consistently through all releases instead of relying on "silent periods" as a judge of stability. ## Parallel releases A single project MAY consider several motions to release in parallel. However each motion to release after the initial 0.1.0 MUST be based on a previous release that has already landed. For example, runtime-spec maintainers may propose a v1.0.0-rc2 on the 1st of the month and a v0.9.1 bugfix on the 2nd of the month. They may not propose a v1.0.0-rc3 until the v1.0.0-rc2 is accepted (on the 7th if the vote initiated on the 1st passes). ## Specifications The OCI maintains three categories of projects: specifications, applications, and conformance-testing tools. However, specification releases have special restrictions in the [OCI charter][charter]: * They are the target of backwards compatibility (§7.g), and * They are subject to the OFWa patent grant (§8.d and e). To avoid unfortunate side effects (onerous backwards compatibility requirements or Member resignations), the following additional procedures apply to specification releases: ### Planning a release Every OCI specification project SHOULD hold meetings that involve maintainers reviewing pull requests, debating outstanding issues, and planning releases. This meeting MUST be advertised on the project README and MAY happen on a phone call, video conference, or on IRC. Maintainers MUST send updates to the dev@opencontainers.org with results of these meetings. Before the specification reaches v1.0.0, the meetings SHOULD be weekly. Once a specification has reached v1.0.0, the maintainers may alter the cadence, but a meeting MUST be held within four weeks of the previous meeting. The release plans, corresponding milestones and estimated due dates MUST be published on GitHub (e.g. https://github.com/opencontainers/runtime-spec/milestones). GitHub milestones and issues are only used for community organization and all releases MUST follow the [project governance](GOVERNANCE.md) rules and procedures. ### Timelines Specifications have a variety of different timelines in their lifecycle. * Pre-v1.0.0 specifications SHOULD release on a monthly cadence to garner feedback. * Major specification releases MUST release at least three release candidates spaced a minimum of one week apart. This means a major release like a v1.0.0 or v2.0.0 release will take 1 month at minimum: one week for rc1, one week for rc2, one week for rc3, and one week for the major release itself. Maintainers SHOULD strive to make zero breaking changes during this cycle of release candidates and SHOULD restart the three-candidate count when a breaking change is introduced. For example if a breaking change is introduced in v1.0.0-rc2 then the series would end with v1.0.0-rc4 and v1.0.0. * Minor and patch releases SHOULD be made on an as-needed basis.

For example, namespaces, resource limits, and mounts are all part of the container environment. ## Container namespace On Linux,the [namespaces][namespaces.7] in which the [configured process](config.md#process) executes. ## Features Structure A [JSON][] structure that represents [the implemented features](#features.md) of the [runtime](#runtime). Irrelevant to the actual availability of the features in the host operating system. ## JSON All configuration [JSON][] MUST be encoded in [UTF-8][]. JSON objects MUST NOT include duplicate names. The order of entries in JSON objects is not significant. ## Runtime An implementation of this specification. It reads the [configuration files](#configuration) from a [bundle](#bundle), uses that information to create a [container](#container), launches a process inside the container, and performs other [lifecycle actions](runtime.md). ## Runtime caller An external program to execute a [runtime](#runtime), directly or indirectly. Examples of direct callers include containerd, CRI-O, and Podman. Examples of indirect callers include Docker/Moby and Kubernetes. Runtime callers often execute a runtime via [runc][]-compatible command line interface, however, its interaction interface is currently out of the scope of the Open Container Initiative Runtime Specification. ## Runtime namespace On Linux, the namespaces from which new [container namespaces](#container-namespace) are [created](config-linux.md#namespaces) and from which some configured resources are accessed. [JSON]: https://tools.ietf.org/html/rfc8259 [UTF-8]: http://www.unicode.org/versions/Unicode8.0.0/ch03.pdf [runc]: https://github.com/opencontainers/runc [namespaces.7]: http://man7.org/linux/man-pages/man7/namespaces.7.html crun-1.16.1/libocispec/runtime-spec/config-linux.md0000644000000000000000000012456314432210717020424 0ustar0000000000000000# Linux Container Configuration This document describes the schema for the [Linux-specific section](config.md#platform-specific-configuration) of the [container configuration](config.md). The Linux container specification uses various kernel features like namespaces, cgroups, capabilities, LSM, and filesystem jails to fulfill the spec. ## Default Filesystems The Linux ABI includes both syscalls and several special file paths. Applications expecting a Linux environment will very likely expect these file paths to be set up correctly. The following filesystems SHOULD be made available in each container's filesystem: | Path | Type | | -------- | ------ | | /proc | [proc][] | | /sys | [sysfs][] | | /dev/pts | [devpts][] | | /dev/shm | [tmpfs][] | ## Namespaces A namespace wraps a global system resource in an abstraction that makes it appear to the processes within the namespace that they have their own isolated instance of the global resource. Changes to the global resource are visible to other processes that are members of the namespace, but are invisible to other processes. For more information, see the [namespaces(7)][namespaces.7_2] man page. Namespaces are specified as an array of entries inside the `namespaces` root field. The following parameters can be specified to set up namespaces: * **`type`** *(string, REQUIRED)* - namespace type. The following namespace types SHOULD be supported: * **`pid`** processes inside the container will only be able to see other processes inside the same container or inside the same pid namespace. * **`network`** the container will have its own network stack. * **`mount`** the container will have an isolated mount table. * **`ipc`** processes inside the container will only be able to communicate to other processes inside the same container via system level IPC. * **`uts`** the container will be able to have its own hostname and domain name. * **`user`** the container will be able to remap user and group IDs from the host to local users and groups within the container. * **`cgroup`** the container will have an isolated view of the cgroup hierarchy. * **`time`** the container will be able to have its own clocks. * **`path`** *(string, OPTIONAL)* - namespace file. This value MUST be an absolute path in the [runtime mount namespace](glossary.md#runtime-namespace). The runtime MUST place the container process in the namespace associated with that `path`. The runtime MUST [generate an error](runtime.md#errors) if `path` is not associated with a namespace of type `type`. If `path` is not specified, the runtime MUST create a new [container namespace](glossary.md#container-namespace) of type `type`. If a namespace type is not specified in the `namespaces` array, the container MUST inherit the [runtime namespace](glossary.md#runtime-namespace) of that type. If a `namespaces` field contains duplicated namespaces with same `type`, the runtime MUST [generate an error](runtime.md#errors). ### Example ```json "namespaces": [ { "type": "pid", "path": "/proc/1234/ns/pid" }, { "type": "network", "path": "/var/run/netns/neta" }, { "type": "mount" }, { "type": "ipc" }, { "type": "uts" }, { "type": "user" }, { "type": "cgroup" }, { "type": "time" } ] ``` ## User namespace mappings **`uidMappings`** (array of objects, OPTIONAL) describes the user namespace uid mappings from the host to the container. **`gidMappings`** (array of objects, OPTIONAL) describes the user namespace gid mappings from the host to the container. Each entry has the following structure: * **`containerID`** *(uint32, REQUIRED)* - is the starting uid/gid in the container. * **`hostID`** *(uint32, REQUIRED)* - is the starting uid/gid on the host to be mapped to *containerID*. * **`size`** *(uint32, REQUIRED)* - is the number of ids to be mapped. The runtime SHOULD NOT modify the ownership of referenced filesystems to realize the mapping. Note that the number of mapping entries MAY be limited by the [kernel][user-namespaces]. ### Example ```json "uidMappings": [ { "containerID": 0, "hostID": 1000, "size": 32000 } ], "gidMappings": [ { "containerID": 0, "hostID": 1000, "size": 32000 } ] ``` ## Offset for Time Namespace **`timeOffsets`** (object, OPTIONAL) sets the offset for Time Namespace. For more information see the [time_namespaces][time_namespaces.7]. The name of the clock is the entry key. Entry values are objects with the following properties: * **`secs`** *(int64, OPTIONAL)* - is the offset of clock (in seconds) in the container. * **`nanosecs`** *(uint32, OPTIONAL)* - is the offset of clock (in nanoseconds) in the container. ## Devices **`devices`** (array of objects, OPTIONAL) lists devices that MUST be available in the container. The runtime MAY supply them however it likes (with [`mknod`][mknod.2], by bind mounting from the runtime mount namespace, using symlinks, etc.). Each entry has the following structure: * **`type`** *(string, REQUIRED)* - type of device: `c`, `b`, `u` or `p`. More info in [mknod(1)][mknod.1]. * **`path`** *(string, REQUIRED)* - full path to device inside container. If a [file][] already exists at `path` that does not match the requested device, the runtime MUST generate an error. The path MAY be anywhere in the container filesystem, notably outside of `/dev`. * **`major, minor`** *(int64, REQUIRED unless `type` is `p`)* - [major, minor numbers][devices] for the device. * **`fileMode`** *(uint32, OPTIONAL)* - file mode for the device. You can also control access to devices [with cgroups](#configLinuxDeviceAllowedlist). * **`uid`** *(uint32, OPTIONAL)* - id of device owner in the [container namespace](glossary.md#container-namespace). * **`gid`** *(uint32, OPTIONAL)* - id of device group in the [container namespace](glossary.md#container-namespace). The same `type`, `major` and `minor` SHOULD NOT be used for multiple devices. Containers MAY NOT access any device node that is not either explicitly referenced in the **`devices`** array or listed as being part of the [default devices](#configLinuxDefaultDevices). Rationale: runtimes based on virtual machines need to be able to adjust the node devices, and accessing device nodes that were not adjusted could have undefined behaviour. ### Example ```json "devices": [ { "path": "/dev/fuse", "type": "c", "major": 10, "minor": 229, "fileMode": 438, "uid": 0, "gid": 0 }, { "path": "/dev/sda", "type": "b", "major": 8, "minor": 0, "fileMode": 432, "uid": 0, "gid": 0 } ] ``` ### Default Devices In addition to any devices configured with this setting, the runtime MUST also supply: * [`/dev/null`][null.4] * [`/dev/zero`][zero.4] * [`/dev/full`][full.4] * [`/dev/random`][random.4] * [`/dev/urandom`][random.4] * [`/dev/tty`][tty.4] * `/dev/console` is set up if [`terminal`](config.md#process) is enabled in the config by bind mounting the pseudoterminal pty to `/dev/console`. * [`/dev/ptmx`][pts.4]. A [bind-mount or symlink of the container's `/dev/pts/ptmx`][devpts]. ## Control groups Also known as cgroups, they are used to restrict resource usage for a container and handle device access. cgroups provide controls (through controllers) to restrict cpu, memory, IO, pids, network and RDMA resources for the container. For more information, see the [kernel cgroups documentation][cgroup-v1]. A runtime MAY, during a particular [container operation](runtime.md#operation), such as [create](runtime.md#create), [start](runtime.md#start), or [exec](runtime.md#exec), check if the container cgroup is fit for purpose, and MUST [generate an error](runtime.md#errors) if such a check fails. For example, a frozen cgroup or (for [create](runtime.md#create) operation) a non-empty cgroup. The reason for this is that accepting such configurations could cause container operation outcomes that users may not anticipate or understand, such as operation on one container inadvertently affecting other containers. ### Cgroups Path **`cgroupsPath`** (string, OPTIONAL) path to the cgroups. It can be used to either control the cgroups hierarchy for containers or to run a new process in an existing container. The value of `cgroupsPath` MUST be either an absolute path or a relative path. * In the case of an absolute path (starting with `/`), the runtime MUST take the path to be relative to the cgroups mount point. * In the case of a relative path (not starting with `/`), the runtime MAY interpret the path relative to a runtime-determined location in the cgroups hierarchy. If the value is specified, the runtime MUST consistently attach to the same place in the cgroups hierarchy given the same value of `cgroupsPath`. If the value is not specified, the runtime MAY define the default cgroups path. Runtimes MAY consider certain `cgroupsPath` values to be invalid, and MUST generate an error if this is the case. Implementations of the Spec can choose to name cgroups in any manner. The Spec does not include naming schema for cgroups. The Spec does not support per-controller paths for the reasons discussed in the [cgroupv2 documentation][cgroup-v2]. The cgroups will be created if they don't exist. You can configure a container's cgroups via the `resources` field of the Linux configuration. Do not specify `resources` unless limits have to be updated. For example, to run a new process in an existing container without updating limits, `resources` need not be specified. Runtimes MAY attach the container process to additional cgroup controllers beyond those necessary to fulfill the `resources` settings. ### Cgroup ownership Runtimes MAY, according to the following rules, change (or cause to be changed) the owner of the container's cgroup to the host uid that maps to the value of `process.user.uid` in the [container namespace](glossary.md#container-namespace); that is, the user that will execute the container process. Runtimes SHOULD NOT change the ownership of container cgroups when cgroups v1 is in use. Cgroup delegation is not secure in cgroups v1. A runtime SHOULD NOT change the ownership of a container cgroup unless it will also create a new cgroup namespace for the container. Typically this occurs when the `linux.namespaces` array contains an object with `type` equal to `"cgroup"` and `path` unset. Runtimes SHOULD change the cgroup ownership if and only if the cgroup filesystem is to be mounted read/write; that is, when the configuration's `mounts` array contains an object where: - The `source` field is equal to `"cgroup"` - The `destination` field is equal to `"/sys/fs/cgroup"` - The `options` field does not contain the value `"ro"` If the configuration does not specify such a mount, the runtime SHOULD NOT change the cgroup ownership. A runtime that changes the cgroup ownership SHOULD only change the ownership of the container's cgroup directory and files within that directory that are listed in `/sys/kernel/cgroup/delegate`. See `cgroups(7)` for details about this file. Note that not all files listed in `/sys/kernel/cgroup/delegate` necessarily exist in every cgroup. Runtimes MUST NOT fail in this scenario, and SHOULD change the ownership of the listed files that do exist in the cgroup. If the `/sys/kernel/cgroup/delegate` file does not exist, the runtime MUST fall back to using the following list of files: ``` cgroup.procs cgroup.subtree_control cgroup.threads ``` The runtime SHOULD NOT change the ownership of any other files. Changing other files may allow the container to elevate its own resource limits or perform other unwanted behaviour. ### Example ```json "cgroupsPath": "/myRuntime/myContainer", "resources": { "memory": { "limit": 100000, "reservation": 200000 }, "devices": [ { "allow": false, "access": "rwm" } ] } ``` ### Allowed Device list **`devices`** (array of objects, OPTIONAL) configures the [allowed device list][cgroup-v1-devices]. The runtime MUST apply entries in the listed order. Each entry has the following structure: * **`allow`** *(boolean, REQUIRED)* - whether the entry is allowed or denied. * **`type`** *(string, OPTIONAL)* - type of device: `a` (all), `c` (char), or `b` (block). Unset values mean "all", mapping to `a`. * **`major, minor`** *(int64, OPTIONAL)* - [major, minor numbers][devices] for the device. Unset values mean "all", mapping to [`*` in the filesystem API][cgroup-v1-devices]. * **`access`** *(string, OPTIONAL)* - cgroup permissions for device. A composition of `r` (read), `w` (write), and `m` (mknod). #### Example ```json "devices": [ { "allow": false, "access": "rwm" }, { "allow": true, "type": "c", "major": 10, "minor": 229, "access": "rw" }, { "allow": true, "type": "b", "major": 8, "minor": 0, "access": "r" } ] ``` ### Memory **`memory`** (object, OPTIONAL) represents the cgroup subsystem `memory` and it's used to set limits on the container's memory usage. For more information, see the kernel cgroups documentation about [memory][cgroup-v1-memory]. Values for memory specify the limit in bytes, or `-1` for unlimited memory. * **`limit`** *(int64, OPTIONAL)* - sets limit of memory usage * **`reservation`** *(int64, OPTIONAL)* - sets soft limit of memory usage * **`swap`** *(int64, OPTIONAL)* - sets limit of memory+Swap usage * **`kernel`** *(int64, OPTIONAL, NOT RECOMMENDED)* - sets hard limit for kernel memory * **`kernelTCP`** *(int64, OPTIONAL, NOT RECOMMENDED)* - sets hard limit for kernel TCP buffer memory The following properties do not specify memory limits, but are covered by the `memory` controller: * **`swappiness`** *(uint64, OPTIONAL)* - sets swappiness parameter of vmscan (See sysctl's vm.swappiness) The values are from 0 to 100. Higher means more swappy. * **`disableOOMKiller`** *(bool, OPTIONAL)* - enables or disables the OOM killer. If enabled (`false`), tasks that attempt to consume more memory than they are allowed are immediately killed by the OOM killer. The OOM killer is enabled by default in every cgroup using the `memory` subsystem. To disable it, specify a value of `true`. * **`useHierarchy`** *(bool, OPTIONAL)* - enables or disables hierarchical memory accounting. If enabled (`true`), child cgroups will share the memory limits of this cgroup. * **`checkBeforeUpdate`** *(bool, OPTIONAL)* - enables container memory usage check before setting a new limit. If enabled (`true`), runtime MAY check if a new memory limit is lower than the current usage, and MUST reject the new limit. Practically, when cgroup v1 is used, the kernel rejects the limit lower than the current usage, and when cgroup v2 is used, an OOM killer is invoked. This setting can be used on cgroup v2 to mimic the cgroup v1 behavior. #### Example ```json "memory": { "limit": 536870912, "reservation": 536870912, "swap": 536870912, "kernel": -1, "kernelTCP": -1, "swappiness": 0, "disableOOMKiller": false } ``` ### CPU **`cpu`** (object, OPTIONAL) represents the cgroup subsystems `cpu` and `cpusets`. For more information, see the kernel cgroups documentation about [cpusets][cgroup-v1-cpusets]. The following parameters can be specified to set up the controller: * **`shares`** *(uint64, OPTIONAL)* - specifies a relative share of CPU time available to the tasks in a cgroup * **`quota`** *(int64, OPTIONAL)* - specifies the total amount of time in microseconds for which all tasks in a cgroup can run during one period (as defined by **`period`** below) If specified with any (valid) positive value, it MUST be no smaller than `burst` (runtimes MAY generate an error). * **`burst`** *(uint64, OPTIONAL)* - specifies the maximum amount of accumulated time in microseconds for which all tasks in a cgroup can run additionally for burst during one period (as defined by **`period`** below) If specified, this value MUST be no larger than any positive `quota` (runtimes MAY generate an error). * **`period`** *(uint64, OPTIONAL)* - specifies a period of time in microseconds for how regularly a cgroup's access to CPU resources should be reallocated (CFS scheduler only) * **`realtimeRuntime`** *(int64, OPTIONAL)* - specifies a period of time in microseconds for the longest continuous period in which the tasks in a cgroup have access to CPU resources * **`realtimePeriod`** *(uint64, OPTIONAL)* - same as **`period`** but applies to realtime scheduler only * **`cpus`** *(string, OPTIONAL)* - list of CPUs the container will run in * **`mems`** *(string, OPTIONAL)* - list of Memory Nodes the container will run in * **`idle`** *(int64, OPTIONAL)* - cgroups are configured with minimum weight, 0: default behavior, 1: SCHED_IDLE. #### Example ```json "cpu": { "shares": 1024, "quota": 1000000, "burst": 1000000, "period": 500000, "realtimeRuntime": 950000, "realtimePeriod": 1000000, "cpus": "2-3", "mems": "0-7", "idle": 0 } ``` ### Block IO **`blockIO`** (object, OPTIONAL) represents the cgroup subsystem `blkio` which implements the block IO controller. For more information, see the kernel cgroups documentation about [blkio][cgroup-v1-blkio] of cgroup v1 or [io][cgroup-v2-io] of cgroup v2, . Note that I/O throttling settings in cgroup v1 apply only to Direct I/O due to kernel implementation constraints, while this limitation does not exist in cgroup v2. The following parameters can be specified to set up the controller: * **`weight`** *(uint16, OPTIONAL)* - specifies per-cgroup weight. This is default weight of the group on all devices until and unless overridden by per-device rules. * **`leafWeight`** *(uint16, OPTIONAL)* - equivalents of `weight` for the purpose of deciding how much weight tasks in the given cgroup has while competing with the cgroup's child cgroups. * **`weightDevice`** *(array of objects, OPTIONAL)* - an array of per-device bandwidth weights. Each entry has the following structure: * **`major, minor`** *(int64, REQUIRED)* - major, minor numbers for device. For more information, see the [mknod(1)][mknod.1] man page. * **`weight`** *(uint16, OPTIONAL)* - bandwidth weight for the device. * **`leafWeight`** *(uint16, OPTIONAL)* - bandwidth weight for the device while competing with the cgroup's child cgroups, CFQ scheduler only You MUST specify at least one of `weight` or `leafWeight` in a given entry, and MAY specify both. * **`throttleReadBpsDevice`**, **`throttleWriteBpsDevice`** *(array of objects, OPTIONAL)* - an array of per-device bandwidth rate limits. Each entry has the following structure: * **`major, minor`** *(int64, REQUIRED)* - major, minor numbers for device. For more information, see the [mknod(1)][mknod.1] man page. * **`rate`** *(uint64, REQUIRED)* - bandwidth rate limit in bytes per second for the device * **`throttleReadIOPSDevice`**, **`throttleWriteIOPSDevice`** *(array of objects, OPTIONAL)* - an array of per-device IO rate limits. Each entry has the following structure: * **`major, minor`** *(int64, REQUIRED)* - major, minor numbers for device. For more information, see the [mknod(1)][mknod.1] man page. * **`rate`** *(uint64, REQUIRED)* - IO rate limit for the device #### Example ```json "blockIO": { "weight": 10, "leafWeight": 10, "weightDevice": [ { "major": 8, "minor": 0, "weight": 500, "leafWeight": 300 }, { "major": 8, "minor": 16, "weight": 500 } ], "throttleReadBpsDevice": [ { "major": 8, "minor": 0, "rate": 600 } ], "throttleWriteIOPSDevice": [ { "major": 8, "minor": 16, "rate": 300 } ] } ``` ### Huge page limits **`hugepageLimits`** (array of objects, OPTIONAL) represents the `hugetlb` controller which allows to limit the HugeTLB reservations (if supported) or usage (page fault). By default if supported by the kernel, `hugepageLimits` defines the hugepage sizes and limits for HugeTLB controller reservation accounting, which allows to limit the HugeTLB reservations per control group and enforces the controller limit at reservation time and at the fault of HugeTLB memory for which no reservation exists. Otherwise if not supported by the kernel, this should fallback to the page fault accounting, which allows users to limit the HugeTLB usage (page fault) per control group and enforces the limit during page fault. Note that reservation limits are superior to page fault limits, since reservation limits are enforced at reservation time (on mmap or shget), and never causes the application to get SIGBUS signal if the memory was reserved before hand. This allows for easier fallback to alternatives such as non-HugeTLB memory for example. In the case of page fault accounting, it's very hard to avoid processes getting SIGBUS since the sysadmin needs precisely know the HugeTLB usage of all the tasks in the system and make sure there is enough pages to satisfy all requests. Avoiding tasks getting SIGBUS on overcommited systems is practically impossible with page fault accounting. For more information, see the kernel cgroups documentation about [HugeTLB][cgroup-v1-hugetlb]. Each entry has the following structure: * **`pageSize`** *(string, REQUIRED)* - hugepage size. The value has the format `B` (64KB, 2MB, 1GB), and must match the `` of the corresponding control file found in `/sys/fs/cgroup/hugetlb/hugetlb..rsvd.limit_in_bytes` (if hugetlb_cgroup reservation is supported) or `/sys/fs/cgroup/hugetlb/hugetlb..limit_in_bytes` (if not supported). Values of `` are intended to be parsed using base 1024 ("1KB" = 1024, "1MB" = 1048576, etc). * **`limit`** *(uint64, REQUIRED)* - limit in bytes of *hugepagesize* HugeTLB reservations (if supported) or usage. #### Example ```json "hugepageLimits": [ { "pageSize": "2MB", "limit": 209715200 }, { "pageSize": "64KB", "limit": 1000000 } ] ``` ### Network **`network`** (object, OPTIONAL) represents the cgroup subsystems `net_cls` and `net_prio`. For more information, see the kernel cgroups documentations about [net\_cls cgroup][cgroup-v1-net-cls] and [net\_prio cgroup][cgroup-v1-net-prio]. The following parameters can be specified to set up the controller: * **`classID`** *(uint32, OPTIONAL)* - is the network class identifier the cgroup's network packets will be tagged with * **`priorities`** *(array of objects, OPTIONAL)* - specifies a list of objects of the priorities assigned to traffic originating from processes in the group and egressing the system on various interfaces. The following parameters can be specified per-priority: * **`name`** *(string, REQUIRED)* - interface name in [runtime network namespace](glossary.md#runtime-namespace) * **`priority`** *(uint32, REQUIRED)* - priority applied to the interface #### Example ```json "network": { "classID": 1048577, "priorities": [ { "name": "eth0", "priority": 500 }, { "name": "eth1", "priority": 1000 } ] } ``` ### PIDs **`pids`** (object, OPTIONAL) represents the cgroup subsystem `pids`. For more information, see the kernel cgroups documentation about [pids][cgroup-v1-pids]. The following parameters can be specified to set up the controller: * **`limit`** *(int64, REQUIRED)* - specifies the maximum number of tasks in the cgroup #### Example ```json "pids": { "limit": 32771 } ``` ### RDMA **`rdma`** (object, OPTIONAL) represents the cgroup subsystem `rdma`. For more information, see the kernel cgroups documentation about [rdma][cgroup-v1-rdma]. The name of the device to limit is the entry key. Entry values are objects with the following properties: * **`hcaHandles`** *(uint32, OPTIONAL)* - specifies the maximum number of hca_handles in the cgroup * **`hcaObjects`** *(uint32, OPTIONAL)* - specifies the maximum number of hca_objects in the cgroup You MUST specify at least one of the `hcaHandles` or `hcaObjects` in a given entry, and MAY specify both. #### Example ```json "rdma": { "mlx5_1": { "hcaHandles": 3, "hcaObjects": 10000 }, "mlx4_0": { "hcaObjects": 1000 }, "rxe3": { "hcaObjects": 10000 } } ``` ## Unified **`unified`** (object, OPTIONAL) allows cgroup v2 parameters to be to be set and modified for the container. Each key in the map refers to a file in the cgroup unified hierarchy. The OCI runtime MUST ensure that the needed cgroup controllers are enabled for the cgroup. Configuration unknown to the runtime MUST still be written to the relevant file. The runtime MUST generate an error when the configuration refers to a cgroup controller that is not present or that cannot be enabled. ### Example ```json "unified": { "io.max": "259:0 rbps=2097152 wiops=120\n253:0 rbps=2097152 wiops=120", "hugetlb.1GB.max": "1073741824" } ``` If a controller is enabled on the cgroup v2 hierarchy but the configuration is provided for the cgroup v1 equivalent controller, the runtime MAY attempt a conversion. If the conversion is not possible the runtime MUST generate an error. ## IntelRdt **`intelRdt`** (object, OPTIONAL) represents the [Intel Resource Director Technology][intel-rdt-cat-kernel-interface]. If `intelRdt` is set, the runtime MUST write the container process ID to the `tasks` file in a proper sub-directory in a mounted `resctrl` pseudo-filesystem. That sub-directory name is specified by `closID` parameter. If no mounted `resctrl` pseudo-filesystem is available in the [runtime mount namespace](glossary.md#runtime-namespace), the runtime MUST [generate an error](runtime.md#errors). If `intelRdt` is not set, the runtime MUST NOT manipulate any `resctrl` pseudo-filesystems. The following parameters can be specified for the container: * **`closID`** *(string, OPTIONAL)* - specifies the identity for RDT Class of Service (CLOS). * **`l3CacheSchema`** *(string, OPTIONAL)* - specifies the schema for L3 cache id and capacity bitmask (CBM). The value SHOULD start with `L3:` and SHOULD NOT contain newlines. * **`memBwSchema`** *(string, OPTIONAL)* - specifies the schema of memory bandwidth per L3 cache id. The value MUST start with `MB:` and MUST NOT contain newlines. The following rules on parameters MUST be applied: * If both `l3CacheSchema` and `memBwSchema` are set, runtimes MUST write the combined value to the `schemata` file in that sub-directory discussed in `closID`. * If `l3CacheSchema` contains a line beginning with `MB:`, the value written to `schemata` file MUST be the non-`MB:` line(s) from `l3CacheSchema` and the line from `memBWSchema`. * If either `l3CacheSchema` or `memBwSchema` is set, runtimes MUST write the value to the `schemata` file in the that sub-directory discussed in `closID`. * If neither `l3CacheSchema` nor `memBwSchema` is set, runtimes MUST NOT write to `schemata` files in any `resctrl` pseudo-filesystems. * If `closID` is not set, runtimes MUST use the container ID from [`start`](runtime.md#start) and create the `` directory. * If `closID` is set, `l3CacheSchema` and/or `memBwSchema` is set * if `closID` directory in a mounted `resctrl` pseudo-filesystem doesn't exist, the runtimes MUST create it. * if `closID` directory in a mounted `resctrl` pseudo-filesystem exists, runtimes MUST compare `l3CacheSchema` and/or `memBwSchema` value with `schemata` file, and [generate an error](runtime.md#errors) if doesn't match. * If `closID` is set, and neither of `l3CacheSchema` and `memBwSchema` are set, runtime MUST check if corresponding pre-configured directory `closID` is present in mounted `resctrl`. If such pre-configured directory `closID` exists, runtime MUST assign container to this `closID` and [generate an error](runtime.md#errors) if directory does not exist. * **`enableCMT`** *(boolean, OPTIONAL)* - specifies if Intel RDT CMT should be enabled: * CMT (Cache Monitoring Technology) supports monitoring of the last-level cache (LLC) occupancy for the container. * **`enableMBM`** *(boolean, OPTIONAL)* - specifies if Intel RDT MBM should be enabled: * MBM (Memory Bandwidth Monitoring) supports monitoring of total and local memory bandwidth for the container. ### Example Consider a two-socket machine with two L3 caches where the default CBM is 0x7ff and the max CBM length is 11 bits, and minimum memory bandwidth of 10% with a memory bandwidth granularity of 10%. Tasks inside the container only have access to the "upper" 7/11 of L3 cache on socket 0 and the "lower" 5/11 L3 cache on socket 1, and may use a maximum memory bandwidth of 20% on socket 0 and 70% on socket 1. ```json "linux": { "intelRdt": { "closID": "guaranteed_group", "l3CacheSchema": "L3:0=7f0;1=1f", "memBwSchema": "MB:0=20;1=70" } } ``` ## Sysctl **`sysctl`** (object, OPTIONAL) allows kernel parameters to be modified at runtime for the container. For more information, see the [sysctl(8)][sysctl.8] man page. ### Example ```json "sysctl": { "net.ipv4.ip_forward": "1", "net.core.somaxconn": "256" } ``` ## Seccomp Seccomp provides application sandboxing mechanism in the Linux kernel. Seccomp configuration allows one to configure actions to take for matched syscalls and furthermore also allows matching on values passed as arguments to syscalls. For more information about Seccomp, see [Seccomp][seccomp] kernel documentation. The actions, architectures, and operators are strings that match the definitions in seccomp.h from [libseccomp][] and are translated to corresponding values. **`seccomp`** (object, OPTIONAL) The following parameters can be specified to set up seccomp: * **`defaultAction`** *(string, REQUIRED)* - the default action for seccomp. Allowed values are the same as `syscalls[].action`. * **`defaultErrnoRet`** *(uint, OPTIONAL)* - the errno return code to use. Some actions like `SCMP_ACT_ERRNO` and `SCMP_ACT_TRACE` allow to specify the errno code to return. When the action doesn't support an errno, the runtime MUST print and error and fail. If not specified then its default value is `EPERM`. * **`architectures`** *(array of strings, OPTIONAL)* - the architecture used for system calls. A valid list of constants as of libseccomp v2.5.0 is shown below. * `SCMP_ARCH_X86` * `SCMP_ARCH_X86_64` * `SCMP_ARCH_X32` * `SCMP_ARCH_ARM` * `SCMP_ARCH_AARCH64` * `SCMP_ARCH_MIPS` * `SCMP_ARCH_MIPS64` * `SCMP_ARCH_MIPS64N32` * `SCMP_ARCH_MIPSEL` * `SCMP_ARCH_MIPSEL64` * `SCMP_ARCH_MIPSEL64N32` * `SCMP_ARCH_PPC` * `SCMP_ARCH_PPC64` * `SCMP_ARCH_PPC64LE` * `SCMP_ARCH_S390` * `SCMP_ARCH_S390X` * `SCMP_ARCH_PARISC` * `SCMP_ARCH_PARISC64` * `SCMP_ARCH_RISCV64` * **`flags`** *(array of strings, OPTIONAL)* - list of flags to use with seccomp(2). A valid list of constants is shown below. * `SECCOMP_FILTER_FLAG_TSYNC` * `SECCOMP_FILTER_FLAG_LOG` * `SECCOMP_FILTER_FLAG_SPEC_ALLOW` * `SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV` * **`listenerPath`** *(string, OPTIONAL)* - specifies the path of UNIX domain socket over which the runtime will send the [container process state](#containerprocessstate) data structure when the `SCMP_ACT_NOTIFY` action is used. This socket MUST use `AF_UNIX` domain and `SOCK_STREAM` type. The runtime MUST send exactly one [container process state](#containerprocessstate) per connection. The connection MUST NOT be reused and it MUST be closed after sending a seccomp state. If sending to this socket fails, the runtime MUST [generate an error](runtime.md#errors). If the `SCMP_ACT_NOTIFY` action is not used this value is ignored. The runtime sends the following file descriptors using `SCM_RIGHTS` and set their names in the `fds` array of the [container process state](#containerprocessstate): * **`seccompFd`** (string, REQUIRED) is the seccomp file descriptor returned by the seccomp syscall. * **`listenerMetadata`** *(string, OPTIONAL)* - specifies an opaque data to pass to the seccomp agent. This string will be sent as the `metadata` field in the [container process state](#containerprocessstate). This field MUST NOT be set if `listenerPath` is not set. * **`syscalls`** *(array of objects, OPTIONAL)* - match a syscall in seccomp. While this property is OPTIONAL, some values of `defaultAction` are not useful without `syscalls` entries. For example, if `defaultAction` is `SCMP_ACT_KILL` and `syscalls` is empty or unset, the kernel will kill the container process on its first syscall. Each entry has the following structure: * **`names`** *(array of strings, REQUIRED)* - the names of the syscalls. `names` MUST contain at least one entry. * **`action`** *(string, REQUIRED)* - the action for seccomp rules. A valid list of constants as of libseccomp v2.5.0 is shown below. * `SCMP_ACT_KILL` * `SCMP_ACT_KILL_PROCESS` * `SCMP_ACT_KILL_THREAD` * `SCMP_ACT_TRAP` * `SCMP_ACT_ERRNO` * `SCMP_ACT_TRACE` * `SCMP_ACT_ALLOW` * `SCMP_ACT_LOG` * `SCMP_ACT_NOTIFY` * **`errnoRet`** *(uint, OPTIONAL)* - the errno return code to use. Some actions like `SCMP_ACT_ERRNO` and `SCMP_ACT_TRACE` allow to specify the errno code to return. When the action doesn't support an errno, the runtime MUST print and error and fail. If not specified its default value is `EPERM`. * **`args`** *(array of objects, OPTIONAL)* - the specific syscall in seccomp. Each entry has the following structure: * **`index`** *(uint, REQUIRED)* - the index for syscall arguments in seccomp. * **`value`** *(uint64, REQUIRED)* - the value for syscall arguments in seccomp. * **`valueTwo`** *(uint64, OPTIONAL)* - the value for syscall arguments in seccomp. * **`op`** *(string, REQUIRED)* - the operator for syscall arguments in seccomp. A valid list of constants as of libseccomp v2.3.2 is shown below. * `SCMP_CMP_NE` * `SCMP_CMP_LT` * `SCMP_CMP_LE` * `SCMP_CMP_EQ` * `SCMP_CMP_GE` * `SCMP_CMP_GT` * `SCMP_CMP_MASKED_EQ` ### Example ```json "seccomp": { "defaultAction": "SCMP_ACT_ALLOW", "architectures": [ "SCMP_ARCH_X86", "SCMP_ARCH_X32" ], "syscalls": [ { "names": [ "getcwd", "chmod" ], "action": "SCMP_ACT_ERRNO" } ] } ``` ### The Container Process State The container process state is a data structure passed via a UNIX socket. The container runtime MUST send the container process state over the UNIX socket as regular payload serialized in JSON and file descriptors MUST be sent using `SCM_RIGHTS`. The container runtime MAY use several `sendmsg(2)` calls to send the aforementioned data. If more than one `sendmsg(2)` is used, the file descriptors MUST be sent only in the first call. The container process state includes the following properties: * **`ociVersion`** (string, REQUIRED) is version of the Open Container Initiative Runtime Specification with which the container process state complies. * **`fds`** (array, OPTIONAL) is a string array containing the names of the file descriptors passed. The index of the name in this array corresponds to index of the file descriptors in the `SCM_RIGHTS` array. * **`pid`** (int, REQUIRED) is the container process ID, as seen by the runtime. * **`metadata`** (string, OPTIONAL) opaque metadata. * **`state`** ([state](runtime.md#state), REQUIRED) is the state of the container. Example sending a single `seccompFd` file descriptor in the `SCM_RIGHTS` array: ```json { "ociVersion": "1.0.2", "fds": [ "seccompFd" ], "pid": 4422, "metadata": "MKNOD=/dev/null,/dev/net/tun;BPF_MAP_TYPES=hash,array", "state": { "ociVersion": "1.0.2", "id": "oci-container1", "status": "creating", "pid": 4422, "bundle": "/containers/redis", "annotations": { "myKey": "myValue" } } } ``` ## Rootfs Mount Propagation **`rootfsPropagation`** (string, OPTIONAL) sets the rootfs's mount propagation. Its value is either `shared`, `slave`, `private` or `unbindable`. It's worth noting that a peer group is defined as a group of VFS mounts that propagate events to each other. A nested container is defined as a container launched inside an existing container. * **`shared`**: the rootfs mount belongs to a new peer group. This means that further mounts (e.g. nested containers) will also belong to that peer group and will propagate events to the rootfs. Note this does not mean that it's shared with the host. * **`slave`**: the rootfs mount receives propagation events from the host (e.g. if something is mounted on the host it will also appear in the container) but not the other way around. * **`private`**: the rootfs mount doesn't receive mount propagation events from the host and further mounts in nested containers will be isolated from the host and from the rootfs (even if the nested container `rootfsPropagation` option is shared). * **`unbindable`**: the rootfs mount is a private mount that cannot be bind-mounted. The [Shared Subtrees][sharedsubtree] article in the kernel documentation has more information about mount propagation. ### Example ```json "rootfsPropagation": "slave", ``` ## Masked Paths **`maskedPaths`** (array of strings, OPTIONAL) will mask over the provided paths inside the container so that they cannot be read. The values MUST be absolute paths in the [container namespace](glossary.md#container_namespace). ### Example ```json "maskedPaths": [ "/proc/kcore" ] ``` ## Readonly Paths **`readonlyPaths`** (array of strings, OPTIONAL) will set the provided paths as readonly inside the container. The values MUST be absolute paths in the [container namespace](glossary.md#container-namespace). ### Example ```json "readonlyPaths": [ "/proc/sys" ] ``` ## Mount Label **`mountLabel`** (string, OPTIONAL) will set the Selinux context for the mounts in the container. ### Example ```json "mountLabel": "system_u:object_r:svirt_sandbox_file_t:s0:c715,c811" ``` ## Personality **`personality`** (object, OPTIONAL) sets the Linux execution personality. For more information see the [personality][personality.2] syscall documentation. As most of the options are obsolete and rarely used, and some reduce security, the currently supported set is a small subset of the available options. * **`domain`** *(string, REQUIRED)* - the execution domain. The valid list of constants is shown below. `LINUX32` will set the `uname` system call to show a 32 bit CPU type, such as `i686`. * `LINUX` * `LINUX32` * **`flags`** *(array of strings, OPTIONAL)* - the additional flags to apply. Currently no flag values are supported.

