If you are careful to # avoid using those namespaces casually in your sourcing script, things # should continue to work as you expect. And, of course, you can freely # overwrite any of the functions or variables defined here before # calling anything to customize them.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'.

Please refer to the INSTALL file for instructions on how to build. What is lxc: The container technology is actively being pushed into the mainstream linux kernel. It provides the resource management through the control groups aka process containers and resource isolation through the namespaces. The linux containers, lxc, aims to use these new functionalities to pro- vide a userspace container object which provides full resource isolation and resource control for an application or a system. The first objective of this project is to make the life easier for the ker- nel developers involved in the containers project and especially to con- tinue working on the Checkpoint/Restart new features. The lxc is small enough to easily manage a container with simple command lines and complete enough to be used for other purposes. Using lxc: Refer the lxc* man pages (generated from doc/* files) Downloading the current source code: Source for the latest released version can always be downloaded from http://linuxcontainers.org/downloads/ You can browse the up to the minute source code and change history online. http://github.com/lxc/lxc For detailed build instruction refer to INSTALL and man lxc man page but a short command line should work: ./autogen.sh && ./configure && make && sudo make install preceded by ./autogen.sh if configure do not exist yet. Troubleshooting: If you get an error message at the autogen.sh or configure stage, make sure you have, autoconf, automake, pkg-config, make and gcc installed on your machine. The configure script will usually give you hints as to what you are missing, looking for those in your package manager will usually give you the package that you need to install. Also pay a close attention to the feature summary showed at the end of the configure run, features are automatically enabled/disabled based on whether the needed development packages are installed on your machine. If you want a feature but don't know what to install, force it with --enable- and look at the error message from configure. Getting help: when you find you need help, you can check out one of the two lxc mailing list archives and register if interested: http://lists.linuxcontainers.org/listinfo/lxc-devel http://lists.linuxcontainers.org/listinfo/lxc-users Portability: lxc is still in development, so the command syntax and the API can change. The version 1.0.0 will be the frozen version. lxc is developed and tested on Linux since kernel mainline version 2.6.27 (without network) and 2.6.29 with network isolation. It's compiled with gcc, and should work on most architectures as long as the required kernel features are available. This includes (but isn't limited to): i686, x86_64, ppc, ppc64, S390, armel and armhf. AUTHOR Daniel Lezcano Seccomp with LXC ---------------- To restrict a container with seccomp, you must specify a profile which is basically a whitelist of system calls it may execute.

It will setup the container according to the configuration previously defined with the lxc-create command or with the configuration file parameter. If no configuration is defined, the default isolation is used. If no command is specified, lxc-start will use the command defined in lxc.init_cmd or if not set, the default "/sbin/init" command to run a system container. Options Run the container as a daemon. As the container has no more tty, if an error occurs nothing will be displayed, the log file can be used to check the error. (This is the default mode) Run the container in the foreground. In this mode, the container console will be attached to the current tty and signals will be routed directly to the container. Create a file with the process id. Specify the configuration file to configure the virtualization and isolation functionalities for the container. This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create). Specify a device to use for the container's console, for example /dev/tty8. If this option is not specified the current terminal will be used unless is specified. Specify a file to log the container's console output to. Assign value VAL to configuration variable KEY. This overrides any assignment done in config_file. If any file descriptors are inherited, close them. If this option is not specified, then lxc-start will exit with failure instead. Note: --daemon implies --close-all-fds. Inherit a network namespace from a name container or a pid. The network namespace will continue to be managed by the original owner. The network configuration of the starting container is ignored and the up/down scripts won't be executed. Inherit an IPC namespace from a name container or a pid. Inherit a UTS namespace from a name container or a pid.

This creation defines a set of system resources to be virtualized / isolated when a process is using the container. By default, the pids, sysv ipc and mount points are virtualized and isolated. The other system resources are shared across containers, until they are explicitly defined in the configuration file. For example, if there is no network configuration, the network will be shared between the creator of the container and the container itself, but if the network is specified, a new network stack is created for the container and the container can no longer use the network of its ancestor. The configuration file defines the different system resources to be assigned for the container. At present, the utsname, the network, the mount points, the root file system, the user namespace, and the control groups are supported. Each option in the configuration file has the form key = value fitting in one line. The '#' character means the line is a comment. List options, like capabilities and cgroups options, can be used with no value to clear any previously defined values of that option. Configuration In order to ease administration of multiple related containers, it is possible to have a container configuration file cause another file to be loaded. For instance, network configuration can be defined in one common file which is included by multiple containers. Then, if the containers are moved to another host, only one file may need to be updated. Specify the file to be included. The included file must be in the same valid lxc configuration file format. Architecture Allows one to set the architecture for the container. For example, set a 32bits architecture for a container running 32bits binaries on a 64bits host. This fixes the container scripts which rely on the architecture to do some work like downloading the packages. Specify the architecture for the container. Valid options are , , , Hostname The utsname section defines the hostname to be set for the container. That means the container can set its own hostname without changing the one from the system. That makes the hostname private for the container. specify the hostname for the container Halt signal Allows one to specify signal name or number, sent by lxc-stop to the container's init process to cleanly shutdown the container. Different init systems could use different signals to perform clean shutdown sequence. This option allows the signal to be specified in kill(1) fashion, e.g. SIGPWR, SIGRTMIN+14, SIGRTMAX-10 or plain number. The default signal is SIGPWR. specify the signal used to halt the container Reboot signal Allows one to specify signal name or number, sent by lxc-stop to reboot the container. This option allows signal to be specified in kill(1) fashion, e.g. SIGTERM, SIGRTMIN+14, SIGRTMAX-10 or plain number. The default signal is SIGINT. specify the signal used to reboot the container Stop signal Allows one to specify signal name or number, sent by lxc-stop to forcibly shutdown the container. This option allows signal to be specified in kill(1) fashion, e.g. SIGKILL, SIGRTMIN+14, SIGRTMAX-10 or plain number. The default signal is SIGKILL. specify the signal used to stop the container Init command Sets the command to use as the init system for the containers. This option is ignored when using lxc-execute. Defaults to: /sbin/init Absolute path from container rootfs to the binary to use as init. Init ID Sets the UID/GID to use for the init system, and subsequent command, executed by lxc-execute. These options are only used when lxc-execute is started in a private user namespace. Defaults to: UID(0), GID(0) UID to use within a private user namesapce for init. GID to use within a private user namesapce for init. Ephemeral Allows one to specify whether a container will be destroyed on shutdown. The only allowed values are 0 and 1. Set this to 1 to destroy a container on shutdown. Network The network section defines how the network is virtualized in the container. The network virtualization acts at layer two. In order to use the network virtualization, parameters must be specified to define the network interfaces of the container. Several virtual interfaces can be assigned and used in a container even if the system has only one physical network interface. may be used without a value to clear all previous network options. specify what kind of network virtualization to be used for the container. Each time a field is found a new round of network configuration begins. In this way, several network virtualization types can be specified for the same container, as well as assigning several network interfaces for one container. The different virtualization types can be: will cause the container to share the host's network namespace. This means the host network devices are usable in the container. It also means that if both the container and host have upstart as init, 'halt' in a container (for instance) will shut down the host. will create only the loopback interface. a virtual ethernet pair device is created with one side assigned to the container and the other side attached to a bridge specified by the option. If the bridge is not specified, then the veth pair device will be created but not attached to any bridge. Otherwise, the bridge has to be created on the system before starting the container. lxc won't handle any configuration outside of the container. By default, lxc chooses a name for the network device belonging to the outside of the container, but if you wish to handle this name yourselves, you can tell lxc to set a specific name with the option (except for unprivileged containers where this option is ignored for security reasons). a vlan interface is linked with the interface specified by the and assigned to the container. The vlan identifier is specified with the option . a macvlan interface is linked with the interface specified by the and assigned to the container. specifies the mode the macvlan will use to communicate between different macvlan on the same upper device. The accepted modes are , , and . In mode, the device never communicates with any other device on the same upper_dev (default). In mode, the new Virtual Ethernet Port Aggregator (VEPA) mode, it assumes that the adjacent bridge returns all frames where both source and destination are local to the macvlan port, i.e. the bridge is set up as a reflective relay. Broadcast frames coming in from the upper_dev get flooded to all macvlan interfaces in VEPA mode, local frames are not delivered locally. In mode, it provides the behavior of a simple bridge between different macvlan interfaces on the same port. Frames from one interface to another one get delivered directly and are not sent out externally. Broadcast frames get flooded to all other bridge ports and to the external interface, but when they come back from a reflective relay, we don't deliver them again. Since we know all the MAC addresses, the macvlan bridge mode does not require learning or STP like the bridge module does. In mode, all frames received by the physical interface are forwarded to the macvlan interface. Only one macvlan interface in mode is possible for one physical interface. an already existing interface specified by the is assigned to the container. specify an action to do for the network. activates the interface. specify the interface to be used for real network traffic. specify the maximum transfer unit for this interface. the interface name is dynamically allocated, but if another name is needed because the configuration files being used by the container use a generic name, eg. eth0, this option will rename the interface in the container. the interface mac address is dynamically allocated by default to the virtual interface, but in some cases, this is needed to resolve a mac address conflict or to always have the same link-local ipv6 address. Any "x" in address will be replaced by random value, this allows setting hwaddr templates. specify the ipv4 address to assign to the virtualized interface. Several lines specify several ipv4 addresses. The address is in format x.y.z.t/m, eg. 192.168.1.123/24. The broadcast address should be specified on the same line, right after the ipv4 address. specify the ipv4 address to use as the gateway inside the container. The address is in format x.y.z.t, eg. 192.168.1.123. Can also have the special value , which means to take the primary address from the bridge interface (as specified by the option) and use that as the gateway. is only available when using the and network types. specify the ipv6 address to assign to the virtualized interface. Several lines specify several ipv6 addresses. The address is in format x::y/m, eg. 2003:db8:1:0:214:1234:fe0b:3596/64 specify the ipv6 address to use as the gateway inside the container. The address is in format x::y, eg. 2003:db8:1:0::1 Can also have the special value , which means to take the primary address from the bridge interface (as specified by the option) and use that as the gateway. is only available when using the and network types. add a configuration option to specify a script to be executed after creating and configuring the network used from the host side. The following arguments are passed to the script: container name and config section name (net) Additional arguments depend on the config section employing a script hook; the following are used by the network system: execution context (up), network type (empty/veth/macvlan/phys), Depending on the network type, other arguments may be passed: veth/macvlan/phys. And finally (host-sided) device name. Standard output from the script is logged at debug level. Standard error is not logged, but can be captured by the hook redirecting its standard error to standard output. add a configuration option to specify a script to be executed before destroying the network used from the host side. The following arguments are passed to the script: container name and config section name (net) Additional arguments depend on the config section employing a script hook; the following are used by the network system: execution context (down), network type (empty/veth/macvlan/phys), Depending on the network type, other arguments may be passed: veth/macvlan/phys. And finally (host-sided) device name. Standard output from the script is logged at debug level. Standard error is not logged, but can be captured by the hook redirecting its standard error to standard output. New pseudo tty instance (devpts) For stricter isolation the container can have its own private instance of the pseudo tty. If set, the container will have a new pseudo tty instance, making this private to it. The value specifies the maximum number of pseudo ttys allowed for a pts instance (this limitation is not implemented yet). Container system console If the container is configured with a root filesystem and the inittab file is setup to use the console, you may want to specify where the output of this console goes. Specify a path to a file where the console output will be written. Specify a path to a device to which the console will be attached. The keyword 'none' will simply disable the console. This is dangerous once if have a rootfs with a console device file where the application can write, the messages will fall in the host. Console through the ttys This option is useful if the container is configured with a root filesystem and the inittab file is setup to launch a getty on the ttys. The option specifies the number of ttys to be available for the container. The number of gettys in the inittab file of the container should not be greater than the number of ttys specified in this option, otherwise the excess getty sessions will die and respawn indefinitely giving annoying messages on the console or in /var/log/messages. Specify the number of tty to make available to the container. Console devices location LXC consoles are provided through Unix98 PTYs created on the host and bind-mounted over the expected devices in the container. By default, they are bind-mounted over /dev/console and /dev/ttyN. This can prevent package upgrades in the guest. Therefore you can specify a directory location (under /dev under which LXC will create the files and bind-mount over them. These will then be symbolically linked to /dev/console and /dev/ttyN. A package upgrade can then succeed as it is able to remove and replace the symbolic links. Specify a directory under /dev under which to create the container console devices. /dev directory By default, lxc creates a few symbolic links (fd,stdin,stdout,stderr) in the container's /dev directory but does not automatically create device node entries. This allows the container's /dev to be set up as needed in the container rootfs. If lxc.autodev is set to 1, then after mounting the container's rootfs LXC will mount a fresh tmpfs under /dev (limited to 500k) and fill in a minimal set of initial devices. This is generally required when starting a container containing a "systemd" based "init" but may be optional at other times. Additional devices in the containers /dev directory may be created through the use of the hook. Set this to 0 to stop LXC from mounting and populating a minimal /dev when starting the container. Enable kmsg symlink Enable creating /dev/kmsg as symlink to /dev/console. This defaults to 0. Set this to 1 to enable /dev/kmsg symlinking. Mount points The mount points section specifies the different places to be mounted. These mount points will be private to the container and won't be visible by the processes running outside of the container. This is useful to mount /etc, /var or /home for examples. NOTE - LXC will generally ensure that mount targets and relative bind-mount sources are properly confined under the container root, to avoid attacks involving over-mounting host directories and files. (Symbolic links in absolute mount sources are ignored) However, if the container configuration first mounts a directory which is under the control of the container user, such as /home/joe, into the container at some path, and then mounts under path, then a TOCTTOU attack would be possible where the container user modifies a symbolic link under his home directory at just the right time. specify a file location in the fstab format, containing the mount information. The mount target location can and in most cases should be a relative path, which will become relative to the mounted container root. For instance, proc proc proc nodev,noexec,nosuid 0 0 Will mount a proc filesystem under the container's /proc, regardless of where the root filesystem comes from. This is resilient to block device backed filesystems as well as container cloning. Note that when mounting a filesystem from an image file or block device the third field (fs_vfstype) cannot be auto as with mount 8 but must be explicitly specified. specify a mount point corresponding to a line in the fstab format. Moreover lxc add two options to mount. don't fail if mount does not work. or to create dir (or file) when the point will be mounted. specify which standard kernel file systems should be automatically mounted. This may dramatically simplify the configuration. The file systems are: (or ): mount /proc as read-write, but remount /proc/sys and /proc/sysrq-trigger read-only for security / container isolation purposes. : mount /proc as read-write (or ): mount /sys as read-only but with /sys/devices/virtual/net writable. : mount /sys as read-only for security / container isolation purposes. : mount /sys as read-write : mount a tmpfs to /sys/fs/cgroup, create directories for all hierarchies to which the container is added, create subdirectories there with the name of the cgroup, and bind-mount the container's own cgroup into that directory. The container will be able to write to its own cgroup directory, but not the parents, since they will be remounted read-only. : similar to , but everything will be mounted read-only. : similar to , but everything will be mounted read-write. Note that the paths leading up to the container's own cgroup will be writable, but will not be a cgroup filesystem but just part of the tmpfs of /sys/fs/cgroup (without specifier): defaults to if the container retains the CAP_SYS_ADMIN capability, otherwise. : mount a tmpfs to /sys/fs/cgroup, create directories for all hierarchies to which the container is added, bind-mount the hierarchies from the host to the container and make everything read-only except the container's own cgroup. Note that compared to , where all paths leading up to the container's own cgroup are just simple directories in the underlying tmpfs, here /sys/fs/cgroup/$hierarchy will contain the host's full cgroup hierarchy, albeit read-only outside the container's own cgroup. This may leak quite a bit of information into the container. : similar to , but everything will be mounted read-only. : similar to , but everything will be mounted read-write. Note that in this case, the container may escape its own cgroup. (Note also that if the container has CAP_SYS_ADMIN support and can mount the cgroup filesystem itself, it may do so anyway.) (without specifier): defaults to if the container retains the CAP_SYS_ADMIN capability, otherwise. If cgroup namespaces are enabled, then any auto-mounting request will be ignored, since the container can mount the filesystems itself, and automounting can confuse the container init. Note that if automatic mounting of the cgroup filesystem is enabled, the tmpfs under /sys/fs/cgroup will always be mounted read-write (but for the and cases, the individual hierarchies, /sys/fs/cgroup/$hierarchy, will be read-only). This is in order to work around a quirk in Ubuntu's mountall 8 command that will cause containers to wait for user input at boot if /sys/fs/cgroup is mounted read-only and the container can't remount it read-write due to a lack of CAP_SYS_ADMIN. Examples: lxc.mount.auto = proc sys cgroup lxc.mount.auto = proc:rw sys:rw cgroup-full:rw Root file system The root file system of the container can be different than that of the host system. specify the root file system for the container. It can be an image file, a directory or a block device. If not specified, the container shares its root file system with the host. For directory or simple block-device backed containers, a pathname can be used. If the rootfs is backed by a nbd device, then nbd:file:1 specifies that file should be attached to a nbd device, and partition 1 should be mounted as the rootfs. nbd:file specifies that the nbd device itself should be mounted. overlayfs:/lower:/upper specifies that the rootfs should be an overlay with /upper being mounted read-write over a read-only mount of /lower. aufs:/lower:/upper does the same using aufs in place of overlayfs. For both overlayfs and aufs multiple /lower directories can be specified. loop:/file tells lxc to attach /file to a loop device and mount the loop device. where to recursively bind before pivoting. This is to ensure success of the pivot_root 8 syscall. Any directory suffices, the default should generally work. extra mount options to use when mounting the rootfs. specify the rootfs backend type to use, for instance 'dir' or 'zfs'. While this can be guessed by lxc at container startup, doing so takes time. Specifying it here avoids extra processing. Control group The control group section contains the configuration for the different subsystem. lxc does not check the correctness of the subsystem name. This has the disadvantage of not detecting configuration errors until the container is started, but has the advantage of permitting any future subsystem. specify the control group value to be set. The subsystem name is the literal name of the control group subsystem. The permitted names and the syntax of their values is not dictated by LXC, instead it depends on the features of the Linux kernel running at the time the container is started, eg. Capabilities The capabilities can be dropped in the container if this one is run as root. Specify the capability to be dropped in the container. A single line defining several capabilities with a space separation is allowed. The format is the lower case of the capability definition without the "CAP_" prefix, eg. CAP_SYS_MODULE should be specified as sys_module. See capabilities 7 . If used with no value, lxc will clear any drop capabilities specified up to this point. Specify the capability to be kept in the container. All other capabilities will be dropped. When a special value of "none" is encountered, lxc will clear any keep capabilities specified up to this point. A value of "none" alone can be used to drop all capabilities. Apparmor profile If lxc was compiled and installed with apparmor support, and the host system has apparmor enabled, then the apparmor profile under which the container should be run can be specified in the container configuration. The default is lxc-container-default-cgns if the host kernel is cgroup namespace aware, or lxc-container-default othewise. Specify the apparmor profile under which the container should be run. To specify that the container should be unconfined, use lxc.aa_profile = unconfined If the apparmor profile should remain unchanged (i.e. if you are nesting containers and are already confined), then use lxc.aa_profile = unchanged Apparmor profiles are pathname based. Therefore many file restrictions require mount restrictions to be effective against a determined attacker. However, these mount restrictions are not yet implemented in the upstream kernel. Without the mount restrictions, the apparmor profiles still protect against accidental damager. If this flag is 0 (default), then the container will not be started if the kernel lacks the apparmor mount features, so that a regression after a kernel upgrade will be detected. To start the container under partial apparmor protection, set this flag to 1. SELinux context If lxc was compiled and installed with SELinux support, and the host system has SELinux enabled, then the SELinux context under which the container should be run can be specified in the container configuration. The default is unconfined_t, which means that lxc will not attempt to change contexts. See @DATADIR@/lxc/selinux/lxc.te for an example policy and more information. Specify the SELinux context under which the container should be run or unconfined_t. For example lxc.se_context = system_u:system_r:lxc_t:s0:c22 Seccomp configuration A container can be started with a reduced set of available system calls by loading a seccomp profile at startup. The seccomp configuration file must begin with a version number on the first line, a policy type on the second line, followed by the configuration. Versions 1 and 2 are currently supported. In version 1, the policy is a simple whitelist. The second line therefore must read "whitelist", with the rest of the file containing one (numeric) sycall number per line. Each syscall number is whitelisted, while every unlisted number is blacklisted for use in the container In version 2, the policy may be blacklist or whitelist, supports per-rule and per-policy default actions, and supports per-architecture system call resolution from textual names. An example blacklist policy, in which all system calls are allowed except for mknod, which will simply do nothing and return 0 (success), looks like: 2 blacklist mknod errno 0 Specify a file containing the seccomp configuration to load before the container starts. UID mappings A container can be started in a private user namespace with user and group id mappings. For instance, you can map userid 0 in the container to userid 200000 on the host. The root user in the container will be privileged in the container, but unprivileged on the host. Normally a system container will want a range of ids, so you would map, for instance, user and group ids 0 through 20,000 in the container to the ids 200,000 through 220,000. Four values must be provided. First a character, either 'u', or 'g', to specify whether user or group ids are being mapped. Next is the first userid as seen in the user namespace of the container. Next is the userid as seen on the host. Finally, a range indicating the number of consecutive ids to map. Container hooks Container hooks are programs or scripts which can be executed at various times in a container's lifetime. When a container hook is executed, information is passed both as command line arguments and through environment variables. The arguments are: Container name. Section (always 'lxc'). The hook type (i.e. 'clone' or 'pre-mount'). Additional arguments. In the case of the clone hook, any extra arguments passed to lxc-clone will appear as further arguments to the hook. In the case of the stop hook, paths to filedescriptors for each of the container's namespaces along with their types are passed. The following environment variables are set: LXC_NAME: is the container's name. LXC_ROOTFS_MOUNT: the path to the mounted root filesystem. LXC_CONFIG_FILE: the path to the container configuration file. LXC_SRC_NAME: in the case of the clone hook, this is the original container's name. LXC_ROOTFS_PATH: this is the lxc.rootfs entry for the container. Note this is likely not where the mounted rootfs is to be found, use LXC_ROOTFS_MOUNT for that. Standard output from the hooks is logged at debug level. Standard error is not logged, but can be captured by the hook redirecting its standard error to standard output. A hook to be run in the host's namespace before the container ttys, consoles, or mounts are up. A hook to be run in the container's fs namespace but before the rootfs has been set up. This allows for manipulation of the rootfs, i.e. to mount an encrypted filesystem. Mounts done in this hook will not be reflected on the host (apart from mounts propagation), so they will be automatically cleaned up when the container shuts down. A hook to be run in the container's namespace after mounting has been done, but before the pivot_root. A hook to be run in the container's namespace after mounting has been done and after any mount hooks have run, but before the pivot_root, if == 1. The purpose of this hook is to assist in populating the /dev directory of the container when using the autodev option for systemd based containers. The container's /dev directory is relative to the ${} environment variable available when the hook is run. A hook to be run in the container's namespace immediately before executing the container's init. This requires the program to be available in the container. A hook to be run in the host's namespace with references to the container's namespaces after the container has been shut down. For each namespace an extra argument is passed to the hook containing the namespace's type and a filename that can be used to obtain a file descriptor to the corresponding namespace, separated by a colon. The type is the name as it would appear in the /proc/PID/ns directory. For instance for the mount namespace the argument usually looks like mnt:/proc/PID/fd/12. A hook to be run in the host's namespace after the container has been shut down. A hook to be run when the container is cloned to a new one. See lxc-clone 1 for more information. A hook to be run when the container is destroyed. Container hooks Environment Variables A number of environment variables are made available to the startup hooks to provide configuration information and assist in the functioning of the hooks. Not all variables are valid in all contexts. In particular, all paths are relative to the host system and, as such, not valid during the hook. The LXC name of the container. Useful for logging messages in common log environments. [] Host relative path to the container configuration file. This gives the container to reference the original, top level, configuration file for the container in order to locate any additional configuration information not otherwise made available. [] The path to the console output of the container if not NULL. [] [] The path to the console log output of the container if not NULL. [] The mount location to which the container is initially bound. This will be the host relative path to the container rootfs for the container instance being started and is where changes should be made for that instance. [] The host relative path to the container root which has been mounted to the rootfs.mount location. [] Only for the clone hook. Is set to the original container name. Only for the stop hook. Is set to "stop" for a container shutdown or "reboot" for a container reboot. If unset, then this version of lxc is not aware of cgroup namespaces. If set, it will be set to 1, and lxc is aware of cgroup namespaces. Note this does not guarantee that cgroup namespaces are enabled in the kernel. This is used by the lxcfs mount hook. Logging Logging can be configured on a per-container basis. By default, depending upon how the lxc package was compiled, container startup is logged only at the ERROR level, and logged to a file named after the container (with '.log' appended) either under the container path, or under @LOGPATH@. Both the default log level and the log file can be specified in the container configuration file, overriding the default behavior. Note that the configuration file entries can in turn be overridden by the command line options to lxc-start. The level at which to log. The log level is an integer in the range of 0..8 inclusive, where a lower number means more verbose debugging. In particular 0 = trace, 1 = debug, 2 = info, 3 = notice, 4 = warn, 5 = error, 6 = critical, 7 = alert, and 8 = fatal. If unspecified, the level defaults to 5 (error), so that only errors and above are logged. Note that when a script (such as either a hook script or a network interface up or down script) is called, the script's standard output is logged at level 1, debug. The file to which logging info should be written. Autostart The autostart options support marking which containers should be auto-started and in what order. These options may be used by LXC tools directly or by external tooling provided by the distributions. Whether the container should be auto-started. Valid values are 0 (off) and 1 (on). How long to wait (in seconds) after the container is started before starting the next one. An integer used to sort the containers when auto-starting a series of containers at once. If not zero the mount namespace will be unshared from the host before initializing the container (before running any pre-start hooks). This requires the CAP_SYS_ADMIN capability at startup. Default is 0. A multi-value key (can be used multiple times) to put the container in a container group. Those groups can then be used (amongst other things) to start a series of related containers. Autostart and System Boot Each container can be part of any number of groups or no group at all. Two groups are special. One is the NULL group, i.e. the container does not belong to any group. The other group is the "onboot" group. When the system boots with the LXC service enabled, it will first attempt to boot any containers with lxc.start.auto == 1 that is a member of the "onboot" group. The startup will be in order of lxc.start.order. If an lxc.start.delay has been specified, that delay will be honored before attempting to start the next container to give the current container time to begin initialization and reduce overloading the host system. After starting the members of the "onboot" group, the LXC system will proceed to boot containers with lxc.start.auto == 1 which are not members of any group (the NULL group) and proceed as with the onboot group. Container Environment If you want to pass environment variables into the container (that is, environment variables which will be available to init and all of its descendents), you can use lxc.environment parameters to do so. Be careful that you do not pass in anything sensitive; any process in the container which doesn't have its environment scrubbed will have these variables available to it, and environment variables are always available via /proc/PID/environ. This configuration parameter can be specified multiple times; once for each environment variable you wish to configure. Specify an environment variable to pass into the container. Example: lxc.environment = APP_ENV=production lxc.environment = SYSLOG_SERVER=192.0.2.42 Examples In addition to the few examples given below, you will find some other examples of configuration file in @DOCDIR@/examples Network This configuration sets up a container to use a veth pair device with one side plugged to a bridge br0 (which has been configured before on the system by the administrator).