Whether other entities using the same, or other, instance of the runtime can see that container is out of scope of this specification. ## State The state of a container includes the following properties: * **`ociVersion`** (string, REQUIRED) is version of the Open Container Initiative Runtime Specification with which the state complies. * **`id`** (string, REQUIRED) is the container's ID. This MUST be unique across all containers on this host. There is no requirement that it be unique across hosts. * **`status`** (string, REQUIRED) is the runtime state of the container. The value MAY be one of: * `creating`: the container is being created (step 2 in the [lifecycle](#lifecycle)) * `created`: the runtime has finished the [create operation](#create) (after step 2 in the [lifecycle](#lifecycle)), and the container process has neither exited nor executed the user-specified program * `running`: the container process has executed the user-specified program but has not exited (after step 8 in the [lifecycle](#lifecycle)) * `stopped`: the container process has exited (step 10 in the [lifecycle](#lifecycle)) Additional values MAY be defined by the runtime, however, they MUST be used to represent new runtime states not defined above. * **`pid`** (int, REQUIRED when `status` is `created` or `running` on Linux, OPTIONAL on other platforms) is the ID of the container process. For hooks executed in the runtime namespace, it is the pid as seen by the runtime. For hooks executed in the container namespace, it is the pid as seen by the container. * **`bundle`** (string, REQUIRED) is the absolute path to the container's bundle directory. This is provided so that consumers can find the container's configuration and root filesystem on the host. * **`annotations`** (map, OPTIONAL) contains the list of annotations associated with the container. If no annotations were provided then this property MAY either be absent or an empty map. The state MAY include additional properties. When serialized in JSON, the format MUST adhere to the JSON Schema [`schema/state-schema.json`](schema/state-schema.json). See [Query State](#query-state) for information on retrieving the state of a container. ### Example ```json { "ociVersion": "0.2.0", "id": "oci-container1", "status": "running", "pid": 4422, "bundle": "/containers/redis", "annotations": { "myKey": "myValue" } } ``` ## Lifecycle The lifecycle describes the timeline of events that happen from when a container is created to when it ceases to exist. 1. OCI compliant runtime's [`create`](runtime.md#create) command is invoked with a reference to the location of the bundle and a unique identifier. 2. The container's runtime environment MUST be created according to the configuration in [`config.json`](config.md). If the runtime is unable to create the environment specified in the [`config.json`](config.md), it MUST [generate an error](#errors). While the resources requested in the [`config.json`](config.md) MUST be created, the user-specified program (from [`process`](config.md#process)) MUST NOT be run at this time. Any updates to [`config.json`](config.md) after this step MUST NOT affect the container. 3. The [`prestart` hooks](config.md#prestart) MUST be invoked by the runtime. If any `prestart` hook fails, the runtime MUST [generate an error](#errors), stop the container, and continue the lifecycle at step 12. 4. The [`createRuntime` hooks](config.md#createRuntime-hooks) MUST be invoked by the runtime. If any `createRuntime` hook fails, the runtime MUST [generate an error](#errors), stop the container, and continue the lifecycle at step 12. 5. The [`createContainer` hooks](config.md#createContainer-hooks) MUST be invoked by the runtime. If any `createContainer` hook fails, the runtime MUST [generate an error](#errors), stop the container, and continue the lifecycle at step 12. 6. Runtime's [`start`](runtime.md#start) command is invoked with the unique identifier of the container. 7. The [`startContainer` hooks](config.md#startContainer-hooks) MUST be invoked by the runtime. If any `startContainer` hook fails, the runtime MUST [generate an error](#errors), stop the container, and continue the lifecycle at step 12. 8. The runtime MUST run the user-specified program, as specified by [`process`](config.md#process). 9. The [`poststart` hooks](config.md#poststart) MUST be invoked by the runtime. If any `poststart` hook fails, the runtime MUST [log a warning](#warnings), but the remaining hooks and lifecycle continue as if the hook had succeeded. 10. The container process exits. This MAY happen due to erroring out, exiting, crashing or the runtime's [`kill`](runtime.md#kill) operation being invoked. 11. Runtime's [`delete`](runtime.md#delete) command is invoked with the unique identifier of the container. 12. The container MUST be destroyed by undoing the steps performed during create phase (step 2). 13. The [`poststop` hooks](config.md#poststop) MUST be invoked by the runtime. If any `poststop` hook fails, the runtime MUST [log a warning](#warnings), but the remaining hooks and lifecycle continue as if the hook had succeeded. ## Errors In cases where the specified operation generates an error, this specification does not mandate how, or even if, that error is returned or exposed to the user of an implementation. Unless otherwise stated, generating an error MUST leave the state of the environment as if the operation were never attempted - modulo any possible trivial ancillary changes such as logging. ## Warnings In cases where the specified operation logs a warning, this specification does not mandate how, or even if, that warning is returned or exposed to the user of an implementation. Unless otherwise stated, logging a warning does not change the flow of the operation; it MUST continue as if the warning had not been logged. ## Operations Unless otherwise stated, runtimes MUST support the following operations. Note: these operations are not specifying any command-line APIs, and the parameters are inputs for general operations. ### Query State `state ` This operation MUST [generate an error](#errors) if it is not provided the ID of a container. Attempting to query a container that does not exist MUST [generate an error](#errors). This operation MUST return the state of a container as specified in the [State](#state) section. ### Create `create ` This operation MUST [generate an error](#errors) if it is not provided a path to the bundle and the container ID to associate with the container. If the ID provided is not unique across all containers within the scope of the runtime, or is not valid in any other way, the implementation MUST [generate an error](#errors) and a new container MUST NOT be created. This operation MUST create a new container. All of the properties configured in [`config.json`](config.md) except for [`process`](config.md#process) MUST be applied. [`process.args`](config.md#process) MUST NOT be applied until triggered by the [`start`](#start) operation. The remaining `process` properties MAY be applied by this operation. If the runtime cannot apply a property as specified in the [configuration](config.md), it MUST [generate an error](#errors) and a new container MUST NOT be created. The runtime MAY validate `config.json` against this spec, either generically or with respect to the local system capabilities, before creating the container ([step 2](#lifecycle)). [Runtime callers](glossary.md#runtime-caller) who are interested in pre-create validation can run [bundle-validation tools](implementations.md#testing--tools) before invoking the create operation. Any changes made to the [`config.json`](config.md) file after this operation will not have an effect on the container. ### Start `start ` This operation MUST [generate an error](#errors) if it is not provided the container ID. Attempting to `start` a container that is not [`created`](#state) MUST have no effect on the container and MUST [generate an error](#errors). This operation MUST run the user-specified program as specified by [`process`](config.md#process). This operation MUST generate an error if `process` was not set. ### Kill `kill ` This operation MUST [generate an error](#errors) if it is not provided the container ID. Attempting to send a signal to a container that is neither [`created` nor `running`](#state) MUST have no effect on the container and MUST [generate an error](#errors). This operation MUST send the specified signal to the container process. ### Delete `delete ` This operation MUST [generate an error](#errors) if it is not provided the container ID. Attempting to `delete` a container that is not [`stopped`](#state) MUST have no effect on the container and MUST [generate an error](#errors). Deleting a container MUST delete the resources that were created during the `create` step. Note that resources associated with the container, but not created by this container, MUST NOT be deleted. Once a container is deleted its ID MAY be used by a subsequent container. ## Hooks Many of the operations specified in this specification have "hooks" that allow for additional actions to be taken before or after each operation. See [runtime configuration for hooks](./config.md#posix-platform-hooks) for more information. crun-1.16.1/libocispec/runtime-spec/README.md0000644000000000000000000001543514614670026016761 0ustar0000000000000000# Open Container Initiative Runtime Specification [![GitHub Actions status](https://github.com/opencontainers/runtime-spec/workflows/build/badge.svg)](https://github.com/opencontainers/runtime-spec/actions?query=workflow%3Abuild) The [Open Container Initiative][oci] develops specifications for standards on Operating System process and application containers. The specification can be found [here](spec.md). ## Table of Contents Additional documentation about how this group operates: - [Code of Conduct][code-of-conduct] - [Style and Conventions](style.md) - [Implementations](implementations.md) - [Releases](RELEASES.md) - [charter][charter] ## Use Cases To provide context for users the following section gives example use cases for each part of the spec. ### Application Bundle Builders Application bundle builders can create a [bundle](bundle.md) directory that includes all of the files required for launching an application as a container. The bundle contains an OCI [configuration file](config.md) where the builder can specify host-independent details such as [which executable to launch](config.md#process) and host-specific settings such as [mount](config.md#mounts) locations, [hook](config.md#posix-platform-hooks) paths, Linux [namespaces](config-linux.md#namespaces) and [cgroups](config-linux.md#control-groups). Because the configuration includes host-specific settings, application bundle directories copied between two hosts may require configuration adjustments. ### Hook Developers [Hook](config.md#posix-platform-hooks) developers can extend the functionality of an OCI-compliant runtime by hooking into a container's lifecycle with an external application. Example use cases include sophisticated network configuration, volume garbage collection, etc. ### Runtime Developers Runtime developers can build runtime implementations that run OCI-compliant bundles and container configuration, containing low-level OS and host-specific details, on a particular platform. ## Contributing Development happens on GitHub for the spec. Issues are used for bugs and actionable items and longer discussions can happen on the [mailing list](#mailing-list). The specification and code is licensed under the Apache 2.0 license found in the [LICENSE](./LICENSE) file. ### Discuss your design The project welcomes submissions, but please let everyone know what you are working on. Before undertaking a nontrivial change to this specification, send mail to the [mailing list](#mailing-list) to discuss what you plan to do. This gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits. It also guarantees that the design is sound before code is written; a GitHub pull-request is not the place for high-level discussions. Typos and grammatical errors can go straight to a pull-request. When in doubt, start on the [mailing-list](#mailing-list). ### Meetings Please see the [OCI org repository README](https://github.com/opencontainers/org#meetings) for the most up-to-date information on OCI contributor and maintainer meeting schedules. You can also find links to meeting agendas and minutes for all prior meetings. ### Mailing List You can subscribe and join the mailing list on [Google Groups][dev-list]. ### Chat OCI discussion happens in the following chat rooms, which are all bridged together: - #general channel on [OCI Slack](https://opencontainers.org/community/overview/#chat) - #opencontainers:matrix.org ### Git commit #### Sign your work The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from http://developercertificate.org): ``` Developer Certificate of Origin Version 1.1 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 660 York Street, Suite 102, San Francisco, CA 94110 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Read more on [How to Write a Git Commit Message][how-to-git-commit] or the Discussion section of [git-commit(1)][git-commit.1]. 1. Separate the subject from body with a blank line 2. Limit the subject line to 50 characters 3. Capitalize the subject line 4. Do not end the subject line with a period 5. Use the imperative mood in the subject line 6. Wrap the body at 72 characters 7. Use the body to explain what and why vs. how * If there was important/useful/essential conversation or information, copy or include a reference 8. When possible, one keyword to scope the change in the subject (i.e. "README: ...", "runtime: ...")