It lets the user start, shutdown, kill, restart containers in the right order, waiting the right time. Supports filtering by lxc.group or just run against all defined containers. It can also be used by external tools in list mode where no action will be performed and the list of affected containers (and if relevant, delays) will be shown. The -r, -s and -k options specify the action to perform. If none is specified, then the containers will be started. -a and -g are used to specify which containers will be affected. By default only containers without a lxc.group set will be affected. -t TIMEOUT specifies the maximum amount of time to wait for the container to complete the shutdown or reboot. Options Request a reboot of the container. Request a clean shutdown. If a -t timeout greater than 0 is given and the container has not shut down within this period, it will be killed as with the -k kill option. Rather than requesting a clean shutdown of the container, explicitly kill all tasks in the container. Rather than performing the action, just print the container name and wait delays until starting the next container. Wait TIMEOUT seconds before hard-stopping the container. Comma separated list of groups to select (defaults to those without a lxc.group - the NULL group). This option may be specified multiple times and the arguments concatenated. The NULL or empty group may be specified as a leading comma, trailing comma, embedded double comma, or empty argument where the NULL group should be processed. Groups are processed in the order specified on the command line. Multiple invocations of the -g option may be freely intermixed with the comma separated lists and will be combined in specified order. Ignore lxc.group and select all auto-started containers. Ignore the lxc.start.auto flag. Combined with -a, will select all containers on the system. Autostart and System Boot The lxc-autostart command is used as part of the LXC system service, when enabled to run on host system at bootup and at shutdown. It's used to select which containers to start in what order and how much to delay between each startup when the host system boots. Each container can be part of any number of groups or no group at all. Two groups are special. One is the NULL group, i.e. the container does not belong to any group. The other group is the "onboot" group. When the system boots with the LXC service enabled, it will first attempt to boot any containers with lxc.start.auto == 1 that is a member of the "onboot" group. The startup will be in order of lxc.start.order. If an lxc.start.delay has been specified, that delay will be honored before attempting to start the next container to give the current container time to begin initialization and reduce overloading the host system. After starting the members of the "onboot" group, the LXC system will proceed to boot containers with lxc.start.auto == 1 which are not members of any group (the NULL group) and proceed as with the onboot group.

The container has to be running already. If no command is specified, the current default shell of the user running lxc-attach will be looked up inside the container and executed. This will fail if no such user exists inside the container or the container does not have a working nsswitch mechanism. Previous versions of lxc-attach simply attached to the specified namespaces of a container and ran a shell or the specified command without first allocating a pseudo terminal. This made them vulnerable to input faking via a TIOCSTI ioctl call after switching between userspace execution contexts with different privilege levels. Newer versions of lxc-attach will try to allocate a pseudo terminal master/slave pair on the host and attach any standard file descriptors which refer to a terminal to the slave side of the pseudo terminal before executing a shell or command. Note, that if none of the standard file descriptors refer to a terminal lxc-attach will not try to allocate a pseudo terminal. Instead it will simply attach to the containers namespaces and run a shell or the specified command. Options Specify the configuration file to configure the virtualization and isolation functionalities for the container. This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create). Specify the architecture which the kernel should appear to be running as to the command executed. This option will accept the same settings as the option in container configuration files, see lxc.conf 5 . By default, the current archictecture of the running container will be used. Do not drop privileges when running command inside the container. If this option is specified, the new process will not be added to the container's cgroup(s) and it will not drop its capabilities before executing. You may specify privileges, in case you do not want to elevate all of them, as a pipe-separated list, e.g. CGROUP|LSM. Allowed values are CGROUP, CAP and LSM representing cgroup, capabilities and restriction privileges respectively. (The pipe symbol needs to be escaped, e.g. CGROUP\|LSM or quoted, e.g. "CGROUP|LSM".) Warning: This may leak privileges into the container if the command starts subprocesses that remain active after the main process that was attached is terminated. The (re-)starting of daemons inside the container is problematic, especially if the daemon starts a lot of subprocesses such as cron or sshd. Use with great care. Specify the namespaces to attach to, as a pipe-separated list, e.g. NETWORK|IPC. Allowed values are MOUNT, PID, UTSNAME, IPC, USER and NETWORK. This allows one to change the context of the process to e.g. the network namespace of the container while retaining the other namespaces as those of the host. (The pipe symbol needs to be escaped, e.g. MOUNT\|PID or quoted, e.g. "MOUNT|PID".) Important: This option implies . When using and the mount namespace is not included, this flag will cause lxc-attach to remount /proc and /sys to reflect the current other namespace contexts. Please see the Notes section for more details. This option will be ignored if one tries to attach to the mount namespace anyway. Keep the current environment for attached programs. This is the current default behaviour (as of version 0.9), but is is likely to change in the future, since this may leak undesirable information into the container. If you rely on the environment being available for the attached program, please use this option to be future-proof. In addition to current environment variables, container=lxc will be set. Clear the environment before attaching, so no undesired environment variables leak into the container. The variable container=lxc will be the only environment with which the attached program starts. Specify a file where the output of lxc-attach will be logged. Important: When a standard file descriptor does not refer to a pty output produced on it will not be logged. Set an additional environment variable that is seen by the attached program in the container. It is specified in the form of "VAR=VALUE", and can be specified multiple times. Keep a specified environment variable. It can only be specified in conjunction with --clear-env, and can be specified multiple times. &commonoptions; Examples To spawn a new shell running inside an existing container, use lxc-attach -n container To restart the cron service of a running Debian container, use lxc-attach -n container -- /etc/init.d/cron restart To deactivate the network link eth1 of a running container that does not have the NET_ADMIN capability, use either the option to use increased capabilities, assuming the ip tool is installed: lxc-attach -n container -e -- /sbin/ip link delete eth1 Or, alternatively, use the to use the tools installed on the host outside the container: lxc-attach -n container -s NETWORK -- /sbin/ip link delete eth1 Compatibility Attaching completely (including the pid and mount namespaces) to a container requires a kernel of version 3.8 or higher, or a patched kernel, please see the lxc website for details. lxc-attach will fail in that case if used with an unpatched kernel of version 3.7 and prior. Nevertheless, it will succeed on an unpatched kernel of version 3.0 or higher if the option is used to restrict the namespaces that the process is to be attached to to one or more of NETWORK, IPC and UTSNAME. Attaching to user namespaces is supported by kernel 3.8 or higher with enabling user namespace. Notes The Linux /proc and /sys filesystems contain information about some quantities that are affected by namespaces, such as the directories named after process ids in /proc or the network interface information in /sys/class/net. The namespace of the process mounting the pseudo-filesystems determines what information is shown, not the namespace of the process accessing /proc or /sys. If one uses the option to only attach to the pid namespace of a container, but not its mount namespace (which will contain the /proc of the container and not the host), the contents of will reflect that of the host and not the container. Analogously, the same issue occurs when reading the contents of /sys/class/net and attaching to just the network namespace. To work around this problem, the flag provides the option to remount /proc and /sys in order for them to reflect the network/pid namespace context of the attached process. In order not to interfere with the host's actual filesystem, the mount namespace will be unshared (like lxc-unshare does) before this is done, essentially giving the process a new mount namespace, which is identical to the hosts's mount namespace except for the /proc and /sys filesystems. Previous versions of lxc-attach suffered a bug whereby a user could attach to a containers namespace without being placed in a writeable cgroup for some critical subsystems. Newer versions of lxc-attach will check whether a user is in a writeable cgroup for those critical subsystems. lxc-attach might thus fail unexpectedly for some users (E.g. on systems where an unprivileged user is not placed in a writeable cgroup in critical subsystems on login.). However, this behavior is correct and more secure. Security The and options should be used with care, as it may break the isolation of the containers if used improperly. &seealso; Author Daniel Lezcano daniel.lezcano@free.fr lxc-2.0.7/doc/lxc-clone.sgml.in0000644061062106075000000002170213041440472013162 00000000000000 ]> @LXC_GENERATE_DATE@ lxc-clone 1 lxc-clone clone a new container from an existing one. lxc-clone -s -K -M -H -B backingstore -L fssize -p lxcpath -P newlxcpath -R -o orig -n new -- hook arguments lxc-clone -s -K -M -H -B backingstore -L fssize -p lxcpath -P newlxcpath -R orig new -- hook arguments Description lxc-clone Creates a new container as a clone of an existing container. Two types of clones are supported: copy and snapshot. A copy clone copies the root filessytem from the original container to the new. A snapshot filesystem uses the backing store's snapshot functionality to create a very small copy-on-write snapshot of the original container. Snapshot clones require the new container backing store to support snapshotting. Currently this includes only aufs, btrfs, lvm, overlayfs and zfs. LVM devices do not support snapshots of snapshots. The backing store of the new container will be the same type as the original container, with one exception, overlay containers. aufs and overlayfs snapshots can be created of directory backed containers. This can be requested by using (for overlayfs) the -B overlayfs arguments. The names of the original and new container can be given (in that order) after all options, or can be specified with the -o and -n options, respectively. Options The new container's rootfs will be a snapshot of the original. This option can be specified when the backing store is LVM, btrfs or zfs, and must be specified when you want to snapshot using aufs or overlayfs. Do not change the hostname of the container (in the root filesystem). Use the same MAC address as the original container, rather than generating a new random one. Copy all mount hooks into the new container's directory, and update any lxcpaths and container names as needed. In the case of a block device backed container, a size for the new block device. By default, the new device will be made the same size as the original. The lxcpath of the original container. By default, the system wide configured lxcpath will be used. The lxcpath for the new container. By default the same lxcpath as the original will be used. Note that with btrfs snapshots, changing lxcpaths may not be possible, as subvolume snapshots must be in the same btrfs filesystem. Select a different backing store for the new container. By default the same as the original container's is used. Note that currently changing the backingstore is only supported for aufs and overlayfs snapshots of directory backed containers. Valid backing stores include dir (directory), aufs, btrfs, lvm, zfs, loop and overlayfs. Rename an existing container. orig is renamed new. The name of the original container to clone. The name of the new container to create. Clone hook If the container being cloned has one or more lxc.hook.clone specified, then the specified hooks will be called for the new container. The first 3 arguments passed to the clone hook will be the container name, a section ('lxc'), and the hook type ('clone'). Extra arguments passed lxc-clone will be passed to the hook program starting at argument 4. The LXC_ROOTFS_MOUNT environment variable gives the path under which the container's root filesystem is mounted. The configuration file pathname is stored in LXC_CONFIG_FILE, the new container name in LXC_NAME, the old container name in LXC_SRC_NAME, and the path or device on which the rootfs is located is in LXC_ROOTFS_PATH.

Snapshots are stored as snapshotted containers under the container's configuration path. For instance, if the container's configuration path is /var/lib/lxc and the container is c1, then the first snapshot will be stored as container snap0 under the path /var/lib/lxc/c1/snaps. If /var/lib/lxcsnaps, as used by LXC 1.0, already exists, then it will continue to be used. Options Associate the comment in comment_file with the newly created snapshot. Destroy the named snapshot. If the named snapshot is ALL, then all snapshots will be destroyed. List existing snapshots. Show snapshot comments in the snapshots listings. Restore the named snapshot, meaning a full new container is created which is a copy of the snapshot. When restoring a snapshot, the last optional argument if not given explicitly via --newname is the name to use for the restored container. If the newname is identical to the original name of the container, then the original container will be destroyed and the restored container will take its place. Note that deleting the original snapshot is not possible in the case of aufs, overlayfs or zfs backed snapshots. &commonoptions; &seealso; Author Serge Hallyn serge.hallyn@ubuntu.com lxc-2.0.7/doc/lxc-create.sgml.in0000644061062106075000000001745413041440472013336 00000000000000 ]> @LXC_GENERATE_DATE@ lxc-create 1 lxc-create creates a container lxc-create -n name -f config_file -t template -B backingstore -- template-options Description lxc-create creates a system object where is stored the configuration information and where can be stored user information. The identifier name is used to specify the container to be used with the different lxc commands. The object is a directory created in @LXCPATH@ and identified by its name. The object is the definition of the different resources an application can use or can see. The more the configuration file contains information, the more the container is isolated and the more the application is jailed. If the configuration file config_file is not specified, the container will be created with the default isolation: processes, sysv ipc and mount points. Options Specify the configuration file to configure the virtualization and isolation functionalities for the container. 'template' is the short name of an existing 'lxc-template' script that is called by lxc-create, eg. busybox, debian, fedora, ubuntu or sshd. Refer to the examples in @LXCTEMPLATEDIR@ for details of the expected script structure. Alternatively, the full path to an executable template script can also be passed as a parameter. "none" can be used to force lxc-create to skip rootfs creation. 'backingstore' is one of 'dir', 'lvm', 'loop', 'btrfs', 'zfs', 'rbd', or 'best'. The default is 'dir', meaning that the container root filesystem will be a directory under @LXCPATH@/container/rootfs. This backing store type allows the optional --dir ROOTFS to be specified, meaning that the container rootfs should be placed under the specified path, rather than the default. (The 'none' backingstore type is an alias for 'dir'.) If 'btrfs' is specified, then the target filesystem must be btrfs, and the container rootfs will be created as a new subvolume. This allows snapshotted clones to be created, but also causes rsync --one-filesystem to treat it as a separate filesystem. If backingstore is 'lvm', then an lvm block device will be used and the following further options are available: --lvname lvname1 will create an LV named lvname1 rather than the default, which is the container name. --vgname vgname1 will create the LV in volume group vgname1 rather than the default, lxc. --thinpool thinpool1 will create the LV as a thin-provisioned volume in the pool named thinpool1 rather than the default, lxc. --fstype FSTYPE will create an FSTYPE filesystem on the LV, rather than the default, which is ext4. --fssize SIZE will create a LV (and filesystem) of size SIZE rather than the default, which is 1G. If backingstore is 'loop', you can use --fstype FSTYPE and --fssize SIZE as 'lvm'. The default values for these options are the same as 'lvm'. If backingstore is 'rbd', then you will need to have a valid configuration in ceph.conf and a ceph.client.admin.keyring defined. You can specify the following options : --rbdname RBDNAME will create a blockdevice named RBDNAME rather than the default, which is the container name. --rbdpool POOL will create the blockdevice in the pool named POOL, rather than the default, which is 'lxc'. If backingstore is 'best', then lxc will try, in order, btrfs, zfs, lvm, and finally a directory backing store. This will pass template-options to the template as arguments. To see the list of options supported by the template, you can run lxc-create -t TEMPLATE -h. &commonoptions; Diagnostic The container already exists As the message mention it, you try to create a container but there is a container with the same name.

It can either be the path to a device under /dev or a network interface name. Name for the device within the container. Examples lxc-device -n p1 add /dev/video0 Creates a /dev/video0 device in container p1 based on the matching device on the host. lxc-device -n p1 add eth0 eth1 Moves eth0 from the host as eth1 in p1. &seealso; Author Stéphane Graber stgraber@ubuntu.com lxc-2.0.7/doc/common_options.sgml.in0000644061062106075000000000756713041440472014356 00000000000000 Common Options These options are common to most of lxc commands. Print a longer usage message than normal. Give the usage message mute on Use an alternate container path. The default is @LXCPATH@. Output to an alternate log FILE. The default is no log. Set log priority to LEVEL. The default log priority is ERROR. Possible values are : FATAL, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG. Note that this option is setting the priority of the events log in the alternate log file. It do not have effect on the ERROR events log on stderr. Use container identifier NAME. The container identifier format is an alphanumeric string. Specify the configuration file to configure the virtualization and isolation functionalities for the container. This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create).

If no value is specified, the current value of the state-object is displayed; otherwise it is set. Note that lxc-cgroup does not check that the state-object is valid for the running kernel, or that the corresponding subsystem is contained in any mounted cgroup hierarchy.

It replaces lxc-clone and lxc-start-ephemeral. lxc-copy creates copies of existing containers. Copies can be complete clones of the original container. In this case the whole root filesystem of the container is simply copied to the new container. Or they can be snapshots, i.e. small copy-on-write copies of the original container. In this case the specified backing storage for the copy must support snapshots. This currently includes aufs, btrfs, lvm (lvm devices do not support snapshots of snapshots.), overlay, and zfs. The copy's backing storage will be of the same type as the original container. aufs or overlayfs snapshots of directory backed containers are exempted from this rule. When the -e flag is specified an ephemeral snapshot of the original container is created and started. Ephemeral containers will have lxc.ephemeral = 1 set in their config file and will be destroyed on shutdown. When -e is used in combination with -D a non-ephemeral snapshot of the original container is created and started. When -e is specified and no newname is given via -N a random name for the snapshot will be chosen. Containers created and started with -e can have custom mounts. These are specified with the -m flag. Currently three types of mounts are supported: aufs, bind, and overlay. Mount types are specified as suboptions to the -m flag and can be specified multiple times separated by commas. aufs and overlay mounts are currently specified in the format -m overlay=/src:/dest. When no destination dest is specified dest will be identical to src. Read-only bind mounts are specified -m bind=/src:/dest:ro and read-write bind mounts -m bind=/src:/dest:rw. Read-write bind mounts are the default and rw can be missing when a read-write mount is wanted. When dest is missing dest will be identical to src. An example for multiple mounts would be -m bind=/src1:/dest1:ro,bind=/src2:ro,overlay=/src3:/dest3. The mounts, their options, and formats supported via the -m flag are subject to change. Options The name for the copy. The path for the copy. Rename the original container. Create a snapshot of the original container. The backing storage for the copy must support snapshots. This currently includes aufs, btrfs, lvm, overlay, and zfs. Run the snapshot in the foreground. The snapshots console will be attached to the current tty. (This option can only be specified in conjunction with -e.) Run the snapshot as a daemon (This is the default mode for ephemeral containers.). As the container has no more tty, if an error occurs nothing will be displayed, the log file can be used to check the error. (This option can only be specified in conjunction with -e.) Specify a mount for a snapshot The opts argument for the mount type can by of type {aufs, bind, overlay}. For example (This option can currently only be specified in conjunction with -e.). Specify the backing storage type to be used for the copy where 'backingstorage' is of type 'aufs', 'btrfs', 'dir', 'lvm', 'loop', 'overlay', or 'zfs'. Specify the size for an 'lvm' filesystem. When this option is specified with -e a non-ephemeral container is created and started. When this option is specified the hostname of the original container will be kept for the copy. When this option is specified the MAC address of the original container will be kept for the copy. Copy hook If the container being copied has one or more lxc.hook.clone specified, then the specified hooks will be called for the new container. The first 3 arguments passed to the clone hook will be the container name, a section ('lxc'), and the hook type ('clone'). Extra arguments passed to lxc-copy will be passed to the hook program starting at argument 4. The LXC_ROOTFS_MOUNT environment variable gives the path under which the container's root filesystem is mounted. The configuration file pathname is stored in LXC_CONFIG_FILE, the new container name in LXC_NAME, the old container name in LXC_SRC_NAME, and the path or device on which the rootfs is located is in LXC_ROOTFS_PATH. &commonoptions; &seealso; Author Christian Brauner christian.brauner@mailbox.org lxc-2.0.7/doc/lxc-execute.sgml.in0000644061062106075000000001230613041440472013524 00000000000000 ]> @LXC_GENERATE_DATE@ lxc-execute 1 lxc-execute run an application inside a container. lxc-execute -n name -f config_file -s KEY=VAL -- command Description lxc-execute runs the specified command inside the container specified by name. It will setup the container according to the configuration previously defined with the lxc-create command or with the configuration file parameter. If no configuration is defined, the default isolation is used. This command is mainly used when you want to quickly launch an application in an isolated environment. lxc-execute command will run the specified command into the container via an intermediate process, lxc-init. This lxc-init after launching the specified command, will wait for its end and all other reparented processes. (to support daemons in the container). In other words, in the container, lxc-init has the pid 1 and the first process of the application has the pid 2. The above lxc-init is designed to forward received signals to the started command. Options Specify the configuration file to configure the virtualization and isolation functionalities for the container. This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create). Assign value VAL to configuration variable KEY. This overrides any assignment done in config_file. Signal the end of options and disables further option processing. Any arguments after the -- are treated as arguments to command. This option is useful when you want specify options to command and don't want lxc-execute to interpret them. &commonoptions; Diagnostic The container is busy The specified container is already running an application. You should stop it before reuse this container or create a new one. &seealso; Author Daniel Lezcano daniel.lezcano@free.fr lxc-2.0.7/doc/lxc-stop.sgml.in0000644061062106075000000001357713041440472013062 00000000000000 ]> @LXC_GENERATE_DATE@ lxc-stop 1 lxc-stop stop the application running inside a container lxc-stop -n name -W -r -t timeout -k --nokill --nolock Description lxc-stop reboots, cleanly shuts down, or kills all the processes inside the container. By default, it will request a clean shutdown of the container by sending lxc.haltsignal (defaults to SIGPWR) to the container's init process, waiting up to 60 seconds for the container to exit, and then returning. If the container fails to cleanly exit in 60 seconds, it will be sent the lxc.stopsignal (defaults to SIGKILL) to force it to shut down. A request to reboot will send the lxc.rebootsignal (defaults to SIGINT) to the container's init process. The -W, -r, -k and --nokill options specify the action to perform. -W indicates that after performing the specified action, lxc-stop should immediately exit, while -t TIMEOUT specifies the maximum amount of time to wait for the container to complete the shutdown or reboot. Options Request a reboot of the container. Rather than requesting a clean shutdown of the container, explicitly kill all tasks in the container. This is the legacy lxc-stop behavior. Only request a clean shutdown, do not kill the container tasks if the clean shutdown fails. This option avoids the use of any of the API lxc locking, and should only be used if lxc-stop is hanging due to a bad system state. Simply perform the requestion action (reboot, shutdown, or hard kill) and exit. Wait TIMEOUT seconds before hard-stopping the container. Exit value 0 The container was successfully stopped. 1 An error occurred while stopping the container. 2 The specified container exists but was not running.

Options Original container name Name of the ephemeral container (defaults to a random suffix). Start the container in background and print the name and IP. This option can't be used if a command is passed. Directory to bind mount into container. Can be passed multiple times. The user to connect to the container as. Used when passing a command to lxc-start-ephemeral. Copy the provided SSH public key into the container. Specify the type of storage used by the container. Valid types are tmpfs or dir. Force a specific union file system. Can be one of: overlayfs aufs Use a persistent backend instead of tmpfs. With this option, you can lxc-stop and lxc-start the no longer so ephemeral container (it's still an overlay, but a persistent one). Immediately run the provided command in the container. This uses attach if the kernel supports it, otherwise uses ssh. This is incompatible with daemon mode.

Options Print a configuration key from the container. This option may be given multiple times to print out multiple key = value pairs. Just print the container's state. Just print the container's pid. Just print the container's IP addresses. Just print the container's statistics. Note that for performance reasons the kernel does not account kernel memory use unless a kernel memory limit is set. If a limit is not set, lxc-info will display kernel memory use as 0. A limit can be set by specifying lxc.cgroup.memory.kmem.limit_in_bytes = number in your container configuration file, see lxc.conf 5 . Print the container's statistics in raw, non-humanized form.

(파이프 기호는 CGROUP\|LSM처럼 \로 처리를 해주거나, "CGROUP|LSM"처럼 따옴표를 붙여야 한다.) 경고 : 만약 명령어가 attach된 메인프로세스가 종료된 후에, 실행 상태로 남아있는 서브프로세스를 시작하려고 한다면, 컨테이너 내부로 privilege 누수가 발생할 수 있다. 컨테이너 내에서 데몬을 시작(또는 재시작)하는 것은 문제가 될 수 있다. 특히 만약 데몬이 많은 서브프로세스 를 실행하는 경우라면, 예를 들어 cron와 sshd와 같은 경우는 문제가 될 수 있다. 충분한 주의를 기울여서 사용하여야 한다. 컨테이너의 어떤 네임스페이스와 연결할지 지정한다. NETWORK|IPC와 같이 파이프(|)로 구분된 리스트를 사용할 수 있다. 허용되는 값은 MOUNT, PID, UTSNAME, IPC, USER , NETWORK이다. 이를 사용하여, 컨테이너의 네트워크 네임스페이스를 사용하면서도 다른 네임스페이스는 호스트의 것을 그대로 사용하는 등의 조작이 가능하다. (파이프 기호는 MOUNT\|PID처럼 \로 처리를 해주거나, "MOUNT|PID"처럼 따옴표를 붙여야 한다.) 중요 : 이 옵션은 옵션을 포함하고 있다. 를 사용하여 마운트 네임스페이스를 포함하지 않았을 때, 이 플래그는 lxc-attach가 /proc와 /sys를 remount 하게 만든다. 이는 현재와 다른 네임스페이스 컨텍스트를 반영시키기 위함이다. 좀더 자세한 설명은 주의섹션을 참고하면 된다. 만약 마운트 네임스페이스에 연결하려고 한다면, 이 옵션은 무시된다. 현재의 환경변수를 실행할 프로그램에도 그대로 적용한다. 이것은 현재 기본 동작이지만 (버전 0.9에서), 향후에 충분히 바뀔 수도 있다. 왜냐하면, 이것은 컨테이너에게 바람직하지 않은 정보를 넘겨줄 수 있는 위험성이 있기 때문이다. 따라서 이 기능에 의존하고 있다면, 향후에도 이를 보장할 수 있도록 이 옵션을 사용하는 것이 좋다. 또한 현재 환경 변수와 더불어, container=lxc도 설정된다. 프로그램을 실행하기 전에 모든 환경변수를 지운다. 이를 통해 바람직하지 않은 환경변수 누출을 막을 수 있다. container=lxc 만이 프로그램이 실행되기 전에 설정되는 유일한 환경변수이다. lxc-attach의 출력을 기록할 파일을 지정한다. 중요: 표준 입출력 파일 디스크립터가 pty를 참조하지 않으면, 기록되지 않는다. 컨테이너 내에서 실행되는 프로그램이 볼 수 있는 환경변수를 추가한다. 이는 "VAR=VALUE" 형태로 지정되며, 여러 번 지정할 수 있다. \-\-clear-env와 함께 사용되며, 지정한 환경변수를 지우지 않고 그대로 유지한다. 여러 번 지정할 수 있다. &commonoptions; <!-- Examples -->예제 존재하는 컨테이너의 내부에 새로운 쉘을 실행한다. lxc-attach -n container 실행중인 Debian 컨테이너의 cron 서비스를 재시작한다. lxc-attach -n container -- /etc/init.d/cron restart NET_ADMIN capability없이 실행중인 컨테이너의 네트워크 링크 eth1을 비활성화하였다. 옵션을 사용하여 capability를 높였고, ip 툴이 설치되어있다고 가정하였다. lxc-attach -n container -e -- /sbin/ip link delete eth1 <!-- Compatibility -->호환성 (pid와 마운트 네임스페이스를 포함한) attach가 동작하기 위해서는 커널의 버전이 3.8 이상이거나 패치가 적용된 커널이어야 한다. 좀더 자세히 보려면 lxc 웹사이트를 참고하면 된다. lxc-attach는 패치되지 않은 커널 버전 3.7 이하면 실패된다. 그러나 를 사용하여 NETWORK, IPC, UTSNAME 네임스페이스 들만 지정한다면, 패치되지 않은 커널 3.0 이상에서도 성공적으로 동작한다. 사용자 네임스페이스와 연결되기 위해서는 커널 버전이 3.8 이상이어야 하고 사용자 네임스페이스가 활성화되어야 한다. <!-- Notes -->주의 리눅스의 /proc와 /sys 파일시스템은 네임스페이스의해 영향받는 몇가지 정보들을 포함하고 있다. 예를 들어 /proc의 프로세스 id로 된 폴더들이나 /sys/class/net의 네트워크 인터페이스 정보 등이다. pseudo 파일시스템을 마운트하는 프로세스의 네임스페이스가 여기에 어떤 정보를 표시할지 결정하는 것이지, /proc 또는 /sys에 접근하는 프로세스의 네임스페이스가 결정하는 것은 아니다. 를 사용하여 컨테이너의 pid 네임스페이스에만 attach 시키고 마운트 네임스페이스(컨테이너의 /proc는 포함하고, 호스트의 것은 포함하지 않는)는 attach 시키지 않는 경우, 의 내용은 컨테이너의 것이 아닌 호스트의 것이 된다. 네트워크 네임스페이스만을 연결하고 /sys/class/net의 내용을 읽을 때도 같은 현상이 있다. 이러한 문제를 해결하기 위해, 옵션이 제공된다. 해당 옵션은 attach되는 프로세스의 네트워크/pid 네임스페이스를 반영하기 위해 /proc와 /sys를 다시 마운트한다. 호스트의 실제 파일시스템에 방해가 되지 않기 위해 마운트 네임스페이스는 공유되지 않는다(lxc-unshare의 동작과 비슷). /proc와 /sys 파일시스템을 제외하고 호스트 마운트 네임스페이스와 동일한 새로운 마운트 네임스페이스가 주어지게 된다. 이전 버전의 lxc-attach는 몇몇 중요한 서브시스템에 쓰기가 가능한 cgroup 내에 없더라도, 사용자가 컨테이너의 네임스페이스에 연결할 수 있는 버그가 있었다. 새로운 버전의 lxc-attach는 현재 사용자가 몇몇 중요한 서브시스템에 쓰기 권한이 있는 cgroup에 속하는지 여부를 검사한다. 그러므로 lxc-attach는 사용자에 따라 실패하는 경우도 있다. (예를 들어, 로그인 시 비특권 사용자가 중요 서브시스템에 쓰기가 가능한 cgroup에 위치하지 않은 경우) 하지만 이러한 동작은 정확한 것이고 더 안전한 것이다. <!-- Security -->보안 와 옵션을 사용할때는 주의해야 한다. 잘못 사용하게 하면 컨테이너들 간의 고립(isolation)을 깨트릴 수 있다. &seealso; <!-- Author -->저자 Daniel Lezcano daniel.lezcano@free.fr lxc-2.0.7/doc/ko/lxc-info.sgml.in0000644061062106075000000001670313041440472013433 00000000000000 ]> @LXC_GENERATE_DATE@ lxc-info 1 lxc-info 컨테이너의 정보 조회 lxc-info -n name -c KEY -s -p -i -S -H <!-- Description -->설명 lxc-info는 컨테이너에 대한 정보를 조회하고 표시한다. <!-- Options --> 컨테이너의 설정값을 표시한다. 이 옵션은 1개 이상의 key = value 쌍을 표시할 수 있다. 컨테이너의 상태를 표시한다. 컨테이너의 pid를 표시한다.