This includes the process to run, environment variables to inject, sandboxing features to use, etc. The canonical schema is defined in this document, but there is a JSON Schema in [`schema/config-schema.json`](schema/config-schema.json) and Go bindings in [`specs-go/config.go`](specs-go/config.go). [Platform](spec.md#platforms)-specific configuration schema are defined in the [platform-specific documents](#platform-specific-configuration) linked below. For properties that are only defined for some [platforms](spec.md#platforms), the Go property has a `platform` tag listing those protocols (e.g. `platform:"linux,solaris"`). Below is a detailed description of each field defined in the configuration format and valid values are specified. Platform-specific fields are identified as such. For all platform-specific configuration values, the scope defined below in the [Platform-specific configuration](#platform-specific-configuration) section applies. ## Specification version * **`ociVersion`** (string, REQUIRED) MUST be in [SemVer v2.0.0][semver-v2.0.0] format and specifies the version of the Open Container Initiative Runtime Specification with which the bundle complies. The Open Container Initiative Runtime Specification follows semantic versioning and retains forward and backward compatibility within major versions. For example, if a configuration is compliant with version 1.1 of this specification, it is compatible with all runtimes that support any 1.1 or later release of this specification, but is not compatible with a runtime that supports 1.0 and not 1.1. ### Example ```json "ociVersion": "0.1.0" ``` ## Root **`root`** (object, OPTIONAL) specifies the container's root filesystem. On Windows, for Windows Server Containers, this field is REQUIRED. For [Hyper-V Containers](config-windows.md#hyperv), this field MUST NOT be set. On all other platforms, this field is REQUIRED. * **`path`** (string, REQUIRED) Specifies the path to the root filesystem for the container. * On Windows, `path` MUST be a [volume GUID path][naming-a-volume]. * On POSIX platforms, `path` is either an absolute path or a relative path to the bundle. For example, with a bundle at `/to/bundle` and a root filesystem at `/to/bundle/rootfs`, the `path` value can be either `/to/bundle/rootfs` or `rootfs`. The value SHOULD be the conventional `rootfs`. A directory MUST exist at the path declared by the field. * **`readonly`** (bool, OPTIONAL) If true then the root filesystem MUST be read-only inside the container, defaults to false. * On Windows, this field MUST be omitted or false. ### Example (POSIX platforms) ```json "root": { "path": "rootfs", "readonly": true } ``` ### Example (Windows) ```json "root": { "path": "\\\\?\\Volume{ec84d99e-3f02-11e7-ac6c-00155d7682cf}\\" } ``` ## Mounts **`mounts`** (array of objects, OPTIONAL) specifies additional mounts beyond [`root`](#root). The runtime MUST mount entries in the listed order. For Linux, the parameters are as documented in [mount(2)][mount.2] system call man page. For Solaris, the mount entry corresponds to the 'fs' resource in the [zonecfg(1M)][zonecfg.1m] man page. * **`destination`** (string, REQUIRED) Destination of mount point: path inside container. * Linux: This value SHOULD be an absolute path. For compatibility with old tools and configurations, it MAY be a relative path, in which case it MUST be interpreted as relative to "/". Relative paths are **deprecated**. * Windows: This value MUST be an absolute path. One mount destination MUST NOT be nested within another mount (e.g., c:\\foo and c:\\foo\\bar). * Solaris: This value MUST be an absolute path. Corresponds to "dir" of the fs resource in [zonecfg(1M)][zonecfg.1m]. * For all other platforms: This value MUST be an absolute path. * **`source`** (string, OPTIONAL) A device name, but can also be a file or directory name for bind mounts or a dummy. Path values for bind mounts are either absolute or relative to the bundle. A mount is a bind mount if it has either `bind` or `rbind` in the options. * Windows: a local directory on the filesystem of the container host. UNC paths and mapped drives are not supported. * Solaris: corresponds to "special" of the fs resource in [zonecfg(1M)][zonecfg.1m]. * **`options`** (array of strings, OPTIONAL) Mount options of the filesystem to be used. * Linux: See [Linux mount options](#configLinuxMountOptions) below. * Solaris: corresponds to "options" of the fs resource in [zonecfg(1M)][zonecfg.1m]. * Windows: runtimes MUST support `ro`, mounting the filesystem read-only when `ro` is given. ### Linux mount options Runtimes MUST/SHOULD/MAY implement the following option strings for Linux: Option name | Requirement | Description ------------------|-------------|----------------------------------------------------- `async` | MUST | [^1] `atime` | MUST | [^1] `bind` | MUST | Bind mount [^2] `defaults` | MUST | [^1] `dev` | MUST | [^1] `diratime` | MUST | [^1] `dirsync` | MUST | [^1] `exec` | MUST | [^1] `iversion` | MUST | [^1] `lazytime` | MUST | [^1] `loud` | MUST | [^1] `mand` | MAY | [^1] (Deprecated in kernel 5.15, util-linux 2.38) `noatime` | MUST | [^1] `nodev` | MUST | [^1] `nodiratime` | MUST | [^1] `noexec` | MUST | [^1] `noiversion` | MUST | [^1] `nolazytime` | MUST | [^1] `nomand` | MAY | [^1] `norelatime` | MUST | [^1] `nostrictatime` | MUST | [^1] `nosuid` | MUST | [^1] `nosymfollow` | SHOULD | [^1] (Introduced in kernel 5.10, util-linux 2.38) `private` | MUST | Bind mount propagation [^2] `ratime` | SHOULD | Recursive `atime` [^3] `rbind` | MUST | Recursive bind mount [^2] `rdev` | SHOULD | Recursive `dev` [^3] `rdiratime` | SHOULD | Recursive `diratime` [^3] `relatime` | MUST | [^1] `remount` | MUST | [^1] `rexec` | SHOULD | Recursive `dev` [^3] `rnoatime` | SHOULD | Recursive `noatime` [^3] `rnodiratime` | SHOULD | Recursive `nodiratime` [^3] `rnoexec` | SHOULD | Recursive `noexec` [^3] `rnorelatime` | SHOULD | Recursive `norelatime` [^3] `rnostrictatime` | SHOULD | Recursive `nostrictatime` [^3] `rnosuid` | SHOULD | Recursive `nosuid` [^3] `rnosymfollow` | SHOULD | Recursive `nosymfollow` [^3] `ro` | MUST | [^1] `rprivate` | MUST | Bind mount propagation [^2] `rrelatime ` | SHOULD | Recursive `relatime` [^3] `rro` | SHOULD | Recursive `ro` [^3] `rrw` | SHOULD | Recursive `rw` [^3] `rshared` | MUST | Bind mount propagation [^2] `rslave` | MUST | Bind mount propagation [^2] `rstrictatime` | SHOULD | Recursive `strictatime` [^3] `rsuid` | SHOULD | Recursive `suid` [^3] `rsymfollow` | SHOULD | Recursive `symfollow` [^3] `runbindable` | MUST | Bind mount propagation [^2] `rw` | MUST | [^1] `shared` | MUST | [^1] `silent` | MUST | [^1] `slave` | MUST | Bind mount propagation [^2] `strictatime` | MUST | [^1] `suid` | MUST | [^1] `symfollow` | SHOULD | Opposite of `nosymfollow` `sync` | MUST | [^1] `tmpcopyup` | MAY | copy up the contents to a tmpfs `unbindable` | MUST | Bind mount propagation [^2] `idmap` | SHOULD | Indicates that the mount MUST have an idmapping applied. This option SHOULD NOT be passed to the underlying [`mount(2)`][mount.2] call. If `uidMappings` or `gidMappings` are specified for the mount, the runtime MUST use those values for the mount's mapping. If they are not specified, the runtime MAY use the container's user namespace mapping, otherwise an [error MUST be returned](runtime.md#errors). If there are no `uidMappings` and `gidMappings` specified and the container isn't using user namespaces, an [error MUST be returned](runtime.md#errors). This SHOULD be implemented using [`mount_setattr(MOUNT_ATTR_IDMAP)`][mount_setattr.2], available since Linux 5.12. `ridmap` | SHOULD | Indicates that the mount MUST have an idmapping applied, and the mapping is applied recursively [^3]. This option SHOULD NOT be passed to the underlying [`mount(2)`][mount.2] call. If `uidMappings` or `gidMappings` are specified for the mount, the runtime MUST use those values for the mount's mapping. If they are not specified, the runtime MAY use the container's user namespace mapping, otherwise an [error MUST be returned](runtime.md#errors). If there are no `uidMappings` and `gidMappings` specified and the container isn't using user namespaces, an [error MUST be returned](runtime.md#errors). This SHOULD be implemented using [`mount_setattr(MOUNT_ATTR_IDMAP)`][mount_setattr.2], available since Linux 5.12. [^1]: Corresponds to [`mount(8)` (filesystem-independent)][mount.8-filesystem-independent]. [^2]: Corresponds to [bind mounts and shared subtrees][mount-bind]. [^3]: These `AT_RECURSIVE` options need kernel 5.12 or later. See [`mount_setattr(2)`][mount_setattr.2] The "MUST" options correspond to [`mount(8)`][mount.8]. Runtimes MAY also implement custom option strings that are not listed in the table above. If a custom option string is already recognized by [`mount(8)`][mount.8], the runtime SHOULD follow the behavior of [`mount(8)`][mount.8]. Runtimes SHOULD treat unknown options as [filesystem-specific ones][mount.8-filesystem-specific]) and pass those as a comma-separated string to the fifth (`const void *data`) argument of [`mount(2)`][mount.2]. ### Example (Windows) ```json "mounts": [ { "destination": "C:\\folder-inside-container", "source": "C:\\folder-on-host", "options": ["ro"] } ] ``` ### POSIX-platform Mounts For POSIX platforms the `mounts` structure has the following fields: * **`type`** (string, OPTIONAL) The type of the filesystem to be mounted. * Linux: filesystem types supported by the kernel as listed in */proc/filesystems* (e.g., "minix", "ext2", "ext3", "jfs", "xfs", "reiserfs", "msdos", "proc", "nfs", "iso9660"). For bind mounts (when `options` include either `bind` or `rbind`), the type is a dummy, often "none" (not listed in */proc/filesystems*). * Solaris: corresponds to "type" of the fs resource in [zonecfg(1M)][zonecfg.1m]. * **`uidMappings`** (array of type LinuxIDMapping, OPTIONAL) The mapping to convert UIDs from the source file system to the destination mount point. This SHOULD be implemented using [`mount_setattr(MOUNT_ATTR_IDMAP)`][mount_setattr.2], available since Linux 5.12. If specified, the `options` field of the `mounts` structure SHOULD contain either `idmap` or `ridmap` to specify whether the mapping should be applied recursively for `rbind` mounts, as well as to ensure that older runtimes will not silently ignore this field. The format is the same as [user namespace mappings](config-linux.md#user-namespace-mappings). If specified, it MUST be specified along with `gidMappings`. * **`gidMappings`** (array of type LinuxIDMapping, OPTIONAL) The mapping to convert GIDs from the source file system to the destination mount point. This SHOULD be implemented using [`mount_setattr(MOUNT_ATTR_IDMAP)`][mount_setattr.2], available since Linux 5.12. If specified, the `options` field of the `mounts` structure SHOULD contain either `idmap` or `ridmap` to specify whether the mapping should be applied recursively for `rbind` mounts, as well as to ensure that older runtimes will not silently ignore this field. For more details see `uidMappings`. If specified, it MUST be specified along with `uidMappings`. ### Example (Linux) ```json "mounts": [ { "destination": "/tmp", "type": "tmpfs", "source": "tmpfs", "options": ["nosuid","strictatime","mode=755","size=65536k"] }, { "destination": "/data", "type": "none", "source": "/volumes/testing", "options": ["rbind","rw"] } ] ``` ### Example (Solaris) ```json "mounts": [ { "destination": "/opt/local", "type": "lofs", "source": "/usr/local", "options": ["ro","nodevices"] }, { "destination": "/opt/sfw", "type": "lofs", "source": "/opt/sfw" } ] ``` ## Process **`process`** (object, OPTIONAL) specifies the container process. This property is REQUIRED when [`start`](runtime.md#start) is called. * **`terminal`** (bool, OPTIONAL) specifies whether a terminal is attached to the process, defaults to false. As an example, if set to true on Linux a pseudoterminal pair is allocated for the process and the pseudoterminal pty is duplicated on the process's [standard streams][stdin.3]. * **`consoleSize`** (object, OPTIONAL) specifies the console size in characters of the terminal. Runtimes MUST ignore `consoleSize` if `terminal` is `false` or unset. * **`height`** (uint, REQUIRED) * **`width`** (uint, REQUIRED) * **`cwd`** (string, REQUIRED) is the working directory that will be set for the executable. This value MUST be an absolute path. * **`env`** (array of strings, OPTIONAL) with the same semantics as [IEEE Std 1003.1-2008's `environ`][ieee-1003.1-2008-xbd-c8.1]. * **`args`** (array of strings, OPTIONAL) with similar semantics to [IEEE Std 1003.1-2008 `execvp`'s *argv*][ieee-1003.1-2008-functions-exec]. This specification extends the IEEE standard in that at least one entry is REQUIRED (non-Windows), and that entry is used with the same semantics as `execvp`'s *file*. This field is OPTIONAL on Windows, and `commandLine` is REQUIRED if this field is omitted. * **`commandLine`** (string, OPTIONAL) specifies the full command line to be executed on Windows. This is the preferred means of supplying the command line on Windows. If omitted, the runtime will fall back to escaping and concatenating fields from `args` before making the system call into Windows. ### POSIX process For systems that support POSIX rlimits (for example Linux and Solaris), the `process` object supports the following process-specific properties: * **`rlimits`** (array of objects, OPTIONAL) allows setting resource limits for the process. Each entry has the following structure: * **`type`** (string, REQUIRED) the platform resource being limited. * Linux: valid values are defined in the [`getrlimit(2)`][getrlimit.2] man page, such as `RLIMIT_MSGQUEUE`. * Solaris: valid values are defined in the [`getrlimit(3)`][getrlimit.3] man page, such as `RLIMIT_CORE`. The runtime MUST [generate an error](runtime.md#errors) for any values which cannot be mapped to a relevant kernel interface. For each entry in `rlimits`, a [`getrlimit(3)`][getrlimit.3] on `type` MUST succeed. For the following properties, `rlim` refers to the status returned by the `getrlimit(3)` call. * **`soft`** (uint64, REQUIRED) the value of the limit enforced for the corresponding resource. `rlim.rlim_cur` MUST match the configured value. * **`hard`** (uint64, REQUIRED) the ceiling for the soft limit that could be set by an unprivileged process. `rlim.rlim_max` MUST match the configured value. Only a privileged process (e.g. one with the `CAP_SYS_RESOURCE` capability) can raise a hard limit. If `rlimits` contains duplicated entries with same `type`, the runtime MUST [generate an error](runtime.md#errors). ### Linux Process For Linux-based systems, the `process` object supports the following process-specific properties. * **`apparmorProfile`** (string, OPTIONAL) specifies the name of the AppArmor profile for the process. For more information about AppArmor, see [AppArmor documentation][apparmor]. * **`capabilities`** (object, OPTIONAL) is an object containing arrays that specifies the sets of capabilities for the process. Valid values are defined in the [capabilities(7)][capabilities.7] man page, such as `CAP_CHOWN`. Any value which cannot be mapped to a relevant kernel interface, or cannot be granted otherwise MUST be [logged as a warning](runtime.md#warnings) by the runtime. Runtimes SHOULD NOT fail if the container configuration requests capabilities that cannot be granted, for example, if the runtime operates in a restricted environment with a limited set of capabilities. `capabilities` contains the following properties: * **`effective`** (array of strings, OPTIONAL) the `effective` field is an array of effective capabilities that are kept for the process. * **`bounding`** (array of strings, OPTIONAL) the `bounding` field is an array of bounding capabilities that are kept for the process. * **`inheritable`** (array of strings, OPTIONAL) the `inheritable` field is an array of inheritable capabilities that are kept for the process. * **`permitted`** (array of strings, OPTIONAL) the `permitted` field is an array of permitted capabilities that are kept for the process. * **`ambient`** (array of strings, OPTIONAL) the `ambient` field is an array of ambient capabilities that are kept for the process. * **`noNewPrivileges`** (bool, OPTIONAL) setting `noNewPrivileges` to true prevents the process from gaining additional privileges. As an example, the [`no_new_privs`][no-new-privs] article in the kernel documentation has information on how this is achieved using a `prctl` system call on Linux. * **`oomScoreAdj`** *(int, OPTIONAL)* adjusts the oom-killer score in `[pid]/oom_score_adj` for the process's `[pid]` in a [proc pseudo-filesystem][proc_2]. If `oomScoreAdj` is set, the runtime MUST set `oom_score_adj` to the given value. If `oomScoreAdj` is not set, the runtime MUST NOT change the value of `oom_score_adj`. This is a per-process setting, where as [`disableOOMKiller`](config-linux.md#memory) is scoped for a memory cgroup. For more information on how these two settings work together, see [the memory cgroup documentation section 10. OOM Contol][cgroup-v1-memory_2]. * **`scheduler`** (object, OPTIONAL) is an object describing the scheduler properties for the process. The `scheduler` contains the following properties: * **`policy`** (string, REQUIRED) represents the scheduling policy. A valid list of values is: * `SCHED_OTHER` * `SCHED_FIFO` * `SCHED_RR` * `SCHED_BATCH` * `SCHED_ISO` * `SCHED_IDLE` * `SCHED_DEADLINE` * **`nice`** (int32, OPTIONAL) is the nice value for the process, affecting its priority. A lower nice value corresponds to a higher priority. If not set, the runtime must use the value 0. * **`priority`** (int32, OPTIONAL) represents the static priority of the process, used by real-time policies like SCHED_FIFO and SCHED_RR. If not set, the runtime must use the value 0. * **`flags`** (array of strings, OPTIONAL) is an array of strings representing scheduling flags. A valid list of values is: * `SCHED_FLAG_RESET_ON_FORK` * `SCHED_FLAG_RECLAIM` * `SCHED_FLAG_DL_OVERRUN` * `SCHED_FLAG_KEEP_POLICY` * `SCHED_FLAG_KEEP_PARAMS` * `SCHED_FLAG_UTIL_CLAMP_MIN` * `SCHED_FLAG_UTIL_CLAMP_MAX` * **`runtime`** (uint64, OPTIONAL) represents the amount of time in nanoseconds during which the process is allowed to run in a given period, used by the deadline scheduler. If not set, the runtime must use the value 0. * **`deadline`** (uint64, OPTIONAL) represents the absolute deadline for the process to complete its execution, used by the deadline scheduler. If not set, the runtime must use the value 0. * **`period`** (uint64, OPTIONAL) represents the length of the period in nanoseconds used for determining the process runtime, used by the deadline scheduler. If not set, the runtime must use the value 0. * **`selinuxLabel`** (string, OPTIONAL) specifies the SELinux label for the process. For more information about SELinux, see [SELinux documentation][selinux]. * **`ioPriority`** (object, OPTIONAL) configures the I/O priority settings for the container's processes within the process group. The I/O priority settings will be automatically applied to the entire process group, affecting all processes within the container. The following properties are available: * **`class`** (string, REQUIRED) specifies the I/O scheduling class. Possible values are `IOPRIO_CLASS_RT`, `IOPRIO_CLASS_BE`, and `IOPRIO_CLASS_IDLE`. * **`priority`** (int, REQUIRED) specifies the priority level within the class. The value should be an integer ranging from 0 (highest) to 7 (lowest). ### User The user for the process is a platform-specific structure that allows specific control over which user the process runs as. #### POSIX-platform User For POSIX platforms the `user` structure has the following fields: * **`uid`** (int, REQUIRED) specifies the user ID in the [container namespace](glossary.md#container-namespace). * **`gid`** (int, REQUIRED) specifies the group ID in the [container namespace](glossary.md#container-namespace). * **`umask`** (int, OPTIONAL) specifies the [umask][umask_2] of the user. If unspecified, the umask should not be changed from the calling process' umask. * **`additionalGids`** (array of ints, OPTIONAL) specifies additional group IDs in the [container namespace](glossary.md#container-namespace) to be added to the process. _Note: symbolic name for uid and gid, such as uname and gname respectively, are left to upper levels to derive (i.e. `/etc/passwd` parsing, NSS, etc)_ ### Example (Linux) ```json "process": { "terminal": true, "consoleSize": { "height": 25, "width": 80 }, "user": { "uid": 1, "gid": 1, "umask": 63, "additionalGids": [5, 6] }, "env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "TERM=xterm" ], "cwd": "/root", "args": [ "sh" ], "apparmorProfile": "acme_secure_profile", "selinuxLabel": "system_u:system_r:svirt_lxc_net_t:s0:c124,c675", "ioPriority": { "class": "IOPRIO_CLASS_IDLE", "priority": 4 }, "noNewPrivileges": true, "capabilities": { "bounding": [ "CAP_AUDIT_WRITE", "CAP_KILL", "CAP_NET_BIND_SERVICE" ], "permitted": [ "CAP_AUDIT_WRITE", "CAP_KILL", "CAP_NET_BIND_SERVICE" ], "inheritable": [ "CAP_AUDIT_WRITE", "CAP_KILL", "CAP_NET_BIND_SERVICE" ], "effective": [ "CAP_AUDIT_WRITE", "CAP_KILL" ], "ambient": [ "CAP_NET_BIND_SERVICE" ] }, "rlimits": [ { "type": "RLIMIT_NOFILE", "hard": 1024, "soft": 1024 } ] } ``` ### Example (Solaris) ```json "process": { "terminal": true, "consoleSize": { "height": 25, "width": 80 }, "user": { "uid": 1, "gid": 1, "umask": 7, "additionalGids": [2, 8] }, "env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "TERM=xterm" ], "cwd": "/root", "args": [ "/usr/bin/bash" ] } ``` #### Windows User For Windows based systems the user structure has the following fields: * **`username`** (string, OPTIONAL) specifies the user name for the process. ### Example (Windows) ```json "process": { "terminal": true, "user": { "username": "containeradministrator" }, "env": [ "VARIABLE=1" ], "cwd": "c:\\foo", "args": [ "someapp.exe", ] } ``` ## Hostname * **`hostname`** (string, OPTIONAL) specifies the container's hostname as seen by processes running inside the container. On Linux, for example, this will change the hostname in the [container](glossary.md#container-namespace) [UTS namespace][uts-namespace.7]. Depending on your [namespace configuration](config-linux.md#namespaces), the container UTS namespace may be the [runtime](glossary.md#runtime-namespace) [UTS namespace][uts-namespace.7]. ### Example ```json "hostname": "mrsdalloway" ``` ## Domainname * **`domainname`** (string, OPTIONAL) specifies the container's domainname as seen by processes running inside the container. On Linux, for example, this will change the domainname in the [container](glossary.md#container-namespace) [UTS namespace][uts-namespace.7]. Depending on your [namespace configuration](config-linux.md#namespaces), the container UTS namespace may be the [runtime](glossary.md#runtime-namespace) [UTS namespace][uts-namespace.7]. ### Example ```json "domainname": "foobarbaz.test" ``` ## Platform-specific configuration * **`linux`** (object, OPTIONAL) [Linux-specific configuration](config-linux.md). This MAY be set if the target platform of this spec is `linux`. * **`windows`** (object, OPTIONAL) [Windows-specific configuration](config-windows.md).

This MAY be set if the target platform of this spec is `zos`. ### Example (Linux) ```json { "linux": { "namespaces": [ { "type": "pid" } ] } } ``` ## POSIX-platform Hooks For POSIX platforms, the configuration structure supports `hooks` for configuring custom actions related to the [lifecycle](runtime.md#lifecycle) of the container. * **`hooks`** (object, OPTIONAL) MAY contain any of the following properties: * **`prestart`** (array of objects, OPTIONAL, **DEPRECATED**) is an array of [`prestart` hooks](#prestart). * Entries in the array contain the following properties: * **`path`** (string, REQUIRED) with similar semantics to [IEEE Std 1003.1-2008 `execv`'s *path*][ieee-1003.1-2008-functions-exec]. This specification extends the IEEE standard in that **`path`** MUST be absolute. * **`args`** (array of strings, OPTIONAL) with the same semantics as [IEEE Std 1003.1-2008 `execv`'s *argv*][ieee-1003.1-2008-functions-exec]. * **`env`** (array of strings, OPTIONAL) with the same semantics as [IEEE Std 1003.1-2008's `environ`][ieee-1003.1-2008-xbd-c8.1]. * **`timeout`** (int, OPTIONAL) is the number of seconds before aborting the hook. If set, `timeout` MUST be greater than zero. * The value of `path` MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). * The `prestart` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). * **`createRuntime`** (array of objects, OPTIONAL) is an array of [`createRuntime` hooks](#createRuntime-hooks). * Entries in the array contain the following properties (the entries are identical to the entries in the deprecated `prestart` hooks): * **`path`** (string, REQUIRED) with similar semantics to [IEEE Std 1003.1-2008 `execv`'s *path*][ieee-1003.1-2008-functions-exec]. This specification extends the IEEE standard in that **`path`** MUST be absolute. * **`args`** (array of strings, OPTIONAL) with the same semantics as [IEEE Std 1003.1-2008 `execv`'s *argv*][ieee-1003.1-2008-functions-exec]. * **`env`** (array of strings, OPTIONAL) with the same semantics as [IEEE Std 1003.1-2008's `environ`][ieee-1003.1-2008-xbd-c8.1]. * **`timeout`** (int, OPTIONAL) is the number of seconds before aborting the hook. If set, `timeout` MUST be greater than zero. * The value of `path` MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). * The `createRuntime` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). * **`createContainer`** (array of objects, OPTIONAL) is an array of [`createContainer` hooks](#createContainer-hooks). * Entries in the array have the same schema as `createRuntime` entries. * The value of `path` MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). * The `createContainer` hooks MUST be executed in the [container namespace](glossary.md#container-namespace). * **`startContainer`** (array of objects, OPTIONAL) is an array of [`startContainer` hooks](#startContainer-hooks). * Entries in the array have the same schema as `createRuntime` entries. * The value of `path` MUST resolve in the [container namespace](glossary.md#container-namespace). * The `startContainer` hooks MUST be executed in the [container namespace](glossary.md#container-namespace). * **`poststart`** (array of objects, OPTIONAL) is an array of [`poststart` hooks](#poststart). * Entries in the array have the same schema as `createRuntime` entries. * The value of `path` MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). * The `poststart` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). * **`poststop`** (array of objects, OPTIONAL) is an array of [`poststop` hooks](#poststop). * Entries in the array have the same schema as `createRuntime` entries. * The value of `path` MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). * The `poststop` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). Hooks allow users to specify programs to run before or after various lifecycle events. Hooks MUST be called in the listed order. The [state](runtime.md#state) of the container MUST be passed to hooks over stdin so that they may do work appropriate to the current state of the container. ### Prestart The `prestart` hooks MUST be called as part of the [`create`](runtime.md#create) operation after the runtime environment has been created (according to the configuration in config.json) but before the `pivot_root` or any equivalent operation has been executed. On Linux, for example, they are called after the container namespaces are created, so they provide an opportunity to customize the container (e.g. the network namespace could be specified in this hook). The `prestart` hooks MUST be called before the `createRuntime` hooks. Note: `prestart` hooks were deprecated in favor of `createRuntime`, `createContainer` and `startContainer` hooks, which allow more granular hook control during the create and start phase. The `prestart` hooks' path MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). The `prestart` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). ### CreateRuntime Hooks The `createRuntime` hooks MUST be called as part of the [`create`](runtime.md#create) operation after the runtime environment has been created (according to the configuration in config.json) but before the `pivot_root` or any equivalent operation has been executed. The `createRuntime` hooks' path MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). The `createRuntime` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). On Linux, for example, they are called after the container namespaces are created, so they provide an opportunity to customize the container (e.g. the network namespace could be specified in this hook). The definition of `createRuntime` hooks is currently underspecified and hooks authors, should only expect from the runtime that the mount namespace have been created and the mount operations performed. Other operations such as cgroups and SELinux/AppArmor labels might not have been performed by the runtime. ### CreateContainer Hooks The `createContainer` hooks MUST be called as part of the [`create`](runtime.md#create) operation after the runtime environment has been created (according to the configuration in config.json) but before the `pivot_root` or any equivalent operation has been executed. The `createContainer` hooks MUST be called after the `createRuntime` hooks. The `createContainer` hooks' path MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). The `createContainer` hooks MUST be executed in the [container namespace](glossary.md#container-namespace). For example, on Linux this would happen before the `pivot_root` operation is executed but after the mount namespace was created and setup. The definition of `createContainer` hooks is currently underspecified and hooks authors, should only expect from the runtime that the mount namespace and different mounts will be setup. Other operations such as cgroups and SELinux/AppArmor labels might not have been performed by the runtime. ### StartContainer Hooks The `startContainer` hooks MUST be called [before the user-specified process is executed](runtime.md#lifecycle) as part of the [`start`](runtime.md#start) operation. This hook can be used to execute some operations in the container, for example running the `ldconfig` binary on linux before the container process is spawned. The `startContainer` hooks' path MUST resolve in the [container namespace](glossary.md#container-namespace). The `startContainer` hooks MUST be executed in the [container namespace](glossary.md#container-namespace). ### Poststart The `poststart` hooks MUST be called [after the user-specified process is executed](runtime.md#lifecycle) but before the [`start`](runtime.md#start) operation returns. For example, this hook can notify the user that the container process is spawned. The `poststart` hooks' path MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). The `poststart` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). ### Poststop The `poststop` hooks MUST be called [after the container is deleted](runtime.md#lifecycle) but before the [`delete`](runtime.md#delete) operation returns. Cleanup or debugging functions are examples of such a hook. The `poststop` hooks' path MUST resolve in the [runtime namespace](glossary.md#runtime-namespace). The `poststop` hooks MUST be executed in the [runtime namespace](glossary.md#runtime-namespace). ### Summary See the below table for a summary of hooks and when they are called: | Name | Namespace | When | | ----------------------- | --------- | -----------------------------------------------------------------------------------------------------------------------------------| | `prestart` (Deprecated) | runtime | After the start operation is called but before the user-specified program command is executed. | | `createRuntime` | runtime | During the create operation, after the runtime environment has been created and before the pivot root or any equivalent operation. | | `createContainer` | container | During the create operation, after the runtime environment has been created and before the pivot root or any equivalent operation. | | `startContainer` | container | After the start operation is called but before the user-specified program command is executed. | | `poststart` | runtime | After the user-specified process is executed but before the start operation returns. | | `poststop` | runtime | After the container is deleted but before the delete operation returns. | ### Example ```json "hooks": { "prestart": [ { "path": "/usr/bin/fix-mounts", "args": ["fix-mounts", "arg1", "arg2"], "env": [ "key1=value1"] }, { "path": "/usr/bin/setup-network" } ], "createRuntime": [ { "path": "/usr/bin/fix-mounts", "args": ["fix-mounts", "arg1", "arg2"], "env": [ "key1=value1"] }, { "path": "/usr/bin/setup-network" } ], "createContainer": [ { "path": "/usr/bin/mount-hook", "args": ["-mount", "arg1", "arg2"], "env": [ "key1=value1"] } ], "startContainer": [ { "path": "/usr/bin/refresh-ldcache" } ], "poststart": [ { "path": "/usr/bin/notify-start", "timeout": 5 } ], "poststop": [ { "path": "/usr/sbin/cleanup.sh", "args": ["cleanup.sh", "-f"] } ] } ``` ## Annotations **`annotations`** (object, OPTIONAL) contains arbitrary metadata for the container.