'#' 문자를 앞에 붙여 주석임을 나타낼 수 있다. capability와 cgroup 옵션과 같은 리스트 옵션들은, 값을 지정하지 않고 사용할 수 있다. 값이 지정되지 않은 경우 이전에 설정했던 모든 값들을 지운다. <!-- Configuration -->설정 연관된 컨테이너들을 쉽게 관리하기 위해서, 컨테이너 설정파일은 다른 파일을 불러올 수 있다. 예를 들어서, 네트워크 설정은 여러 컨테이너들을 위해 공통된 하나의 파일로 정의될 수 있다. 그리고 만약 컨테이너들이 다른 호스트로 이동된다면, 해당 파일 하나만 수정하면 된다. include할 파일을 지정한다. include할 파일은 lxc 설정파일의 형식에 부합하여야 한다. <!-- Architecture -->아키텍처 컨테이너에 아키텍처를 지정할 수 있다. 예를 들어, 64비트 호스트에서 32비트 바이너리를 실행하는 컨테이너라면 32비트 아키텍처로 지정할 수 있다. 패키지를 다운로드 받는 등의 작업을 수행하는 아키텍처에 의존적인 컨테이너 스크립트가 잘 동작할 수 있도록 해준다. 컨테이너의 아키텍처를 지정한다. 가능한 옵션은 아래와 같다. , , , <!-- Hostname -->호스트 이름 utsname 섹션은 컨테이너 내에서 설정할 호스트 이름을 정의한다. 컨테이너는 시스템의 호스트 이름을 변경하지 않고도 자신의 호스트 이름을 변경할 수 있다. 즉, 컨테이너마다 호스트 이름을 설정할 수 있다. 컨테이너의 호스트 이름을 지정한다. <!-- Halt signal -->종료 시그널 lxc-stop이 컨테이너를 깨끗이 종료를 시키기 위해서 보낼 시그널의 이름이나 숫자를 지정할 수 있다. init 시스템마다 깨끗한 종료를 위해 각기 다른 시그널을 사용할 수 있다. 이 옵션은 kill(1)에서 사용하는 것 처럼 시그널을 지정할 수 있다. 예를 들어 SIGPWR, SIGRTMIN+14, SIGRTMAX-10 또는 숫자를 지정할 수 있다. 기본 시그널은 SIGPWR이다. 컨테이너를 종료할 때 사용할 시그널을 지정한다. <!-- Reboot signal -->재부팅 시그널 lxc-stop이 컨테이너를 재부팅하기 위해 보낼 시그널의 이름이나 숫자를 지정할 수 있다. 이 옵션은 kill(1)에서 사용하는 것 처럼 시그널을 지정할 수 있다. 예를 들어 SIGINT, SIGRTMIN+14, SIGRTMAX-10 또는 숫자를 지정할 수 있다. 기본 시그널은 SIGINT이다. 컨테이너를 재부팅할 때 사용할 시그널을 지정한다. <!-- Stop signal -->강제종료 시그널 lxc-stop이 컨테이너를 강제종료하기 위해 보낼 시그널의 이름이나 숫자를 지정할 수 있다. 이 옵션은 kill(1)에서 사용하는 것 처럼 시그널을 지정할 수 있다. 예를 들>어 SIGKILL, SIGRTMIN+14, SIGRTMAX-10 또는 숫자를 지정할 수 있다. 기본 시그널은 SIGKILL이다. 컨테이너를 강제종료할 때 사용할 시그널을 지정한다. <!-- Init command -->Init 명령어 컨테이너의 init으로 사용할 명령어를 설정한다. 이 옵션은 lxc-execute을 사용할 때는 무시된다. 기본값은 /sbin/init이다. init으로 사용할 바이저리의 컨테이너 루트 파일시스템에서의 절대 경로. <!-- Init ID -->Init이 사용할 ID lxc-execute가 실행하는 컨테이너의 init 및 명령어가 사용할 UID/GID를 지정한다. 이 옵션들은 lxc-execute가 사용자 네임스페이스 안에서 실행될 때만 적용된다. 기본 값: UID(0), GID(0) init이 사용자 네임스페이스 안에서 사용할 UID. init이 사용자 네임스페이스 안에서 사용할 GID. <!-- Ephemeral -->임시 컨테이너 컨테이너가 종료될 때, 해당 컨테이너를 제거할지 여부를 지정할 수 있다. 지정 가능한 값은 0 또는 1이다. 1로 설정하면, 컨테이너를 종료할 때 해당 컨테이너를 제거한다. <!-- Network -->네트워크 네트워크 섹션은 어떻게 네트워크를 컨테이너 내에서 가상화할지를 정의한다. 네트워크 가상화는 2개의 계층으로 동작한다. 네트워크 가상화를 위해서, 컨테이너의 네트워크 인터페이스가 인수로 지정되어야 한다. 시스템이 하나의 물리적인 네트워크 인터페이스를 갖고 있어도, 컨테이너 내에서 여러개의 가상화 인터페이스들을 사용할 수 있다. 값을 지정하지 않고 사용하여 이전에 설정했던 모든 네트워크 옵션들을 초기화할 수 있다. 컨테이너가 어떤 종류의 네트워크 가상화를 사용할지 지정한다. 필드부터 새로운 네트워크 설정이 시작된다. 이 방법으로 여러개의 네트워크 가상화 형태를 같은 컨테이너에 지정할 수 있다. 그리고 여러개의 네트워크 인터페이스를 하나의 컨테이너에 지정할 수도 있다. 지정 가능한 형태는 아래와 같다. 호스트의 네트워크 네임스페이스를 공유한다. 이렇게 하면 호스트의 네트워크 장치를 컨테이너 내에서 사용가능하다. 컨테이너와 호스트 둘다 init에서 upstart를 사용하는 경우, (예를 들어) 컨테이너에서 'halt'를 하면, 호스트의 것도 종료된다. 는 루프백 인터페이스만 생성한다. 한 쪽은 컨테이너로, 다른 한쪽은 옵션으로 지정한 브리지로 붙은 가상 이더넷(veth) 장치 쌍을 생성한다. 만약 브리지가 지정되지 않았다면, 어떤 브리지에도 붙지 않은 veth 장치 쌍을 만든다. 브리지는 컨테이너 시작전에 시스템에서 생성해야 한다. lxc는 컨테이너 이외의 설정에 대해서는 다루지 않는다. 기본값으로 lxc는 컨테이너 바깥에 속할 네트워크 디바이스의 이름을 정해준다. 이름을 변경하기 원한다면, lxc가 지정한 이름으로 설정하도록 옵션을 사용하여야 한다. (비특권 컨테이너는 불가능하다. 이 옵션은 보안상의 이유로 무시될 것이다) vlan 인터페이스는 로 지정한 인터페이스에 연결되고, 컨테이너로 할당된다. vlan의 식별자는 옵션으로 지정한다. macvlan 인터페이스는 로 지정한 인터페이스에 연결되고, 컨테이너로 할당된다. 은 같은 상위 디바이스에 있는 다른 macvlan과 통신할 때 사용하는 모드를 지정한다. 지정할 수 있는 모드는 、、、이다. 모드는 디바이스가 같은 상위디바이스의 어떤 장치와도 통신하지 않는다. (기본값) 새로운 가상 이더넷 포트 통합모드(Virtual Ethernet Port Aggregator), 즉 모드는 인접한 브리지가 소스와 목적지가 로컬인 모든 프레임들을 macvlan 포트로 반환한다고 가정한다. 즉, 브리지가 reflective relay로 설정되어 있다는 것이다. 상위장치에서 들어오는 브로드캐스트 프레임들은 모든 macvlan 인터페이스에게 보내져버린다. 로컬 프레임들은 로컬로 보내지지 않는다. 모드는 같은 포트의 다른 macvlan 인터페이스 사이에 간단한 브리지를 제공한다. 어떤 인터페이스에서 다른 인터페이스로 프레임은 직접 전달된다. 하지만 외부로는 보내지지 않는다. 브로드캐스트 프레임들은 모든 다른 브리지 포트들과 외부 인터페이스에 전달된다. 그러나 reflective relay로 다시 돌아왔을 때는, 그것들을 다시 전송하지 않는다. 모든 MAC 주소를 알기 때문에, macvlan 브리지모드는 브리지 모듈처럼 학습이나 STP를 요구하지 않는다. 모드는 물리 인터페이스로 부터 받은 모든 프레임들을 macvlan 인터페이스로 포워딩한다. 모드만이 하나의 물리 인터페이스를 설정하는게 가능하다. 로 지정한 이미 존재하는 인터페이스를 컨테이너로 할당된다. 네트워크에 수행할 작업을 지정한다. 인터페이스를 활성화시킨다. 실제 네트워크 트래픽에 사용할 인터페이스를 지정한다. 해당 인터페이스의 최대 전송 단위(MTU)를 지정한다. 인터페이스 이름은 동적으로 할당된다. 그러나, 컨테이너가 일반적으로 사용하는 이름과 다른 이름이 필요하다면, (예: eth0) 이 옵션은 컨테이너 내에 있는 인터페이스의 이름을 지정한 것으로 변경할 수 있다. 가상 인터페이스의 MAC 주소는 기본적으로 동적 할당된다. 그러나 몇몇가지 이유로 MAC 주소 충돌 문제를 해결하거나, 언제나 같은 링크 로컬 IPv6 주소가 필요하다면, 이 옵션이 필요하다. 주소의 "x"는 무작위한 값으로 바뀐다. 템플릿에서 하드웨어 주소를 설정하는데 유용하다. 가상 인터페이스에서 사용할 IPv4 주소를 지정한다. 여러 행으로 여러개의 IPv4 주소를 지정할 수 있다. 주소의 형식은 x.y.z.t/m으로, 예를 들어 192.168.1.123/24이다. 브로드 캐스트 주소는 같은 행의 주소 바로 오른쪽에 지정하면 된다. 컨테이너 내부에서 게이트웨이로 사용할 IPv4 주소를 지정한다. 주소 형식은 x.y.z.t로, 예를 들면 192.168.1.123이다. 라는 특별한 값을 지정할 수있다. 이것은 ( 에서 지정된) 브리지 인터페이스의 첫번째 주소를 가져와 게이트 주소로 사용한다. 는 네트워크 형태가 나 일 때만 지정 가능하다. 가상 인터페이스에서 사용할 IPv6 주소를 지정한다. 여러 행으로 여러개의 IPv6 주소를 지정할 수 있다. 주소의 형식은 x::y/m으로, 예를 들어 2003:db8:1:0:214:1234:fe0b:3596/64이다. 컨테이너 내부에서 게이트웨이로 사용할 IPv4 주소를 지정한다. 주소 형식은 x::y로, 예를 들면 2003:db8:1:0::1이다. 라는 특별한 값을 지정할 수있다. 이것은 ( 에서 지정된) 브리지 인터페이스의 첫번째 주소를 가져와 게이트 주소로 사용한다. 는 네트워크 형태가 나 일 때만 지정 가능하다. 네트워크를 설정하고 생성한 후에 호스트 쪽에서 실행되는 스크립트를 지정한다. 다음 인수들이 스크립트에 넘겨진다 : 컨테이너 이름, 설정 섹션 이름(net). 그 후 인수는 훅 스크립트을 사용하는 설정 섹션에 달려있다. 다음 인수들은 네트워크 시스템에 의해 사용되어진다 : 실행 컨텍스트(up), 네트워크 형태(empty/veth/macvlan/phys). 네트워크 형태에 따라서 다음 인수들이 넘겨진다 : veth/macvlan/phys의 경우, (호스트 쪽의) 장치 이름. 스크립트의 표준출력은 debug 수준 로그로 납겨진다. 표준 에러는 로그로 남겨지지는 않지만, 표준 에러를 표준 출력으로 리다이렉션하여 로그로 남길 수 있다. 네트워크를 제거한 후에 호스트 쪽에서 실행되는 스크립트를 지정한다. 다음 인수들이 스크립트에 넘겨진다 : 컨테이너 이름, 설정 섹션 이름(net). 그 후 인수는 훅 스크립트을 사용하는 설정 섹션에 달려있다. 다음 인수들은 네트워크 시스템에 의해 사용되어진다 : 실행 컨텍스트(down), 네트워크 형태(empty/veth/macvlan/phys). 네트워크 형태에 따라서 다음 인수들이 넘겨진다 : veth/macvlan/phys의 경우, (호스트 쪽의) 장치 이름. 스크립트의 표준출력은 debug 수준 로그로 납겨진다. 표준 에러는 로그로 남겨지지는 않지만, 표준 에러를 표준 출력으로 리다이렉션하여 로그로 남길 수 있다. <!-- New pseudo tty instance (devpts) -->새로운 pseudo tty 인스턴스(devpts) 강한 고립을 위해 컨테이너는 자기자신만의 pseudo tty를 가질 수 있다. 만약 지정되었다면, 컨테이너는 새 pseudo tty 인스턴스를 갖는다. 그리고 이것을 자기자신 전용으로 만든다. 지정하는 값은 pseudo tty의 최대 개수를 지정한다. (이 제한은 아직 구현되지 않았다) <!-- Container system console -->컨테이너 시스템 콘솔 컨테이너에 루트 파일시스템이 설정되어 있고 inittab 파일에 콘솔을 사용하는 것이 설정되어 있다면, 콘솔의 출력을 어디로 할지 지정할 수 있다. 콘솔의 출력을 쓸 파일의 경로를 지정한다. 콘솔을 붙일 장치의 경로를 지정한다. 'none'이라는 값은 단순히 콘솔을 비활성화 시킨다. 만약 응용 프로그램이 쓸 수 있는 콘솔 장치 파일이 루트 파일시스템에 있으면, 메시지가 호스트 쪽에 출력되므로 이 설정은 위험할 수 있다. <!-- Console through the ttys -->tty를 통한 콘솔 컨테이너에 루트 파일시스템이 설정되어 있고 inittab 파일에 tty에서 getty를 실행하는 것이 설정되어 있다면, 이 옵션은 유용하다. 이 옵션은 컨테이너에서 사용가능한 tty의 개수를 지정한다. 컨테이너의 inittab 파일에 설정된 getty의 개수는 이 옵션에서 정한 tty의 개수보다 크면 안된다. 그렇지 않으면 초과된 getty 세션은 무한히 죽고 다시 살아나기를 반복하며 콘솔이나 /var/log/messages에 계속 메시지를 띄울 것이다. 컨테이너가 만들 수 있는 tty의 개수를 지정한다. <!-- Console devices location -->콘솔 장치 위치 LXC 콘솔은 호스트에서 생성된 Unix98 PTY와 컨테이너 내에 바인드 마운트될 장치들을 통해 제공된다. 기본적으로 /dev/console와 /dev/ttyN를 바인드 마운트 한다. 이것은 게스트에서 패키지 업그레이드를 방해하는 요인이 된다. 그래서 /dev 밑에 LXC가 파일을 생성하고 바인드 마운트할 디렉토리의 위치를 따로 지정해 줄 수 있다. 그리고 만들어진 파일들은 /dev/console와 /dev/ttyN에 심볼릭 링크된다. 심볼릭 링크들은 삭제하거나 대체하는 것이 가능하므로 패키지 업그레이드는 성공적으로 이루어질 수 있다. 컨테이너 콘솔 장치를 생성할 /dev 밑의 디렉토리를 지정한다. <!-- /dev directory -->/dev 디렉토리 기본적으로 lxc는 약간의 심볼릭 링크(fd, stdin, stdout, stderr)를 컨테이너의 /dev 디렉토리에 생성한다. 그러나 자동으로 장치 노드 항목들을 생성해주지 않는다. 컨테이너의 루트 파일시스템에서 필요로하는 /dev를 생성할 수 있게 하는 것이다. lxc.autodev가 1로 지정되었다면, 컨테이너 루트 파일시스템을 마운트 한 후, LXC가 /dev 밑에 새로운 tmpfs(최대 500k)를 마운트 해준다. 그리고 최소한의 장치만을 채워준다. 이것은 "systemd" 기반의 "init" 환경의 컨테이너를 시작할 때 일반적으로 필요하지만, 다른 환경의 경우는 선택적인 요소이다. 컨테이너의 부가적인 장치들은 훅 스크립트를 사용하여 /dev 디렉토리에 생성할 수 있다. 컨테이너 시작시 /dev을 마운트하고 최소한으로 /dev를 구성할지 지정한다. 0이면 해당 동작을 수행하지 않는다. <!-- Enable kmsg symlink -->kmsg 심볼릭링크 사용 /dev/console에 대한 심볼릭 링크로 /dev/kmsg를 생성한다. 이것을 1로 지정하면 /dev/kmsg 심볼릭링크를 사용한다. <!-- Mount points -->마운트 포인트 마운트 포인트 섹션은 마운트가 될 각각의 장소를 지정한다. 이 마운트 포인트들은 컨테이너에서만 보이고 외부에서 실행하는 프로세스들에겐 보이지 않는다. 이는 예를 들어 /etc, /var, /home을 마운트할 때 유용하다. 주의 - 보통 LXC는 마운트 대상과 상대 경로로 된 바인드 마운트 소스들이 컨테이너의 루트 아래에 있도록 보장할 것이다. 이는 호스트 디렉토리와 파일들을 겹쳐서 마운트하는 유형의 공격을 피하기 위한 것이다. (절대 경로로 된 마운트 소스 내에 존재하는 심볼릭 링크들은 무시될 것이다.) 하지만, 만약 컨테이너 설정에서 컨테이너 사용자가 제어할 수 있는, 예를 들어 /home/joe와 같은 디렉토리를 컨테이너 내의 path에 먼저 마운트 하고 나서, path 내에 또 마운트를 하는 경우가 있다면, 컨테이너 사용자가 자신의 home 디렉토리에 있는 심볼릭링크를 정확한 시간에 조작하여, TOCTTOU (역주 : Time of check to time of use) 공격이 가능할 것이다. 마운트 정보를 담은 fstab 형식으로 된 파일의 위치를 지정한다. 이 마운트 대상 위치들은 대부분 상대경로로 되어 있으며, 이는 마운트된 컨테이너 루트에서의 상대경로를 의미한다. proc proc proc nodev,noexec,nosuid 0 0 위의 예는 proc 파일시스템을 컨테이너 루트 파일시스템의 위치와 상관없이 컨테이너의 /proc에 마운트시키는 예제이다. 이는 백엔드 파일시스템 블록 장치뿐만 아니라 컨테이너의 복제에도 유연하게 대처할 수 있다. 이미지 파일이나 블록 장치에서 마운트된 파일시스템의 경우, 3번째 필드 (fs_vfstype)는 mount 8 와 같이 auto를 지정할수 없으며, 명시적으로 지정해야 한다. fstab의 형식으로, 한 줄당 마운트 포인트 하나를 지정한다. 또한 마운트 옵션에 아래 2가지 옵션을 추가적으로 사용할 수 있다. 이는 LXC 자체적으로 사용하는 옵션이다. 은 마운트를 못하더라도, 실패로 처리하지 않게 한다. 와 는 마운트할 때, 디렉토리(dir) 또는 파일(file)을 생성한다. 일반적인 커널의 파일시스템을 자동으로 마운트할지 지정한다. 이 옵션을 사용하면 설정을 매우 편하게 할 수 있다. 사용할 수 있는 파일시스템들은 아래와 같다. (or ): /proc 을 읽기/쓰기 가능으로 마운트, 그러나 /proc/sys과 /proc/sysrq-trigger는 읽기 전용으로 다시 마운트 (보안상의 이유 및 컨테이너 고립을 위해) : /proc 전체를 읽기/쓰기 가능으로 마운트 (or ): /sys/devices/virtual/net는 쓰기 가능으로, /sys는 읽기 전용으로 마운트. : /sys를 읽기 전용으로 마운트 (보안상의 이유 및 컨테이너 고립을 위해) : /sys를 읽기/쓰기 가능으로 마운트 : /sys/fs/cgroup를 tmpfs로 마운트. 컨테이너가 추가될 모든 계층의 디렉토리 생성. cgroup 이름의 하위 디렉토리 생성. 컨테이너 자신의 cgroup을 해당 디렉토리에 마운트. 컨테이너는 자신의 cgroup 디렉토리에는 쓰기가 가능하지만 부모의 디렉토리는 읽기전용으로 마운트 하므로 쓰기가 불가능하다. : 와 유사, 단, 전부 읽기 전용으로 마운트 : 와 유사, 단, 전부 읽기/쓰기 가능으로 마운트. 컨테이너 자신의 cgroup에 이르기까지의 경로가 모두 쓰기 가능이 되지만, cgroup 파일시스템이 아닌 /sys/fs/cgroup의 tmpfs의 일부로써 존재하게 되는 것에 주의해야 한다. (별다른 옵션 없이): 컨테이너가 CAP_SYS_ADMIN capability를 유지하고 있는 경우 을 기본으로 사용한다. 그렇지 않다면 를 사용한다. : /sys/fs/cgroup을 tmpfs로 마운트. 컨테이너가 추가될 모든 계층의 디렉토리 생성. 호스트의 디렉토리들을 컨테이너로 바인드 마운트하고 컨테이너 자신의 cgroup을 제외한 모든 디렉토리는 읽기 전용으로 변경. 비교하자면, 의 경우에는 컨테이너 자신의 cgroup에 이르기까지 모든 경로는 단순하게 tmpfs 아래에 있는 디렉토리에 불과하다. 하지만, 여기서는 비록 컨테이너 자신의 cgroup 이외에는 모두 읽기 전용이긴 하나 /sys/fs/cgroup/$hierarchy이 호스트의 모든 cgroup 계층구조를 포함하고 있다. 이는 컨테이너에게 너무 많은 정보를 노출시킬 수 있다. : 와 유사, 단, 전부 읽기 전용으로 마운트 : 와 유사, 단, 전부 읽기/쓰기 가능으로 마운트. 이 경우는 컨테이너가 자기자신의 cgroup을 벗어날 수 있다. (만약 컨테이너가 CAP_SYS_ADMIN을 갖고 있다면, cgroup 파일시스템 자체를 마운트할 수 있음을 주의해야 한다. 이렇게 하면 같은 결과를 가져올 수 있다) (별다른 옵션 없이): 컨테이너가 CAP_SYS_ADMIN capability를 유지하고 있는 경우 을 기본으로 사용한다. 그렇지 않다면 를 사용한다. cgroup 네임스페이스가 사용 가능한 경우, 마운트 옵션들은 전부 무시될 것이다. 컨테이너가 직접 파일시스템을 마운트하기 때문이며, 컨테이너 초기화시 해당 옵션이 혼란을 줄 수 있기 때문이다. cgroup 파일시스템이 자동으로 마운트되는게 활성화되어 있다면, /sys/fs/cgroup 밑의 tmpfs는 언제나 읽기/쓰기 가능으로 마운트 된다.(단, 과 의 경우에는 각각 계층 /sys/fs/cgroup/$hierarchy이 읽기전용이 될 수는 있다) 아래의 Ubuntu 명령어에 대응하기 위함이다. mountall 8 해당 명령어는 컨테이너 부팅시에 /sys/fs/cgroup가 읽기전용으로 마운트되어 있고, 컨테이너가 CAP_SYS_ADMIN을 갖고 있지 않아 이를 읽기/쓰기 전용으로 다시 마운트 못할 경우, 부팅시에 사용자의 입력을 기다리게 만들기 때문이다. 예제: lxc.mount.auto = proc sys cgroup lxc.mount.auto = proc:rw sys:rw cgroup-full:rw <!-- Root file system -->루트 파일시스템 컨테이너의 루트 파일시스템은 호스트 시스템과 다르게 구성할 수 있다. 컨테이너의 루트 파일시스템을 지정한다. 이미지 파일 또는 블록 장치의 디렉토리가 될 수도 있다. 만약 지정되지 않으면 컨테이너는 자신의 루트 파일시스템을 호스트와 공유한다. 디렉토리 또는 간단한 블록 장치로 구성된 컨테이너를 위해서 경로이름이 사용될 수 있다. 만약 루트 파일시스템이 nbd 장치의 경우, nbd:file:1는 file을 nbd 장치로 사용하고 1번 파티션이 루트 파일시스템으로 마운트되도록 지정한다. nbd:file는 nbd 장치 자체가 마운트되어야 한다고 지정한다. overlayfs:/lower:/upper는 루트 파일시스템이 읽기전용으로 마운트된 /lower를 /upper가 읽기/쓰기 가능으로 오버레이 마운트되도록 지정한다. aufs:/lower:/upper는 aufs에서 위와같이 지정한다. overlayfs와 aufs는 여러개의 /lower 디렉토리를 지정할 수 있다. loop:/file는 lxc가 /file을 loop 장치로 사용하고 loop 장치를 마운트하도록 지정한다. 루트 파일시스템을 변경하기 전에, 을 어디에 재귀적으로 바인드할지 정한다. 이는 pivot_root 8 시스템 콜의 성공을 보장한다. 어떤 디렉토리도 좋으며, 기본값으로도 보통 동작할 것이다. 루트 파일시스템을 마운트 할때 사용할 부가적인 마운트 옵션. 사용하고자 하는 백엔드 루트파일 시스템의 종류를 지정한다. 'dir' 또는 'zfs'로 지정할 수 있다. 컨테이너 시작시 어떤 종류인지 추정하는 동안, 시간이 소요될 수 있다. 이 값을 지정함으로써 추가적인 처리를 피할 수 있다. <!-- Control group -->컨트롤 그룹 컨트롤 그룹 섹션은 (lxc와는) 다른 서브시스템의 설정을 포함한다. lxc는 서브시스템의 이름을 정확히 체크하지 않는다. 이는 컨테이너를 시작할 때까지는 설정 상의 에러를 잡아내기 힘들게 한다. 그러나 다른 차후에 들어올 수 있는 서브시스템을 지원할 수 있는 장점도 있다. 지정한 컨트롤 그룹의 값을 지정한다. 서브시스템의 이름은 컨트롤 그룹에서의 이름이다. 사용가능한 이름이나 값의 문법에 대해서는 LXC에서 따로 신경쓰지 않으며, 컨테이너가 시작하는 시점에 리눅스 커널이 해당 기능을 지원하는지에 달려있다. 예를 들면 이다. Capabilities 컨테이너가 root로 실행된다면, 컨테이너 내에서 capability를 제거할 수 있다. 컨테이너에서 제거할 capability를 지정한다. 한 줄에 여러개의 capability를 공백(space)으로 구분하여 정의할 수 있다. 형식은 capability 정의에서 "CAP_" 접두사를 빼고 소문자로 작성하는 것이다. 예를들어 CAP_SYS_MODULE의 경우는 sys_module이다. 아래를 참조할 수 있다. capabilities 7 값을 공백으로 지정하면, 해당 설정 이전에 지정했던 capability를 모두 취소한다. (lxc.cap.drop에 아무 것도 지정하지 않은 상태가 된다.) 컨테이너에서 유지할 capability를 지정한다. 다른 capability는 모두 제거될 것이다. "none"이라는 값을 지정하면, lxc는 해당 시점에서 갖고 있던 모든 capability를 제거한다. 모든 capability를 제거하기 위해서는 "none" 하나만 사용하면 된다. <!-- Apparmor profile -->Apparmor 프로파일 lxc가 apparmor를 지원하도록 컴파일된 후 설치되었고, 호스트 시스템에서 apparmor가 활성화되었다면, 컨테이너에서 따라야할 apparmor 프로파일을 컨테이너 설정에서 지정할 수 있다. 기본값은 호스트 커널이 cgroup 네임스페이스를 지원하면 lxc-container-default-cgns이고, 그렇지 않다면 lxc-container-default이다. 컨테이너가 따라야할 apparmor 프로파일을 지정한다. 컨테이너가 apparmor로 인한 제한을 받지 않도록 하려면, 아래와 같이 지정하면 된다. lxc.aa_profile = unconfined apparmor 프로파일이 변경되지 않아야 한다면(중첩 컨테이너 안에 있고, 이미 confined된 경우), 아래와 같이 지정하면 된다. lxc.aa_profile = unchanged apparmor 프로파일은 경로이름 기반이므로, 공격자로부터 효과적으로 파일 제한을 하기위해서는 마운트 제한이 요구된다. 하지만 이 마운트 제한들은 upstream 커널에서는 구현되어 있지 않다. 마운트 제한 없이도, apparmor 프로파일은 우연한 손상에 대해서 보호가 가능하다. 만약 이 플래그가 0(기본값)이라면, 커널에 apparmor의 마운트 기능이 부족했을때 컨테이너가 시작되지 않는다. 커널을 업그레이드한 후에 해당 기능이 빠졌는지 여부를 검사하기 위함이다. 부분적인 apparmor 보호 하에서도 컨테이너를 시작하려면, 플래그를 1로 지정하면 된다. <!-- SELinux context -->SELinux 컨텍스트 lxc가 SELinux를 지원하도록 컴파일된 후 설치되었고, 호스트 시스템에서 SELinux 컨텍스트가 활성화되었다면, 컨테이너에서 따라야할 SELinux 컨텍스트를 컨테이너 설정에서 지정할 수 있다. 기본값은 unconfined_t이다. 이는 lxc는 컨텍스트를 변경하지않음을 의미한다. 정책 예제와 추가적인 정보를 원한다면 @DATADIR@/lxc/selinux/lxc.te를 참고하면 된다. 컨테이너가 따라야할 SELinux 컨텍스트를 지정하거나, unconfined_t를 지정할 수 있다. 예를 들어 아래와 같이 지정 가능하다. lxc.se_context = system_u:system_r:lxc_t:s0:c22 <!-- Seccomp configuration -->Seccomp 설정 컨테이너는 seccomp 프로파일을 로드하여 사용가능한 시스템콜의 수를 줄인 체로 실행할 수 있다. seccomp 설정파일은 첫번째 행이 버전번호, 두번째 행이 정책 타입, 시작하며 그 이후에 설정 사항들이 포함되어야 한다. 현재는 버전1과 2만 지원된다. 버전 1에서는 정책은 단순한 화이트리스트이다. 그러므로 두번째 라인은 반드시 "whitelist"여야 한다. 파일의 나머지 내용은 한 줄에 하나의 시스템콜 번호로 채워진다. 화이트리스트에 없는 번호는 컨테이너에서 블랙리스트로 들어간다. 버전 2에서는 폴리시는 블랙리스트 또는 화이트리스트가 될 수 있다. 그리고 각 규칙와 각 정책의 기본 동작, 아키텍쳐별 시스템콜 설정, 텍스트로된 이름을 지원한다. 아래는 블랙리스트 정책 예제이다. 아래 정책에서는 mknod를 제외한 모든 시스템콜이 허용된다. mknod시에는 아무것도 수행하지 않고 0(성공)을 반환한다. 2 blacklist mknod errno 0 컨테이너가 시작되기전에 읽어올 seccomp 설정이 담긴 파일을 지정한다. <!-- UID mappings -->UID 매핑 컨테이너는 사용자와 그룹 ID 매핑을 통해 자신만의 사용자 네임스페이스 내에서 실행될수 있다. 예를 들어서 컨테이너의 UID 0번을 호스트의 UID 200000으로 매핑할 수 있다. 컨테이너의 루트 사용자는 컨테이너에서는 특권을 가지고 있지만, 호스트에서는 특권을 가지고 있지 않게 된다. 보통 시스템 컨테이너는 ID들의 범위를 지정하려 할텐데 그 역시도 지정 가능하다. 예를 들어서, 컨테이너의 UID와 GID를 0 ~ 20,000를 호스트의 200,000 ~ 220,000로 설정 가능하다. 4개의 값이 제공되어야 한다. 첫 번째는 'u', 'g', 'b' 문자로 각각 UID, GID, 또는 UID 및 GID 를 가리킨다. 그 다음은 사용자 네임스페이스내에서의 UID, 그다음은 호스트의 UID, 그리고 마지막으로 매핑할 ID의 범위를 지정한다. <!-- Container hooks -->컨테이너 훅 컨테이너 훅은 컨테이너의 생명주기 내에서 다양한 상황에 실행되는 프로그램 또는 스크립트이다. 컨테이너 훅이 실행될 때, 정보는 명령어 인수나 환경 변수를 통해 넘겨진다. 인수 : 컨테이너 이름 섹션 (보통 'lxc') 훅 종류 ('clone', 'pre-mount' 등) 추가 인수. clone 훅일 경우, lxc-clone에게 넘였던 추가 인수들이 넘어온다. stop 훅일 경우, 컨테이너의 네임스페이스 각각에 대한 이름과 파일 디스크립터의 경로가 넘어온다. 환경 변수 : LXC_NAME: 컨테이너 이름 LXC_ROOTFS_MOUNT: 마운트될 루트 파일시스템의 경로 LXC_CONFIG_FILE: 컨테이너 설정파일의 경로 LXC_SRC_NAME: clone 훅의 경우, 원본 컨테이너의 이름 LXC_ROOTFS_PATH: 컨테이너의 lxc.rootfs 항목. 이 것은 마운트된 루트 파일시스템을 가리키는 것이 아님에 주의해야한다. 그 목적을 위해서는 LXC_ROOTFS_MOUNT를 사용해야 한다. 훅의 표준출력은 debug 수준 로그로 납겨진다. 표준 에러는 로그로 남겨지지는 않지만, 표준 에러를 표준 출력으로 리 다이렉션하여 로그로 남길 수 있다. 컨테이너의 tty, 콘솔의 생성 및 마운트가 되기 전에, 호스트의 네임스페이스에서 실행되는 훅. 컨테이너의 마운트 네임스페이스 안에서 루트 파일시스템이 세팅되기 전에 실행되는 훅. 예를 들어 암호화 파일시스템을 마운트 하는 등의 루트 파일시스템을 조작할 수 있게 해준다. 이 훅에서 마운트를 하더라도 호스트에는 반영되지 않는다. (mounts propagation은 제외) 그래서 컨테이너가 종료되면 자동적으로 정리된다. 마운트가 완료된 후 pivot_root 전에, 컨테이너의 마운트 네임스페이스에서 실행되는 훅. == 1가 지정되어 있는 경우에 마운트 완료시 마운트 훅도 실행 된 후 pivot_root전에, 컨테이너의 마운트 네임스페이스에서 실행되는 훅. 이 훅의 목적은 systemd 기반의 컨테이너에서 autodev 옵션을 사용하는 경우 /dev 디렉토리를 구성할 때 도움을 주기위한 것이다. 훅이 실행될 때, 컨테이너의 /dev 경로는 ${} 환경변수에 대한 경로이다. 컨테이너의 init이 실행되기 직전에 컨테이너의 네임스페이스에서 실행되는 훅. 컨테이너 내에서 해당 프로그램이 실행될 수 있는 상태여야 한다. 컨테이너가 종료된 후 컨테이너 네임스페이스에 대한 참조를 넘겨받는 호스트의 네임스페이스에서 실행되는 훅. 각각의 네임스페이스들은 훅에 추가인수로 넘겨진다. 해당 인수는 네임스페이스의 이름과 네임스페이스의 파일 디스크립터를 얻어올 수 있는 파일이름을 가지고 있으며, 콜론으로 구분된다. 네임스페이스 이름은 /proc/PID/ns 디렉토리 내의 파일 이름이다. 예를 들어 마운트 네임스페이스에 대응하는 인수는 일반적으로 mnt:/proc/PID/fd/12와 같이 된다. 컨테이너가 종료된 후 호스트의 네임스페이스에서 실행되는 훅. 컨테이너가 새로운 컨테이너로 복제되었을 경우 실행되는 훅. 아래를 참조하면 더 자세한 정보를 얻을 수 있다. lxc-clone 1 컨테이너가 제거될 때 실행되는 훅. <!-- Container hooks Environment Variables -->컨테이너 훅 환경 변수 훅이 시작될때 설정 정보를 제공하고 훅의 기능을 돕기 위해 몇가지 환경 변수가 사용 가능하다. 모든 컨텍스트에서 모든 변수가 사용 가능하진 않다. 특히, 모든 경로는 호스트 시스템에서의 경로이며, 훅에서는 유효하지 않다. LXC 컨테이너의 이름. 일반적인 로그 환경에서 로그메시지에 유용하게 사용할 수 있다. [] 컨테이너 설정파일의 호스트에서의 경로. 이것은 다른 방법으로는 얻을 수 없는 추가적인 정보룰 찾을 수 있도록, 컨테이너가 참조하는 원래의 최상위 설정파일의 경로를 제공한다. [] NULL이 아니라면, 컨테이너의 콘솔의 출력이 저장될 경로. [] [] NULL이 아니라면, 컨테이너의 콘솔의 로그 출력이 저장될 경로. [] 처음에 컨테이너가 마운트 되는 장소. 이것은 시작되는 컨테이너 인스턴스를 위한 루트 파일시스템의 호스트에서의 경로이다. 해당 인스턴스에 대한 변경이 이루어져야 하는 장소이다. [] rootfs.mount에 마운트된 컨테이너 루트의 호스트에서의 경로이다. [] clone 훅에서만 사용된다. 원본 컨테이너의 이름을 지정한다. stop 훅에서만 사용된다. 값이 "stop"이면 컨테이너가 종료되는 것을, "reboot"이면 컨테이너가 재부팅되는 것을 의미한다. 이 변수가 지정되지 않았다면, 현재 버전의 lxc는 cgroup 네임스페이스를 지원하지 않는다. 만약 지정되었고 값이 1이라면, lxc는 cgroup 네임스페이스를 지원하는 것이다. 단, kernel에서의 cgroup 네임스페이스 지원을 보장하는 것이 아님에 주의해야 한다. lxcfs 마운트 훅에서 사용된다. <!-- Logging -->로그 로그는 각 컨테이너마다 설정할 수 있다. 기본적으로 lxc 패키지가 어떻게 컴파일되었는지에 달려있지만, 컨테이너 시작시에는 error 수준 로그만 기록된다. 컨테이너 경로나 @LOGPATH@ 밑에 컨테이너의 이름을 따서(뒤에 '.log'를 붙여서) 로그 파일을 생성한다. 기본 로그 수준과 로그파일은 컨테이너 설정파일로 지정 가능하며, 기본 동작을 덮어버린다. 마찬가지로 설 정파일 항목들은 lxc-start 명령어의 옵션으로 덮어쓸 수 있다. 기록할 로그 수준. 로그 수준은 0 ~ 8 사이의 정수이다. 숫자가 작을수록 더 자세히 로그를 기록한다. 구체적으로는 0 = trace, 1 = debug, 2 = info, 3 = notice, 4 = warn, 5 = error, 6 = critical, 7 = alert, 8 = fatal이다. 지정하지 않은 경우, 기본값은 5 (error)로, 에러 이거나 그보다 심각한 상황의 로그를 기록한다. (훅 스크립트 및 네트워크 인터페이스 up/down 스크립트 같은) 스크립트가 호출이되면, 스크립트의 표준 입출력은 1 번, debug 수준으로 기록된다. 로그 정보를 쓸 파일. <!-- Autostart -->자동시작 자동시작 옵션들은 자동시작할 컨테이너 지정 및 순서 설정이 가능하다. 이 옵션들은 LXC 도구로 직접 사용하거나 배포판들이 제공하는 외부 도구에 의해 사용될 수도 있다. 컨테이너가 자동으로 시작될지 여부. 유효한 값은 0 (off) 또는 1 (on)이다. 컨테이너가 시작된 후 다음 컨테이너가 시작되기 전까지 기다릴 시간(초). 다수의 컨테이너를 한번에 자동시작할 때, 컨테이너의 부팅 순서를 결정할 때 사용하는 정수를 지정한다. 값이 0이 아니라면, 컨테이너가 초기화되기 전 (pre-start 훅이 실행 되기 전) 호스트로부터 마운트 네임스페이스를 unshare 한다. 시작시에 CAP_SYS_ADMIN 캐퍼빌리티가 요구된다. 기본값은 0이다. 컨테이너를 추가할 컨테이너 그룹을 지정한다. 여러값을 설정할 수 있으며, 여러번 지정 가능하다. 설정된 그룹은 연관된 컨테이너들을 시작할 때 사용된다. <!-- Autostart and System Boot -->자동시작과 시스템 부팅 각각의 컨테이너는 여러 그룹에 속할수도 있고 아무그룹에도 속하지 않을 수 있다. 두개의 그룹은 특수한데, 하나는 NULL 그룹이고 컨테이너가 아무그룹에도 속하지 않을때 사용된다. 그리고 나머지 하나는 "onboot" 그룹이다. LXC 서비스가 활성화된 상태로 시스템이 부팅될 때, 먼저 lxc.start.auto == 1이고 "onboot" 그룹인 컨테이너들을 시작하려고 시도한다. 시작과정은 lxc.start.order의 순서대로 이루어진다. 만약 lxc.start.delay가 지정 되었다면, 다음 컨테이너를 시작하려고 시도>하기 전, 현재 컨테이너의 초기화 및 호스트 시스템의 부하를 줄이기 위해서 지연시간을 준다.