Project's maintainers (listed in the repository's MAINTAINERS file and sometimes referred to as "the TDC", [§5.e][charter]) with: > Creating, maintaining and enforcing governance guidelines for the TDC, approved by the maintainers, and which shall be posted visibly for the TDC. This section describes generic rules and procedures for fulfilling that mandate. ## Proposing a motion A maintainer SHOULD propose a motion on the dev@opencontainers.org mailing list (except [security issues](#security-issues)) with another maintainer as a co-sponsor. ## Voting Voting on a proposed motion SHOULD happen on the dev@opencontainers.org mailing list (except [security issues](#security-issues)) with maintainers posting LGTM or REJECT. Maintainers MAY also explicitly not vote by posting ABSTAIN (which is useful to revert a previous vote). Maintainers MAY post multiple times (e.g. as they revise their position based on feedback), but only their final post counts in the tally. A proposed motion is adopted if two-thirds of votes cast, a quorum having voted, are in favor of the release. Voting SHOULD remain open for a week to collect feedback from the wider community and allow the maintainers to digest the proposed motion. Under exceptional conditions (e.g. non-major security fix releases) proposals which reach quorum with unanimous support MAY be adopted earlier. A maintainer MAY choose to reply with REJECT. A maintainer posting a REJECT MUST include a list of concerns or links to written documentation for those concerns (e.g. GitHub issues or mailing-list threads). The maintainers SHOULD try to resolve the concerns and wait for the rejecting maintainer to change their opinion to LGTM. However, a motion MAY be adopted with REJECTs, as outlined in the previous paragraphs. ## Quorum A quorum is established when at least two-thirds of maintainers have voted. For projects that are not specifications, a [motion to release](#release-approval) MAY be adopted if the tally is at least three LGTMs and no REJECTs, even if three votes does not meet the usual two-thirds quorum. ## Security issues Motions with sensitive security implications MUST be proposed on the security@opencontainers.org mailing list instead of dev@opencontainers.org, but should otherwise follow the standard [proposal](#proposing-a-motion) process. The security@opencontainers.org mailing list includes all members of the TOB. The TOB will contact the project maintainers and provide a channel for discussing and voting on the motion, but voting will otherwise follow the standard [voting](#voting) and [quorum](#quorum) rules. The TOB and project maintainers will work together to notify affected parties before making an adopted motion public. ## Amendments The [project governance](#project-governance) rules and procedures MAY be amended or replaced using the procedures themselves. The MAINTAINERS of this project governance document is the total set of MAINTAINERS from all Open Containers projects (runC, runtime-spec, and image-spec). ## Subject templates Maintainers are busy and get lots of email. To make project proposals recognizable, proposed motions SHOULD use the following subject templates. ### Proposing a motion > [{project} VOTE]: {motion description} (closes {end of voting window}) For example: > [runtime-spec VOTE]: Tag 0647920 as 1.0.0-rc (closes 2016-06-03 20:00 UTC) ### Tallying results After voting closes, a maintainer SHOULD post a tally to the motion thread with a subject template like: > [{project} {status}]: {motion description} (+{LGTMs} -{REJECTs} #{ABSTAINs}) Where `{status}` is either `adopted` or `rejected`. For example: > [runtime-spec adopted]: Tag 0647920 as 1.0.0-rc (+6 -0 #3) [charter]: https://github.com/opencontainers/tob/blob/main/CHARTER.md crun-1.16.1/libocispec/runtime-spec/.gitattributes0000664000000000000000000000010613677106243020367 0ustar0000000000000000# https://tools.ietf.org/html/rfc5545#section-3.1 *.ics text eol=crlf crun-1.16.1/libocispec/runtime-spec/.gitignore0000664000000000000000000000004213677106243017463 0ustar0000000000000000output schema/validate version.md crun-1.16.1/libocispec/runtime-spec/.mailmap0000664000000000000000000000220513677106243017117 0ustar0000000000000000Aleksa Sarai Alexander Morozov Amit Saha Antonio Murdaca Brandon Philips Brandon Philips ChengTiesheng Daniel, Dao Quang Minh Doug Davis James O.

Irrelevant to the availability of SELinux on the host operating system. * **`enabled`** (bool, OPTIONAL) represents whether the runtime supports SELinux. ### Example ```json "selinux": { "enabled": true } ``` ## Intel RDT **`intelRdt`** (object, OPTIONAL) represents the runtime's implementation status of Intel RDT. Irrelevant to the availability of Intel RDT on the host operating system. * **`enabled`** (bool, OPTIONAL) represents whether the runtime supports Intel RDT. ### Example ```json "intelRdt": { "enabled": true } ``` ## MountExtensions **`mountExtensions`** (object, OPTIONAL) represents whether the runtime supports certain mount features, irrespective of the availability of the features on the host operating system. * **`idmap`** (object, OPTIONAL) represents whether the runtime supports idmap mounts using the `uidMappings` and `gidMappings` properties of the mount. * **`enabled`** (bool, OPTIONAL) represents whether the runtime parses and attempts to use the `uidMappings` and `gidMappings` properties of mounts if provided. Note that it is possible for runtimes to have partial implementations of id-mapped mounts support (such as only allowing mounts which have mappings matching the container's user namespace, or only allowing the id-mapped bind-mounts). In such cases, runtimes MUST still set this value to `true`, to indicate that the runtime recognises the `uidMappings` and `gidMappings` properties. ### Example ```json "mountExtensions": { "idmap":{ "enabled": true } } ``` crun-1.16.1/libocispec/runtime-spec/bundle.md0000664000000000000000000000274613677106243017303 0ustar0000000000000000# Filesystem Bundle ## Container Format This section defines a format for encoding a container as a *filesystem bundle* - a set of files organized in a certain way, and containing all the necessary data and metadata for any compliant runtime to perform all standard operations against it. See also [MacOS application bundles][macos_bundle] for a similar use of the term *bundle*. The definition of a bundle is only concerned with how a container, and its configuration data, are stored on a local filesystem so that it can be consumed by a compliant runtime. A Standard Container bundle contains all the information needed to load and run a container. This includes the following artifacts: 1. `config.json`: contains configuration data. This REQUIRED file MUST reside in the root of the bundle directory and MUST be named `config.json`. See [`config.json`](config.md) for more details. 2. container's root filesystem: the directory referenced by [`root.path`](config.md#root), if that property is set in `config.json`. When supplied, while these artifacts MUST all be present in a single directory on the local filesystem, that directory itself is not part of the bundle. In other words, a tar archive of a *bundle* will have these artifacts at the root of the archive, not nested within a top-level directory.

The runtime MAY supply them however it likes. Each entry has the following structure: * **`type`** *(string, REQUIRED)* - type of device: `c`, `b`, `u` or `p`. * **`path`** *(string, REQUIRED)* - full path to device inside container. If a file already exists at `path` that does not match the requested device, the runtime MUST generate an error. * **`major, minor`** *(int64, REQUIRED unless `type` is `p`)* - major, minor numbers for the device. * **`fileMode`** *(uint32, OPTIONAL)* - file mode for the device.

The property should consist of a comma-separated privilege set specification as described in [priv_str_to_set(3C)][priv-str-to-set.3c] man page for the respective release of Solaris. **`limitpriv`** *(string, OPTIONAL)* ### Example ```json "limitpriv": "default" ``` ## maxShmMemory The maximum amount of shared memory allowed for this application container. A scale (K, M, G, T) can be applied to the value for each of these numbers (for example, 1M is one megabyte). Mapped to `max-shm-memory` in [zonecfg(1M)][zonecfg.1m_2] man page. **`maxShmMemory`** *(string, OPTIONAL)* ### Example ```json "maxShmMemory": "512m" ``` ## cappedCPU Sets a limit on the amount of CPU time that can be used by a container. The unit used translates to the percentage of a single CPU that can be used by all user threads in a container, expressed as a fraction (for example, .75) or a mixed number (whole number and fraction, for example, 1.25). An ncpu value of 1 means 100% of a CPU, a value of 1.25 means 125%, .75 mean 75%, and so forth. When projects within a capped container have their own caps, the minimum value takes precedence. cappedCPU is mapped to `capped-cpu` in [zonecfg(1M)][zonecfg.1m_2] man page. * **`ncpus`** *(string, OPTIONAL)* ### Example ```json "cappedCPU": { "ncpus": "8" } ``` ## cappedMemory The physical and swap caps on the memory that can be used by this application container. A scale (K, M, G, T) can be applied to the value for each of these numbers (for example, 1M is one megabyte). cappedMemory is mapped to `capped-memory` in [zonecfg(1M)][zonecfg.1m_2] man page. * **`physical`** *(string, OPTIONAL)* * **`swap`** *(string, OPTIONAL)* ### Example ```json "cappedMemory": { "physical": "512m", "swap": "512m" } ``` ## Network ### Automatic Network (anet) anet is specified as an array that is used to set up networking for Solaris application containers. The anet resource represents the automatic creation of a network resource for an application container. The zones administration daemon, zoneadmd, is the primary process for managing the container's virtual platform. One of the daemon's responsibilities is creation and teardown of the networks for the container. For more information on the daemon see the [zoneadmd(1M)][zoneadmd.1m] man page. When such a container is started, a temporary VNIC(Virtual NIC) is automatically created for the container. The VNIC is deleted when the container is torn down. The following properties can be used to set up automatic networks. For additional information on properties, check the [zonecfg(1M)][zonecfg.1m_2] man page for the respective release of Solaris. * **`linkname`** *(string, OPTIONAL)* Specify a name for the automatically created VNIC datalink. * **`lowerLink`** *(string, OPTIONAL)* Specify the link over which the VNIC will be created. Mapped to `lower-link` in the [zonecfg(1M)][zonecfg.1m_2] man page. * **`allowedAddress`** *(string, OPTIONAL)* The set of IP addresses that the container can use might be constrained by specifying the `allowedAddress` property. If `allowedAddress` has not been specified, then they can use any IP address on the associated physical interface for the network resource. Otherwise, when `allowedAddress` is specified, the container cannot use IP addresses that are not in the `allowedAddress` list for the physical address. Mapped to `allowed-address` in the [zonecfg(1M)][zonecfg.1m_2] man page. * **`configureAllowedAddress`** *(string, OPTIONAL)* If `configureAllowedAddress` is set to true, the addresses specified by `allowedAddress` are automatically configured on the interface each time the container starts. When it is set to false, the `allowedAddress` will not be configured on container start. Mapped to `configure-allowed-address` in the [zonecfg(1M)][zonecfg.1m_2] man page. * **`defrouter`** *(string, OPTIONAL)* The value for the OPTIONAL default router. * **`macAddress`** *(string, OPTIONAL)* Set the VNIC's MAC addresses based on the specified value or keyword. If not a keyword, it is interpreted as a unicast MAC address. For a list of the supported keywords please refer to the [zonecfg(1M)][zonecfg.1m_2] man page of the respective Solaris release. Mapped to `mac-address` in the [zonecfg(1M)][zonecfg.1m_2] man page. * **`linkProtection`** *(string, OPTIONAL)* Enables one or more types of link protection using comma-separated values. See the protection property in dladm(8) for supported values in respective release of Solaris. Mapped to `link-protection` in the [zonecfg(1M)][zonecfg.1m_2] man page. #### Example ```json "anet": [ { "allowedAddress": "172.17.0.2/16", "configureAllowedAddress": "true", "defrouter": "172.17.0.1/16", "linkProtection": "mac-nospoof, ip-nospoof", "linkname": "net0", "lowerLink": "net2", "macAddress": "02:42:f8:52:c7:16" } ] ``` [priv-str-to-set.3c]: http://docs.oracle.com/cd/E86824_01/html/E54766/priv-str-to-set-3c.html [zoneadmd.1m]: http://docs.oracle.com/cd/E86824_01/html/E54764/zoneadmd-1m.html [zonecfg.1m_2]: http://docs.oracle.com/cd/E86824_01/html/E54764/zonecfg-1m.html crun-1.16.1/libocispec/runtime-spec/config-vm.md0000664000000000000000000000706613677106243017717 0ustar0000000000000000# Virtual-machine-specific Container Configuration This section describes the schema for the [virtual-machine-specific section](config.md#platform-specific-configuration) of the [container configuration](config.md). The virtual-machine container specification provides additional configuration for the hypervisor, kernel, and image. ## Hypervisor Object **`hypervisor`** (object, OPTIONAL) specifies details of the hypervisor that manages the container virtual machine. * **`path`** (string, REQUIRED) path to the hypervisor binary that manages the container virtual machine. This value MUST be an absolute path in the [runtime mount namespace](glossary.md#runtime-namespace). * **`parameters`** (array of strings, OPTIONAL) specifies an array of parameters to pass to the hypervisor. ### Example ```json "hypervisor": { "path": "/path/to/vmm", "parameters": ["opts1=foo", "opts2=bar"] } ``` ## Kernel Object **`kernel`** (object, REQUIRED) specifies details of the kernel to boot the container virtual machine with. * **`path`** (string, REQUIRED) path to the kernel used to boot the container virtual machine. This value MUST be an absolute path in the [runtime mount namespace](glossary.md#runtime-namespace). * **`parameters`** (array of strings, OPTIONAL) specifies an array of parameters to pass to the kernel. * **`initrd`** (string, OPTIONAL) path to an initial ramdisk to be used by the container virtual machine.

This value MUST be an absolute path in the [runtime mount namespace](glossary.md#runtime-namespace). * **`format`** (string, REQUIRED) format of the container virtual machine root image. Commonly supported formats are: * **`raw`** [raw disk image format][raw-image-format]. Unset values for `format` will default to that format. * **`qcow2`** [QEMU image format][qcow2-image-format]. * **`vdi`** [VirtualBox 1.1 compatible image format][vdi-image-format]. * **`vmdk`** [VMware compatible image format][vmdk-image-format]. * **`vhd`** [Virtual Hard Disk image format][vhd-image-format]. This image contains the root filesystem that the virtual machine **`kernel`** will boot into, not to be confused with the container root filesystem itself. The latter, as specified by **`path`** from the [Root Configuration](config.md#Root-Configuration) section, will be mounted inside the virtual machine at a location chosen by the virtual-machine-based runtime. ### Example ```json "image": { "path": "/path/to/vm/rootfs.img", "format": "raw" } ``` [raw-image-format]: https://en.wikipedia.org/wiki/IMG_(file_format) [qcow2-image-format]: https://git.qemu.org/?p=qemu.git;a=blob_plain;f=docs/interop/qcow2.txt;hb=HEAD [vdi-image-format]: https://forensicswiki.org/wiki/Virtual_Disk_Image_(VDI) [vmdk-image-format]: http://www.vmware.com/app/vmdk/?src=vmdk [vhd-image-format]: https://github.com/libyal/libvhdi/blob/master/documentation/Virtual%20Hard%20Disk%20(VHD)%20image%20format.asciidoc crun-1.16.1/libocispec/runtime-spec/config-windows.md0000664000000000000000000001670514265762063020771 0ustar0000000000000000# Windows-specific Container Configuration This document describes the schema for the [Windows-specific section](config.md#platform-specific-configuration) of the [container configuration](config.md). The Windows container specification uses APIs provided by the Windows Host Compute Service (HCS) to fulfill the spec. ## LayerFolders **`layerFolders`** (array of strings, REQUIRED) specifies a list of layer folders the container image relies on. The list is ordered from topmost layer to base layer with the last entry being the scratch. `layerFolders` MUST contain at least one entry. ### Example ```json "windows": { "layerFolders": [ "C:\\Layers\\layer2", "C:\\Layers\\layer1", "C:\\Layers\\layer-base", "C:\\scratch", ] } ``` ## Devices **`devices`** (array of objects, OPTIONAL) lists devices that MUST be available in the container. Each entry has the following structure: * **`id`** *(string, REQUIRED)* - specifies the device which the runtime MUST make available in the container. * **`idType`** *(string, REQUIRED)* - tells the runtime how to interpret `id`. Today, Windows only supports a value of `class`, which identifies `id` as a [device interface class GUID][interfaceGUID]. [interfaceGUID]: https://docs.microsoft.com/en-us/windows-hardware/drivers/install/overview-of-device-interface-classes ### Example ```json "windows": { "devices": [ { "id": "24E552D7-6523-47F7-A647-D3465BF1F5CA", "idType": "class" }, { "id": "5175d334-c371-4806-b3ba-71fd53c9258d", "idType": "class" } ] } ``` ## Resources You can configure a container's resource limits via the OPTIONAL `resources` field of the Windows configuration. ### Memory `memory` is an OPTIONAL configuration for the container's memory usage. The following parameters can be specified: * **`limit`** *(uint64, OPTIONAL)* - sets limit of memory usage in bytes. #### Example ```json "windows": { "resources": { "memory": { "limit": 2097152 } } } ``` ### CPU `cpu` is an OPTIONAL configuration for the container's CPU usage. The following parameters can be specified (mutually exclusive): * **`count`** *(uint64, OPTIONAL)* - specifies the number of CPUs available to the container. It represents the fraction of the configured processor `count` in a container in relation to the processors available in the host. The fraction ultimately determines the portion of processor cycles that the threads in a container can use during each scheduling interval, as the number of cycles per 10,000 cycles. * **`shares`** *(uint16, OPTIONAL)* - limits the share of processor time given to the container relative to other workloads on the processor. The processor `shares` (`weight` at the platform level) is a value between 0 and 10,000. * **`maximum`** *(uint16, OPTIONAL)* - determines the portion of processor cycles that the threads in a container can use during each scheduling interval, as the number of cycles per 10,000 cycles. Set processor `maximum` to a percentage times 100. Ref: https://docs.microsoft.com/en-us/virtualization/api/hcs/schemareference#Container_Processor #### Example ```json "windows": { "resources": { "cpu": { "maximum": 5000 } } } ``` ### Storage `storage` is an OPTIONAL configuration for the container's storage usage. The following parameters can be specified: * **`iops`** *(uint64, OPTIONAL)* - specifies the maximum IO operations per second for the system drive of the container. * **`bps`** *(uint64, OPTIONAL)* - specifies the maximum bytes per second for the system drive of the container. * **`sandboxSize`** *(uint64, OPTIONAL)* - specifies the minimum size of the system drive in bytes. #### Example ```json "windows": { "resources": { "storage": { "iops": 50 } } } ``` ## Network You can configure a container's networking options via the OPTIONAL `network` field of the Windows configuration. The following parameters can be specified: * **`endpointList`** *(array of strings, OPTIONAL)* - list of HNS (Host Network Service) endpoints that the container should connect to. * **`allowUnqualifiedDNSQuery`** *(bool, OPTIONAL)* - specifies if unqualified DNS name resolution is allowed. * **`DNSSearchList`** *(array of strings, OPTIONAL)* - comma separated list of DNS suffixes to use for name resolution. * **`networkSharedContainerName`** *(string, OPTIONAL)* - name (ID) of the container that we will share with the network stack. * **`networkNamespace`** *(string, OPTIONAL)* - name (ID) of the network namespace that will be used for the container. If a network namespace is specified no other parameter must be specified. ### Example ```json "windows": { "network": { "endpointList": [ "7a010682-17e0-4455-a838-02e5d9655fe6" ], "allowUnqualifiedDNSQuery": true, "DNSSearchList": [ "a.com", "b.com" ], "networkSharedContainerName": "containerName", "networkNamespace": "168f3daf-efc6-4377-b20a-2c86764ba892" } } ``` ## Credential Spec You can configure a container's group Managed Service Account (gMSA) via the OPTIONAL `credentialSpec` field of the Windows configuration. The `credentialSpec` is a JSON object whose properties are implementation-defined. For more information about gMSAs, see [Active Directory Service Accounts for Windows Containers][gMSAOverview]. For more information about tooling to generate a gMSA, see [Deployment Overview][gMSATooling]. [gMSAOverview]: https://aka.ms/windowscontainers/manage-serviceaccounts [gMSATooling]: https://aka.ms/windowscontainers/credentialspec-tools ## Servicing When a container terminates, the Host Compute Service indicates if a Windows update servicing operation is pending. You can indicate that a container should be started in a mode to apply pending servicing operations via the OPTIONAL `servicing` field of the Windows configuration. ### Example ```json "windows": { "servicing": true } ``` ## IgnoreFlushesDuringBoot You can indicate that a container should be started in a mode where disk flushes are not performed during container boot via the OPTIONAL `ignoreFlushesDuringBoot` field of the Windows configuration. ### Example ```json "windows": { "ignoreFlushesDuringBoot": true } ``` ## HyperV `hyperv` is an OPTIONAL field of the Windows configuration. If present, the container MUST be run with Hyper-V isolation. If omitted, the container MUST be run as a Windows Server container. The following parameters can be specified: * **`utilityVMPath`** *(string, OPTIONAL)* - specifies the path to the image used for the utility VM. This would be specified if using a base image which does not contain a utility VM image. If not supplied, the runtime will search the container filesystem layers from the bottom-most layer upwards, until it locates "UtilityVM", and default to that path. ### Example ```json "windows": { "hyperv": { "utilityVMPath": "C:\\path\\to\\utilityvm" } } ``` crun-1.16.1/libocispec/runtime-spec/implementations.md0000664000000000000000000000450214160576556021240 0ustar0000000000000000# Implementations The following sections link to associated projects, some of which are maintained by the OCI and some of which are maintained by external organizations.

This JSON structure is called ["Features structure"](glossary.md#features-structure). The Features structure is irrelevant to the actual availability of the features in the host operating system. Hence, the content of the Features structure SHOULD be determined on the compilation time of the runtime, not on the execution time. All properties in the Features structure except `ociVersionMin` and `ociVersionMax` MAY either be absent or have the `null` value. The `null` value MUST NOT be confused with an empty value such as `0`, `false`, `""`, `[]`, and `{}`. ## Specification version * **`ociVersionMin`** (string, REQUIRED) The minimum recognized version of the Open Container Initiative Runtime Specification. The runtime MUST accept this value as the [`ociVersion` property of `config.json`](config.md#specification-version). * **`ociVersionMax`** (string, REQUIRED) The maximum recognized version of the Open Container Initiative Runtime Specification. The runtime MUST accept this value as the [`ociVersion` property of `config.json`](config.md#specification-version). The value MUST NOT be less than the value of the `ociVersionMin` property. The Features structure MUST NOT contain properties that are not defined in this version of the Open Container Initiative Runtime Specification. ### Example ```json { "ociVersionMin": "1.0.0", "ociVersionMax": "1.1.0" } ``` ## Hooks * **`hooks`** (array of strings, OPTIONAL) The recognized names of the [hooks](config.md#posix-platform-hooks). The runtime MUST support the elements in this array as the [`hooks` property of `config.json`](config.md#posix-platform-hooks). ### Example ```json "hooks": [ "prestart", "createRuntime", "createContainer", "startContainer", "poststart", "poststop" ] ``` ## Mount Options * **`mountOptions`** (array of strings, OPTIONAL) The recognized names of the mount options, including options that might not be supported by the host operating system. The runtime MUST recognize the elements in this array as the [`options` of `mounts` objects in `config.json`](config.md#mounts). * Linux: this array SHOULD NOT contain filesystem-specific mount options that are passed to the [mount(2)][mount.2] syscall as `const void *data`. ### Example ```json "mountOptions": [ "acl", "async", "atime", "bind", "defaults", "dev", "diratime", "dirsync", "exec", "iversion", "lazytime", "loud", "mand", "noacl", "noatime", "nodev", "nodiratime", "noexec", "noiversion", "nolazytime", "nomand", "norelatime", "nostrictatime", "nosuid", "nosymfollow", "private", "ratime", "rbind", "rdev", "rdiratime", "relatime", "remount", "rexec", "rnoatime", "rnodev", "rnodiratime", "rnoexec", "rnorelatime", "rnostrictatime", "rnosuid", "rnosymfollow", "ro", "rprivate", "rrelatime", "rro", "rrw", "rshared", "rslave", "rstrictatime", "rsuid", "rsymfollow", "runbindable", "rw", "shared", "silent", "slave", "strictatime", "suid", "symfollow", "sync", "tmpcopyup", "unbindable" ] ``` ## Platform-specific features * **`linux`** (object, OPTIONAL) [Linux-specific features](features-linux.md). This MAY be set if the runtime supports `linux` platform. ## Annotations **`annotations`** (object, OPTIONAL) contains arbitrary metadata of the runtime. This information MAY be structured or unstructured. Annotations MUST be a key-value map that follows the same convention as the Key and Values of the [`annotations` property of `config.json`](config.md#annotations). However, annotations do not need to contain the possible values of the [`annotations` property of `config.json`](config.md#annotations). The current version of the spec do not provide a way to enumerate the possible values of the [`annotations` property of `config.json`](config.md#annotations). ### Example ```json "annotations": { "org.opencontainers.runc.checkpoint.enabled": "true", "org.opencontainers.runc.version": "1.1.0" } ``` ## Unsafe annotations in `config.json` **`potentiallyUnsafeConfigAnnotations`** (array of strings, OPTIONAL) contains values of [`annotations` property of `config.json`](config.md#annotations) that may potentially change the behavior of the runtime. A value that ends with "." is interpreted as a prefix of annotations. ### Example ```json "potentiallyUnsafeConfigAnnotations": [ "com.example.foo.bar", "org.systemd.property." ] ``` The example above matches `com.example.foo.bar`, `org.systemd.property.ExecStartPre`, etc. The example does not match `com.example.foo.bar.baz`. # Example Here is a full example for reference. ```json { "ociVersionMin": "1.0.0", "ociVersionMax": "1.1.0-rc.2", "hooks": [ "prestart", "createRuntime", "createContainer", "startContainer", "poststart", "poststop" ], "mountOptions": [ "async", "atime", "bind", "defaults", "dev", "diratime", "dirsync", "exec", "iversion", "lazytime", "loud", "mand", "noatime", "nodev", "nodiratime", "noexec", "noiversion", "nolazytime", "nomand", "norelatime", "nostrictatime", "nosuid", "nosymfollow", "private", "ratime", "rbind", "rdev", "rdiratime", "relatime", "remount", "rexec", "rnoatime", "rnodev", "rnodiratime", "rnoexec", "rnorelatime", "rnostrictatime", "rnosuid", "rnosymfollow", "ro", "rprivate", "rrelatime", "rro", "rrw", "rshared", "rslave", "rstrictatime", "rsuid", "rsymfollow", "runbindable", "rw", "shared", "silent", "slave", "strictatime", "suid", "symfollow", "sync", "tmpcopyup", "unbindable" ], "linux": { "namespaces": [ "cgroup", "ipc", "mount", "network", "pid", "user", "uts" ], "capabilities": [ "CAP_CHOWN", "CAP_DAC_OVERRIDE", "CAP_DAC_READ_SEARCH", "CAP_FOWNER", "CAP_FSETID", "CAP_KILL", "CAP_SETGID", "CAP_SETUID", "CAP_SETPCAP", "CAP_LINUX_IMMUTABLE", "CAP_NET_BIND_SERVICE", "CAP_NET_BROADCAST", "CAP_NET_ADMIN", "CAP_NET_RAW", "CAP_IPC_LOCK", "CAP_IPC_OWNER", "CAP_SYS_MODULE", "CAP_SYS_RAWIO", "CAP_SYS_CHROOT", "CAP_SYS_PTRACE", "CAP_SYS_PACCT", "CAP_SYS_ADMIN", "CAP_SYS_BOOT", "CAP_SYS_NICE", "CAP_SYS_RESOURCE", "CAP_SYS_TIME", "CAP_SYS_TTY_CONFIG", "CAP_MKNOD", "CAP_LEASE", "CAP_AUDIT_WRITE", "CAP_AUDIT_CONTROL", "CAP_SETFCAP", "CAP_MAC_OVERRIDE", "CAP_MAC_ADMIN", "CAP_SYSLOG", "CAP_WAKE_ALARM", "CAP_BLOCK_SUSPEND", "CAP_AUDIT_READ", "CAP_PERFMON", "CAP_BPF", "CAP_CHECKPOINT_RESTORE" ], "cgroup": { "v1": true, "v2": true, "systemd": true, "systemdUser": true, "rdma": true }, "seccomp": { "enabled": true, "actions": [ "SCMP_ACT_ALLOW", "SCMP_ACT_ERRNO", "SCMP_ACT_KILL", "SCMP_ACT_KILL_PROCESS", "SCMP_ACT_KILL_THREAD", "SCMP_ACT_LOG", "SCMP_ACT_NOTIFY", "SCMP_ACT_TRACE", "SCMP_ACT_TRAP" ], "operators": [ "SCMP_CMP_EQ", "SCMP_CMP_GE", "SCMP_CMP_GT", "SCMP_CMP_LE", "SCMP_CMP_LT", "SCMP_CMP_MASKED_EQ", "SCMP_CMP_NE" ], "archs": [ "SCMP_ARCH_AARCH64", "SCMP_ARCH_ARM", "SCMP_ARCH_MIPS", "SCMP_ARCH_MIPS64", "SCMP_ARCH_MIPS64N32", "SCMP_ARCH_MIPSEL", "SCMP_ARCH_MIPSEL64", "SCMP_ARCH_MIPSEL64N32", "SCMP_ARCH_PPC", "SCMP_ARCH_PPC64", "SCMP_ARCH_PPC64LE", "SCMP_ARCH_RISCV64", "SCMP_ARCH_S390", "SCMP_ARCH_S390X", "SCMP_ARCH_X32", "SCMP_ARCH_X86", "SCMP_ARCH_X86_64" ], "knownFlags": [ "SECCOMP_FILTER_FLAG_TSYNC", "SECCOMP_FILTER_FLAG_SPEC_ALLOW", "SECCOMP_FILTER_FLAG_LOG" ], "supportedFlags": [ "SECCOMP_FILTER_FLAG_TSYNC", "SECCOMP_FILTER_FLAG_SPEC_ALLOW", "SECCOMP_FILTER_FLAG_LOG" ] }, "apparmor": { "enabled": true }, "selinux": { "enabled": true }, "intelRdt": { "enabled": true } }, "annotations": { "io.github.seccomp.libseccomp.version": "2.5.4", "org.opencontainers.runc.checkpoint.enabled": "true", "org.opencontainers.runc.commit": "v1.1.0-534-g26851168", "org.opencontainers.runc.version": "1.1.0+dev" } } ``` [mount.2]: https://man7.org/linux/man-pages/man2/mount.2.html crun-1.16.1/libocispec/runtime-spec/principles.md0000664000000000000000000000713613677106243020200 0ustar0000000000000000# The 5 principles of Standard Containers Define a unit of software delivery called a Standard Container. The goal of a Standard Container is to encapsulate a software component and all its dependencies in a format that is self-describing and portable, so that any compliant runtime can run it without extra dependencies, regardless of the underlying machine and the contents of the container. The specification for Standard Containers defines: 1. configuration file formats 2. a set of standard operations 3. an execution environment. A great analogy for this is the physical shipping container used by the transportation industry. Shipping containers are a fundamental unit of delivery, they can be lifted, stacked, locked, loaded, unloaded and labelled. Irrespective of their contents, by standardizing the container itself it allowed for a consistent, more streamlined and efficient set of processes to be defined. For software Standard Containers offer similar functionality by being the fundamental, standardized, unit of delivery for a software package. ## 1. Standard operations Standard Containers define a set of STANDARD OPERATIONS. They can be created, started, and stopped using standard container tools; copied and snapshotted using standard filesystem tools; and downloaded and uploaded using standard network tools. ## 2. Content-agnostic Standard Containers are CONTENT-AGNOSTIC: all standard operations have the same effect regardless of the contents. They are started in the same way whether they contain a postgres database, a php application with its dependencies and application server, or Java build artifacts. ## 3. Infrastructure-agnostic Standard Containers are INFRASTRUCTURE-AGNOSTIC: they can be run in any OCI supported infrastructure. For example, a standard container can be bundled on a laptop, uploaded to cloud storage, downloaded, run and snapshotted by a build server at a fiber hotel in Virginia, uploaded to 10 staging servers in a home-made private cloud cluster, then sent to 30 production instances across 3 public cloud regions. ## 4. Designed for automation Standard Containers are DESIGNED FOR AUTOMATION: because they offer the same standard operations regardless of content and infrastructure, Standard Containers, are extremely well-suited for automation. In fact, you could say automation is their secret weapon. Many things that once required time-consuming and error-prone human effort can now be programmed. Before Standard Containers, by the time a software component ran in production, it had been individually built, configured, bundled, documented, patched, vendored, templated, tweaked and instrumented by 10 different people on 10 different computers. Builds failed, libraries conflicted, mirrors crashed, post-it notes were lost, logs were misplaced, cluster updates were half-broken. The process was slow, inefficient and cost a fortune - and was entirely different depending on the language and infrastructure provider. ## 5. Industrial-grade delivery Standard Containers make INDUSTRIAL-GRADE DELIVERY of software a reality. Leveraging all of the properties listed above, Standard Containers are enabling large and small enterprises to streamline and automate their software delivery pipelines. Whether it is in-house devOps flows, or external customer-based software delivery mechanisms, Standard Containers are changing the way the community thinks about software packaging and delivery. crun-1.16.1/libocispec/runtime-spec/runtime-linux.md0000664000000000000000000000200013677106243020631 0ustar0000000000000000# Linux Runtime ## File descriptors By default, only the `stdin`, `stdout` and `stderr` file descriptors are kept open for the application by the runtime. The runtime MAY pass additional file descriptors to the application to support features such as [socket activation][socket-activated-containers]. Some of the file descriptors MAY be redirected to `/dev/null` even though they are open. ## Dev symbolic links While creating the container (step 2 in the [lifecycle](runtime.md#lifecycle)), runtimes MUST create the following symlinks if the source file exists after processing [`mounts`](config.md#mounts): | Source | Destination | | --------------- | ----------- | | /proc/self/fd | /dev/fd | | /proc/self/fd/0 | /dev/stdin | | /proc/self/fd/1 | /dev/stdout | | /proc/self/fd/2 | /dev/stderr | [socket-activated-containers]: http://0pointer.de/blog/projects/socket-activated-containers.html

The layout of the files is as follows: * [config-schema.json](config-schema.json) - the primary entrypoint for the [configuration](../config.md) schema * [config-linux.json](config-linux.json) - the [Linux-specific configuration sub-structure](../config-linux.md) * [config-solaris.json](config-solaris.json) - the [Solaris-specific configuration sub-structure](../config-solaris.md) * [config-windows.json](config-windows.json) - the [Windows-specific configuration sub-structure](../config-windows.md) * [state-schema.json](state-schema.json) - the primary entrypoint for the [state JSON](../runtime.md#state) schema * [defs.json](defs.json) - definitions for general types * [defs-linux.json](defs-linux.json) - definitions for Linux-specific types * [defs-windows.json](defs-windows.json) - definitions for Windows-specific types * [validate.go](validate.go) - validation utility source code ## Utility There is also included a simple utility for facilitating validation. To build it: ```bash go get github.com/xeipuuv/gojsonschema go build ./validate.go ``` Or you can just use make command to create the utility: ```bash make validate ``` Then use it like: ```bash ./validate config-schema.json /config.json ``` Or like: ```bash ./validate https://raw.githubusercontent.com/opencontainers/runtime-spec//schema/config-schema.json /config.json ```

This fixes two things: it makes diffing easier with git and it resolves fights about line wrapping length. For example, this paragraph will span three lines in the Markdown source. ## Traditionally hex settings should use JSON integers, not JSON strings For example, [`"classID": 1048577`](config-linux.md#network) instead of `"classID": "0x100001"`. The config JSON isn't enough of a UI to be worth jumping through string <-> integer hoops to support an 0x… form ([source][integer-over-hex]). ## Constant names should keep redundant prefixes For example, `CAP_KILL` instead of `KILL` in [**`process.capabilities`**](config.md#process). The redundancy reduction from removing the namespacing prefix is not useful enough to be worth trimming the upstream identifier ([source][keep-prefix]). ## Optional settings should not have pointer Go types Because in many cases the Go default for the type is a no-op in the spec (sources [here][no-pointer-for-strings], [here][no-pointer-for-slices], and [here][no-pointer-for-boolean]). The exceptions are entries where we need to distinguish between “not set†and “set to the Go default for that type†([source][pointer-when-updates-require-changes]), and this decision should be made on a per-setting case. ## Links Internal links should be [relative links][markdown-relative-links] when linking to content within the repository. Internal links should be used inline. External links should be collected at the bottom of a markdown file and used as referenced links. See 'Referenced Links' in this [markdown quick reference][markdown-quick-reference]. The use of referenced links in the markdown body helps to keep files clean and organized. This also facilitates updates of external link targets on a per-file basis. Referenced links should be kept in two alphabetically sorted sets, a general reference section followed by a man page section. To keep Pandoc happy, duplicate naming of links within pages listed in the Makefile's `DOC_FILES` variable should be avoided by appending an `_N` to the link tagname, where `N` is some number not currently in use. The organization and style of an existing reference section should be maintained unless it violates these style guidelines. An exception to these rules is when a URL is needed contextually, for example when showing an explicit link to the reader. ## Examples ### Anchoring For any given section that provides a notable example, it is ideal to have it denoted with [markdown headers][markdown-headers]. The level of header should be such that it is a subheader of the header it is an example of. #### Example ```markdown ## Some Topic ### Some Subheader #### Further Subheader ##### Example To use Further Subheader, ... ### Example To use Some Topic, ... ``` ### Content Where necessary, the values in the example can be empty or unset, but accommodate with comments regarding this intention. Where feasible, the content and values used in an example should convey the fullest use of the data structures concerned. Most commonly onlookers will intend to copy-and-paste a "working example". If the intention of the example is to be a fully utilized example, rather than a copy-and-paste example, perhaps add a comment as such. ```markdown ### Example ``` ```json { "foo": null, "bar": "" } ``` **vs.** ```markdown ### Example Following is a fully populated example (not necessarily for copy/paste use) ``` ```json { "foo": [ 1, 2, 3 ], "bar": "waffles", "bif": { "baz": "potatoes" } } ``` ### Links The following is an example of different types of links. This is shown as a complete markdown file, where the referenced links are at the bottom. ```markdown The specification repository's [glossary](glossary.md) is where readers can find definitions of commonly used terms.

A container's configuration is specified as the `config.json` for the supported platforms and details the fields that enable the creation of a container. The execution environment is specified to ensure that applications running inside a container have a consistent environment between runtimes along with common actions defined for the container's lifecycle. # Platforms Platforms defined by this specification are: * `linux`: [runtime.md](runtime.md), [config.md](config.md), [features.md](features.md), [config-linux.md](config-linux.md), [runtime-linux.md](runtime-linux.md), and [features-linux.md](features-linux.md). * `solaris`: [runtime.md](runtime.md), [config.md](config.md), [features.md](features.md), and [config-solaris.md](config-solaris.md). * `windows`: [runtime.md](runtime.md), [config.md](config.md), [features.md](features.md), and [config-windows.md](config-windows.md). * `vm`: [runtime.md](runtime.md), [config.md](config.md), [features.md](features.md), and [config-vm.md](config-vm.md). * `zos`: [runtime.md](runtime.md), [config.md](config.md), [features.md](features.md), and [config-zos.md](config-zos.md). # Table of Contents - [Introduction](spec.md) - [Notational Conventions](#notational-conventions) - [Container Principles](principles.md) - [Filesystem Bundle](bundle.md) - [Runtime and Lifecycle](runtime.md) - [Linux-specific Runtime and Lifecycle](runtime-linux.md) - [Configuration](config.md) - [Linux-specific Configuration](config-linux.md) - [Solaris-specific Configuration](config-solaris.md) - [Windows-specific Configuration](config-windows.md) - [Virtual-Machine-specific Configuration](config-vm.md) - [z/OS-specific Configuration](config-zos.md) - [Features Structure](features.md) - [Linux-specific Features Structure](features-linux.md) - [Glossary](glossary.md) # Notational Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in [RFC 2119][rfc2119]. The key words "unspecified", "undefined", and "implementation-defined" are to be interpreted as described in the [rationale for the C99 standard][c99-unspecified].

Prerequisites: - Go - current release only, earlier releases are not supported - make The following make targets are relevant for any work involving the Go packages. ### Linting The included Go source code is being examined for any linting violations not included in the standard Go compiler. Linting is done using [golangci-lint][golangci-lint]. Invocation: ```shell make lint ``` ### Tests This target executes all Go based tests. Invocation: ```shell make test make validate-examples ``` ### JSON schema formatting This target auto-formats all JSON files in the `schema` directory using the `jq` tool. Prerequisites: - [jq][jq] >=1.5 Invocation: ```shell make fmt ``` ### OCI image specification PDF/HTML documentation files This target generates a PDF/HTML version of the OCI image specification. Prerequisites: - [Docker][docker] Invocation: ```shell make docs ``` ### License header check This target checks if the source code includes necessary headers. Invocation: ```shell make check-license ``` ### Clean build artifacts This target cleans all generated/compiled artifacts. Invocation: ```shell make clean ``` ### Create PNG images from dot files This target generates PNG image files from DOT source files in the `img` directory.

The Go types and validation should be compatible with the current Go release; earlier Go releases are not supported. Additional documentation about how this group operates: - [Code of Conduct][code-of-conduct] - [Roadmap](#roadmap) - [Releases](RELEASES.md) - [Project Documentation](project.md) ## Running an OCI Image The OCI Image Format partner project is the [OCI Runtime Spec project](https://github.com/opencontainers/runtime-spec). The Runtime Specification outlines how to run a "[filesystem bundle](https://github.com/opencontainers/runtime-spec/blob/master/bundle.md)" that is unpacked on disk. At a high-level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle. At this point the OCI Runtime Bundle would be run by an OCI Runtime. This entire workflow supports the UX that users have come to expect from container engines like Docker and rkt: primarily, the ability to run an image with no additional arguments: - docker run example.com/org/app:v1.0.0 - rkt run example.com/org/app,version=v1.0.0 To support this UX the OCI Image Format contains sufficient information to launch the application on the target platform (e.g. command, arguments, environment variables, etc). ## Distributing an OCI Image The [OCI Distribution Spec Project](https://github.com/opencontainers/distribution-spec/) defines an API protocol to facilitate and standardize the distribution of content. This API includes support for pushing and pulling OCI images to an OCI conformant registry. ## FAQ **Q: What happens to AppC or Docker Image Formats?** A: Existing formats can continue to be a proving ground for technologies, as needed. The OCI Image Format project strives to provide a dependable open specification that can be shared between different tools and be evolved for years or decades of compatibility; as the deb and rpm format have. Find more [FAQ on the OCI site](https://www.opencontainers.org/faq). ## Roadmap The [GitHub milestones](https://github.com/opencontainers/image-spec/milestones) lay out the path to the future improvements. ## Contributing Development happens on GitHub for the spec. Issues are used for bugs and actionable items and longer discussions can happen on the [mailing list](#mailing-list). The specification and code is licensed under the Apache 2.0 license found in the `LICENSE` file of this repository. ### Discuss your design The project welcomes submissions, but please let everyone know what you are working on. Before undertaking a nontrivial change to this specification, send mail to the [mailing list](#mailing-list) to discuss what you plan to do. This gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits. It also guarantees that the design is sound before code is written; a GitHub pull-request is not the place for high-level discussions. Typos and grammatical errors can go straight to a pull-request. When in doubt, start on the [mailing-list](#mailing-list). ### Meetings Please see the [OCI org repository README](https://github.com/opencontainers/org#meetings) for the most up-to-date information on OCI contributor and maintainer meeting schedules. You can also find links to meeting agendas and minutes for all prior meetings. ### Mailing List You can subscribe and join the mailing list on [Google Groups](https://groups.google.com/a/opencontainers.org/forum/#!forum/dev). ### IRC OCI discussion happens on #opencontainers on Freenode ([logs][irc-logs]). ### Markdown style To keep consistency throughout the Markdown files in the Open Container spec all files should be formatted one sentence per line. This fixes two things: it makes diffing easier with git and it resolves fights about line wrapping length. For example, this paragraph will span three lines in the Markdown source. ### Git commit #### Sign your work The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from [developercertificate.org](https://developercertificate.org/)): ```text Developer Certificate of Origin Version 1.1 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 660 York Street, Suite 102, San Francisco, CA 94110 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. ``` then you just add a line to every git commit message: ```text Signed-off-by: Joe Smith ``` using your real name (sorry, no pseudonyms or anonymous contributions.) You can add the sign off when creating the git commit via `git commit -s`. ### Commit Style Simple house-keeping for clean git history. Read more on [How to Write a Git Commit Message](https://chris.beams.io/posts/git-commit/) or the Discussion section of [`git-commit(1)`](https://git-scm.com/docs/git-commit). 1. Separate the subject from body with a blank line 2. Limit the subject line to 50 characters 3. Capitalize the subject line 4. Do not end the subject line with a period 5. Use the imperative mood in the subject line 6. Wrap the body at 72 characters 7. Use the body to explain what and why vs. how - If there was important/useful/essential conversation or information, copy or include a reference 8. When possible, one keyword to scope the change in the subject (i.e. "README: ...", "runtime: ...")

The mechanisms used are regular community communication on the mailing list about progress, scheduled meetings for issue resolution and release triage, and regularly paced and communicated releases. Releases are proposed and adopted or rejected using the usual [project governance](GOVERNANCE.md) rules and procedures. An anti-pattern that we want to avoid is heavy development or discussions "late cycle" around major releases. We want to build a community that is involved and communicates consistently through all releases instead of relying on "silent periods" as a judge of stability. ## Parallel releases A single project MAY consider several motions to release in parallel. However each motion to release after the initial 0.1.0 MUST be based on a previous release that has already landed. For example, runtime-spec maintainers may propose a v1.0.0-rc2 on the 1st of the month and a v0.9.1 bugfix on the 2nd of the month. They may not propose a v1.0.0-rc3 until the v1.0.0-rc2 is accepted (on the 7th if the vote initiated on the 1st passes). ## Specifications The OCI maintains three categories of projects: specifications, applications, and conformance-testing tools. However, specification releases have special restrictions in the [OCI charter][charter]: - They are the target of backwards compatibility (§7.g), and - They are subject to the OFWa patent grant (§8.d and e). To avoid unfortunate side effects (onerous backwards compatibility requirements or Member resignations), the following additional procedures apply to specification releases: ### Planning a release Every OCI specification project SHOULD hold meetings that involve maintainers reviewing pull requests, debating outstanding issues, and planning releases. This meeting MUST be advertised on the project README and MAY happen on a phone call, video conference, or on IRC. Maintainers MUST send updates to the with results of these meetings. Before the specification reaches v1.0.0, the meetings SHOULD be weekly. Once a specification has reached v1.0.0, the maintainers may alter the cadence, but a meeting MUST be held within four weeks of the previous meeting. The release plans, corresponding milestones and estimated due dates MUST be published on GitHub (e.g. ). GitHub milestones and issues are only used for community organization and all releases MUST follow the [project governance](GOVERNANCE.md) rules and procedures. ### Timelines Specifications have a variety of different timelines in their lifecycle. - Pre-v1.0.0 specifications SHOULD release on a monthly cadence to garner feedback. - Major specification releases MUST release at least three release candidates spaced a minimum of one week apart. This means a major release like a v1.0.0 or v2.0.0 release will take 1 month at minimum: one week for rc1, one week for rc2, one week for rc3, and one week for the major release itself. Maintainers SHOULD strive to make zero breaking changes during this cycle of release candidates and SHOULD restart the three-candidate count when a breaking change is introduced. For example if a breaking change is introduced in v1.0.0-rc2 then the series would end with v1.0.0-rc4 and v1.0.0. - Minor and patch releases SHOULD be made on an as-needed basis. ## Checklist Releases usually follow a few steps: - [ ] prepare a pull-request for the release - [ ] a commit updating `./ChangeLog` - [ ] `git log --oneline --no-merges --decorate --name-status v1.0.1..HEAD | vim -` - [ ] `:% s/(pr\/\(\d*\))\(.*\)/\2 (#\1)/` to move the PR to the end of line and match previous formatting - [ ] review `(^M|^A|^D)` for impact of the commit - [ ] group commits to `Additions:`, `Minor fixes and documentation:`, `Breaking changes:` - [ ] delete the `(^M|^A|^D)` lines, `:%!grep -vE '(^M|^A|^D)'` - [ ] merge multi-commit PRs (so each line has a `(#num)` suffix) - [ ] drop hash and indent, `:'<,'> s/^\w* /^I* /` - [ ] a commit bumping `./specs-go/version.go` to next version and empty the `VersionDev` variable - [ ] a commit adding back the "+dev" to `VersionDev` - [ ] send email to - [ ] copy the exact commit hash for bumping the version from the pull-request (since master always stays as "-dev") - [ ] count the PRs since last release (that this version is tracking, in the cases of multiple branching), like `git log --pretty=oneline --no-merges --decorate $priorTag..$versionBumpCommit | grep \(pr\/ | wc -l` - [ ] get the date for a week from now, like `TZ=UTC date --date='next week'` - [ ] OPTIONAL find a cute animal gif to attach to the email, and subsequently the release description - [ ] subject line like `[image-spec VOTE] tag $versionBumpCommit as $version (closes $dateWeekFromNowUTC)` - [ ] email body like ```text Hey everyone, There have been $numPRs PRs merged since $priorTag release (https://github.com/opencontainers/image-spec/compare/$priorTag...$versionBumpCommit). $linkToPullRequest Please respond LGTM or REJECT (with reasoning). $sig ``` - [ ] edit/update the pull-request to link to the VOTE thread, from - [ ] a week later, if the vote passes, merge the PR - [ ] `git tag -s $version $versionBumpCommit` - [ ] `git push --tags` - [ ] produce release documents - [ ] git checkout the release tag, like `git checkout $version` - [ ] `make docs` - [ ] rename the output PDF and HTML file to include version, like `mv output/oci-image-spec.pdf output/oci-image-spec-$version.pdf`` - [ ] attach these docs to the release on - [ ] link to the the VOTE thread and include the passing vote count - [ ] link to the pull request that merged the release - [ ] add release notes to the website [charter]: https://github.com/opencontainers/tob/blob/main/CHARTER.md crun-1.16.1/libocispec/image-spec/annotations.md0000644000000000000000000001361714614670026017760 0ustar0000000000000000# Annotations Several components of the specification, like [Image Manifests](manifest.md) and [Descriptors](descriptor.md), feature an optional annotations property, whose format is common and defined in this section. This property contains arbitrary metadata. ## Rules - Annotations MUST be a key-value map where both the key and value MUST be strings. - While the value MUST be present, it MAY be an empty string. - Keys MUST be unique within this map, and best practice is to namespace the keys. - Keys SHOULD be named using a reverse domain notation - e.g. `com.example.myKey`. - The prefix `org.opencontainers` is reserved for keys defined in Open Container Initiative (OCI) specifications and MUST NOT be used by other specifications and extensions. - Keys using the `org.opencontainers.image` namespace are reserved for use in the OCI Image Specification and MUST NOT be used by other specifications and extensions, including other OCI specifications. - If there are no annotations then this property MUST either be absent or be an empty map. - Consumers MUST NOT generate an error if they encounter an unknown annotation key. ## Pre-Defined Annotation Keys This specification defines the following annotation keys, intended for but not limited to [image index](image-index.md), image [manifest](manifest.md), and [descriptor](descriptor.md) authors. - **org.opencontainers.image.created** date and time on which the image was built, conforming to [RFC 3339][rfc3339]. - **org.opencontainers.image.authors** contact details of the people or organization responsible for the image (freeform string) - **org.opencontainers.image.url** URL to find more information on the image (string) - **org.opencontainers.image.documentation** URL to get documentation on the image (string) - **org.opencontainers.image.source** URL to get source code for building the image (string) - **org.opencontainers.image.version** version of the packaged software - The version MAY match a label or tag in the source code repository - version MAY be [Semantic versioning-compatible](https://semver.org/) - **org.opencontainers.image.revision** Source control revision identifier for the packaged software. - **org.opencontainers.image.vendor** Name of the distributing entity, organization or individual. - **org.opencontainers.image.licenses** License(s) under which contained software is distributed as an [SPDX License Expression][spdx-license-expression]. - **org.opencontainers.image.ref.name** Name of the reference for a target (string). - SHOULD only be considered valid when on descriptors on `index.json` within [image layout](image-layout.md). - Character set of the value SHOULD conform to alphanum of `A-Za-z0-9` and separator set of `-._:@/+` - The reference must match the following [grammar](considerations.md#ebnf): ```ebnf ref ::= component ("/" component)* component ::= alphanum (separator alphanum)* alphanum ::= [A-Za-z0-9]+ separator ::= [-._:@+] | "--" ``` - **org.opencontainers.image.title** Human-readable title of the image (string) - **org.opencontainers.image.description** Human-readable description of the software packaged in the image (string) - **org.opencontainers.image.base.digest** [Digest](descriptor.md#digests) of the image this image is based on (string) - This SHOULD be the immediate image sharing zero-indexed layers with the image, such as from a Dockerfile `FROM` statement. - This SHOULD NOT reference any other images used to generate the contents of the image (e.g., multi-stage Dockerfile builds). - **org.opencontainers.image.base.name** Image reference of the image this image is based on (string) - This SHOULD be image references in the format defined by [distribution/distribution][distribution-reference]. - This SHOULD be a fully qualified reference name, without any assumed default registry. (e.g., `registry.example.com/my-org/my-image:tag` instead of `my-org/my-image:tag`). - This SHOULD be the immediate image sharing zero-indexed layers with the image, such as from a Dockerfile `FROM` statement. - This SHOULD NOT reference any other images used to generate the contents of the image (e.g., multi-stage Dockerfile builds). - If the `image.base.name` annotation is specified, the `image.base.digest` annotation SHOULD be the digest of the manifest referenced by the `image.ref.name` annotation. ## Back-compatibility with Label Schema [Label Schema][label-schema] defined a number of conventional labels for container images, and these are now superceded by annotations with keys starting **org.opencontainers.image**. While users are encouraged to use the **org.opencontainers.image** keys, tools MAY choose to support compatible annotations using the **org.label-schema** prefix as follows. | `org.opencontainers.image` prefix | `org.label-schema` prefix | Compatibility notes | |---------------------------|-------------------------|---------------------| | `created` | `build-date` | Compatible | | `url` | `url` | Compatible | | `source` | `vcs-url` | Compatible | | `version` | `version` | Compatible | | `revision` | `vcs-ref` | Compatible | | `vendor` | `vendor` | Compatible | | `title` | `name` | Compatible | | `description` | `description` | Compatible | | `documentation` | `usage` | Value is compatible if the documentation is located by a URL | | `authors` | | No equivalent in Label Schema | | `licenses` | | No equivalent in Label Schema | | `ref.name` | | No equivalent in Label Schema | | | `schema-version`| No equivalent in the OCI Image Spec | | | `docker.*`, `rkt.*` | No equivalent in the OCI Image Spec | [distribution-reference]: https://github.com/distribution/distribution/blob/d0deff9cd6c2b8c82c6f3d1c713af51df099d07b/reference/reference.go [label-schema]: https://github.com/label-schema/label-schema.org/blob/gh-pages/rc1.md [rfc3339]: https://tools.ietf.org/html/rfc3339#section-5.6 [spdx-license-expression]: https://spdx.github.io/spdx-spec/v2.3/SPDX-license-expressions/ crun-1.16.1/libocispec/image-spec/artifacts-guidance.md0000644000000000000000000000113314614670026021146 0ustar0000000000000000# Guidance for Artifacts Authors Content other than OCI container images MAY be packaged using the image manifest. When this is done, the `config.mediaType` value should not be a known OCI image config [media type](media-types.md). Historically, due to registry limitations, some tools have created non-OCI conformant artifacts using the `application/vnd.oci.image.config.v1+json` value for `config.mediaType` and values specific to the artifact in `layer[*].mediaType`. Implementation details and examples are provided in the [image manifest specification](manifest.md#guidelines-for-artifact-usage). crun-1.16.1/libocispec/image-spec/config.md0000644000000000000000000003616514614670026016673 0ustar0000000000000000# OCI Image Configuration An OCI _Image_ is an ordered collection of root filesystem changes and the corresponding execution parameters for use within a container runtime. This specification outlines the JSON format describing images for use with a container runtime and execution tool and its relationship to filesystem changesets, described in [Layers](layer.md). This section defines the `application/vnd.oci.image.config.v1+json` [media type](media-types.md). ## Terminology This specification uses the following terms: ### [Layer](layer.md) - Image filesystems are composed of _layers_. - Each layer represents a set of filesystem changes in a tar-based [layer format](layer.md), recording files to be added, changed, or deleted relative to its parent layer. - Layers do not have configuration metadata such as environment variables or default arguments - these are properties of the image as a whole rather than any particular layer. - Using a layer-based or union filesystem such as AUFS, or by computing the diff from filesystem snapshots, the filesystem changeset can be used to present a series of image layers as if they were one cohesive filesystem. ### Image JSON - Each image has an associated JSON structure which describes some basic information about the image such as date created, author, as well as execution/runtime configuration like its entrypoint, default arguments, networking, and volumes. - The JSON structure also references a cryptographic hash of each layer used by the image, and provides history information for those layers. - This JSON is considered to be immutable, because changing it would change the computed [ImageID](#imageid). - Changing it means creating a new derived image, instead of changing the existing image. ### Layer DiffID A layer DiffID is the digest over the layer's uncompressed tar archive and serialized in the descriptor digest format, e.g., `sha256:a9561eb1b190625c9adb5a9513e72c4dedafc1cb2d4c5236c9a6957ec7dfd5a9`. Layers SHOULD be packed and unpacked reproducibly to avoid changing the layer DiffID, for example by using [tar-split][] to save the tar headers. NOTE: Do not confuse DiffIDs with [layer digests](manifest.md#image-manifest-property-descriptions), often referenced in the manifest, which are digests over compressed or uncompressed content. ### Layer ChainID For convenience, it is sometimes useful to refer to a stack of layers with a single identifier. While a layer's `DiffID` identifies a single changeset, the `ChainID` identifies the subsequent application of those changesets. This ensures that we have handles referring to both the layer itself, as well as the result of the application of a series of changesets. Use in combination with `rootfs.diff_ids` while applying layers to a root filesystem to uniquely and safely identify the result. #### Definition The `ChainID` of an applied set of layers is defined with the following recursion: ```text ChainID(Lâ‚€) = DiffID(Lâ‚€) ChainID(Lâ‚€|...|Lₙ₋â‚|Lâ‚™) = Digest(ChainID(Lâ‚€|...|Lₙ₋â‚) + " " + DiffID(Lâ‚™)) ``` For this, we define the binary `|` operation to be the result of applying the right operand to the left operand. For example, given base layer `A` and a changeset `B`, we refer to the result of applying `B` to `A` as `A|B`. Above, we define the `ChainID` for a single layer (`Lâ‚€`) as equivalent to the `DiffID` for that layer. Otherwise, the `ChainID` for a set of applied layers (`Lâ‚€|...|Lₙ₋â‚|Lâ‚™`) is defined as the recursion `Digest(ChainID(Lâ‚€|...|Lₙ₋â‚) + " " + DiffID(Lâ‚™))`. #### Explanation Let's say we have layers A, B, C, ordered from bottom to top, where A is the base and C is the top. Defining `|` as a binary application operator, the root filesystem may be `A|B|C`. While it is implied that `C` is only useful when applied to `A|B`, the identifier `C` is insufficient to identify this result, as we'd have the equality `C = A|B|C`, which isn't true. The main issue is when we have two definitions of `C`, `C = C` and `C = A|B|C`. If this is true (with some handwaving), `C = x|C` where `x = any application`. This means that if an attacker can define `x`, relying on `C` provides no guarantee that the layers were applied in any order. The `ChainID` addresses this problem by being defined as a compound hash. **We differentiate the changeset `C`, from the order-dependent application `A|B|C` by saying that the resulting rootfs is identified by ChainID(A|B|C), which can be calculated by `ImageConfig.rootfs`.** Let's expand the definition of `ChainID(A|B|C)` to explore its internal structure: ```text ChainID(A) = DiffID(A) ChainID(A|B) = Digest(ChainID(A) + " " + DiffID(B)) ChainID(A|B|C) = Digest(ChainID(A|B) + " " + DiffID(C)) ``` We can replace each definition and reduce to a single equality: ```text ChainID(A|B|C) = Digest(Digest(DiffID(A) + " " + DiffID(B)) + " " + DiffID(C)) ``` Hopefully, the above is illustrative of the _actual_ contents of the `ChainID`. Most importantly, we can easily see that `ChainID(C) != ChainID(A|B|C)`, otherwise, `ChainID(C) = DiffID(C)`, which is the base case, could not be true. ### ImageID Each image's ID is given by the SHA256 hash of its [configuration JSON](#image-json). It is represented as a hexadecimal encoding of 256 bits, e.g., `sha256:a9561eb1b190625c9adb5a9513e72c4dedafc1cb2d4c5236c9a6957ec7dfd5a9`. Since the [configuration JSON](#image-json) that gets hashed references hashes of each layer in the image, this formulation of the ImageID makes images content-addressable. ## Properties Note: Any OPTIONAL field MAY also be set to null, which is equivalent to being absent. - **created** _string_, OPTIONAL An combined date and time at which the image was created, formatted as defined by [RFC 3339, section 5.6][rfc3339-s5.6]. - **author** _string_, OPTIONAL Gives the name and/or email address of the person or entity which created and is responsible for maintaining the image. - **architecture** _string_, REQUIRED The CPU architecture which the binaries in this image are built to run on. Configurations SHOULD use, and implementations SHOULD understand, values listed in the Go Language document for [`GOARCH`][go-environment]. - **os** _string_, REQUIRED The name of the operating system which the image is built to run on. Configurations SHOULD use, and implementations SHOULD understand, values listed in the Go Language document for [`GOOS`][go-environment]. - **os.version** _string_, OPTIONAL This OPTIONAL property specifies the version of the operating system targeted by the referenced blob. Implementations MAY refuse to use manifests where `os.version` is not known to work with the host OS version. Valid values are implementation-defined. e.g. `10.0.14393.1066` on `windows`. - **os.features** _array of strings_, OPTIONAL This OPTIONAL property specifies an array of strings, each specifying a mandatory OS feature. When `os` is `windows`, image indexes SHOULD use, and implementations SHOULD understand the following values: - `win32k`: image requires `win32k.sys` on the host (Note: `win32k.sys` is missing on Nano Server) - **variant** _string_, OPTIONAL The variant of the specified CPU architecture. Configurations SHOULD use, and implementations SHOULD understand, `variant` values listed in the [Platform Variants](image-index.md#platform-variants) table. - **config** _object_, OPTIONAL The execution parameters which SHOULD be used as a base when running a container using the image. This field can be `null`, in which case any execution parameters should be specified at creation of the container. - **User** _string_, OPTIONAL The username or UID which is a platform-specific structure that allows specific control over which user the process run as. This acts as a default value to use when the value is not specified when creating a container. For Linux based systems, all of the following are valid: `user`, `uid`, `user:group`, `uid:gid`, `uid:group`, `user:gid`. If `group`/`gid` is not specified, the default group and supplementary groups of the given `user`/`uid` in `/etc/passwd` and `/etc/group` from the container are applied. If `group`/`gid` is specified, supplementary groups from the container are ignored. - **ExposedPorts** _object_, OPTIONAL A set of ports to expose from a container running this image. Its keys can be in the format of: `port/tcp`, `port/udp`, `port` with the default protocol being `tcp` if not specified. These values act as defaults and are merged with any specified when creating a container. **NOTE:** This JSON structure value is unusual because it is a direct JSON serialization of the Go type `map[string]struct{}` and is represented in JSON as an object mapping its keys to an empty object. - **Env** _array of strings_, OPTIONAL Entries are in the format of `VARNAME=VARVALUE`. These values act as defaults and are merged with any specified when creating a container. - **Entrypoint** _array of strings_, OPTIONAL A list of arguments to use as the command to execute when the container starts. These values act as defaults and may be replaced by an entrypoint specified when creating a container. - **Cmd** _array of strings_, OPTIONAL Default arguments to the entrypoint of the container. These values act as defaults and may be replaced by any specified when creating a container. If an `Entrypoint` value is not specified, then the first entry of the `Cmd` array SHOULD be interpreted as the executable to run. - **Volumes** _object_, OPTIONAL A set of directories describing where the process is likely to write data specific to a container instance. **NOTE:** This JSON structure value is unusual because it is a direct JSON serialization of the Go type `map[string]struct{}` and is represented in JSON as an object mapping its keys to an empty object. - **WorkingDir** _string_, OPTIONAL Sets the current working directory of the entrypoint process in the container. This value acts as a default and may be replaced by a working directory specified when creating a container. - **Labels** _object_, OPTIONAL The field contains arbitrary metadata for the container. This property MUST use the [annotation rules](annotations.md#rules). - **StopSignal** _string_, OPTIONAL The field contains the system call signal that will be sent to the container to exit. The signal can be a signal name in the format `SIGNAME`, for instance `SIGKILL` or `SIGRTMIN+3`. - **ArgsEscaped** _boolean_, OPTIONAL `[Deprecated]` - This field is present only for legacy compatibility with Docker and should not be used by new image builders. It is used by Docker for Windows images to indicate that the `Entrypoint` or `Cmd` or both, contains only a single element array, that is a pre-escaped, and combined into a single string `CommandLine`. If `true` the value in `Entrypoint` or `Cmd` should be used as-is to avoid double escaping. Note, the exact behavior of `ArgsEscaped` is complex and subject to implementation details in Moby project. - **Memory** _integer_, OPTIONAL This property is _reserved_ for use, to [maintain compatibility](media-types.md#compatibility-matrix). - **MemorySwap** _integer_, OPTIONAL This property is _reserved_ for use, to [maintain compatibility](media-types.md#compatibility-matrix). - **CpuShares** _integer_, OPTIONAL This property is _reserved_ for use, to [maintain compatibility](media-types.md#compatibility-matrix). - **Healthcheck** _object_, OPTIONAL This property is _reserved_ for use, to [maintain compatibility](media-types.md#compatibility-matrix). - **rootfs** _object_, REQUIRED The rootfs key references the layer content addresses used by the image. This makes the image config hash depend on the filesystem hash. - **type** _string_, REQUIRED MUST be set to `layers`. Implementations MUST generate an error if they encounter a unknown value while verifying or unpacking an image. - **diff_ids** _array of strings_, REQUIRED An array of layer content hashes (`DiffIDs`), in order from first to last. - **history** _array of objects_, OPTIONAL Describes the history of each layer. The array is ordered from first to last. The object has the following fields: - **created** _string_, OPTIONAL A combined date and time at which the layer was created, formatted as defined by [RFC 3339, section 5.6][rfc3339-s5.6]. - **author** _string_, OPTIONAL The author of the build point. - **created_by** _string_, OPTIONAL The command which created the layer. - **comment** _string_, OPTIONAL A custom message set when creating the layer. - **empty_layer** _boolean_, OPTIONAL This field is used to mark if the history item created a filesystem diff. It is set to true if this history item doesn't correspond to an actual layer in the rootfs section (for example, Dockerfile's [ENV](https://docs.docker.com/engine/reference/builder/#/env) command results in no change to the filesystem). Any extra fields in the Image JSON struct are considered implementation specific and MUST NOT generate an error by any implementations which are unable to interpret them. Whitespace is OPTIONAL and implementations MAY have compact JSON with no whitespace. ## Example Here is an example image configuration JSON document: ```json,title=Image%20JSON&mediatype=application/vnd.oci.image.config.v1%2Bjson { "created": "2015-10-31T22:22:56.015925234Z", "author": "Alyssa P.