저장되는 시스템 객체를 생성한다. name은 다른 lxc 명령어들에서 특정 컨테이너를 지정하는데 사용된다. 객체는 @LXCPATH@에 작성되는 디렉토리이며, 자신의 name으로 구분되어 진다. 객체는 응용 프로그램이 사용할 수 있고 볼 수 있는 여러 자원들의 정의이다. 설정파일이 많은 정보를 담고 있을수록 컨테이너는 더욱더 고립될 수 있고, 응용 프로그램은 더욱더 격리될 수 있다. 만약 설정파일 config_file가 지정되지 않았다면, 컨테이너는 프로세스, sysv ipc, 마운트 포인트에 대한 기본적인 고립 상태로 만들어진다. <!-- Options -->옵션 컨테이너 가상화 및 고립 기능을 설정하는 설정파일을 지정한다. lxc-create 명령어는 'lxc-template' 스크립트를 호출한다. template은 'lxc-template' 스크립트의 짧은 이름으로, busybox, debian, fedora, ubuntu, sshd 등이 있다. 스크립트의 구조에 대해 궁금할 때는 @LXCTEMPLATEDIR@에 있는 예제들을 참고하면 된다. template 대신 스크립트의 전체 경로를 지정할 수도 있다. "none"으로 지정하면 루트파일시스템 생성을 강제로 건너뛸 수 있다. 'backingstore'는 'dir', 'lvm', 'loop', 'btrfs', 'zfs', 'rbd', 'best'를 지정할 수 있다. 기본 값은 'dir'로 컨테이너 루트 파일시스템을 의미하며 @LXCPATH@/container/rootfs이하 디렉토리를 가리킨다. 'dir'은 옵션으로 컨테이너 루트 파일시스템이 어느 경로에 위치할지 지정할 수 있으며, --dir ROOTFS로 가능하다. ('none'은 'dir'과 동일하다) 'btrfs'가 지정되어 있다면, 타겍 파일시스템은 반드시 btrfs여야 한다. 그리고 컨테이너 루트 파일시스템은 새로운 서브볼륨으로 생성된다. 이는 스냅샷된 복제물을 만들지만, rsync --one-filesystem는 분리된 파일시스템으로 취급하게 된다. 'lvm'으로 지정되있다면, lvm 블록 디바이스가 사용되며, 이때 사용가능한 옵션은 다음과 같다 : --lvname lvname1는 이름이 lvname1인 LV를 만든다(기본값은 컨테이너 이름). --vgname vgname1는 이름이 vgname1인 볼륨그룹 안에 LV를 만든다(기본값은 lxc). --thinpool thinpool1는 thinpool1라는 풀 안에 있는 thin-provisioned 볼륨으로 LV를 만든다(기본값은 lxc). --fstype FSTYPE는 LV의 파일시스템을 FSTYPE으로 지정한다(기본값은 ext4). --fssize SIZE는 LV의 크기를 지정한다(기본값은 1G). 'loop'로 지정되어 있다면, 'lvm'과 비슷하게 --fstype FSTYPE과 --fssize SIZE를 사용할 수 있다(기본값은 'lvm'과 동일). 'rbd'로 지정되어 있다면, ceph.conf내 적절하게 설정사항이 있어야 하고 ceph.client.admin.keyring가 정의되어 있어야 한다. 아래 옵션을 지정할 수 있다 : --rbdname RBDNAME는 생성하는 블록 장치의 이름을 RBDNAME로 지정한다(기본값은 컨테이너의 이름). --rbdpool POOL는 블록 장치를 넣을 풀을 POOL로 지정한다(기본값은 'lxc').

[root@lxc sshd]$ tree -d rootfs rootfs |-- bin |-- dev | |-- pts | `-- shm | `-- network |-- etc | `-- ssh |-- lib |-- proc |-- root |-- sbin |-- sys |-- usr `-- var |-- empty | `-- sshd |-- lib | `-- empty | `-- sshd `-- run `-- sshd 그리고, 해당 마운트 포인트 파일의 내용은 아래와 같다. [root@lxc sshd]$ cat fstab /lib /home/root/sshd/rootfs/lib none ro,bind 0 0 /bin /home/root/sshd/rootfs/bin none ro,bind 0 0 /usr /home/root/sshd/rootfs/usr none ro,bind 0 0 /sbin /home/root/sshd/rootfs/sbin none ro,bind 0 0 어떻게 컨테이너 내에서 시스템을 실행하는가? 컨테이너 내에서 시스템을 실행하는 것은 역설적으로 어플리케이션을 실행하는 것보다 쉽다. 왜 그럴까? 왜냐하면, 어떤 자원이 고립되어야 하는지 고려할 필요가 없다. 모든 자원이 고립되면 된다. 자원들은 별다른 설정없이 고립된다고 지정만 해도 된다. 왜냐하면 컨테이너가 그 자원들을 세팅할 것이기 때문이다. 예를 들어 ipv4 주소는 시스템 컨테이너의 init 스크립트들을 통해 세팅된다. 아래는 마운트 포인트 파일의 예제이다. [root@lxc debian]$ cat fstab /dev /home/root/debian/rootfs/dev none bind 0 0 /dev/pts /home/root/debian/rootfs/dev/pts none bind 0 0 설정을 돕기 위해서 컨테이너에 부가 정보를 추가할 수 있다. 아래와 같이 호스트에 있는 resolv.conf를 컨테이너 안에서 접근할 수 있다. /etc/resolv.conf /home/root/debian/rootfs/etc/resolv.conf none bind 0 0 <!-- Container life cycle -->컨테이너의 생명주기 컨테이너가 생성될때, 컨테이너는 설정정보를 포함하게 된다. 프로세스가 실행될때, 컨테이너는 시작되고 실행된다. 컨테이너 내에서 실행되던 마지막 프로세스가 종료되면, 컨테이너는 종료된다. 컨테이너의 초기화가 실패했을 경우, (아래 그림처럼)중단 상태로 바뀌게 된다. <!-- Configuration -->설정 컨테이너는 설정파일에 의해서 설정된다. 설정파일의 형식은 다음을 참조하면 된다. lxc.conf 5 <!--Creating / Destroying container (persistent container) -->컨테이너의 생성/제거 (지속 컨테이너) 지속성 컨테이너 객체는 lxc-create 명령어로 생성된다. 컨테이너이름을 인수로 받으며, 부가적인 설정파일과 템플릿을 지정한다. 여기서 지정하는 이름은 다른 명령어들을 사용할 때 해당 컨테이너를 참조하기 위해 사용된다. lxc-destroy 명령어는 컨테이너 객체를 제거한다. lxc-create -n foo lxc-destroy -n foo <!-- Volatile container -->휘발성 컨테이너 컨테이너 시작전에 컨테이너 오브젝트를 생성하는 것이 의무는 아니다. 컨테이너는 설정파일을 파라미터로 넣어서 바로 시작할 수도 있다. <!-- Starting / Stopping container -->컨테이너의 시작과 종료 컨테이너가 생성하면 응용 프로그램/시스템이 실행될 준비를 마친 것이다. 실행하는 것이 바로 lxc-execute와 lxc-start 명령어의 목적이다. 응용프로그램 시작전에 컨테이너가 생성되어 있지 않다면, 컨테이너는 명령어의 인수로 넘겼던 설정파일을 사용한다. 그런 인수마저 없다면, 기본 고립 환경을 사용한다. 만약 응용프로그램이 종료되면, 컨테이너도 역시 종료된다. 실행중인 응용프로그램을 종료시키고 싶다면 lxc-stop를 사용하면 된다. 컨테이너 내부에서 응용프로그램을 실행하는 것은 시스템을 실행하는 것과는 차이가 있다. 이런 이유로 아래의 두가지 명령어가 사용된다. lxc-execute -n foo [-f config] /bin/bash lxc-start -n foo [-f config] [/bin/bash] lxc-execute 명령어는 컨테이너 내부에서 lxc-init 프로세스를 통해 실행할 명령어를 지정할 수 있다. lxc-init는 지정한 명령어를 실행한 후, 그 명령어로 실행된 모든 프로세스들이 종료되기를 기다린다. (컨테이너 내부에서 데몬을 지원하기 위해서이다) 다시 말해서, 컨테이너 내부에서 lxc-init는 1번 pid를 갖고, 응용프로그램의 첫번째 프로세스는 2번 pid를 가진다. lxc-start 명령어는 지정한 명령어를 컨테이너 내에서 직접 실행한다. 첫 프로세스의 pid는 1번이다. 만약 어떤 명령어도 지정되지 않으면, lxc.init_cmd에 지정된 명령어를 실행한다. 이마저도 지정되있지 않으면, /sbin/init를 실행한다. 요약하자면, lxc-execute는 응용 프로그램 실행을 위해서, lxc-start는 시스템 실행을 위해 적합하다. 만약 어플리케이션이 더이상 응답하지 않거나, 접근이 불가능하거나, 스스로 종료되지 못할 경우, lxc-stop 명령어는 컨테이너 내의 모든 프로세스들을 가차없이 종료시킬 것이다. lxc-stop -n foo <!-- Connect to an available tty -->사용가능한 tty 접속 컨테이너에 tty가 설정되어 있다면, tty를 통해 컨테이너에 접근할 수 있다. 아래 명령어를 통해 사용될 가능한 tty를 제공하는 것은 컨테이너에 달려있다. tty가 종료되었을 때는 다시 로그인하지 않고도 재접속할 수 있다. lxc-console -n foo -t 3 <!-- Freeze / Unfreeze container -->컨테이너 동결/동결 해제 스케줄링 등을 위해 컨테이너에 속해있는 모든 프로세스를 정지 시키는 것은 때로 유용할 수 있다. 아래 명령어들을 사용하면 된다. lxc-freeze -n foo 는 모든 프로세스들을 인터럽트 불가능한 상태로 만든다. lxc-unfreeze -n foo 는 모든 프로세스를 정지 해제 시킨다. 이 기능은 커널에서 cgroup freezer 기능이 활성화 되어 있어야 사용 가능하다. <!-- Getting information about container --> 컨테이너 관련 정보 얻어오기 컨테이너가 많이 존재하는 경우, 어떤 것이 생성되고 제거됬는지, 어떤 것이 실행 중인지 또는 어떤 프로세스들이 특정 컨테이너 내에서 실행되는지를 따라가기 힘들다. 이를 위해 다음과 같은 명령어들이 유용하게 사용될 수 있다. lxc-ls lxc-info -n foo lxc-ls는 시스템의 컨테이너들의 리스트를 표시한다. lxc-info는 지정한 컨테이너의 정보를 얻어온다. 아래는 명령어들을 조합하여 컨테이너들의 리스트를 얻어오고 상태를 출력하는 예제이다. for i in $(lxc-ls -1); do lxc-info -n $i done <!-- Monitoring container -->컨테이너 모니터링 컨테이너의 상태를 추적하는 것은 때때로 매우 유용하다. 예를 들어, 상태를 모니터링하거나, 스크립트에서 특정상태를 기다리는 경우이다. lxc-monitor 명령어는 하나 또는 여러개의 컨테이너들을 모니터링한다. 이 명령어의 인수로 정규표현식을 넘길 수도 있다. 예를 들면, lxc-monitor -n "foo|bar" 는 'foo'와 'bar'라는 이름의 컨테이너의 상태 변화를 모니터링한다. 그리고, lxc-monitor -n ".*" 는 모든 컨테이너를 모니터링한다. 'foo' 컨테이너가 시작되고 몇 가지 작업을 수행하고 종료된 경우, 출력은 다음과 같다. 'foo' changed state to [STARTING] 'foo' changed state to [RUNNING] 'foo' changed state to [STOPPING] 'foo' changed state to [STOPPED] lxc-wait 명령어는 지정한 상태로 변화되는 것을 기다린다. 이 명령어는 컨테이너의 시작이나 종료와 동기화되는 스크립트를 작성할 때 유용하다. 인수는 다른 상태들을 OR로 묶어서 지정해 줄 수 있다. 아래 예제는 백그라운드에서 어떻게 컨테이너의 상태 변화를 기다리는지 보여준다. <!-- Setting the control group for container --> 컨테이너 컨트롤 그룹 설정 컨테이너는 컨트롤 그룹과 결합되어 있다. 컨테이너가 시작되면 컨트롤그룹이 만들어지고 해당 컨트롤 그룹과 연결된다. 컨테이너가 실행중일 때, lxc-cgroup 명령어를 이용해 컨트롤 그룹 속성은 읽거나 수정될 수 있다. lxc-cgroup 명령어는 컨테이너와 연결된 컨트롤 그룹 서브시스템의 값을 얻어오거나 설정한다. 서브시스템의 이름은 사용자가 결정하며, 이 명령어는 이름이 적합한지 여부를 검사하지 않는다. 만약 서브시스템의 이름이 없다면 명령어는 실패할 것이다. lxc-cgroup -n foo cpuset.cpus 는 해당 서브시스템의 내용을 표시한다. lxc-cgroup -n foo cpu.shares 512 는 해당 서브시스템의 값을 설정한다. <!-- Bugs -->버그 lxc는 아직 개발중이다. 그래서 명령어 사용법이나, API가 변경될 수 있다. 버전 1.0.0은 변경되지 않는 고정된 버전이다. &seealso; <!-- Author -->저자 Daniel Lezcano daniel.lezcano@free.fr lxc-2.0.7/doc/rootfs/0000755061062106075000000000000013041440546011401

This command is mainly provided for testing purposes. Despite its name, it always uses clone rather than unshare to create the new task with fresh namespaces. Apart from testing kernel regressions this should make no difference. Options Specify the namespaces to attach to, as a pipe-separated list, e.g. NETWORK|IPC. Allowed values are MOUNT, PID, UTSNAME, IPC, USER and NETWORK. This allows one to change the context of the process to e.g. the network namespace of the container while retaining the other namespaces as those of the host. (The pipe symbol needs to be escaped, e.g. MOUNT\|PID or quoted, e.g. "MOUNT|PID".) Specify a userid which the new task should become. Set the hostname in the new container. Only allowed if the UTSNAME namespace is set. Move the named interface into the container. Only allowed if the NETWORK namespace is set. You may specify this argument multiple times to move multiple interfaces into container. Daemonize (do not wait for the container to exit before exiting) Mount default filesystems (/proc /dev/shm and /dev/mqueue) in the container. Only allowed if MOUNT namespace is set. Examples To spawn a new shell with its own UTS (hostname) namespace, lxc-unshare -s UTSNAME /bin/bash If the hostname is changed in that shell, the change will not be reflected on the host. To spawn a shell in a new network, pid, and mount namespace, lxc-unshare -s "NETWORK|PID|MOUNT" /bin/bash The resulting shell will have pid 1 and will see no network interfaces. After re-mounting /proc in that shell, mount -t proc proc /proc ps output will show there are no other processes in the namespace. To spawn a shell in a new network, pid, mount, and hostname namespace. lxc-unshare -s "NETWORK|PID|MOUNT|UTSNAME" -M -H slave -i veth1 /bin/bash The resulting shell will have pid 1 and will see two network interfaces (lo and veth1). The hostname will be "slave" and /proc will have been remounted. ps output will show there are no other processes in the namespace. &seealso; Author Daniel Lezcano daniel.lezcano@free.fr

lxc 7 Version @PACKAGE_VERSION@ lxc Linux コンテナ <!-- Quick start -->クイックスタート 急いでいて、この man ページすら読みたくないという場合は、いいでしょう、 保証はないですが、あらかじめ準備されている設定テンプレートを使ったコンテナ内でシェルを動かすためのコマンドを紹介しましょう。 @BINDIR@/lxc-execute -n foo -f @DOCDIR@/examples/lxc-macvlan.conf /bin/bash <!-- Overview -->概要 コンテナ技術は、メインストリームの linux kernel で活発に開発が進んでいる技術です。 コンテナ技術は、process container という名前でも知られる control groups の機能を使って、リソース管理を提供し、名前空間を使って、リソースの隔離を提供します。 linux コンテナ (lxc) は、ユーザースペースのコンテナオブジェクトを提供するための新しい機能を使う事を目指しています。 この新しい機能とは、アプリケーションやシステムでの利用を目的とした、完全なリソースの隔離やリソースコントロールを提供する機能です。 このプロジェクトの第一の目的は、コンテナプロジェクトに参加するカーネル開発者の作業を快適にすることと、特に新機能である Checkpoint/Restart 機能への取り組みを続ける事です。 lxc コマンドは、シンプルなコマンドでコンテナの管理を簡単に行えるように小さく、他の目的のために使うのに充分な機能を持っています。 <!-- Requirements -->必要条件 lxc は、カーネルが提供するいくつかの機能に依存しており、その機能がアクティブになっている必要があります。 機能が足りない場合は、lxc は、いくつかの機能が制限されるか、単純に動作が失敗します。 以下のリストは、コンテナの全機能を有効にするために、カーネルで有効にする必要のある機能の一覧です。 * General setup * Control Group support -> Namespace cgroup subsystem -> Freezer cgroup subsystem -> Cpuset support -> Simple CPU accounting cgroup subsystem -> Resource counters -> Memory resource controllers for Control Groups * Group CPU scheduler -> Basis for grouping tasks (Control Groups) * Namespaces support -> UTS namespace -> IPC namespace -> User namespace -> Pid namespace -> Network namespace * Device Drivers * Character devices -> Support multiple instances of devpts * Network device support -> MAC-VLAN support -> Virtual ethernet pair device * Networking * Networking options -> 802.1d Ethernet Bridging * Security options -> File POSIX Capabilities 2.6.32 以上のバージョンが採用されているディストリビューションならば、lxc は動作するでしょう。 機能的には若干少ない形ですが、充分に楽しめるはずです。 ヘルパースクリプトの lxc-checkconfig を使って、あなたのカーネルの設定に関する情報を取得できるでしょう。 control group は、どこにでもマウント可能です。 例えば、mount -t cgroup cgroup /cgroup のようにです。 しかし、cgroup の階層構造を /sys/fs/cgroup 以下にマウントするために cgmanager や cgroup-lite や systemd の使用が推奨されています。 <!-- Functional specification -->機能仕様 コンテナは、コンテナ内で実行されているシステムやアプリケーションに対するホストのリソースのいくつかが、隔離されているオブジェクトです。 アプリケーション／システムは、あらかじめ作成された設定もしくは開始コマンドのパラメータで指定された設定で、コンテナ内で実行されます。 どうやってコンテナ内でアプリケーションを実行するのでしょう? アプリケーションを実行する前に、隔離したいリソースについて知っておくべきです。 デフォルトの設定では、pid、sysv ipc、マウントポイントが隔離されます。 コンテナ内でシンプルなシェルを実行したい場合で、特に rootfs を共有したい場合、基本的な設定が必要です。 もし、sshd のようなアプリケーションを実行したい場合、新しいネットワークスタックと、新しいホスト名を準備しなくてはなりません。 もし、同じファイル (/var/run/httpd.pid 等) の衝突を避けたい場合、空の /var/run/ を再度マウントしなければなりません。 どんな場合でも、衝突を避けたい場合、コンテナ専用の rootfs を指定することができます。 rootfs はディレクトリツリーとなる事も可能で、前もって元の rootfs を bind マウントし、しかし、自身の /etc や /homeを使って。自身のディストリビューションを使うことが可能です。 ここで、sshd のためのディレクトリツリーのサンプルを示しましょう。 [root@lxc sshd]$ tree -d rootfs rootfs |-- bin |-- dev | |-- pts | `-- shm | `-- network |-- etc | `-- ssh |-- lib |-- proc |-- root |-- sbin |-- sys |-- usr `-- var |-- empty | `-- sshd |-- lib | `-- empty | `-- sshd `-- run `-- sshd そして、それに対応するマウントポイントのファイルは以下のようになります。 [root@lxc sshd]$ cat fstab /lib /home/root/sshd/rootfs/lib none ro,bind 0 0 /bin /home/root/sshd/rootfs/bin none ro,bind 0 0 /usr /home/root/sshd/rootfs/usr none ro,bind 0 0 /sbin /home/root/sshd/rootfs/sbin none ro,bind 0 0 コンテナ内でシステムを実行する方法は? コンテナ内でシステムを実行するのは、逆説的ではありますが、アプリケーションを実行するよりも簡単です。 それは、隔離するリソースについて考える必要がないからで、全てを隔離する必要があるからです。 他のリソースは、コンテナが設定を行うので、設定なしで隔離されるように指定されます。 例えば、IPv4 アドレスはコンテナの init スクリプトでシステムによってセットアップされるでしょう。 以下に、(システムを実行するときの) マウントポイントファイルを示します。 [root@lxc debian]$ cat fstab /dev /home/root/debian/rootfs/dev none bind 0 0 /dev/pts /home/root/debian/rootfs/dev/pts none bind 0 0 設定を手助けするために、コンテナに更なる情報を追加することも可能です。 例えば、ホスト上に存在する resolv.conf ファイルをコンテナからアクセス可能にするには、以下のようにします。 /etc/resolv.conf /home/root/debian/rootfs/etc/resolv.conf none bind 0 0 <!-- Container life cycle -->コンテナのライフサイクル コンテナが作成されるとき、コンテナは設定情報を含みます。 プロセスが生成されるとき、コンテナは開始し、実行されるでしょう。 コンテナ内で実行されている最後のプロセスが終了したとき、コンテナは停止します。 コンテナの初期化時の失敗の場合は、(以下の図の) 中断の状態を通ります。 <!-- Configuration -->設定 コンテナは設定ファイル経由で設定します。設定の書式は以下で説明しています。 lxc.conf 5 <!--Creating / Destroying container (persistent container) -->コンテナの生成と終了 (持続性のコンテナ) 持続性のコンテナオブジェクトは lxc-create コマンドで作成することができます。 コマンドにはコンテナ名をパラメータとして、オプションで設定ファイルとテンプレートを指定します。 ここで指定する名前は、他のコマンドからこのコンテナを参照する際に使います。 lxc-destroy コマンドはコンテナオブジェクトを破壊します。 lxc-create -n foo lxc-destroy -n foo <!-- Volatile container -->揮発性のコンテナ コンテナを開始する前にコンテナオブジェクトを作成する必要はありません。 コンテナを設定ファイルのパラメータで指定して直接開始することができます。 <!-- Starting / Stopping container -->コンテナの開始と終了 コンテナが作成されると、アプリケーションもしくはシステムとして実行することができます。 このために使用するのが lxc-execute と lxc-start コマンドです。 アプリケーションが開始する前にコンテナが作成されなかった場合、コンテナはコマンドへ与えるパラメータを取得するのに設定ファイルを使うでしょう。 もし、このようなパラメータもない場合は、デフォルトで指定されている通りに隔離されます。 アプリケーションが終了した場合、コンテナも停止しますが、実行中のアプリケーションを停止するには lxc-stop を使用する必要があります。 コンテナ内のアプリケーションの実行は、正確にはシステムとして実行するのとは異なります。 そのような理由で、コンテナ内でアプリケーションを実行するためのコマンドには、2 種類の違ったものがあります。 lxc-execute -n foo [-f config] /bin/bash lxc-start -n foo [-f config] [/bin/bash] lxc-execute コマンドは、lxc-init プロセス経由で、コンテナ内で特定のコマンドを実行します。 lxc-init はコマンドを実行した後、(コンテナ内でのデーモンの実行をサポートするために) 実行したコマンドと生成された全てのプロセスが終了するのを待ちます。 言いかえると、コンテナ内では lxc-init は pid 1 を持ち、アプリケーションの最初のプロセスは pid 2 をもちます。 lxc-start コマンドは、コンテナ内の特定のコマンドを直接実行します。 最初のプロセスの pid が 1 となります。 もし、実行するコマンドが指定されない場合は、lxc-start は lxc.init_cmd で設定されたコマンドを実行します。もし lxc.init_cmd が設定されていない場合は /sbin/init を実行します。 まとめると、lxc-execute はアプリケーションを実行するためのコマンドであり、lxc-start はシステムを実行するのにより適したコマンドです。 もしアプリケーションの反応がなくなった場合や、アクセスできなくなった場合、自分で終了することができない場合は、荒っぽいですが、lxc-stop コマンドがコンテナ内の全てのプロセスを容赦なく停止させてくれるでしょう。 <!-- Connect to an available tty -->利用可能な tty への接続 コンテナが tty を持つように設定されているならば、tty を通してコンテナにアクセスすることができます。 それは以下のコマンドが使う tty がコンテナで利用可能に設定されているか次第です。 tty が失われたとき、再度のログインなしでその tty に再接続することが可能です。 lxc-console -n foo -t 3 <!-- Freeze / Unfreeze container -->コンテナの凍結と解凍 ジョブスケジューリングなどで、コンテナに属する全てのプロセスを停止する事が役に立つときがあります。 コマンド lxc-freeze -n foo は、全てのプロセスを中断不可能な状態に置きます。そして、 lxc-unfreeze -n foo その全てのプロセスを再開します。 この機能は、カーネルで cgroup freezer 機能が有効になっている場合に使用可能です。 <!-- Getting information about container --> コンテナに関する情報の取得 多数のコンテナが存在する場合、それらが実行されたり破壊されたりすること、何が実行されていて、特定のコンテナ内で実行されている pid が何であるかをフォローするのは大変です。 このような時には、以下のようなコマンドが役に立つかもしれません。 lxc-ls lxc-info -n foo lxc-ls は、システムのコンテナを一覧します。 lxc-info は、指定したコンテナに関する情報を取得します。 ここで、以上のコマンドを組み合わせて、どのようにしたら全てのコンテナのリストと、それぞれの状態が得られるかの例を示します。 for i in $(lxc-ls -1); do lxc-info -n $i done <!-- Monitoring container -->コンテナのモニタリング 時々、コンテナの状態を追跡することが出来ると便利な事があります。 例えば、状態をモニタリングしたり、スクリプト内で特定の状態を待ったりするような場合です。 lxc-monitor コマンドは、一つもしくはいくつかのコンテナをモニタリングします。 このコマンドのパラメータは、正規表現を受け付けます。例えば lxc-monitor -n "foo|bar" は 'foo' と 'bar' という名前のコンテナの状態をモニタリングします。そして、 lxc-monitor -n ".*" は全てのコンテナの状態をモニタリングします。 コンテナ 'foo' が開始され、いくつか処理を行い、終了した場合、出力は以下のようになります。 'foo' changed state to [STARTING] 'foo' changed state to [RUNNING] 'foo' changed state to [STOPPING] 'foo' changed state to [STOPPED] lxc-wait コマンドは指定した状態を待って、終了します。 これは、コンテナの開始や終了に同期したいスクリプトで役に立ちます。 パラメータは、異なった状態の論理和 (OR) を指定します。 以下の例は、バックグラウンドで実行されたコンテナをどのようにして待つかを示します。 <!-- Setting the control group for container --> コンテナの control group の設定 コンテナは control group と結合しています。 コンテナが開始すると control group が生成され、それと結びつけられます。 control group のプロパティは、lxc-cgroup コマンドを使って、コンテナが実行中に読み取ったり、変更したりすることができます。 lxc-cgroup コマンドは、コンテナと結びつけられている control group サブシステムを設定したり、取得したりするのに使います。 サブシステム名の指定はユーザが行ない、このコマンドはサブシステム名の文法チェックは一切行ないません。 もし、指定したサブシステム名が存在しない場合は、コマンドの実行は失敗します。 lxc-cgroup -n foo cpuset.cpus は、このサブシステムの内容を表示します。 lxc-cgroup -n foo cpu.shares 512 は、このサブシステムに指定した値を設定します。 <!-- Bugs -->バグ lxc はまだ開発中です。 従って、コマンドの文法や API

(コピーは一時的なコピーまたは永続的なコピーのどちらも可能です)。 このコマンドは lxc-clone と lxc-start-ephemeral の置き換えのコマンドです。 lxc-copy は、既存のコンテナのコピーを作成します。 コピーは元のコンテナの完全なクローンにできます。この場合、単にコンテナのルートファイルシステムのすべてが、新しいコンテナにコピーされます。 また、スナップショットを取得することも可能です。すなわち、元のコンテナの小さなコピーオンライトのコピーにするということです。この場合、コピーで指定するバッキングストレージがスナップショットをサポートしている必要があります。 スナップショットをサポートしているバッキングストレージは、現時点では aufs、btrfs、lvm (lvm デバイスはスナップショットのスナップショットはサポートしていません)、overlay、zfs です。 コピー先のバッキングストレージは、元のコンテナと同じタイプになるでしょう。ただし、ディレクトリバックエンドのコンテナのスナップショットは aufs と overlayfs で取得できますので例外です。 -e オプションを指定した場合は、元のコンテナの一時的なスナップショットを作成し、起動します。一時的なコンテナの場合、設定ファイルに lxc.ephemeral = 1 がセットされ、シャットダウン後に削除されます。 -e と -D を同時に指定すると、元のコンテナの一時的ではないスナップショットを作成し、起動します。 -e を指定した場合で、-N でコンテナの名前を指定しない場合は、スナップショットの名前はランダムで命名されます。 -e で作成し、起動したコンテナは、コンテナ独自のマウントを行えます。現時点では aufs、bind、overlay という 3 つのタイプのマウントがサポートされています。 マウントタイプは -m オプションのサブオプションとして指定します。この指定はカンマ区切りで複数回指定できます。 aufs と overlay マウントの場合は、現時点では -m overlay=/src:/dest のように指定します。マウント先の dest を指定しない場合は、dest は src と同じになります。 読み込み専用の bind マウントは -m bind=/src:/dest:ro のように指定します。読み書き可能な bind マウントは -m bind=/src:/dest:rw のように指定します。bind マウントのデフォルトは読み書き可能ですので、読み書き可能なマウントを行う場合は省略できます。マウント先の dest を指定しない場合は、dest は src と同じになります。 複数のマウントを行う場合の例を示すと、-m bind=/src1:/dest1:ro,bind=/src2:ro,overlay=/src3:/dest3 のようになります。 -m オプションで指定するマウント、オプション、指定フォーマットは変更される可能性があります。 <!-- Options -->オプション コピー先のコンテナの名前。 コピー先のパス。 元のコンテナをリネームします。 元のコンテナのスナップショットを作成します。コピー先のバッキングストレージがスナップショットをサポートしている必要があります。現時点では aufs、btrfs、lvm、overlay、zfs が対象となります。 スナップショットしたコンテナをフォアグラウンドで起動します。スナップショットしたコンテナのコンソールは現在の tty にアタッチされます。(このオプションは -e と同時の場合のみ指定できます。) スナップショットしたコンテナをデーモンで起動します (一時的なコンテナではこのモードがデフォルトです)。 コンテナは tty を持ちませんので、エラーが発生しても何も表示されません。エラーをチェックするにはログファイルを使います。(このオプションは -e と同時の場合のみ指定できます。) スナップショットするコンテナで行うマウントを指定します。マウントタイプは {aufs, bind, overlay} のどれかで指定します。例えば のようになります。(このオプションは -e と同時の場合のみ指定できます。) コピー先コンテナのバッキングストレージのタイプを指定します。ここで 'backingsotrage' は 'aufs'、'btrfs'、'dir'、'lvm'、'loop'、'overlay'、'zfs' のどれかです。 'lvm' ファイルシステムのサイズを指定します。 -e オプションと同時にこのオプションを使うと、一時的でないコンテナを作成し、起動します。 このオプションを指定すると、元のコンテナのホスト名をコピー先でもそのまま使います。 このオプションを指定すると、元のコンテナの MAC アドレスをコピー先でもそのまま使います。 <!-- Copy hook -->コピー時のフック コピーされるコンテナに 1 つ以上の lxc.hook.clone の指定が存在する場合、指定されたフックは新しいコンテナに対して呼ばれます。

60 秒待ち、return します。 コンテナが 60 秒の間にクリーンに終了するのに失敗した場合、lxc.stopsignal (デフォルトは SIGKILL です) を送り、強制的にシャットダウンします。 リブートのリクエストは lxc.rebootsignal に設定されたシグナルをコンテナの init プロセスに送ります (デフォルトは SIGINT です)。 -W, -r, -s, -k, --nokill オプションは実行する際のアクションを指定します。 -W は、指定したアクションの後に、lxc-stop は速やかに終了します。 一方、-t TIMEOUT はコンテナが完全にシャットダウンやリブートするのを待つ時間の最大値を設定します。 <!-- Options -->オプション コンテナのリブートをリクエストします。

<!-- Examples -->例 存在するコンテナ内で新しいシェルを生成するには、以下のようにします。 lxc-attach -n container 実行中の Debian コンテナの cron サービスを再起動するには、以下のように実行します。 lxc-attach -n container -- /etc/init.d/cron restart NET_ADMIN ケーパビリティを持たない実行中のコンテナのネットワークインターフェース eth1 の動作を停止させるには、ケーパビリティを増加させるために オプションを指定し、ip ツールがインストールされていることを前提に、以下のように実行します。 lxc-attach -n container -e -- /sbin/ip link delete eth1 <!-- Compatibility -->互換性 (pid とマウント名前空間を含む) コンテナに対する完全なアタッチを行うには 3.8 以上、もしくはパッチを適用したカーネルが必要となります。 詳しくは lxc のウェブサイトを参照してください。 パッチが当たっていない 3.8 より小さなバージョンのカーネルを使った場合は、lxc-attach の実行は失敗するでしょう。 しかし、もし を使用して、アタッチするものを NETWORK, IPC, UTSNAME の 1 つか複数の名前空間に限定して使用すれば、バージョン 3.0 以上のパッチを適用していないカーネルでもアタッチが成功するでしょう。 ユーザ名前空間へのアタッチは、ユーザ名前空間機能を有効にした 3.8 以上のカーネルでサポートされます。 <!-- Notes -->注意 Linux の /proc と /sys ファイルシステムは名前空間によって影響を受けるある程度の情報を持っています。 これは /proc 内のプロセス ID の名前のディレクトリや、/sys/class/net 内のネットワークインターフェース名のディレクトリなどです。 擬似ファイルシステムをマウントしているプロセスの名前空間が、どのような情報を表示するかを決定します。 /proc や /sys にアクセスしているプロセスの名前空間が決定するのではありません。 を使ってコンテナの pid 名前空間のみをアタッチし、マウント名前空間 (これはコンテナの /proc を含み、ホストのは含まないでしょう) はアタッチしない場合、 のコンテンツはコンテナのものではなく、ホストのものとなります。 似たような事例として、ネットワーク名前空間のみをアタッチして、/sys/class/net のコンテンツを読んだ場合も同じような事が起こるでしょう。 この問題への対処のために、 オプションが /proc と /sys が提供されています。 これにより、アタッチするプロセスのネットワーク/pid 名前空間のコンテキストを反映させることができます。ホストの実際のファイルシステムに影響を与えないために、実行前にはマウント名前空間は unshare されます (lxc-unshare のように)。 これは、/proc と /sys ファイルシステム以外はホストのマウント名前空間と同じである、新しいマウント名前空間がプロセスに与えられるということです。 以前のバージョンの lxc-attach は、いくつかの重要なサブシステムに対して、書き込み可能な cgroup 内に配置することなしに、ユーザがコンテナの名前空間にアタッチできたバグがありました。 新しいバージョンの lxc-attach は、このような重要なサブシステムに対して、ユーザが書き込み可能な cgroup 内にいるかどうかをチェックします。 したがって、ユーザによっては lxc-attach は不意に失敗するかもしれません (例えば、非特権ユーザが、ログイン時に重要であるサブシステムの書き込み可能な cgroup に配置されていないようなシステムで)。しかし、この振る舞いは正しく、よりセキュアです。 <!-- Security -->セキュリティ と オプションの使用には注意を払うべきです。 不適切に使用した場合、コンテナの隔離を破壊してしまう可能性があります。 &seealso;

オプションは実行する動作を指定します。何も指定しない場合は、コンテナを起動します。 -a, -g は、どのコンテナを対象にするかを指定するのに使います。デフォルトでは、lxc.group が指定されていないコンテナにだけが対象となります。 -t TIMEOUT はコンテナが完全にシャットダウンもしくはリブートを待つ最大時間を指定します。 <!-- Options -->オプション コンテナのリブートを要求します。 クリーンなシャットダウンを要求します。もし、-t timeout が 0 より大きい場合で、コンテナがこの時間内にシャットダウンしない場合は、コンテナは -k kill オプションを指定した時のように kill されます。 コンテナのクリーンなシャットダウンを要求するのではなく、明確にコンテナの全てのタスクを kill します。 実際の動作は行わず、コンテナ名と次のコンテナを開始するまでの間隔の表示だけを行います。 コンテナの強制停止まで TIMEOUT 秒待ちます。 対象にするコンテナのグループのカンマ区切りのリスト (デフォルトでは lxc.group 指定のないコンテナ、つまり NULL グループが対象になります)。 このオプションは複数回指定することができ、オプションは連結されます。NULL もしくは空のグループは、NULL グループを処理すべき場所に指定された先頭のカンマ、末尾のカンマ、途中に現れる 2 つ続きのカンマ、空のオプション引数で指定することができます。 グループはコマンドラインで指定された順番に処理されます。-g オプションの複数回の呼び出しはカンマ区切りのリストと自由に混ぜることができ、指定した順番に連結されます。 lxc.group

システムサービスがホストシステムのブートおよびシャットダウン時に実行するように有効化されているとき、LXC システムサービスの一部として使用されます。 このコマンドはホストシステムのブート時に、どのコンテナをどういう順番で、それぞれのコンテナの起動間隔をどれくらい開けるかを選択するのに使います。 コンテナはいくつでもグループに属することができ、全く属さないことも可能です。特別なグループが 2 つ存在します。1 つは NULL グループです。これはどのグループにも属さないコンテナです。もう 1 つは "onboot" グループです。 LXC サービスが有効になった状態でシステムがブートすると、最初に "onboot" グループのメンバーである lxc.start.auto == 1 が設定されたコンテナを起動しようとします。起動は lxc.start.order の順に起動します。 lxc.start.delay が指定されている場合、現在対象となっているコンテナに初期化の時間を与え、ホストシステムの負荷を低減するために、次のコンテナを開始させるまでに遅延時間を与えます。 "onboot" グループのメンバーが開始した後、LXC システムは lxc.start.auto == 1 が設定された、どのグループのメンバーでもない (NULL グループの) コンテナのブートを