Examples of these implementations include: - A [registry implementing the distribution specification][distribution-spec], including local registries, caching proxies - An application which copies content to disk or between registries Implementations processing content SHOULD NOT generate an error if they encounter an unknown property in a known media type. Examples of these implementations include: - A [runtime implementing the runtime specification][runtime-spec] - An implementation using OCI to retrieve and utilize artifacts, e.g.: a WASM runtime ## Canonicalization - OCI Images are [content-addressable](https://en.wikipedia.org/wiki/Content-addressable_storage). See [descriptors](descriptor.md) for more. - One benefit of content-addressable storage is easy deduplication. - Many images might depend on a particular [layer](layer.md), but there will only be one blob in the [store](image-layout.md). - With a different serialization, that same semantic layer would have a different hash, and if both versions of the layer are referenced there will be two blobs with the same semantic content. - To allow efficient storage, implementations serializing content for blobs SHOULD use a canonical serialization. - This increases the chance that different implementations can push the same semantic content to the store without creating redundant blobs. ### JSON [JSON][JSON] content SHOULD be serialized as [canonical JSON][canonical-json]. Of the [OCI Image Format Specification media types](media-types.md), all the types ending in `+json` contain JSON content. Implementations: - [Go][Go]: [github.com/docker/go][docker-go], which claims to implement [canonical JSON][canonical-json] except for Unicode normalization. ## EBNF For field formats described in this specification, we use a limited subset of [Extended Backus-Naur Form][ebnf], similar to that used by the [XML specification][xmlebnf]. Grammars present in the OCI specification are regular and can be converted to a single regular expressions. However, regular expressions are avoided to limit ambiguity between regular expression syntax. By defining a subset of EBNF used here, the possibility of variation, misunderstanding or ambiguities from linking to a larger specification can be avoided. Grammars are made up of rules in the following form: ```ebnf symbol ::= expression ``` We can say we have the production identified by symbol if the input is matched by the expression. Whitespace is completely ignored in rule definitions. ### Expressions The simplest expression is the literal, surrounded by quotes: ```ebnf literal ::= "matchthis" ``` The above expression defines a symbol, "literal", that matches the exact input of "matchthis". Character classes are delineated by brackets (`[]`), describing either a set, range or multiple range of characters: ```ebnf set := [abc] range := [A-Z] ``` The above symbol "set" would match one character of either "a", "b" or "c". The symbol "range" would match any character, "A" to "Z", inclusive. Currently, only matching for 7-bit ascii literals and character classes is defined, as that is all that is required by this specification. Multiple character ranges and explicit characters can be specified in a single character classes, as follows: ```ebnf multipleranges := [a-zA-Z=-] ``` The above matches the characters in the range `A` to `Z`, `a` to `z` and the individual characters `-` and `=`. Expressions can be made up of one or more expressions, such that one must be followed by the other. This is known as an implicit concatenation operator. For example, to satisfy the following rule, both `A` and `B` must be matched to satisfy the rule: ```ebnf symbol ::= A B ``` Each expression must be matched once and only once, `A` followed by `B`. To support the description of repetition and optional match criteria, the postfix operators `*` and `+` are defined. `*` indicates that the preceding expression can be matched zero or more times. `+` indicates that the preceding expression must be matched one or more times. These appear in the following form: ```ebnf zeroormore ::= expression* oneormore ::= expression+ ``` Parentheses are used to group expressions into a larger expression: ```ebnf group ::= (A B) ``` Like simpler expressions above, operators can be applied to groups, as well. To allow for alternates, we also define the infix operator `|`. ```ebnf oneof ::= A | B ``` The above indicates that the expression should match one of the expressions, `A` or `B`. ### Precedence The operator precedence is in the following order: - Terminals (literals and character classes) - Grouping `()` - Unary operators `+*` - Concatenation - Alternates `|` The precedence can be better described using grouping to show equivalents. Concatenation has higher precedence than alternates, such `A B | C D` is equivalent to `(A B) | (C D)`. Unary operators have higher precedence than alternates and concatenation, such that `A+ | B+` is equivalent to `(A+) | (B+)`. ### Examples The following combines the previous definitions to match a simple, relative path name, describing the individual components: ```ebnf path ::= component ("/" component)* component ::= [a-z]+ ``` The production "component" is one or more lowercase letters. A "path" is then at least one component, possibly followed by zero or more slash-component pairs. The above can be converted into the following regular expression: ```regex [a-z]+(?:/[a-z]+)* ``` [canonical-json]: https://wiki.laptop.org/go/Canonical_JSON [distribution-spec]: https://github.com/opencontainers/distribution-spec/blob/main/spec.md [docker-go]: https://github.com/docker/go/ [ebnf]: https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form [Go]: https://golang.org/ [JSON]: https://json.org/ [runtime-spec]: https://github.com/opencontainers/runtime-spec/blob/main/spec.md [xmlebnf]: https://www.w3.org/TR/REC-xml/#sec-notation crun-1.16.1/libocispec/image-spec/conversion.md0000644000000000000000000002263314614670026017606 0ustar0000000000000000# Conversion to OCI Runtime Configuration When extracting an OCI Image into an [OCI Runtime bundle][oci-runtime-bundle], two orthogonal components of the extraction are relevant: 1. Extraction of the root filesystem from the set of [filesystem layers](layer.md). 2. Conversion of the [image configuration blob](config.md) to an [OCI Runtime configuration blob][oci-runtime-config]. This section defines how to convert an `application/vnd.oci.image.config.v1+json` blob to an [OCI runtime configuration blob][oci-runtime-config] (the latter component of extraction). The former component of extraction is defined [elsewhere](layer.md) and is orthogonal to configuration of a runtime bundle. The values of runtime configuration properties not specified by this document are implementation-defined. A converter MUST rely on the OCI image configuration to build the OCI runtime configuration as described by this document; this will create the "default generated runtime configuration". The "default generated runtime configuration" MAY be overridden or combined with externally provided inputs from the caller. In addition, a converter MAY have its own implementation-defined defaults and extensions which MAY be combined with the "default generated runtime configuration". The restrictions in this document refer only to combining implementation-defined defaults with the "default generated runtime configuration". Externally provided inputs are considered to be a modification of the `application/vnd.oci.image.config.v1+json` used as a source, and such modifications have no restrictions. For example, externally provided inputs MAY cause an environment variable to be added, removed or changed. However an implementation-defined default SHOULD NOT result in an environment variable being removed or changed. [oci-runtime-bundle]: https://github.com/opencontainers/runtime-spec/blob/v1.0.0/bundle.md [oci-runtime-config]: https://github.com/opencontainers/runtime-spec/blob/v1.0.0/config.md ## Verbatim Fields Certain image configuration fields have an identical counterpart in the runtime configuration. Some of these are purely annotation-based fields, and have been extracted into a [separate subsection](#annotation-fields). A compliant configuration converter MUST extract the following fields verbatim to the corresponding field in the generated runtime configuration: | Image Field | Runtime Field | Notes | | ------------------- | --------------- | ----- | | `Config.WorkingDir` | `process.cwd` | | | `Config.Env` | `process.env` | 1 | | `Config.Entrypoint` | `process.args` | 2 | | `Config.Cmd` | `process.args` | 2 | 1. The converter MAY add additional entries to `process.env` but it SHOULD NOT add entries that have variable names present in `Config.Env`. 2. If both `Config.Entrypoint` and `Config.Cmd` are specified, the converter MUST append the value of `Config.Cmd` to the value of `Config.Entrypoint` and set `process.args` to that combined value. ### Annotation Fields These fields all affect the `annotations` of the runtime configuration, and are thus subject to [precedence](#annotations). | Image Field | Runtime Field | Notes | | ------------------- | --------------- | ----- | | `os` | `annotations` | 1,2 | | `architecture` | `annotations` | 1,3 | | `variant` | `annotations` | 1,4 | | `os.version` | `annotations` | 1,5 | | `os.features` | `annotations` | 1,6 | | `author` | `annotations` | 1,7 | | `created` | `annotations` | 1,8 | | `Config.Labels` | `annotations` | | | `Config.StopSignal` | `annotations` | 1,9 | 1. If a user has explicitly specified this annotation with `Config.Labels`, then the value specified in this field takes lower [precedence](#annotations) and the converter MUST instead use the value from `Config.Labels`. 2. The value of this field MUST be set as the value of `org.opencontainers.image.os` in `annotations`. 3. The value of this field MUST be set as the value of `org.opencontainers.image.architecture` in `annotations`. 4. The value of this field MUST be set as the value of `org.opencontainers.image.variant` in `annotations`. 5. The value of this field MUST be set as the value of `org.opencontainers.image.os.version` in `annotations`. 6. The value of this field MUST be set as the value of `org.opencontainers.image.os.features` in `annotations`. 7. The value of this field MUST be set as the value of `org.opencontainers.image.author` in `annotations`. 8. The value of this field MUST be set as the value of `org.opencontainers.image.created` in `annotations`. 9. The value of this field MUST be set as the value of `org.opencontainers.image.stopSignal` in `annotations`. ## Parsed Fields Certain image configuration fields have a counterpart that must first be translated. A compliant configuration converter SHOULD parse all of these fields and set the corresponding fields in the generated runtime configuration: | Image Field | Runtime Field | | ------------------- | --------------- | | `Config.User` | `process.user.*` | The method of parsing the above image fields are described in the following sections. ### `Config.User` If the values of [`user` or `group`](config.md#properties) in `Config.User` are numeric (`uid` or `gid`) then the values MUST be copied verbatim to `process.user.uid` and `process.user.gid` respectively. If the values of [`user` or `group`](config.md#properties) in `Config.User` are not numeric (`user` or `group`) then a converter SHOULD resolve the user information using a method appropriate for the container's context. For Unix-like systems, this MAY involve resolution through NSS or parsing `/etc/passwd` from the extracted container's root filesystem to determine the values of `process.user.uid` and `process.user.gid`. In addition, a converter SHOULD set the value of `process.user.additionalGids` to a value corresponding to the user in the container's context described by `Config.User`. For Unix-like systems, this MAY involve resolution through NSS or parsing `/etc/group` and determining the group memberships of the user specified in `process.user.uid`. The converter SHOULD NOT modify `process.user.additionalGids` if the value of [`user`](config.md#properties) in `Config.User` is numeric or if `Config.User` specifies a group. If `Config.User` is not defined, the converted `process.user` value is implementation-defined. If `Config.User` does not correspond to a user in the container's context, the converter MUST return an error. ## Optional Fields Certain image configuration fields are not applicable to all conversion use cases, and thus are optional for configuration converters to implement. A compliant configuration converter SHOULD provide a way for users to extract these fields into the generated runtime configuration: | Image Field | Runtime Field | Notes | | --------------------- | ------------------ | ----- | | `Config.ExposedPorts` | `annotations` | 1 | | `Config.Volumes` | `mounts` | 2 | 1. The runtime configuration does not have a corresponding field for this image field. However, converters SHOULD set the [`org.opencontainers.image.exposedPorts` annotation](#configexposedports). 2. Implementations SHOULD provide mounts for these locations such that application data is not written to the container's root filesystem. If a converter implements conversion for this field using mountpoints, it SHOULD set the `destination` of the mountpoint to the value specified in `Config.Volumes`. An implementation MAY seed the contents of the mount with data in the image at the same location. If a _new_ image is created from a container based on the image described by this configuration, data in these paths SHOULD NOT be included in the _new_ image. The other `mounts` fields are platform and context dependent, and thus are implementation-defined. Note that the implementation of `Config.Volumes` need not use mountpoints, as it is effectively a mask of the filesystem. ### `Config.ExposedPorts` The OCI runtime configuration does not provide a way of expressing the concept of "container exposed ports". However, converters SHOULD set the **org.opencontainers.image.exposedPorts** annotation, unless doing so will [cause a conflict](#annotations). **org.opencontainers.image.exposedPorts** is the list of values that correspond to the [keys defined for `Config.ExposedPorts`](config.md) (string, comma-separated values). ## Annotations There are three ways of annotating an OCI image in this specification: 1. `Config.Labels` in the [configuration](config.md) of the image. 2. `annotations` in the [manifest](manifest.md) of the image. 3. `annotations` in the [image index](image-index.md) of the image. In addition, there are also implicit annotations that are defined by this section which are determined from the values of the image configuration. A converter SHOULD NOT attempt to extract annotations from [manifests](manifest.md) or [image indices](image-index.md). If there is a conflict (same key but different value) between an implicit annotation (or annotation in [manifests](manifest.md) or [image indices](image-index.md)) and an explicitly specified annotation in `Config.Labels`, the value specified in `Config.Labels` MUST take precedence. A converter MAY add annotations which have keys not specified in the image. A converter MUST NOT modify the values of annotations specified in the image. crun-1.16.1/libocispec/image-spec/descriptor.md0000644000000000000000000002721214614670026017575 0ustar0000000000000000# OCI Content Descriptors - An OCI image consists of several different components, arranged in a [Merkle Directed Acyclic Graph (DAG)](https://en.wikipedia.org/wiki/Merkle_tree). - References between components in the graph are expressed through _Content Descriptors_. - A Content Descriptor (or simply _Descriptor_) describes the disposition of the targeted content. - A Content Descriptor includes the type of the content, a content identifier (_digest_), and the byte-size of the raw content. Optionally, it includes the type of artifact it is describing. - Descriptors SHOULD be embedded in other formats to securely reference external content. - Other formats SHOULD use descriptors to securely reference external content. This section defines the `application/vnd.oci.descriptor.v1+json` [media type](media-types.md). ## Properties A descriptor consists of a set of properties encapsulated in key-value fields. The following fields contain the primary properties that constitute a Descriptor: - **`mediaType`** *string* This REQUIRED property contains the media type of the referenced content. Values MUST comply with [RFC 6838][rfc6838], including the [naming requirements in its section 4.2][rfc6838-s4.2]. The OCI image specification defines [several of its own MIME types](media-types.md) for resources defined in the specification. - **`digest`** *string* This REQUIRED property is the _digest_ of the targeted content, conforming to the requirements outlined in [Digests](#digests). Retrieved content SHOULD be verified against this digest when consumed via untrusted sources. - **`size`** *int64* This REQUIRED property specifies the size, in bytes, of the raw content. This property exists so that a client will have an expected size for the content before processing. If the length of the retrieved content does not match the specified length, the content SHOULD NOT be trusted. - **`urls`** *array of strings* This OPTIONAL property specifies a list of URIs from which this object MAY be downloaded. Each entry MUST conform to [RFC 3986][rfc3986]. Entries SHOULD use the `http` and `https` schemes, as defined in [RFC 7230][rfc7230-s2.7]. - **`annotations`** *string-string map* This OPTIONAL property contains arbitrary metadata for this descriptor. This OPTIONAL property MUST use the [annotation rules](annotations.md#rules). - **`data`** *string* This OPTIONAL property contains an embedded representation of the referenced content. Values MUST conform to the Base 64 encoding, as defined in [RFC 4648][rfc4648-s4]. The decoded data MUST be identical to the referenced content and SHOULD be verified against the [`digest`](#digests) and `size` fields by content consumers. See [Embedded Content](#embedded-content) for when this is appropriate. - **`artifactType`** *string* This OPTIONAL property contains the type of an artifact when the descriptor points to an artifact. This is the value of the config descriptor `mediaType` when the descriptor references an [image manifest](manifest.md). If defined, the value MUST comply with [RFC 6838][rfc6838], including the [naming requirements in its section 4.2][rfc6838-s4.2], and MAY be registered with [IANA][iana]. Descriptors pointing to [`application/vnd.oci.image.manifest.v1+json`](manifest.md) SHOULD include the extended field `platform`, see [Image Index Property Descriptions](image-index.md#image-index-property-descriptions) for details. ### Reserved Extended _Descriptor_ field additions proposed in other OCI specifications SHOULD first be considered for addition into this specification. ## Digests The _digest_ property of a Descriptor acts as a content identifier, enabling [content addressability](https://en.wikipedia.org/wiki/Content-addressable_storage). It uniquely identifies content by taking a [collision-resistant hash](https://en.wikipedia.org/wiki/Cryptographic_hash_function) of the bytes. If the _digest_ can be communicated in a secure manner, one can verify content from an insecure source by recalculating the digest independently, ensuring the content has not been modified. The value of the `digest` property is a string consisting of an _algorithm_ portion and an _encoded_ portion. The _algorithm_ specifies the cryptographic hash function and encoding used for the digest; the _encoded_ portion contains the encoded result of the hash function. A digest string MUST match the following [grammar](considerations.md#ebnf): ```ebnf digest ::= algorithm ":" encoded algorithm ::= algorithm-component (algorithm-separator algorithm-component)* algorithm-component ::= [a-z0-9]+ algorithm-separator ::= [+._-] encoded ::= [a-zA-Z0-9=_-]+ ``` Note that _algorithm_ MAY impose algorithm-specific restriction on the grammar of the _encoded_ portion. See also [Registered Algorithms](#registered-algorithms). Some example digest strings include the following: | digest | algorithm | Registered | |---------------------------------------------------------------------------|-----------------------------|------------| | `sha256:6c3c624b58dbbcd3c0dd82b4c53f04194d1247c6eebdaab7c610cf7d66709b3b` | [SHA-256](#sha-256) | Yes | | `sha512:401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b372742...` | [SHA-512](#sha-512) | Yes | | `multihash+base58:QmRZxt2b1FVZPNqd8hsiykDL3TdBDeTSPX9Kv46HmX4Gx8` | Multihash | No | | `sha256+b64u:LCa0a2j_xo_5m0U8HTBBNBNCLXBkg7-g-YpeiGJm564` | SHA-256 with urlsafe base64 | No | Please see [Registered Algorithms](#registered-algorithms) for a list of registered algorithms. Implementations SHOULD allow digests with unrecognized algorithms to pass validation if they comply with the above grammar. While `sha256` will only use hex encoded digests, separators in _algorithm_ and alphanumerics in _encoded_ are included to allow for extensions. As an example, we can parameterize the encoding and algorithm as `multihash+base58:QmRZxt2b1FVZPNqd8hsiykDL3TdBDeTSPX9Kv46HmX4Gx8`, which would be considered valid but unregistered by this specification. ### Verification Before consuming content targeted by a descriptor from untrusted sources, the byte content SHOULD be verified against the digest string. Before calculating the digest, the size of the content SHOULD be verified to reduce hash collision space. Heavy processing before calculating a hash SHOULD be avoided. Implementations MAY employ [canonicalization](considerations.md#canonicalization) of the underlying content to ensure stable content identifiers. ### Digest calculations A _digest_ is calculated by the following pseudo-code, where `H` is the selected hash algorithm, identified by string ``: ```text let ID(C) = Descriptor.digest let C = let D = ':' + Encode(H(C)) let verified = ID(C) == D ``` Above, we define the content identifier as `ID(C)`, extracted from the `Descriptor.digest` field. Content `C` is a string of bytes. Function `H` returns the hash of `C` in bytes and is passed to function `Encode` and prefixed with the algorithm to obtain the digest. The result `verified` is true if `ID(C)` is equal to `D`, confirming that `C` is the content identified by `D`. After verification, the following is true: ```text D == ID(C) == ':' + Encode(H(C)) ``` The _digest_ is confirmed as the content identifier by independently calculating the _digest_. ### Registered algorithms While the _algorithm_ component of the digest string allows the use of a variety of cryptographic algorithms, compliant implementations SHOULD use [SHA-256](#sha-256). The following algorithm identifiers are currently defined by this specification: | algorithm identifier | algorithm | |----------------------|---------------------| | `sha256` | [SHA-256](#sha-256) | | `sha512` | [SHA-512](#sha-512) | If a useful algorithm is not included in the above table, it SHOULD be submitted to this specification for registration. #### SHA-256 [SHA-256][rfc4634-s4.1] is a collision-resistant hash function, chosen for ubiquity, reasonable size and secure characteristics. Implementations MUST implement SHA-256 digest verification for use in descriptors. When the _algorithm identifier_ is `sha256`, the _encoded_ portion MUST match `/[a-f0-9]{64}/`. Note that `[A-F]` MUST NOT be used here. #### SHA-512 [SHA-512][rfc4634-s4.2] is a collision-resistant hash function which [may be more performant][sha256-vs-sha512] than [SHA-256](#sha-256) on some CPUs. Implementations MAY implement SHA-512 digest verification for use in descriptors. When the _algorithm identifier_ is `sha512`, the _encoded_ portion MUST match `/[a-f0-9]{128}/`. Note that `[A-F]` MUST NOT be used here. ## Embedded Content In many contexts, such as when downloading content over a network, resolving a descriptor to its content has a measurable fixed "roundtrip" latency cost. For large blobs, the fixed cost is usually inconsequential, as the majority of time will be spent actually fetching the content. For very small blobs, the fixed cost can be quite significant. Implementations MAY choose to embed small pieces of content directly within a descriptor to avoid roundtrips. Implementations MUST NOT populate the `data` field in situations where doing so would modify existing content identifiers. For example, a registry MUST NOT arbitrarily populate `data` fields within uploaded manifests, as that would modify the content identifier of those manifests. In contrast, a client MAY populate the `data` field before uploading a manifest, because the manifest would not yet have a content identifier in the registry. Implementations SHOULD consider portability when deciding whether to embed data, as some providers are known to refuse to accept or parse manifests that exceed a certain size. ## Examples The following example describes a [_Manifest_](manifest.md#image-manifest) with a content identifier of "sha256:5b0bcabd1ed22e9fb1310cf6c2dec7cdef19f0ad69efa1f392e94a4333501270" and a size of 7682 bytes: ```json,title=Content%20Descriptor&mediatype=application/vnd.oci.descriptor.v1%2Bjson { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7682, "digest": "sha256:5b0bcabd1ed22e9fb1310cf6c2dec7cdef19f0ad69efa1f392e94a4333501270" } ``` In the following example, the descriptor indicates that the referenced manifest is retrievable from a particular URL: ```json,title=Content%20Descriptor&mediatype=application/vnd.oci.descriptor.v1%2Bjson { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7682, "digest":