コンテナは、プロセスがコンテナを使う時に仮想化/隔離するシステムリソースのセットを定義することによって作成します。 デフォルトでは、pid, sysv ipc, マウントポイントが仮想化され、隔離されます。 他のシステムリソースは、設定ファイルで明確に定義されない限りは、コンテナをまたいで共有されます。 例えば、もしネットワークが設定されていなければ、コンテナを作成する側とコンテナでネットワークを共有します。 しかし、ネットワークが指定されれば、新しいネットワークスタックがコンテナ用に作成され、コンテナは作成元の環境のネットワークを使いません。 設定ファイルは、コンテナに割り当てられる様々なシステムリソースを定義します。 現時点では、utsname、ネットワーク、マウントポイント、root ファイルシステム、ユーザ名前空間、control groups がサポートされます。 設定ファイルのオプション一つを、key = value の形で一行で表します。 '#' は、その行はコメントであることを示します。 ケーパビリティや cgroup のオプションのような、リスト形式で指定するオプションでは、value がない形式で指定できます。このように使うと、それ以前に定義した値をすべてクリアします。 <!-- Configuration -->設定 複数の関係するコンテナの管理を容易にするために、コンテナの設定ファイルに別のファイルをロードすることが可能です。 例えば、ネットワークの設定を、複数のコンテナから include させるように 1 つのファイルに定義することが可能です。 その場合、コンテナが他のホストに移動すると、そのファイルだけを更新する必要があるかもしれません。 include させたいファイルを指定します。 include するファイルは、lxc 設定ファイルのフォーマットとして有効でなければいけません。 <!-- Architecture -->アーキテクチャ コンテナに対してアーキテクチャを設定することが可能です。 例えば、64 ビットのホスト上で 32 ビットのバイナリを動かすために 32 ビットアーキテクチャを設定することが可能です。 この設定を行うことにより、パッケージのダウンロードを行うなどの作業のうち、アーキテクチャ名に依存するような作業を行うコンテナスクリプトの修正を行います。 コンテナに設定するアーキテクチャを指定します。 有効なオプションは以下です。 , , , <!-- Hostname -->ホスト名 utsname セクションは、コンテナに設定されるホスト名を定義します。 コンテナは、システムのホスト名を変えることなく、自身のホスト名を持つ事が可能です。 このことにより、ホスト名はコンテナ専用となります。 コンテナのホスト名を指定します。 <!-- Halt signal -->クリーンなシャットダウン時のシグナル lxc-stop がコンテナをクリーンにシャットダウンするためにコンテナの init プロセスに送るシグナル名か番号を指定できます。 init システムによって、クリーンなシャットダウンを行うために使うシグナルは異なります。 このオプションではシグナルとして kill(1) で使う形式を指定することができます。 例えば SIGKILL, SIGRTMIN+14, SIGRTMAX-10 のような形式、もしくは数字を指定します。デフォルトのシグナルは SIGPWR です。 コンテナをシャットダウンするために使うシグナルを指定します。 リブート時のシグナル <!-- Reboot signal --> lxc-stop がコンテナをリブートするために送るシグナル名か番号を指定できます。 このオプションではシグナルとして kill(1) で使う形式を指定することができます。 例えば SIGKILL, SIGRTMIN+14, SIGRTMAX-10 のような形式、もしくは数字を指定します。デフォルトのシグナルは SIGINT です。 コンテナをリブートするために使うシグナルを指定します。 <!-- Stop signal -->強制停止時のシグナル lxc-stop がコンテナを強制的にシャットダウンするために送るシグナル名か番号を指定することができます。 このオプションではシグナルとして kill(1) で使う形式を指定することができます。 例えば SIGKILL, SIGRTMIN+14, SIGRTMAX-10 のような形式、もしくは数字を指定します。デフォルトのシグナルは SIGKILL です。 コンテナを停止するのに使用するシグナルを指定します。 <!-- Init command -->Init コマンド コンテナの init として使うコマンドを設定します。 このオプションは lxc-execute では無視されます。 デフォルトは /sbin/init です。 init として使うバイナリの、コンテナの rootfs からの絶対パスを指定します。 <!-- Init ID -->Init が使う ID lxc-execute が実行するコンテナの init と、その後に起動するコマンドが使用する UID/GID を設定します。 このオプションは lxc-execute がユーザ名前空間内で起動するときのみ使われます。 デフォルト値は UID(0), GID(0) です。 ユーザ名前空間内で init が使う UID です。 ユーザ名前空間内で init が使う GID です。 <!-- Ephemeral -->一時的なコンテナ シャットダウン後にコンテナを削除するかどうかを指定できます。 指定できる値は 0 または 1 のみです。この値を 1 に設定すると、シャットダウン後にコンテナを削除します。 <!-- Network -->ネットワーク ネットワークセクションは、コンテナ内でどのようにネットワークを仮想化するかを定義します。 ネットワークの仮想化はレイヤー 2 で作動します。 ネットワークの仮想化を使用するためには、コンテナのネットワークインターフェースを定義しなければなりません。 いくつかの仮想インターフェースをアサインすることができます。 そして、仮に物理ネットワークインターフェースが一つしかなくても、コンテナ内でいくつもの仮想インターフェースを使うことができます。 値を指定せずに使い、それ以前に定義されたすべてのネットワークオプションをクリアできます。 コンテナがどの種類のネットワーク仮想化を使うかを指定します。 一つのネットワークの設定ごとに フィールドを指定します。 このように、一つのコンテナに複数のネットワークインターフェースを割り当てることができるだけでなく、同じコンテナに対して複数のネットワーク仮想化の種類を指定することが出来ます。 仮想化の種類は以下の値を取る事が出来ます: ホストのネットワーク名前空間を共有します。 これにより、ホストのネットワークデバイスをコンテナ内で使うことが可能になります。 もしコンテナもホストも init として upstart を使っている場合、(例えば) コンテナ内で 'halt' を実行すると、ホストがシャットダウンしてしまうことにもなります。 ループバックインターフェースだけを作成します。 一方がコンテナに、もう一方が オプションで指定されたブリッジに接続されるペアの仮想イーサネットデバイスを作成します。 もし、ブリッジが指定されていない場合、veth ペアデバイスは作成されますが、ブリッジには接続されません。 ブリッジはコンテナが開始する前にシステムで事前に設定しておく必要があります。 lxc はコンテナ外の設定を扱うことはありません。 デフォルトでは、lxc がコンテナの外部に属するネットワークデバイスに対する名前を決定します。 しかし、もしこの名前を自分で指定したい場合、 オプションを使って名前を設定し、lxc に対して指定をすることができます (非特権コンテナの場合をのぞきます。セキュリティ上の理由からこのオプションは無視されます)。 vlan インターフェースは で指定されたインターフェースとリンクし、コンテナに割り当てられます。 vlan の指定は オプションで指定します。 macvlan インターフェースは により指定されるインターフェースとリンクし、コンテナに割り当てられます。 でモードを指定すると、その macvlan の指定を、同じ上位デバイスで異なる macvlan の間の通信をする時に使います。 指定できるモードは 、、、 のいずれかです。 モードの場合、デバイスは同じ上位デバイスの他のデバイスとの通信を行いません (デフォルト)。 新しい仮想イーサネットポート集約モード (Virtual Ethernet Port Aggregator (VEPA)) である モードの場合、隣接したポートが、ソースとデスティネーションの両方が macvlan ポートに対してローカルであるフレームを全て返すと仮定します。 すなわち、ブリッジが reflective relay として設定されているということです。 上位デバイスから入ってくるブロードキャストフレームは、VEPA モードである全ての macvlan インターフェースに送りつけられます。 ローカルのフレームはローカルには配送されません。 モードの場合、同じポートの異なる macvlan インターフェースの間のシンプルなブリッジとして動作します。 あるインターフェースから他のインターフェースへのフレームは、直接配送され、外部には送出されません。 ブロードキャストフレームは、全ての他のブリッジと外部のインターフェースに対して送られます。 しかし、reflective relay からフレームが返ってきたときは、再度それを配送することはしません。 全ての MAC アドレスを知っているので、ブリッジモジュールのように、macvlan ブリッジモードは学習や STP の必要はありません。 モードの場合、物理インターフェースで受け取った全てのフレームは macvlan インターフェースに転送されます。 モードの場合、ひとつの macvlan インターフェースだけが、ひとつの物理インターフェースに対して設定できます。 で指定された、すでに存在しているインターフェースがコンテナに割り当てられます。 ネットワークに対して行うアクションを指定します。 インターフェースを起動させます。 実際のネットワークトラフィックに使うインターフェースを指定します。 インターフェースに対する MTU を指定します。 インターフェース名は動的に割り当てられます。 しかし、もしコンテナが使用する設定ファイルが一般的な名前を使用するために、他の特定の名前が必要であれば (例えば eth0 など)、コンテナ内のインターフェースは、このオプションで指定した名前にリネームされます。 仮想インターフェースの MAC アドレスは、デフォルトでは動的に割り当てられます。 しかし、MAC アドレスの衝突や、リンクローカルIPv6 アドレスを常に同じにした場合などは、このオプションが必要です。 アドレス中の "x" という文字は、ランダムな値に置き換えられます。 これによりテンプレートに hwaddr を設定することが可能になります。 仮想インターフェースに割り当てる ipv4 アドレスを指定します。 複数行により複数の ipv4 アドレスを指定します。 このアドレスは x.y.z.t/m というフォーマットで指定します。 例えば、192.168.1.123/24。ブロードキャストアドレスも同じ行の ipv4 アドレスのすぐ後で指定しなくてはなりません。 コンテナでゲートウェイとして使う IPv4 アドレスを指定します。 アドレスは x.y.z.t というフォーマットです。 例えば、192.168.1.123。 という特別な値を記述する事も可能です。 これは ( で指定した) ブリッジインターフェースの最初のアドレスを使用し、それをゲートウェイに使うという意味になります。 はネットワークタイプとして と を指定している時だけ有効となります。 仮想インターフェースに割り当てる ipv6 アドレスを指定します。 複数行により複数の ipv6 アドレスを指定します。 このアドレスは x::y/m というフォーマットで指定します。 例えば、2003:db8:1:0:214:1234:fe0b:3596/64。 コンテナでゲートウェイとして使う IPv6 アドレスを指定します。 アドレスは x::y というフォーマットです。例えば、2003:db8:1:0::1。 という特別な値を記述する事も可能です。 これは ( で指定した) ブリッジインターフェースの最初のアドレスを使用し、それをゲートウェイに使うという意味になります。 はネットワークタイプとして と を指定している時だけ有効となります。 ホスト側から使われる、ネットワークの作成と設定が済んだ後に実行するスクリプトを指定します。 以下の引数がスクリプトに渡されます: コンテナ名、設定セクション名(net)。 その後の引数はスクリプトのフックで使われる設定セクションに依存します。 以下がネットワークシステムによって使われます: 実行コンテキスト (up)、ネットワークのタイプ (empty/veth/macvlan/phys) ネットワークのタイプによっては、更に別の引数が渡されるかもしれません: veth/macvlan/phys の場合 (ホスト側の) デバイス名 スクリプトからの標準出力は debug レベルでロギングされます。 標準エラー出力はロギングされません。 しかし、フックの標準エラー出力を標準出力にリダイレクトすることにより保存することは可能です。 ホスト側から使われる、ネットワークを破壊する前に実行するスクリプトを指定します。 以下の引数がスクリプトに渡されます: コンテナ名、設定セクション名(net)。 その後の引数はスクリプトのフックで使われる設定セクションに依存します。 以下がネットワークシステムによって使われます: 実行コンテキスト (up)、ネットワークのタイプ (empty/veth/macvlan/phys)。 ネットワークのタイプによっては、更に別の引数が渡されるかもしれません: veth/macvlan/phys。そして最後に (ホスト側の) デバイス名が渡されます。 スクリプトからの標準出力は debug レベルでロギングされます。 標準エラー出力はロギングされません。 しかし、フックの標準エラー出力を標準出力にリダイレクトすることにより保存することは可能です。 <!-- New pseudo tty instance (devpts) -->新しい擬似端末のインスタンス (devpts) さらに厳しい隔離のために、コンテナは自身のプライベートな pseudo tty (擬似端末) を持つことが可能です。 もし設定された場合、コンテナは新しい pseudo tty インスタンスを持ち、それを自身のプライベートとします。 この値は pts インスタンスに許可される pseudo tty の最大数を指定します (この制限はまだ実装されていません)。 <!-- Container system console -->コンテナのシステムコンソール コンテナでルートファイルシステムを持つように設定されており、inittab ファイルでコンソールの使用が設定されている場合、このコンソールの出力がどこになされるのかを指定したいと思うでしょう。 コンソール出力を書き込むファイルのパスを指定します。 コンソールを割り当てるデバイスのパスを指定します。'none' というキーワードは、単純にコンソールを無効にします。 この設定は、アプリケーションが書き込む事ができるコンソールデバイスファイルが rootfs に存在する場合、メッセージがホスト側に出力されるので危険です。 <!-- Console through the ttys -->tty を通したコンソール このオプションはコンテナが root ファイルシステムを持つように設定されており、inittab ファイルで tty 上に getty の起動が設定されている場合に役に立ちます。 このオプションはコンテナで利用できる tty の数を指定します。 inittab ファイルに設定する getty の数は、このオプションの指定する tty の数より大きくしてはいけません。 さもなければ、超過した分の getty セッションはコンソールか /var/log/messages にうっとうしいメッセージを生死を表示しながら、永久に生死を繰り返すでしょう。 コンテナに作成出来る tty の数を指定します。 <!-- Console devices location -->コンソールデバイスの位置 LXC のコンソールはホストによって作られ、コンテナ内で要求されたデバイスに bind マウントされた Unix98 PTY 経由で提供されます。 デフォルトでは /dev/console と /dev/ttyN に bind マウントされます。 これはゲスト内でのパッケージのアップグレードを妨げる可能性があります。 なので /dev 以下のディレクトリを指定することができます。 LXC はこのディレクトリ以下にファイルを作成し、これらのファイルを bind マウントします。 そして、これらの (作成された) ファイルは /dev/console と /dev/ttyN にシンボリックリンクされます。 シンボリックリンクを消去したり置き換えたりすることは可能ですから、パッケージのアップグレードは成功します。 コンテナのコンソールデバイスを作成するための /dev 以下のディレクトリを指定します。 <!-- /dev directory -->/dev ディレクトリ デフォルトでは、lxc はコンテナの /dev 以下に fd, stdin, stdout, stderr のシンボリックリンクを作成しますが、自動的にはデバイスノードのエントリは作成しません。 これは、コンテナの rootfs で必要な設定を行えるようにするものです。 lxc.autodev が 1 に設定されている場合、コンテナの rootfs をマウントした後、LXC は新しい tmpfs を /dev 以下にマウントします (500k 制限の)。 そして初期デバイスの最小限のセットを作成します。 これは、"systemd" ベースの "init" 環境のコンテナを起動する時に通常必要ですが、他の環境の場合はオプショナルなものです。 コンテナの /dev ディレクトリ内の追加デバイスは フックを使用して作成されます。 コンテナの起動時に LXC が /dev をマウントして最小限の /dev を作成するのを止めるには、この値を 0 に設定してください。 <!-- Enable kmsg symlink -->kmsg のシンボリックリンクの有効化 /dev/console へのシンボリックリンクとして /dev/kmsg を作成することを有効にします。デフォルトは 0 です。 /dev/kmsg へのシンボリックリンクを有効にするには 1 を設定してください。 <!-- Mount points -->マウントポイント マウントポイントセクションは、マウントするための区別された場所を指定します。 これらのマウントポイントは、コンテナだけに見え、コンテナ外で実行されるプロセスから見えることはありません。 例えば、/etc や /var や /home をマウントするときに役に立つでしょう。 注意: 通常 LXC は、マウント対象と相対パス指定のバインドマウントを、適切にコンテナルート以下に閉じ込めます。 これは、ホストのディレクトリやファイルに対して重ね合わせを行うようなマウントによる攻撃を防ぎます。(絶対パス指定のマウントソース中の各パスがシンボリックリンクである場合は無視されます。) しかし、もしコンテナの設定が最初に、/home/joe のようなコンテナユーザのコントロール配下にあるディレクトリを、コンテナ中のある path にマウントし、その後 path 以下でマウントが行われるような場合、コンテナユーザがタイミングを見計らって自身のホームディレクトリ以下でシンボリックリンクを操作するような TOCTTOU 攻撃が成立する可能性があります。 マウント情報の書かれた fstab フォーマットで書かれたファイルの場所を指定します。 マウントする場所は相対バスで書くことができます。そして、ほとんどの場合にコンテナの root からの相対パスとなるはずです。例えば、以下のように書きます。 proc proc proc nodev,noexec,nosuid 0 0 この例は、root ファイルシステムがどこにあっても、コンテナの /proc 以下に proc ファイルシステムをマウントします。 これは、ブロックデバイスがバックエンドのファイルシステムだけでなく、コンテナのクローンにも柔軟に対応できます。 ファイルシステムがイメージファイルやブロックデバイスからマウントされている場合、3 つ目のフィールド (fs_vfstype) は mount 8 のように auto を指定することはできず、明確に指定しなければいけません。 fstab フォーマットの一行と同じフォーマットのマウントポイントの指定をします。 fstab フォーマットに加えて、LXC ではマウントに対して独自の 2 つのオプションが使えます。 は、マウントが失敗しても失敗を返さずに無視します。 と は、マウントポイントをマウントする際にディレクトリもしくはファイルを作成します。 標準のカーネルファイルシステムで自動的にマウントするものを指定します。 これは劇的に設定を容易にする可能性があります。 (or ): /proc を読み書き可能でマウントします。 ただし、/proc/sys と /proc/sysrq-trigger は、セキュリティとコンテナの隔離の目的でリードオンリーで再マウントされます。 : /proc を読み書き可能でマウントします。 (or ): /sys/devices/virtual/net のみ書き込み可能で、その他の /sys はリードオンリーでマウントします。 : /sys を、セキュリティとコンテナの隔離の目的でリードオンリーでマウントします。 : /sys を読み書き可能でマウントします。 : /sys/fs/cgroup を tmpfs でマウントし、そのコンテナの追加が行われた全ての階層構造に対するディレクトリを作製し、その cgroup の名前でその中にサブディレクトリを作製し、そのコンテナ自身の cgroup をそのディレクトリにバインドマウントします。 コンテナは自身の cgroup ディレクトリに書き込みが可能ですが、親ディレクトリはリードオンリーで再マウントされているため書き込めません。 : と同様にマウントされますが、全てリードオンリーでマウントされます。 : と同様にマウントされますが、全て読み書き可能でマウントされます。 コンテナ自身の cgroup に至るまでのパスも書き込み可能になることに注意が必要ですが、cgroup ファイルシステムにはならず、 /sys/fs/cgroup の tmpfs の一部分になるでしょう。 (マウントオプションなしの場合): コンテナが CAP_SYS_ADMIN ケーパビリティを保持している場合、 となります。保持していない場合、 となります。 : /sys/fs/cgroup を tmpfs でマウントし、そのコンテナの追加が行われた全ての階層構造に対するディレクトリを作製し、ホストからコンテナまでの階層構造を全てバインドマウントし、コンテナ自身の cgroup を除いてリードオンリーにします。 と比べると、コンテナ自身の cgroup に至るまでの全てのパスが tmpfs の下層のシンプルなディレクトリとなり、コンテナ自身の cgroup の外ではリードオンリーになりますが、/sys/fs/cgroup/$hierarchy はホストの全ての cgroup 階層構造を含みます。 これにより、コンテナにはかなりの情報が漏洩します。 : と同様にマウントされますが、全てリードオンリーでマウントされます。 : と同様にマウントされますが、全て読み書き可能でマウントされます。 この場合、コンテナは自身の cgroup から脱出する可能性があることに注意してください (コンテナが CAP_SYS_ADMIN を持ち、自身で cgroup ファイルシステムをマウント可能なら、いずれにせよそのようにするかもしれないことにも注意してください)。 (マウントオプションなしの場合): コンテナが CAP_SYS_ADMIN ケーパビリティを保持している場合、 となります。保持していない場合、 となります。 cgroup 名前空間が有効の場合、 の自動マウントの指定はどれも無視されます。これは、コンテナが自身でファイルシステムをマウントするため、自動マウントがコンテナの init を混乱させる可能性があるためです。 cgroup ファイルシステムの自動マウントが有効の場合、/sys/fs/cgroup 以下の tmpfs は常に読み書き可能でマウントされることに注意が必要です (しかし と の場合は、個々の階層の /sys/fs/cgroup/$hierarchy は読み込み専用となるでしょう)。これは Ubuntu の mountall 8 コマンドの特異な動きに対処するためのものです。特異な動きとは、/sys/fs/cgroup が読み込み専用でマウントされた状態で、コンテナが CAP_SYS_ADMIN を持たない場合、/sys/fs/cgroup を読み書き可能で再マウントしようとしてできないため、コンテナのブート時にユーザからの入力を待ってしまうというものです。 例: lxc.mount.auto = proc sys cgroup lxc.mount.auto = proc:rw sys:rw cgroup-full:rw <!-- Root file system -->ルートファイルシステム コンテナのルートファイルシステムは、ホストのルートファイルシステムと異なるようにすることも可能です。 コンテナのルートファイルシステムを指定します。 この値はイメージファイル、ディレクトリ、ブロックデバイスのどれかを取ることができます。 もし指定されない場合、コンテナはホストとルートファイルシステムを共有します。 ディレクトリ、単純なブロックデバイスのバックエンドを持つコンテナの場合、パス名を使うことができます。 もし rootfs が nbd デバイスの場合、nbd:file:1 という指定は file を nbd デバイスとして使用し、その 1 番目のパーティションが rootfs としてマウントされます。 nbd:file という指定は、nbd デバイス自身をマウントします。 overlayfs:/lower:/upper という指定は、rootfs は /lower という読み込み専用でマウントされるディレクトリの上に、/upper というディレクトリを読み書き可能で重ね合わせてマウントします。 aufs:/lower:/upper は overlayfs で指定している部分を aufs と指定すれば同じことになります。overlayfs と aufs は両方とも、複数の /lower ディレクトリを指定できます。 loop:/file は /file を loop デバイスとして使用し、loop デバイスをマウントします。 root ファイルシステムの変更の前に、 を再帰的にどこにバインドするのかを指定します。これは pivot_root 8 システムコールが確実に成功する事を保証します。 どんなディレクトリでも良く、デフォルトでも通常は動くはずです。 rootfs をマウントするときに追加したいマウントオプション。 使用するバックエンドのタイプを、例えば 'dir' や 'zfs' のように指定します。 コンテナ起動時に LXC が推測できますが、時間がかかります。これを指定すると、余分な処理を避けられます。 Control group CONTROL GROUP セクションは、(lxc とは) 別のサブシステムの設定を含みます。 lxc は、このサブシステム名の正しさはチェックしません。 実行時のエラーを検出するのに不便ですが、別の将来のサブシステムをサポート出来るという有利な点もあります。 設定する control group の値を指定します。 サブシステム名は、control group のそのままの名前です。 許される名前や値の書式は LXC が指示することはなく、コンテナが実行された時に実行されている Linux カーネルの機能に依存します。 例えば <!-- Capabilities -->ケーパビリティ コンテナが root 権限で実行されていても、コンテナ内ではケーパビリティ (capabilities) を削除する事は可能です。 コンテナ内で削除するケーパビリティ (capability) を指定します。 一行でスペース区切りで複数のケーパビリティを指定することも可能です。 指定は、"CAP_" というプレフィックスなしで、小文字でケーパビリティを指定します。 例えば、CAP_SYS_MODULE というケーパビリティは sys_module と指定する必要があります。 詳しくは以下を参照してください。 capabilities 7 この設定を、値を指定しない状態で使った場合、それ以前に指定された削除対象のケーパビリティの指定をすべてクリアします (lxc.cap.drop に何も指定しない状態になります)。 コンテナ内で維持するケーパビリティを指定します。指定した以外の全てのケーパビリティはドロップされます。 特別な値 "none" が指定されている時点で、lxc はこの時点で保持することになっている全てのケーパビリティをクリアします。"none" を単独で使用するとすべてのケーパビリティを削除できます。 <!-- Apparmor profile -->Apparmor プロファイル lxc が apparmor サポートでコンパイルされ、インストールされている場合で、ホストで apparmor が有効な場合、コンテナが従って動くべき apparmor プロファイルは、コンテナの設定で指定することが可能です。 デフォルトは、ホストのカーネルで cgroup 名前空間が使える場合は lxc-container-default-cgnsです。使えない場合は lxc-container-default です。 コンテナが従うべき apparmor プロファイルを指定します。 コンテナが apparmor による制限を受けないように設定するには、以下のように設定します。 lxc.aa_profile = unconfined もし apparmor プロファイルが変更されないままでなくてはならない場合 (ネストしたコンテナである場合や、すでに confined されている場合) は以下のように設定します。 lxc.aa_profile = unchanged apparmor プロファイルはパス名ベースですので、多数のファイルの制限を行う際、執念深い攻撃者に対して効果的であるためにはマウントの制限が必要です。 しかし、これらのマウントの制限は upstream のカーネルではまだ実装されていません。マウントの制限なしでも、apparmor プロファイルによって予想外のダメージに対する保護が可能です。 このフラグが 0 の場合 (デフォルト)、カーネルが apparmor のマウント機能をサポートしていない場合にコンテナが起動しません。これはカーネルを更新した後に機能が退行したことが検出できるようにするためです。 不完全な apparmor の保護の下でコンテナを起動するためには、このフラグを 1 に設定してください。 <!-- SELinux context -->SELinux コンテキスト lxc が SELinux サポートでコンパイルされ、インストールされている場合で、ホストで SELinux が有効な場合、コンテナが従って動くべき SELinux コンテキストは、コンテナの設定で指定することが可能です。 デフォルトは unconfined_t であり、これは lxc がコンテキストを変えないという意味になります。 ポリシーの例と追加の情報は @DATADIR@/lxc/selinux/lxc.te ファイルを参照してください。 コンテナが従うべき SELinux コンテキストを指定するか、unconfined_t を指定します。例えば以下のように設定します。 lxc.se_context = system_u:system_r:lxc_t:s0:c22 <!-- Seccomp configuration -->Seccomp の設定 コンテナは、起動時に seccomp プロファイルをロードすることで、利用可能なシステムコールを減らして起動することが可能です。 seccomp の設定ファイルは、1 行目がバージョン番号、2 行目がポリシーのタイプで始まる必要があり、その後に設定を書きます。 現時点では、バージョン番号は 1 と 2 をサポートしています。バージョン 1 では、ポリシーはシンプルなホワイトリストですので、2 行目は "whitelist" でなければなりません。 そして残りの行には 1 行に 1 つずつ、システムコール番号を書きます。各行のシステムコール番号がホワイトリスト化され、リストにない番号は、そのコンテナではブラックリストに入ります。 バージョン 2 では、ポリシーはブラックリストもしくはホワイトリストで表され、ルールごとのアクションと、ポリシーごとのデフォルトのアクションを設定できます。そして、アーキテクチャごとの設定と、テキストで書かれたシステムコール名での設定が可能です。 以下にブラックリストのポリシーの例を示します。これは mknod 以外の全てのシステムコールが許可され、mknod が呼ばれると、何もせずに単に 0(成功) を返します。 2 blacklist mknod errno 0 コンテナがスタートする前にロードする seccomp の設定を含むファイルを指定します。 <!-- UID mappings -->UID のマッピング コンテナは、ユーザとグループの id のマッピングを持った専用のユーザ名前空間で起動することが可能です。 たとえば、コンテナ内のユーザ id 0 を、ホストのユーザ id 200000 にマッピングすることが可能です。 コンテナの root ユーザはコンテナ内では特権を持ちますが、ホストでは特権を持ちません。 通常は、システムコンテナは id の範囲を要求し、それをマッピングします。 例えば、コンテナ内のユーザとグループの id 0 から 20,000 を 200,000 から 220,000 にマッピングします。 4 つの値を記述する必要があります。 最初の文字は 'u' か 'g' のどちらかで、ユーザかグループの ID のどちらをマッピングするかを指定します。 次はコンテナのユーザ名前空間内に現れる最初のユーザ ID です。 その次は、そのユーザ ID のホスト上での値です。 最後は、ID のマッピングをいくつ連続して行うかの数を指定します。 <!-- Container hooks -->コンテナのフック コンテナのフックは、コンテナの存続期間の色々な場面で実行することのできるプログラムやスクリプトです。 コンテナのフックが実行されるとき、情報がコマンドライン引数と環境変数の両方を通して渡されます。引数は: コンテナ名 セクション (常に 'lxc') フックのタイプ ('clone' や 'pre-mount' など) 追加の引数。clone フックの場合、lxc-clone に渡される追加の引数は、フックへの引数として追加されます。stop フックの場合は、コンテナの名前空間のそれぞれに対するファイルディスクリプタへのパスが、名前空間名とともに渡されます。 以下の環境変数がセットされます。 LXC_NAME: コンテナ名 LXC_ROOTFS_MOUNT: マウントされた root ファイルシステムへのパス LXC_CONFIG_FILE: コンテナの設定ファイルのパス LXC_SRC_NAME: clone フックの場合、元のコンテナの名前 LXC_ROOTFS_PATH: コンテナの lxc.rootfs エントリ。これはマウントされた rootfs が存在する場所にはならないでしょう。それには LXC_ROOTFS_MOUNT を使用してください。 スクリプトからの標準出力は debug レベルでロギングされます。 標準エラー出力はロギングされません。 しかし、フックの標準エラー出力を標準出力にリダイレクトすることにより保存することは可能です。 コンテナの tty、コンソールの作成、マウントが実行される前に、ホストの名前空間内で実行するフック。 コンテナのファイルシステムの名前空間で実行されますが、rootfs が設定される前に実行するフック。 これにより rootfs の操作が可能になります。 例えば、暗号化されたファイルシステムのマウントなどです。 このフック内でなされるマウントはホストには影響しません (mounts propagation を除いて)。 なので、それらはコンテナがシャットダウンする時に自動的にクリーンアップされます。 マウントが完了した後ですが、pivot_root の前にコンテナの名前空間で実行されるフック。 == 1 が設定されている場合で、マウントが完了し、マウント時のフックも実行された後ですが、pivot_root の前にコンテナの名前空間で実行するフック。 このフックの目的は、systemd ベースのコンテナ向けの autodev オプションが設定されている時に、コンテナの /dev ディレクトリを設定するのを支援することです。コンテナの /dev ディレクトリは、このフックが実行される時有効な ${} 環境変数からの相対パスとなります。 コンテナの init が実行される直前にコンテナの名前空間で実行されるフック。 コンテナ内で利用可能なプログラムである必要があります。 コンテナのシャットダウン後、コンテナの名前空間への参照とともに、ホストの名前空間で実行されるフックです。 それぞれの名前空間に対応する追加の引数がフックに渡されます。その引数にはコロンで区切られた名前空間のタイプ名とファイル名が含まれており、ファイル名は名前空間に対するファイルディスクリプタを取得するのに使えます。 タイプ名は /proc/PID/ns ディレクトリ内のファイル名です。 例えば、マウント名前空間に対応する引数は通常は mnt:/proc/PID/fd/12 のようになります。 コンテナがシャットダウンされた後にホストの名前空間で実行するフック。 コンテナが新しいコンテナにクローンされる際に実行されるフック。詳しくは lxc-clone 1 を参照してください。 コンテナを破壊する際に実行されるフックです。 <!-- Container hooks Environment Variables -->コンテナのフックで使える環境変数 起動時のフックに設定情報を提供し、フックの機能を助けるための環境変数がいくつか利用可能です。 全ての変数が全てのコンテキストで利用可能なわけではありません。 具体的には、全てのパスはホストシステム上のパスであり、そのため、 フックの時点では使用できません。 LXC コンテナの名前。共通のログ環境内でのログメッセージに使うときに便利です。[] コンテナの設定ファイルのホスト上でのパス。 これは、他の方法では得られない追加の設定情報を見つけるために、コンテナに、元の、トップレベルの設定ファイルの位置を与えるものです。 [] 設定されている場合のコンテナのコンソール出力のパス。 [] [] 設定されている場合のコンテナのコンソールログ出力のパス。 [] 初期にコンテナがマウントされる場所。 これは、コンテナインスタンスが起動するためのコンテナの rootfs へのホスト上のパスであり、インスタンスのための移行が行われる場所です。 [] rootfs.mount へマウントされるコンテナのルートへのホスト上のパスです。 [] clone フックの場合のみ使われます。クローン元のコンテナ名が設定されます。 stop フックの場合のみ使われます。コンテナのシャットダウンの場合は "stop"、リブートの場合は "reboot" が設定されます。 この変数が設定されていない場合、お使いのバージョンの LXC は cgroup 名前空間を扱えません。設定されている場合、この値は 1 に設定されています。そして、cgroup 名前空間を扱えます。 この変数はカーネルで cgroup 名前空間が有効であることは保証しません。この変数は lxcfs のマウントフックが使います。 <!-- Logging -->ロギング ロギングはコンテナごとに設定することが可能です。 デフォルトでは、lxc パッケージのコンパイル条件に依存し、コンテナのスタートアップは ERROR レベルでのみロギングされ、コンテナのパス以下か、@LOGPATH@ 以下のどちらかにコンテナ名 (の後に '.log' が付与される) をもとにした名前でロギングされます。 デフォルトのログレベルとログファイルは両方とも、コンテナの設定ファイル内で指定され、デフォルトの値を上書きします。 同様に、設定ファイルのエントリは lxc-start のコマンドラインオプションで上書きすることも可能です。 ログを取得するレベル。 ログレベルは 0..8 の範囲の整数です。 数字が小さいほど冗長なデバッグを意味します。 具体的には、0 = trace, 1 = debug, 2 = info, 3 = notice, 4 = warn, 5 = error, 6 = critical, 7 = alert, and 8 = fatal です。 指定されない場合、レベルのデフォルトは 5 (error) で、それ以上のエラーがロギングされます。 (フックスクリプトやネットワークインターフェースの起動、停止時のスクリプトのような) スクリプトが呼ばれた時、スクリプトの標準出力は level 1 の debug でロギングされます。 ログ情報を書き込むファイル。 <!-- Autostart -->自動起動 自動起動オプションでは、自動起動させるコンテナと順番の設定が可能です。 このオプションは LXC ツールが直接使用するか、ディストリビューションが提供する外部ツールが使用するかもしれません。 コンテナを自動起動させるかどうかを設定します。 有効な値は 0(オフ) か 1(オン) です。 コンテナを起動させた後、次のコンテナを起動させるまでにどれくらい (秒) 待つかを設定します。 多数の自動起動させるコンテナがある場合のコンテナの起動順を決めるのに使う整数を指定します。 この値が 0 でない場合、コンテナが初期化される前 (pre-start フックが実行される前) にマウント名前空間がホストから unshare されます。この機能を使う場合、スタート時に CAP_SYS_ADMIN ケーパビリティが必要です。デフォルト値は 0 です。 コンテナを追加したいコンテナグループ名を指定します。 複数の値を設定でき、複数回指定することもできます。 設定されたグループは、関連する一連のコンテナを起動させるために使われます。 <!-- Autostart and System Boot -->自動起動とシステムブート コンテナはいくつでもグループに属することができ、全く属さないことも可能です。特別なグループが 2 つ存在します。1 つは NULL グループです。これはどのグループにも属さないコンテナです。もう 1 つは "onboot" グループです。 LXC サービスが有効になった状態でシステムがブートすると、最初に "onboot" グループのメンバーである lxc.start.auto == 1 が設定されたコンテナを起動しようとします。起動は lxc.start.order の順に起動します。 lxc.start.delay が指定されている場合、現在対象となっているコンテナに初期化の時間を与え、ホストシステムの負荷を低減するために、次のコンテナを開始させるまでに遅延時間を与えます。 "onboot" グループのメンバーが開始した後、LXC システムは lxc.start.auto == 1 が設定された、どのグループのメンバーでもない (NULL グループの) コンテナのブートを onboot グループのコンテナと同様に開始します。 <!-- Container Environment -->コンテナの環境変数 コンテナに環境変数を渡したい場合 (環境変数はコンテナの init とその子孫全てで利用可能です)、lxc.environment パラメータがその用途に使えます。 機微 (センシティブ) な情報を渡さないように注意が必要です。そのような情報を持たないコンテナ内のプロセスでこれらの環境変数が利用可能になってしまいます。環境変数は常に /proc/PID/environ 経由で利用可能になります。 この設定項目は、設定したい環境変数ごとに 1 度ずつ、何度でも指定できます。 コンテナに渡したい環境変数を指定します。 例: lxc.environment = APP_ENV=production lxc.environment = SYSLOG_SERVER=192.0.2.42 <!-- Examples -->例 以下に紹介するいくつかの例に加えて、他の設定例が @DOCDIR@/examples にあります。 <!-- Network -->ネットワーク この設定は、片方をブリッジである br0 と接続される veth ペアデバイスを使うコンテナを設定します (ブリッジは管理者によりあらかじめシステム上に設定済みである必要があります)。 仮想ネットワークデバイスは、コンテナ内では eth0 とリネームされます。 lxc.utsname = myhostname lxc.network.type = veth