artifact it is referencing: ```json,title=Content%20Descriptor&mediatype=application/vnd.oci.descriptor.v1%2Bjson { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 123, "digest":

The image index is a higher-level manifest which points to specific [image manifests](manifest.md), ideal for one or more platforms. While the use of an image index is OPTIONAL for image providers, image consumers SHOULD be prepared to process them. This section defines the `application/vnd.oci.image.index.v1+json` [media type](media-types.md). For the media type(s) that this document is compatible with, see the [matrix][matrix]. ## _Image Index_ Property Descriptions - **`schemaVersion`** *int* This REQUIRED property specifies the image manifest schema version. For this version of the specification, this MUST be `2` to ensure backward compatibility with older versions of Docker. The value of this field will not change. This field MAY be removed in a future version of the specification. - **`mediaType`** *string* This property SHOULD be used and [remain compatible][matrix] with earlier versions of this specification and with other similar external formats. When used, this field MUST contain the media type `application/vnd.oci.image.index.v1+json`. This field usage differs from the [descriptor](descriptor.md#properties) use of `mediaType`. - **`artifactType`** *string* This OPTIONAL property contains the type of an artifact when the manifest is used for an artifact. If defined, the value MUST comply with [RFC 6838][rfc6838], including the [naming requirements in its section 4.2][rfc6838-s4.2], and MAY be registered with [IANA][iana]. - **`manifests`** *array of objects* This REQUIRED property contains a list of [manifests](manifest.md) for specific platforms. While this property MUST be present, the size of the array MAY be zero. Each object in `manifests` includes a set of [descriptor properties](descriptor.md#properties) with the following additional properties and restrictions: - **`mediaType`** *string* This [descriptor property](descriptor.md#properties) has additional restrictions for `manifests`. Implementations MUST support at least the following media types: - [`application/vnd.oci.image.manifest.v1+json`](manifest.md) Also, implementations SHOULD support the following media types: - `application/vnd.oci.image.index.v1+json` (nested index) Image indexes concerned with portability SHOULD use one of the above media types. Future versions of the spec MAY use a different mediatype (i.e. a new versioned format). An encountered `mediaType` that is unknown to the implementation MUST NOT generate an error. - **`platform`** *object* This OPTIONAL property describes the minimum runtime requirements of the image. This property SHOULD be present if its target is platform-specific. - **`architecture`** *string* This REQUIRED property specifies the CPU architecture. Image indexes SHOULD use, and implementations SHOULD understand, values listed in the Go Language document for [`GOARCH`][go-environment2]. - **`os`** *string* This REQUIRED property specifies the operating system. Image indexes SHOULD use, and implementations SHOULD understand, values listed in the Go Language document for [`GOOS`][go-environment2]. - **`os.version`** *string* This OPTIONAL property specifies the version of the operating system targeted by the referenced blob. Implementations MAY refuse to use manifests where `os.version` is not known to work with the host OS version. Valid values are implementation-defined. e.g. `10.0.14393.1066` on `windows`. - **`os.features`** *array of strings* This OPTIONAL property specifies an array of strings, each specifying a mandatory OS feature. When `os` is `windows`, image indexes SHOULD use, and implementations SHOULD understand the following values: - `win32k`: image requires `win32k.sys` on the host (Note: `win32k.sys` is missing on Nano Server) When `os` is not `windows`, values are implementation-defined and SHOULD be submitted to this specification for standardization. - **`variant`** *string* This OPTIONAL property specifies the variant of the CPU. Image indexes SHOULD use, and implementations SHOULD understand, `variant` values listed in the [Platform Variants](#platform-variants) table. - **`features`** *array of strings* This property is RESERVED for future versions of the specification. If multiple manifests match a client or runtime's requirements, the first matching entry SHOULD be used. - **`subject`** *[descriptor](descriptor.md)* This OPTIONAL property specifies a [descriptor](descriptor.md) of another manifest. This value defines a weak association to a separate [Merkle Directed Acyclic Graph (DAG)][dag] structure, and is used by the [`referrers` API][referrers-api] to include this manifest in the list of responses for the subject digest. - **`annotations`** *string-string map* This OPTIONAL property contains arbitrary metadata for the image index. This OPTIONAL property MUST use the [annotation rules](annotations.md#rules). See [Pre-Defined Annotation Keys](annotations.md#pre-defined-annotation-keys). ## Platform Variants When the variant of the CPU is not listed in the table, values are implementation-defined and SHOULD be submitted to this specification for standardization. | ISA/ABI | `architecture` | `variant` | |-----------------|----------------|-------------| | ARM 32-bit, v6 | `arm` | `v6` | | ARM 32-bit, v7 | `arm` | `v7` | | ARM 32-bit, v8 | `arm` | `v8` | | ARM 64-bit, v8 | `arm64` | `v8` | ## Example Image Index *Example showing a simple image index pointing to image manifests for two platforms:* ```json,title=Image%20Index&mediatype=application/vnd.oci.image.index.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.index.v1+json", "manifests": [ { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7143, "digest": "sha256:e692418e4cbaf90ca69d05a66403747baa33ee08806650b51fab815ad7fc331f", "platform": { "architecture": "ppc64le", "os": "linux" } }, { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7682, "digest": "sha256:5b0bcabd1ed22e9fb1310cf6c2dec7cdef19f0ad69efa1f392e94a4333501270", "platform": { "architecture": "amd64", "os": "linux" } } ], "annotations": { "com.example.key1": "value1", "com.example.key2": "value2" } } ``` ## Example Image Index with multiple media types *Example showing an image index pointing to manifests with multiple media types:* ```json,title=Image%20Index&mediatype=application/vnd.oci.image.index.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.index.v1+json", "manifests": [ { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7143, "digest": "sha256:e692418e4cbaf90ca69d05a66403747baa33ee08806650b51fab815ad7fc331f", "platform": { "architecture": "ppc64le", "os": "linux" } }, { "mediaType": "application/vnd.oci.image.index.v1+json", "size": 7682, "digest": "sha256:601570aaff1b68a61eb9c85b8beca1644e698003e0cdb5bce960f193d265a8b7" } ], "annotations": { "com.example.key1": "value1", "com.example.key2": "value2" } } ``` [dag]: https://en.wikipedia.org/wiki/Merkle_tree [go-environment2]: https://golang.org/doc/install/source#environment [iana]: https://www.iana.org/assignments/media-types/media-types.xhtml [matrix]: media-types.md#compatibility-matrix [referrers-api]: https://github.com/opencontainers/distribution-spec/blob/main/spec.md#listing-referrers [rfc6838]: https://tools.ietf.org/html/rfc6838 [rfc6838-s4.2]: https://tools.ietf.org/html/rfc6838#section-4.2 crun-1.16.1/libocispec/image-spec/image-layout.md0000644000000000000000000002045314614670026020014 0ustar0000000000000000# OCI Image Layout Specification - The OCI Image Layout is the directory structure for OCI content-addressable blobs and [location-addressable](https://en.wikipedia.org/wiki/Content-addressable_storage#Content-addressed_vs._location-addressed) references (refs). - This layout MAY be used in a variety of different transport mechanisms: archive formats (e.g. tar, zip), shared filesystem environments (e.g. nfs), or networked file fetching (e.g. http, ftp, rsync). Given an image layout and a ref, a tool can create an [OCI Runtime Specification bundle](https://github.com/opencontainers/runtime-spec/blob/v1.0.0/bundle.md) by: - Following the ref to find a [manifest](manifest.md#image-manifest), possibly via an [image index](image-index.md) - [Applying the filesystem layers](layer.md#applying) in the specified order - Converting the [image configuration](config.md) into an [OCI Runtime Specification `config.json`](https://github.com/opencontainers/runtime-spec/blob/v1.0.0/config.md) ## Content The image layout is as follows: - `blobs` directory - Contains content-addressable blobs - A blob has no schema and SHOULD be considered opaque - Directory MUST exist and MAY be empty - See [blobs](#blobs) section - `oci-layout` file - It MUST exist - It MUST be a JSON object - It MUST contain an `imageLayoutVersion` field - See [oci-layout file](#oci-layout-file) section - It MAY include additional fields - `index.json` file - It MUST exist - It MUST be an [image index](image-index.md) JSON object. - See [index.json](#indexjson-file) section ## Example Layout This is an example image layout: ```shell $ cd example.com/app/ $ find . -type f ./index.json ./oci-layout ./blobs/sha256/3588d02542238316759cbf24502f4344ffcc8a60c803870022f335d1390c13b4 ./blobs/sha256/4b0bc1c4050b03c95ef2a8e36e25feac42fd31283e8c30b3ee5df6b043155d3c ./blobs/sha256/7968321274dc6b6171697c33df7815310468e694ac5be0ec03ff053bb135e768 ``` Blobs are named by their contents: ```shell $ shasum -a 256 ./blobs/sha256/afff3924849e458c5ef237db5f89539274d5e609db5db935ed3959c90f1f2d51 afff3924849e458c5ef237db5f89539274d5e609db5db935ed3959c90f1f2d51 ./blobs/sha256/afff3924849e458c5ef237db5f89539274d5e609db5db935ed3959c90f1f2d51 ``` ## Blobs - Object names in the `blobs` subdirectories are composed of a directory for each hash algorithm, the children of which will contain the actual content. - The content of `blobs//` MUST match the digest `:` (referenced per [descriptor](descriptor.md#digests)). For example, the content of `blobs/sha256/da39a3ee5e6b4b0d3255bfef95601890afd80709` MUST match the digest `sha256:da39a3ee5e6b4b0d3255bfef95601890afd80709`. - The character set of the entry name for `` and `` MUST match the respective grammar elements described in [descriptor](descriptor.md#digests). - The blobs directory MAY contain blobs which are not referenced by any of the [refs](#indexjson-file). - The blobs directory MAY be missing referenced blobs, in which case the missing blobs SHOULD be fulfilled by an external blob store. ### Example Blobs ```shell $ cat ./blobs/sha256/9b97579de92b1c195b85bb42a11011378ee549b02d7fe9c17bf2a6b35d5cb079 | jq { "schemaVersion": 2, "manifests": [ { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7143, "digest": "sha256:afff3924849e458c5ef237db5f89539274d5e609db5db935ed3959c90f1f2d51", "platform": { "architecture": "ppc64le", "os": "linux" } }, ... ``` ```shell $ cat ./blobs/sha256/afff3924849e458c5ef237db5f89539274d5e609db5db935ed3959c90f1f2d51 | jq { "schemaVersion": 2, "config": { "mediaType": "application/vnd.oci.image.config.v1+json", "size": 7023, "digest": "sha256:5b0bcabd1ed22e9fb1310cf6c2dec7cdef19f0ad69efa1f392e94a4333501270" }, "layers": [ { "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "size": 32654, "digest": "sha256:9834876dcfb05cb167a5c24953eba58c4ac89b1adf57f28f2f9d09af107ee8f0" }, ... ``` ```shell $ cat ./blobs/sha256/5b0bcabd1ed22e9fb1310cf6c2dec7cdef19f0ad69efa1f392e94a4333501270 | jq { "architecture": "amd64", "author": "Alyssa P.

The `imageLayoutVersion` value will align with the OCI Image Specification version at the time changes to the layout are made, and will pin a given version until changes to the image layout are required. This section defines the `application/vnd.oci.layout.header.v1+json` [media type](media-types.md). ### oci-layout Example ```json,title=OCI%20Layout&mediatype=application/vnd.oci.layout.header.v1%2Bjson { "imageLayoutVersion": "1.0.0" } ``` ## index.json file This REQUIRED file is the entry point for references and descriptors of the image-layout. The [image index](image-index.md) is a multi-descriptor entry point. This index provides an established path (`/index.json`) to have an entry point for an image-layout and to discover auxiliary descriptors. - No semantic restriction is given for the "org.opencontainers.image.ref.name" annotation of descriptors. - In general the `mediaType` of each [descriptor][descriptors] object in the `manifests` field will be either `application/vnd.oci.image.index.v1+json` or `application/vnd.oci.image.manifest.v1+json`. - Future versions of the spec MAY use a different mediatype (i.e. a new versioned format). - An encountered `mediaType` that is unknown MUST NOT generate an error. **Implementor's Note:** A common use case of descriptors with a "org.opencontainers.image.ref.name" annotation is representing a "tag" for a container image. For example, an image may have a tag for different versions or builds of the software. In the wild you often see "tags" like "v1.0.0-vendor.0", "2.0.0-debug", etc. Those tags will often be represented in an image-layout repository with matching "org.opencontainers.image.ref.name" annotations like "v1.0.0-vendor.0", "2.0.0-debug", etc. ### Index Example ```json,title=Image%20Index&mediatype=application/vnd.oci.image.index.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.index.v1+json", "manifests": [ { "mediaType": "application/vnd.oci.image.index.v1+json", "size": 7143, "digest": "sha256:0228f90e926ba6b96e4f39cf294b2586d38fbb5a1e385c05cd1ee40ea54fe7fd", "annotations": { "org.opencontainers.image.ref.name": "stable-release" } }, { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 7143, "digest": "sha256:e692418e4cbaf90ca69d05a66403747baa33ee08806650b51fab815ad7fc331f", "platform": { "architecture": "ppc64le", "os": "linux" }, "annotations": { "org.opencontainers.image.ref.name": "v1.0" } }, { "mediaType": "application/xml", "size": 7143, "digest": "sha256:b3d63d132d21c3ff4c35a061adf23cf43da8ae054247e32faa95494d904a007e", "annotations": { "org.freedesktop.specifications.metainfo.version": "1.0", "org.freedesktop.specifications.metainfo.type": "AppStream" } } ], "annotations": { "com.example.index.revision": "r124356" } } ``` This illustrates an index that provides two named references and an auxiliary mediatype for this image layout. The first named reference (`stable-release`) points to another index that might contain multiple references with distinct platforms and annotations. Note that the [`org.opencontainers.image.ref.name` annotation](annotations.md) SHOULD only be considered valid when on descriptors on `index.json`. The second named reference (`v1.0`) points to a manifest that is specific to the linux/ppc64le platform.

One or more layers are applied on top of each other to create a complete filesystem. This document will use a concrete example to illustrate how to create and consume these filesystem layers. This section defines the `application/vnd.oci.image.layer.v1.tar`, `application/vnd.oci.image.layer.v1.tar+gzip`, `application/vnd.oci.image.layer.v1.tar+zstd`, `application/vnd.oci.image.layer.nondistributable.v1.tar`, `application/vnd.oci.image.layer.nondistributable.v1.tar+gzip`, and `application/vnd.oci.image.layer.nondistributable.v1.tar+zstd` [media types](media-types.md). ## `+gzip` Media Types - The media type `application/vnd.oci.image.layer.v1.tar+gzip` represents an `application/vnd.oci.image.layer.v1.tar` payload which has been compressed with [gzip][rfc1952_2]. - The media type `application/vnd.oci.image.layer.nondistributable.v1.tar+gzip` represents an `application/vnd.oci.image.layer.nondistributable.v1.tar` payload which has been compressed with [gzip][rfc1952_2]. ## `+zstd` Media Types - The media type `application/vnd.oci.image.layer.v1.tar+zstd` represents an `application/vnd.oci.image.layer.v1.tar` payload which has been compressed with [zstd][rfc8478]. - The media type `application/vnd.oci.image.layer.nondistributable.v1.tar+zstd` represents an `application/vnd.oci.image.layer.nondistributable.v1.tar` payload which has been compressed with [zstd][rfc8478]. ## Distributable Format - Layer Changesets for the [media type](media-types.md) `application/vnd.oci.image.layer.v1.tar` MUST be packaged in [tar archive][tar-archive]. - Layer Changesets for the [media type](media-types.md) `application/vnd.oci.image.layer.v1.tar` MUST NOT include duplicate entries for file paths in the resulting [tar archive][tar-archive]. ## Change Types Types of changes that can occur in a changeset are: - Additions - Modifications - Removals Additions and Modifications are represented the same in the changeset tar archive. Removals are represented using "[whiteout](#whiteouts)" file entries (See [Representing Changes](#representing-changes)). ### File Types Throughout this document section, the use of word "files" or "entries" includes the following, where supported: - regular files - directories - sockets - symbolic links - block devices - character devices - FIFOs ### File Attributes Where supported, MUST include file attributes for Additions and Modifications include: - Modification Time (`mtime`) - User ID (`uid`) - User Name (`uname`) *secondary to `uid`* - Group ID (`gid`) - Group Name (`gname`) *secondary to `gid`* - Mode (`mode`) - Extended Attributes (`xattrs`) - Symlink reference (`linkname` + symbolic link type) - [Hardlink](#hardlinks) reference (`linkname`) [Sparse files](https://en.wikipedia.org/wiki/Sparse_file) SHOULD NOT be used because they lack consistent support across tar implementations. #### Hardlinks - Hardlinks are a [POSIX concept](https://pubs.opengroup.org/onlinepubs/9699919799/functions/link.html) for having one or more directory entries for the same file on the same device. - Not all filesystems support hardlinks (e.g. [FAT](https://en.wikipedia.org/wiki/File_Allocation_Table)). - Hardlinks are possible with all [file types](#file-types) except `directories`. - Non-directory files are considered "hardlinked" when their link count is greater than 1. - Hardlinked files are on a same device (i.e. comparing Major:Minor pair) and have the same inode. - The corresponding files that share the link with the > 1 linkcount may be outside the directory that the changeset is being produced from, in which case the `linkname` is not recorded in the changeset. - Hardlinks are stored in a tar archive with type of a `1` char, per the [GNU Basic Tar Format][gnu-tar-standard] and [libarchive tar(5)][libarchive-tar]. - While approaches to deriving new or changed hardlinks may vary, a possible approach is: ```text SET LinkMap to map[< Major:Minor String >]map[< inode integer >]< path string > SET LinkNames to map[< src path string >]< dest path string > FOR each path in root path IF path type is directory CONTINUE ENDIF SET filestat to stat(path) IF filestat num of links == 1 CONTINUE ENDIF IF LinkMap[filestat device][filestat inode] is not empty SET LinkNames[path] to LinkMap[filestat device][filestat inode] ELSE SET LinkMap[filestat device][filestat inode] to path ENDIF END FOR ``` With this approach, the link map and links names of a directory could be compared against that of another directory to derive additions and changes to hardlinks. #### Platform-specific attributes Implementations on Windows MUST support these additional attributes, encoded in [PAX vendor extensions](https://github.com/libarchive/libarchive/wiki/ManPageTar5#pax-interchange-format) as follows: - [Windows file attributes](https://msdn.microsoft.com/en-us/library/windows/desktop/gg258117(v=vs.85).aspx) (`MSWINDOWS.fileattr`) - [Security descriptor](https://msdn.microsoft.com/en-us/library/cc230366.aspx) (`MSWINDOWS.rawsd`): base64-encoded self-relative binary security descriptor - Mount points (`MSWINDOWS.mountpoint`): if present on a directory symbolic link, then the link should be created as a [directory junction](https://en.wikipedia.org/wiki/NTFS_junction_point) - Creation time (`LIBARCHIVE.creationtime`) ## Creating ### Initial Root Filesystem The initial root filesystem is the base or parent layer. For this example, an image root filesystem has an initial state as an empty directory. The name of the directory is not relevant to the layer itself, only for the purpose of producing comparisons. Here is an initial empty directory structure for a changeset, with a unique directory name `rootfs-c9d-v1`. ```text rootfs-c9d-v1/ ``` ### Populate Initial Filesystem Files and directories are then created: ```text rootfs-c9d-v1/ etc/ my-app-config bin/ my-app-binary my-app-tools ``` The `rootfs-c9d-v1` directory is then created as a plain [tar archive][tar-archive] with relative path to `rootfs-c9d-v1`. Entries for the following files: ```text ./ ./etc/ ./etc/my-app-config ./bin/ ./bin/my-app-binary ./bin/my-app-tools ``` ### Populate a Comparison Filesystem Create a new directory and initialize it with a copy or snapshot of the prior root filesystem. Example commands that can preserve [file attributes](#file-attributes) to make this copy are: - [cp(1)](https://linux.die.net/man/1/cp): `cp -a rootfs-c9d-v1/ rootfs-c9d-v1.s1/` - [rsync(1)](https://linux.die.net/man/1/rsync): `rsync -aHAX rootfs-c9d-v1/ rootfs-c9d-v1.s1/` - [tar(1)](https://linux.die.net/man/1/tar): `mkdir rootfs-c9d-v1.s1 && tar --acls --xattrs -C rootfs-c9d-v1/ -c . | tar -C rootfs-c9d-v1.s1/ --acls --xattrs -x` (including `--selinux` where supported) Any [changes](#change-types) to the snapshot MUST NOT change or affect the directory it was copied from. For example `rootfs-c9d-v1.s1` is an identical snapshot of `rootfs-c9d-v1`. In this way `rootfs-c9d-v1.s1` is prepared for updates and alterations. **Implementor's Note**: *a copy-on-write or union filesystem can efficiently make directory snapshots* Initial layout of the snapshot: ```text rootfs-c9d-v1.s1/ etc/ my-app-config bin/ my-app-binary my-app-tools ``` See [Change Types](#change-types) for more details on changes. For example, add a directory at `/etc/my-app.d` containing a default config file, removing the existing config file. Also a change (in attribute or file content) to `./bin/my-app-tools` binary to handle the config layout change. Following these changes, the representation of the `rootfs-c9d-v1.s1` directory: ```text rootfs-c9d-v1.s1/ etc/ my-app.d/ default.cfg bin/ my-app-binary my-app-tools ``` ### Determining Changes When two directories are compared, the relative root is the top-level directory. The directories are compared, looking for files that have been [added, modified, or removed](#change-types). For this example, `rootfs-c9d-v1/` and `rootfs-c9d-v1.s1/` are recursively compared, each as relative root path. The following changeset is found: ```text Added: /etc/my-app.d/ Added: /etc/my-app.d/default.cfg Modified: /bin/my-app-tools Deleted: /etc/my-app-config ``` This reflects the removal of `/etc/my-app-config` and creation of a file and directory at `/etc/my-app.d/default.cfg`. `/bin/my-app-tools` has also been replaced with an updated version. ### Representing Changes A [tar archive][tar-archive] is then created which contains _only_ this changeset: - Added and modified files and directories in their entirety - Deleted files or directories marked with a [whiteout file](#whiteouts) The resulting tar archive for `rootfs-c9d-v1.s1` has the following entries: ```text ./etc/my-app.d/ ./etc/my-app.d/default.cfg ./bin/my-app-tools ./etc/.wh.my-app-config ``` To signify that the resource `./etc/my-app-config` MUST be removed when the changeset is applied, the basename of the entry is prefixed with `.wh.`. ## Applying Changesets - Layer Changesets of [media type](media-types.md) `application/vnd.oci.image.layer.v1.tar` are _applied_, rather than simply extracted as tar archives. - Applying a layer changeset requires special consideration for the [whiteout](#whiteouts) files. - In the absence of any [whiteout](#whiteouts) files in a layer changeset, the archive is extracted like a regular tar archive. ### Changeset over existing files This section specifies applying an entry from a layer changeset if the target path already exists. If the entry and the existing path are both directories, then the existing path's attributes MUST be replaced by those of the entry in the changeset. In all other cases, the implementation MUST do the semantic equivalent of the following: - removing the file path (e.g. [`unlink(2)`](https://linux.die.net/man/2/unlink) on Linux systems) - recreating the file path, based on the contents and attributes of the changeset entry ## Whiteouts - A whiteout file is an empty file with a special filename that signifies a path should be deleted. - A whiteout filename consists of the prefix `.wh.` plus the basename of the path to be deleted. - As files prefixed with `.wh.` are special whiteout markers, it is not possible to create a filesystem which has a file or directory with a name beginning with `.wh.`. - Once a whiteout is applied, the whiteout itself MUST also be hidden. - Whiteout files MUST only apply to resources in lower/parent layers. - Files that are present in the same layer as a whiteout file can only be hidden by whiteout files in subsequent layers. The following is a base layer with several resources: ```text a/ a/b/ a/b/c/ a/b/c/bar ``` When the next layer is created, the original `a/b` directory is deleted and recreated with `a/b/c/foo`: ```text a/ a/.wh..wh..opq a/b/ a/b/c/ a/b/c/foo ``` When processing the second layer, `a/.wh..wh..opq` is applied first, before creating the new version of `a/b`, regardless of the ordering in which the whiteout file was encountered. For example, the following layer is equivalent to the layer above: ```text a/ a/b/ a/b/c/ a/b/c/foo a/.wh..wh..opq ``` Implementations SHOULD generate layers such that the whiteout files appear before sibling directory entries. ### Opaque Whiteout - In addition to expressing that a single entry should be removed from a lower layer, layers may remove all of the children using an opaque whiteout entry. - An opaque whiteout entry is a file with the name `.wh..wh..opq` indicating that all siblings are hidden in the lower layer. Let's take the following base layer as an example: ```text etc/ my-app-config bin/ my-app-binary my-app-tools tools/ my-app-tool-one ``` If all children of `bin/` are removed, the next layer would have the following: ```text bin/ .wh..wh..opq ``` This is called _opaque whiteout_ format. An _opaque whiteout_ file hides _all_ children of the `bin/` including sub-directories and all descendants. Using _explicit whiteout_ files, this would be equivalent to the following: ```text bin/ .wh.my-app-binary .wh.my-app-tools .wh.tools ``` In this case, a unique whiteout file is generated for each entry. If there were more children of `bin/` in the base layer, there would be an entry for each. Note that this opaque file will apply to _all_ children, including sub-directories, other resources and all descendants. Implementations SHOULD generate layers using _explicit whiteout_ files, but MUST accept both. Any given image is likely to be composed of several of these Image Filesystem Changeset tar archives. ## Non-Distributable Layers > **NOTE**: Non-distributable layers are deprecated, and not recommended for future use. > Implementations SHOULD NOT produce new non-distributable layers. Due to legal requirements, certain layers may not be regularly distributable. Such "non-distributable" layers are typically downloaded directly from a distributor but never uploaded. Non-distributable layers SHOULD be tagged with an alternative mediatype of `application/vnd.oci.image.layer.nondistributable.v1.tar`. Implementations SHOULD NOT upload layers tagged with this media type; however, such a media type SHOULD NOT affect whether an implementation downloads the layer. [Descriptors](descriptor.md) referencing non-distributable layers MAY include `urls` for downloading these layers directly; however, the presence of the `urls` field SHOULD NOT be used to determine whether or not a layer is non-distributable.

The first goal is content-addressable images, by supporting an image model where the image's configuration can be hashed to generate a unique ID for the image and its components. The second goal is to allow multi-architecture images, through a "fat manifest" which references image manifests for platform-specific versions of an image. In OCI, this is codified in an [image index](image-index.md). The third goal is to be [translatable](conversion.md) to the [OCI Runtime Specification](https://github.com/opencontainers/runtime-spec). This section defines the `application/vnd.oci.image.manifest.v1+json` [media type](media-types.md). For the media type(s) that this is compatible with see the [matrix](media-types.md#compatibility-matrix). ## Image Manifest Unlike the [image index](image-index.md), which contains information about a set of images that can span a variety of architectures and operating systems, an image manifest provides a configuration and set of layers for a single container image for a specific architecture and operating system. ## _Image Manifest_ Property Descriptions - **`schemaVersion`** *int* This REQUIRED property specifies the image manifest schema version. For this version of the specification, this MUST be `2` to ensure backward compatibility with older versions of Docker. The value of this field will not change. This field MAY be removed in a future version of the specification. - **`mediaType`** *string* This property SHOULD be used and [remain compatible](media-types.md#compatibility-matrix) with earlier versions of this specification and with other similar external formats. When used, this field MUST contain the media type `application/vnd.oci.image.manifest.v1+json`. This field usage differs from the [descriptor](descriptor.md#properties) use of `mediaType`. - **`artifactType`** *string* This OPTIONAL property contains the type of an artifact when the manifest is used for an artifact. This MUST be set when `config.mediaType` is set to the [empty value](#guidance-for-an-empty-descriptor). If defined, the value MUST comply with [RFC 6838][rfc6838], including the [naming requirements in its section 4.2][rfc6838-s4.2], and MAY be registered with [IANA][iana]. Implementations storing or copying image manifests MUST NOT error on encountering an `artifactType` that is unknown to the implementation. - **`config`** *[descriptor](descriptor.md)* This REQUIRED property references a configuration object for a container, by digest. Beyond the [descriptor requirements](descriptor.md#properties), the value has the following additional restrictions: - **`mediaType`** *string* This [descriptor property](descriptor.md#properties) has additional restrictions for `config`. Implementations MUST NOT attempt to parse the referenced content if this media type is unknown and instead consider the referenced content as arbitrary binary data (e.g.: as `application/octet-stream`). Implementations storing or copying image manifests MUST NOT error on encountering a value that is unknown to the implementation. Implementations MUST support at least the following media types: - [`application/vnd.oci.image.config.v1+json`](config.md) Manifests for container images concerned with portability SHOULD use one of the above media types. Manifests for artifacts concerned with portability SHOULD use `config.mediaType` as described in [Guidelines for Artifact Usage](#guidelines-for-artifact-usage). If the manifest uses a different media type than the above, it MUST comply with [RFC 6838][rfc6838], including the [naming requirements in its section 4.2][rfc6838-s4.2], and MAY be registered with [IANA][iana]. To set an effectively null or empty config and maintain portability see the [guidance for an empty descriptor](#guidance-for-an-empty-descriptor) below, and `DescriptorEmptyJSON` of the reference code. - **`layers`** *array of objects* Each item in the array MUST be a [descriptor](descriptor.md). For portability, `layers` SHOULD have at least one entry. See the [guidance for an empty descriptor](#guidance-for-an-empty-descriptor) below, and `DescriptorEmptyJSON` of the reference code. When the `config.mediaType` is set to `application/vnd.oci.image.config.v1+json`, the following additional restrictions apply: - The array MUST have the base layer at index 0. - Subsequent layers MUST then follow in stack order (i.e. from `layers[0]` to `layers[len(layers)-1]`). - The final filesystem layout MUST match the result of [applying](layer.md#applying-changesets) the layers to an empty directory. - The [ownership, mode, and other attributes](layer.md#file-attributes) of the initial empty directory are unspecified. Beyond the [descriptor requirements](descriptor.md#properties), the value has the following additional restrictions: - **`mediaType`** *string* This [descriptor property](descriptor.md#properties) has additional restrictions for `layers[]`. Implementations MUST support at least the following media types: - [`application/vnd.oci.image.layer.v1.tar`](layer.md) - [`application/vnd.oci.image.layer.v1.tar+gzip`](layer.md#gzip-media-types) - [`application/vnd.oci.image.layer.nondistributable.v1.tar`](layer.md#non-distributable-layers) - [`application/vnd.oci.image.layer.nondistributable.v1.tar+gzip`](layer.md#gzip-media-types) Manifests concerned with portability SHOULD use one of the above media types. Implementations storing or copying image manifests MUST NOT error on encountering a `mediaType` that is unknown to the implementation. Entries in this field will frequently use the `+gzip` types. If the manifest uses a different media type than the above, it MUST comply with [RFC 6838][rfc6838], including the [naming requirements in its section 4.2][rfc6838-s4.2], and MAY be registered with [IANA][iana]. See [Guidelines for Artifact Usage](#guidelines-for-artifact-usage) for other uses of the `layers`. - **`subject`** *[descriptor](descriptor.md)* This OPTIONAL property specifies a [descriptor](descriptor.md) of another manifest. This value defines a weak association to a separate [Merkle Directed Acyclic Graph (DAG)][dag] structure, and is used by the [`referrers` API][referrers-api] to include this manifest in the list of responses for the subject digest. - **`annotations`** *string-string map* This OPTIONAL property contains arbitrary metadata for the image manifest. This OPTIONAL property MUST use the [annotation rules](annotations.md#rules). See [Pre-Defined Annotation Keys](annotations.md#pre-defined-annotation-keys). ## Example Image Manifest *Example showing an image manifest:* ```json,title=Manifest&mediatype=application/vnd.oci.image.manifest.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.manifest.v1+json", "config": { "mediaType": "application/vnd.oci.image.config.v1+json", "digest": "sha256:b5b2b2c507a0944348e0303114d8d93aaaa081732b86451d9bce1f432a537bc7", "size": 7023 }, "layers": [ { "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "digest": "sha256:9834876dcfb05cb167a5c24953eba58c4ac89b1adf57f28f2f9d09af107ee8f0", "size": 32654 }, { "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "digest": "sha256:3c3a4604a545cdc127456d94e421cd355bca5b528f4a9c1905b15da2eb4a4c6b", "size": 16724 }, { "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "digest": "sha256:ec4b8955958665577945c89419d1af06b5f7636b4ac3da7f12184802ad867736", "size": 73109 } ], "subject": { "mediaType": "application/vnd.oci.image.manifest.v1+json", "digest": "sha256:5b0bcabd1ed22e9fb1310cf6c2dec7cdef19f0ad69efa1f392e94a4333501270", "size": 7682 }, "annotations": { "com.example.key1": "value1", "com.example.key2": "value2" } } ``` ## Guidance for an Empty Descriptor *Implementers note*: The following is considered GUIDANCE for portability. Parts of the spec necessitate including a descriptor to a blob where some implementations of artifacts do not have associated content. While an empty blob (`size` of 0) may be preferable, practice has shown that not to be ubiquitously supported. The media type `application/vnd.oci.empty.v1+json` (`MediaTypeEmptyJSON`) has been specified for a descriptor that has no content for the implementation. The blob payload is the most minimal content that is still a valid JSON object: `{}` (`size` of 2). The blob digest of `{}` is `sha256:44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a`. The data field is optional, and if included is the base64 encoding of `{}`: `e30=`. The resulting descriptor shown here is also defined in reference code as `DescriptorEmptyJSON`: ```json,title=empty%20config&mediatype=application/vnd.oci.descriptor.v1%2Bjson { "mediaType": "application/vnd.oci.empty.v1+json", "digest": "sha256:44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a", "size": 2, "data": "e30=" } ``` ## Guidelines for Artifact Usage Content other than OCI container images MAY be packaged using the image manifest. When this is done, the `config.mediaType` value MUST be set to a value specific to the artifact type or the [empty value](#guidance-for-an-empty-descriptor). If the `config.mediaType` is set to the empty value, the `artifactType` MUST be defined. If the artifact does not need layers, a single layer SHOULD be included with a non-zero size. The suggested content for an unused `layers` array is the [empty descriptor](#guidance-for-an-empty-descriptor). The design of the artifact depends on what content is being packaged with the artifact. The decision tree below and the associated examples MAY be used to design new artifacts: 1. Does the artifact consist of at least one file or blob? If yes, continue to 2. If no, specify the `artifactType`, and set the `config` and a single `layers` element to the empty descriptor value. Here is an example of this with annotations included: ```json,title=Minimal%20artifact&mediatype=application/vnd.oci.image.manifest.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.manifest.v1+json", "artifactType": "application/vnd.example+type", "config": { "mediaType": "application/vnd.oci.empty.v1+json", "digest": "sha256:44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a", "size": 2 }, "layers": [ { "mediaType": "application/vnd.oci.empty.v1+json", "digest": "sha256:44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a", "size": 2 } ], "annotations": { "oci.opencontainers.image.created": "2023-01-02T03:04:05Z", "com.example.data": "payload" } } ``` 2. Does the artifact have additional JSON formatted metadata as configuration? If yes, continue to 3. If no, specify the `artifactType`, include the artifact in the `layers`, and set `config` to the empty descriptor value. Here is an example of this with a single layer: ```json,title=Artifact%20without%20config&mediatype=application/vnd.oci.image.manifest.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.manifest.v1+json", "artifactType": "application/vnd.example+type", "config": { "mediaType": "application/vnd.oci.empty.v1+json", "digest": "sha256:44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a", "size": 2 }, "layers": [ { "mediaType": "application/vnd.example+type", "digest": "sha256:e258d248fda94c63753607f7c4494ee0fcbe92f1a76bfdac795c9d84101eb317", "size": 1234 } ] } ``` 3. For artifacts with a config blob, specify the `artifactType` to a common value for your artifact tooling, specify the `config` with the metadata for this artifact, and include the artifact in the `layers`. Here is an example of this: ```json,title=Artifact%20with%20config&mediatype=application/vnd.oci.image.manifest.v1%2Bjson { "schemaVersion": 2, "mediaType": "application/vnd.oci.image.manifest.v1+json", "artifactType": "application/vnd.example+type", "config": { "mediaType": "application/vnd.example.config.v1+json", "digest": "sha256:5891b5b522d5df086d0ff0b110fbd9d21bb4fc7163af34d08286a2e846f6be03", "size": 123 }, "layers": [ { "mediaType": "application/vnd.example.data.v1.tar+gzip", "digest": "sha256:e258d248fda94c63753607f7c4494ee0fcbe92f1a76bfdac795c9d84101eb317", "size": 1234 } ] } ``` _Implementers note:_ artifacts have historically been created without an `artifactType` field, and tooling to work with artifacts should fallback to the `config.mediaType` value.

Implementations MAY also have expectations for the blob's media type and digest (e.g. from a [descriptor](descriptor.md) referencing the blob). - Implementations that do not have an expected media type for the blob SHOULD respect the returned media type. - Implementations that have an expected media type which matches the returned media type SHOULD respect the matched media type. - Implementations that have an expected media type which does not match the returned media type SHOULD: - Respect the expected media type if the blob matches the expected digest. Implementations MAY warn about the media type mismatch. - Return an error if the blob does not match the expected digest (as [recommended for descriptors](descriptor.md#properties)). - Return an error if they do not have an expected digest. ## Compatibility Matrix The OCI Image Specification strives to be backwards and forwards compatible when possible. Breaking compatibility with existing systems creates a burden on users whether they are build systems, distribution systems, container engines, etc. This section shows where the OCI Image Specification is compatible with formats external to the OCI Image and different versions of this specification. ### application/vnd.oci.image.index.v1+json Similar/related schema: - [application/vnd.docker.distribution.manifest.list.v2+json](https://github.com/distribution/distribution/blob/v2.8.3/docs/spec/manifest-v2-2.md#manifest-list) - `.annotations`: only present in OCI - `.[]manifests.annotations`: only present in OCI - `.[]manifests.urls`: only present in OCI ### application/vnd.oci.image.manifest.v1+json Similar/related schema: - [application/vnd.docker.distribution.manifest.v2+json](https://github.com/distribution/distribution/blob/v2.8.3/docs/spec/manifest-v2-2.md#image-manifest) - `.annotations`: only present in OCI - `.config.annotations`: only present in OCI - `.config.urls`: only present in OCI - `.[]layers.annotations`: only present in OCI ### application/vnd.oci.image.layer.v1.tar+gzip Interchangeable and fully compatible mime-types: - [application/vnd.docker.image.rootfs.diff.tar.gzip](https://github.com/moby/moby/blob/v20.10.8/image/spec/v1.2.md#creating-an-image-filesystem-changeset) ### application/vnd.oci.image.config.v1+json Similar/related schema: - [application/vnd.docker.container.image.v1+json](https://github.com/moby/moby/blob/v20.10.8/image/spec/v1.2.md#image-json-description) (Docker Image Spec v1.2) - `.config.Memory`: only present in Docker, and reserved in OCI - `.config.MemorySwap`: only present in Docker, and reserved in OCI - `.config.CpuShares`: only present in Docker, and reserved in OCI - `.config.Healthcheck`: only present in Docker, and reserved in OCI - [Moby/Docker](https://github.com/moby/moby) - `.config.ArgsEscaped`: Windows-specific Moby/Docker extension, deprecated in OCI, available for compatibility with older images. `.config.StopSignal` and `.config.Labels` are accidentally undocumented in Docker Image Spec v1.2, but these fields are not OCI-specific concepts. ## Relations The following figure shows how the above media types reference each other: ![media types](img/media-types.png) [Descriptors](descriptor.md) are used for all references.

The goal of this specification is to enable the creation of interoperable tools for building, transporting, and preparing a container image to run. ### Table of Contents - [Notational Conventions](#notational-conventions) - [Overview](#overview) - [Understanding the Specification](#understanding-the-specification) - [Media Types](media-types.md) - [Content Descriptors](descriptor.md) - [Image Layout](image-layout.md) - [Image Manifest](manifest.md) - [Image Index](image-index.md) - [Filesystem Layers](layer.md) - [Image Configuration](config.md) - [Annotations](annotations.md) - [Conversion](conversion.md) - [Considerations](considerations.md) - [Extensibility](considerations.md#extensibility) - [Canonicalization](considerations.md#canonicalization) ## Notational Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in [RFC 2119](https://tools.ietf.org/html/rfc2119) (Bradner, S., "Key words for use in RFCs to Indicate Requirement Levels", BCP 14, RFC 2119, March 1997). The key words "unspecified", "undefined", and "implementation-defined" are to be interpreted as described in the [rationale for the C99 standard][c99-unspecified]. An implementation is not compliant if it fails to satisfy one or more of the MUST, MUST NOT, REQUIRED, SHALL, or SHALL NOT requirements for the protocols it implements. An implementation is compliant if it satisfies all the MUST, MUST NOT, REQUIRED, SHALL, and SHALL NOT requirements for the protocols it implements. ## Overview At a high level the image manifest contains metadata about the contents and dependencies of the image including the content-addressable identity of one or more [filesystem layer changeset](layer.md) archives that will be unpacked to make up the final runnable filesystem. The image configuration includes information such as application arguments, environments, etc. The image index is a higher-level manifest which points to a list of manifests and descriptors. Typically, these manifests may provide different implementations of the image, possibly varying by platform or other attributes. ![build diagram](img/build-diagram.png) Once built the OCI Image can then be discovered by name, downloaded, verified by hash, trusted through a signature, and unpacked into an [OCI Runtime Bundle](https://github.com/opencontainers/runtime-spec/blob/master/bundle.md). ![runtime diagram](img/run-diagram.png) ### Understanding the Specification The [OCI Image Media Types](media-types.md) document is a starting point to understanding the overall structure of the specification. The high-level components of the spec include: - [Image Manifest](manifest.md) - a document describing the components that make up a container image - [Image Index](image-index.md) - an annotated list of manifests - [Image Layout](image-layout.md) - a filesystem layout representing the contents of an image - [Filesystem Layer](layer.md) - a changeset that describes a container's filesystem - [Image Configuration](config.md) - a document determining layer ordering and configuration of the image suitable for translation into a [runtime bundle][runtime-spec] - [Conversion](conversion.md) - a document describing how this translation should occur - [Artifacts Guidance](artifacts-guidance.md) - a document describing how to use the spec for packaging content other than OCI images - [Descriptor](descriptor.md) - a reference that describes the type, metadata and content address of referenced content Future versions of this specification may include the following OPTIONAL features: - Signatures that are based on signing image content address - Naming that is federated based on DNS and can be delegated [c99-unspecified]: https://www.open-std.org/jtc1/sc22/wg14/www/C99RationaleV5.10.pdf#page=18 [runtime-spec]: https://github.com/opencontainers/runtime-spec crun-1.16.1/libocispec/image-spec/.golangci.yml0000644000000000000000000000073014614670026017455 0ustar0000000000000000run: timeout: 10m linters: disable-all: true enable: - dupl - errorlint - gofmt - goimports - gomodguard - gosimple - govet - ineffassign - misspell - nakedret - revive - unused - staticcheck linters-settings: gofmt: simplify: true gomodguard: blocked: modules: - github.com/pkg/errors: recommendations: - errors - fmt dupl: threshold: 400 crun-1.16.1/libocispec/image-spec/.git0000664000000000000000000000007113677106241015656 0ustar0000000000000000gitdir: ../../.git/modules/libocispec/modules/image-spec crun-1.16.1/libocispec/image-spec/.markdownlint.yml0000644000000000000000000000047514614670026020411 0ustar0000000000000000# all lists use a `-` MD004: style: dash # allow tabs in code blocks (for Go) MD010: code_blocks: false # disable line length, prefer one sentence per line for PRs MD013: false # emphasis with underscore (`_emphasis_`) MD049: style: "underscore" # bold with asterisk (`**bold**`) MD050: style: "asterisk" crun-1.16.1/libocispec/image-spec/EMERITUS.md0000644000000000000000000000052314614670026016650 0ustar0000000000000000# Emeritus We would like to acknowledge previous OCI image spec maintainers and their huge contributions to our collective success: - Brandon Philips (@philips) - Brendan Burns (@brendandburns) - Jason Bouzane (@jbouzane) - John Starks (@jstarks) - Keyang Xie (@xiekeyang) We thank these members for their service to the OCI community. crun-1.16.1/libocispec/image-spec/GOVERNANCE.md0000644000000000000000000000747614614670026017060 0ustar0000000000000000# Project governance The [OCI charter][charter] §5.b.viii tasks an OCI Project's maintainers (listed in the repository's MAINTAINERS file and sometimes referred to as "the TDC", [§5.e][charter]) with: > Creating, maintaining and enforcing governance guidelines for the TDC, approved by the maintainers, and which shall be posted visibly for the TDC. This section describes generic rules and procedures for fulfilling that mandate. ## Proposing a motion A maintainer SHOULD propose a motion on the mailing list (except [security issues](#security-issues)) with another maintainer as a co-sponsor. ## Voting Voting on a proposed motion SHOULD happen on the mailing list (except [security issues](#security-issues)) with maintainers posting LGTM or REJECT. Maintainers MAY also explicitly not vote by posting ABSTAIN (which is useful to revert a previous vote). Maintainers MAY post multiple times (e.g. as they revise their position based on feedback), but only their final post counts in the tally. A proposed motion is adopted if two-thirds of votes cast, a quorum having voted, are in favor of the release. Voting SHOULD remain open for a week to collect feedback from the wider community and allow the maintainers to digest the proposed motion. Under exceptional conditions (e.g. non-major security fix releases) proposals which reach quorum with unanimous support MAY be adopted earlier. A maintainer MAY choose to reply with REJECT. A maintainer posting a REJECT MUST include a list of concerns or links to written documentation for those concerns (e.g. GitHub issues or mailing-list threads). The maintainers SHOULD try to resolve the concerns and wait for the rejecting maintainer to change their opinion to LGTM. However, a motion MAY be adopted with REJECTs, as outlined in the previous paragraphs. ## Quorum A quorum is established when at least two-thirds of maintainers have voted. For projects that are not specifications, a [motion to release](#proposing-a-motion) MAY be adopted if the tally is at least three LGTMs and no REJECTs, even if three votes does not meet the usual two-thirds quorum. ## Security issues Motions with sensitive security implications MUST be proposed on the mailing list instead of , but should otherwise follow the standard [proposal](#proposing-a-motion) process. The mailing list includes all members of the TOB. The TOB will contact the project maintainers and provide a channel for discussing and voting on the motion, but voting will otherwise follow the standard [voting](#voting) and [quorum](#quorum) rules. The TOB and project maintainers will work together to notify affected parties before making an adopted motion public. ## Amendments The [project governance](#project-governance) rules and procedures MAY be amended or replaced using the procedures themselves. The MAINTAINERS of this project governance document is the total set of MAINTAINERS from all Open Containers projects (runC, runtime-spec, and image-spec). ## Subject templates Maintainers are busy and get lots of email. To make project proposals recognizable, proposed motions SHOULD use the following subject templates. ### Proposing a motion template > [{project} VOTE]: {motion description} (closes {end of voting window}) For example: > [image-spec VOTE]: Tag 0647920 as 1.0.0-rc (closes 2016-06-03 20:00 UTC) ### Tallying results template After voting closes, a maintainer SHOULD post a tally to the motion thread with a subject template like: > [{project} {status}]: {motion description} (+{LGTMs} -{REJECTs} #{ABSTAINs}) Where `{status}` is either `adopted` or `rejected`. For example: > [image-spec adopted]: Tag 0647920 as 1.0.0-rc (+6 -0 #3) [charter]: https://github.com/opencontainers/tob/blob/main/CHARTER.md crun-1.16.1/libocispec/image-spec/.gitignore0000664000000000000000000000005213677106243017063 0ustar0000000000000000/oci-validate-examples output header.html crun-1.16.1/libocispec/image-spec/.header0000664000000000000000000000112613677106243016327 0ustar0000000000000000// Copyright 2016 The Linux Foundation // // Licensed under the Apache License, Version 2.0 (the "License"); // you may not use this file except in compliance with the License. // You may obtain a copy of the License at // // http://www.apache.org/licenses/LICENSE-2.0 // // Unless required by applicable law or agreed to in writing, software // distributed under the License is distributed on an "AS IS" BASIS, // WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. // See the License for the specific language governing permissions and // limitations under the License. crun-1.16.1/libocispec/image-spec/LICENSE0000664000000000000000000002501713677106243016110 0ustar0000000000000000 Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.

For the legacy version of YAJL see https://github.com/lloyd/yajl/tree/1.x ********************************************************************** Welcome to Yet Another JSON Library (YAJL) ## Why does the world need another C library for parsing JSON? Good question. In a review of current C JSON parsing libraries I was unable to find one that satisfies my requirements. Those are, 0. written in C 1. portable 2. robust -- as close to "crash proof" as possible 3. data representation independent 4. fast 5. generates verbose, useful error messages including context of where the error occurs in the input text. 6. can parse JSON data off a stream, incrementally 7. simple to use 8. tiny Numbers 3, 5, 6, and 7 were particularly hard to find, and were what caused me to ultimately create YAJL. This document is a tour of some of the more important aspects of YAJL. ## YAJL is Free. Permissive licensing means you can use it in open source and commercial products alike without any fees. My request beyond the licensing is that if you find bugs drop me a email, or better yet, fork and fix. Porting YAJL should be trivial, the implementation is ANSI C. If you port to new systems I'd love to hear of it and integrate your patches. ## YAJL is data representation independent. BYODR! Many JSON libraries impose a structure based data representation on you. This is a benefit in some cases and a drawback in others. YAJL uses callbacks to remain agnostic of the in-memory representation. So if you wish to build up an in-memory representation, you may do so using YAJL, but you must bring the code that defines and populates the in memory structure. This also means that YAJL can be used by other (higher level) JSON libraries if so desired. ## YAJL supports stream parsing This means you do not need to hold the whole JSON representation in textual form in memory. This makes YAJL ideal for filtering projects, where you're converting YAJL from one form to another (i.e. XML). The included JSON pretty printer is an example of such a filter program. ## YAJL is fast Minimal memory copying is performed. YAJL, when possible, returns pointers into the client provided text (i.e. for strings that have no embedded escape chars, hopefully the common case). I've put a lot of effort into profiling and tuning performance, but I have ignored a couple possible performance improvements to keep the interface clean, small, and flexible. My hope is that YAJL will perform comparably to the fastest JSON parser out there. YAJL should impose both minimal CPU and memory requirements on your application. ## YAJL is tiny. Fat free. No whip. enjoy, Lloyd - July, 2007 crun-1.16.1/libocispec/yajl/TODO0000664000000000000000000000051414025721605014504 0ustar0000000000000000* add a test for 0x1F bug * numeric overflow in integers and double * line and char offsets in the lexer and in error messages * testing: a. the permuter b. some performance comparison against json_checker. * investigate pull instead of push parsing * Handle memory allocation failures gracefully * cygwin/msys support on win32 crun-1.16.1/libocispec/yajl/compile0000755000000000000000000001635014656670145015411 0ustar0000000000000000#! /bin/sh # Wrapper for compilers which do not understand '-c -o'. scriptversion=2018-03-07.03; # UTC # Copyright (C) 1999-2020 Free Software Foundation, Inc. # Written by Tom Tromey . # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

There's no portable way to scope variables in Bourne shell # though, so actually running these functions will sometimes place # results into a variable named after the function, and often use # temporary variables in the '^_G_' namespace.