<!-- UID/GID mapping -->UID/GID のマッピング この設定は、コンテナ内のユーザとグループ両方の id 0-9999 の範囲を、ホスト上の 100000-109999 へマッピングします。 lxc.id_map = u 0 100000 10000 lxc.id_map = g 0 100000 10000 Control group この設定は、アプリケーションのための control group をいくつか設定します。 cpuset.cpus は定義された cpu のみ使用できるように制限します。 cpus.share は、control group の (cpu) 優先度を指定します。 devices.allow は、特定のデバイスを使用可能にします。 lxc.cgroup.cpuset.cpus = 0,1 lxc.cgroup.cpu.shares = 1234 lxc.cgroup.devices.deny = a lxc.cgroup.devices.allow = c 1:3 rw lxc.cgroup.devices.allow = b 8:0 rw <!-- Complex configuration -->複雑な設定 この例は、control group

コピータイプのクローンは元のコンテナから新しいコンテナへ root ファイルシステムをコピーします。 スナップショットファイルシステムは、バッキングストアのスナップショット機能を使い、元のコンテナの非常に小さな copy-on-write でのスナップショットを作製します。 スナップショットでのクローンは、新しいコンテナのバッキングストアとしてスナップショット機能のサポートが必要になります。 現時点では、このようなバッキングストアとしては aufs, btrfs, lvm, overlayfs, zfs のみをサポートします。 LVM デバイスはスナップショットのスナップショットはサポートしていません。 新しいコンテナのバッキングストアは、オーバーレイタイプのコンテナを除いては元のコンテナのタイプと同じになります。 ディレクトリバックエンドのコンテナのスナップショットを aufs

新しいコンテナで元のコンテナと違うバッキングストアを使う場合のバッキングストアを選択します。 デフォルトでは元のコンテナと同じものが使われます。 現時点では、バッキングストアの変更は、ディレクトリバックエンドのコンテナに対する aufs と overlayfs のスナップショットに対してのみサポートされます。 有効なバッキングストアは dir(directory), aufs, btrfs,

オブジェクトは、アプリケーションが使用したり、参照したりする様々なリソースの定義です。 設定ファイルがより多くの情報を持つほど、コンテナやアプリケーションはより隔離されたものになります。 設定ファイルが config_file で指定されない場合、コンテナはデフォルトの隔離状態で作られます: プロセス、sysv ipc、マウントポイントです。 <!-- Options -->オプション コンテナの仮想化と隔離機能を設定するための設定ファイルを指定します。 template は lxc-create コマンドが呼び出す、存在する 'lxc-template' スクリプトの短い名前です。 例えば、busybox, debian, fedora, ubuntu, sshd があります。 期待されるスクリプトの構造の詳細は、@LXCTEMPLATEDIR@ 内の例を参照してください。

@LXCPATH@/container/rootfs 以下のディレクトリであることを意味します。 'dir' にはオプションとして --dir ROOTFS を指定することも可能です。 このオプションは、デフォルトの代わりに特定のパス以下にコンテナの rootfs を置くということになります。 ('none' は 'dir' のエイリアスです。) 'btrfs' が指定された場合、ターゲットのファイルシステムは btrfs でなければいけません。 そして、コンテナの rootfs は新しい subvolume として作製されます。 このことにより、スナップショットによるクローンが作製可能になりますが、結果として rsync --one-filesystem が、別々のファイルシステムとして取り扱ってしまうことにもなります。 backingstore が 'lvm' である場合、lvm ブロックデバイスを使用します。 この時、以下のオプションが有効になります: --lvname lvname1 はデフォルト値のコンテナ名の LV の代わりに lvname1 という名前の LV を作成します。 --vgname vgname1 は、デフォルト値である lxc という volume group の代わりに vgname1 という名前の volume group 内に LV を作成します。 --thinpool thinpool1 は、デフォルトである lxc のという名前のプールの代わりに thinpool1 という名前のプール内にシンプロビジョニングされたボリュームとして LV を作成します。 --fstype FSTYPE は LV 上のファイルシステムをデフォルト値である ext4 の代わりに FSTYPE で指定したもので作成します。 --fssize SIZE はデフォルト値である 1G の代わりに SIZE で指定したサイズで LV を作成します。 backingstore が 'loop' の場合、'lvm' と同様に --fstype FSTYPE と --fssize SIZE が使えます。これらの値のデフォルト値は 'lvm' の場合と同じです。 backingstore が 'rbd' の場合、ceph.conf に有効な設定がされており、ceph.client.admin.keyring が定義されている必要があります。 --rbdname RBDNAME を指定すると、RBDNAME という名前のブロックデバイスを作成します。このオプションを指定しない場合のデフォルトのブロックデバイス名はコンテナ名です。 --rbdpool POOL を指定すると、POOL という名前のプール内にブロックデバイスを作成します。このオプションを指定しない場合のデフォルトのプール名は 'lxc' です。 backingstore が 'best' の時、lxc は btrfs, zfs, lvm, dir の順に試行します。 これは template-options で指定したものをオプションとしてテンプレートへ渡します。

Options The uid map to use in the user namespace. Each map consists of four colon-separate values. First a character 'u', 'g' or 'b' to specify whether this map pertains to user ids, group ids, or both; next the first userid in the user namespace; next the first userid as seen on the host; and finally the number of ids to be mapped. More than one map can be specified. If no map is specified, then by default the full uid and gid ranges granted by /etc/subuid and /etc/subgid will be mapped to the uids and gids starting at 0 in the container. Note that lxc-usernsexec always tries to setuid and setgid to 0 in the namespace. Therefore uid 0 in the namespace must be mapped. Examples To spawn a shell with the full allotted subuids mapped into the container, use lxc-usernsexec To run a different shell than /bin/sh, use lxc-usernsexec -- /bin/bash If your user id is 1000, root in a container is mapped to 190000, and you wish to chown a file you own to root in the container, you can use: lxc-usernsexec -m b:0:1000:1 -m b:1:190000:1 -- /bin/chown 1:1 $file This maps your userid to root in the user namespace, and 190000 to uid 1. Since root in the user namespace is privileged over all userids mapped into the namespace, you are allowed to change the file ownership, which you could not do on the host using a simple chown. &seealso; Author Serge Hallyn serge.hallyn@ubuntu.com lxc-2.0.7/doc/lxc-ls.sgml.in0000644061062106075000000001473513041440472012510 00000000000000 ]> @LXC_GENERATE_DATE@ lxc-ls 1 lxc-ls list the containers existing on the system lxc-ls -1 --active --frozen --running --stopped -f -F format -g groups --nesting=NUM --filter=regex Description lxc-ls list the containers existing on the system.

Description LXC configuration is split in two parts. Container configuration and system configuration. Container configuration The container configuration is held in the config stored in the container's directory. A basic configuration is generated at container creation time with the default's recommended for the chosen template as well as extra default keys coming from the default.conf file. That default.conf file is either located at @LXC_DEFAULT_CONFIG@ or for unprivileged containers at ~/.config/lxc/default.conf. Details about the syntax of this file can be found in: lxc.container.conf 5 System configuration The system configuration is located at @LXC_GLOBAL_CONF@ or ~/.config/lxc/lxc.conf for unprivileged containers. This configuration file is used to set values such as default lookup paths and storage backend settings for LXC.

Ok, without warranty, here are the commands to launch a shell inside a container with a predefined configuration template, it may work. @BINDIR@/lxc-execute -n foo -f @DOCDIR@/examples/lxc-macvlan.conf /bin/bash Overview The container technology is actively being pushed into the mainstream linux kernel. It provides the resource management through the control groups aka process containers and resource isolation through the namespaces. The linux containers, lxc, aims to use these new functionalities to provide a userspace container object which provides full resource isolation and resource control for an applications or a system. The first objective of this project is to make the life easier for the kernel developers involved in the containers project and especially to continue working on the Checkpoint/Restart new features. The lxc is small enough to easily manage a container with simple command lines and complete enough to be used for other purposes. Requirements The lxc relies on a set of functionalities provided by the kernel which needs to be active. Depending of the missing functionalities the lxc will work with a restricted number of functionalities or will simply fail. The following list gives the kernel features to be enabled in the kernel to have the full features container: * General setup * Control Group support -> Namespace cgroup subsystem -> Freezer cgroup subsystem -> Cpuset support -> Simple CPU accounting cgroup subsystem -> Resource counters -> Memory resource controllers for Control Groups * Group CPU scheduler -> Basis for grouping tasks (Control Groups) * Namespaces support -> UTS namespace -> IPC namespace -> User namespace -> Pid namespace -> Network namespace * Device Drivers * Character devices -> Support multiple instances of devpts * Network device support -> MAC-VLAN support -> Virtual ethernet pair device * Networking * Networking options -> 802.1d Ethernet Bridging * Security options -> File POSIX Capabilities The kernel version >= 2.6.32 shipped with the distros, will work with lxc, this one will have less functionalities but enough to be interesting. The helper script lxc-checkconfig will give you information about your kernel configuration. The control group can be mounted anywhere, eg: mount -t cgroup cgroup /cgroup. It is however recommended to use cgmanager, cgroup-lite or systemd to mount the cgroup hierarchy under /sys/fs/cgroup. Functional specification A container is an object isolating some resources of the host, for the application or system running in it. The application / system will be launched inside a container specified by a configuration that is either initially created or passed as parameter of the starting commands. How to run an application in a container ? Before running an application, you should know what are the resources you want to isolate. The default configuration is to isolate the pids, the sysv ipc and the mount points. If you want to run a simple shell inside a container, a basic configuration is needed, especially if you want to share the rootfs. If you want to run an application like sshd, you should provide a new network stack and a new hostname. If you want to avoid conflicts with some files eg. /var/run/httpd.pid, you should remount /var/run with an empty directory. If you want to avoid the conflicts in all the cases, you can specify a rootfs for the container. The rootfs can be a directory tree, previously bind mounted with the initial rootfs, so you can still use your distro but with your own /etc and /home Here is an example of directory tree for sshd: [root@lxc sshd]$ tree -d rootfs rootfs |-- bin |-- dev | |-- pts | `-- shm | `-- network |-- etc | `-- ssh |-- lib |-- proc |-- root |-- sbin |-- sys |-- usr `-- var |-- empty | `-- sshd |-- lib | `-- empty | `-- sshd `-- run `-- sshd and the mount points file associated with it: [root@lxc sshd]$ cat fstab /lib /home/root/sshd/rootfs/lib none ro,bind 0 0 /bin /home/root/sshd/rootfs/bin none ro,bind 0 0 /usr /home/root/sshd/rootfs/usr none ro,bind 0 0 /sbin /home/root/sshd/rootfs/sbin none ro,bind 0 0 How to run a system in a container ? Running a system inside a container is paradoxically easier than running an application. Why ? Because you don't have to care about the resources to be isolated, everything need to be isolated, the other resources are specified as being isolated but without configuration because the container will set them up. eg. the ipv4 address will be setup by the system container init scripts. Here is an example of the mount points file: [root@lxc debian]$ cat fstab /dev /home/root/debian/rootfs/dev none bind 0 0 /dev/pts /home/root/debian/rootfs/dev/pts none bind 0 0 More information can be added to the container to facilitate the configuration. For example, make accessible from the container the resolv.conf file belonging to the host. /etc/resolv.conf /home/root/debian/rootfs/etc/resolv.conf none bind 0 0 Container life cycle When the container is created, it contains the configuration information. When a process is launched, the container will be starting and running. When the last process running inside the container exits, the container is stopped. In case of failure when the container is initialized, it will pass through the aborting state. Configuration The container is configured through a configuration file, the format of the configuration file is described in lxc.conf 5 Creating / Destroying container (persistent container) A persistent container object can be created via the lxc-create command. It takes a container name as parameter and optional configuration file and template. The name is used by the different commands to refer to this container. The lxc-destroy command will destroy the container object. lxc-create -n foo lxc-destroy -n foo Volatile container It is not mandatory to create a container object before to start it. The container can be directly started with a configuration file as parameter. Starting / Stopping container When the container has been created, it is ready to run an application / system. This is the purpose of the lxc-execute and lxc-start commands. If the container was not created before starting the application, the container will use the configuration file passed as parameter to the command, and if there is no such parameter either, then it will use a default isolation. If the application is ended, the container will be stopped also, but if needed the lxc-stop command can be used to kill the still running application. Running an application inside a container is not exactly the same thing as running a system. For this reason, there are two different commands to run an application into a container: lxc-execute -n foo [-f config] /bin/bash lxc-start -n foo [-f config] [/bin/bash] lxc-execute command will run the specified command into the container via an intermediate process, lxc-init. This lxc-init after launching the specified command, will wait for its end and all other reparented processes. (to support daemons in the container). In other words, in the container, lxc-init has the pid 1 and the first process of the application has the pid 2. lxc-start command will run directly the specified command into the container. The pid of the first process is 1. If no command is specified lxc-start will run the command defined in lxc.init_cmd or if not set, /sbin/init . To summarize, lxc-execute is for running an application and lxc-start is better suited for running a system. If the application is no longer responding, is inaccessible or is not able to finish by itself, a wild lxc-stop command will kill all the processes in the container without pity. lxc-stop -n foo Connect to an available tty If the container is configured with the ttys, it is possible to access it through them. It is up to the container to provide a set of available tty to be used by the following command. When the tty is lost, it is possible to reconnect it without login again. lxc-console -n foo -t 3 Freeze / Unfreeze container Sometime, it is useful to stop all the processes belonging to a container, eg. for job scheduling. The commands: lxc-freeze -n foo will put all the processes in an uninteruptible state and lxc-unfreeze -n foo will resume them. This feature is enabled if the cgroup freezer is enabled in the kernel. Getting information about container When there are a lot of containers, it is hard to follow what has been created or destroyed, what is running or what are the pids running into a specific container. For this reason, the following commands may be useful: lxc-ls lxc-info -n foo lxc-ls lists the containers of the system. lxc-info gives information for a specific container. Here is an example on how the combination of these commands allows one to list all the containers and retrieve their state. for i in $(lxc-ls -1); do lxc-info -n $i done Monitoring container It is sometime useful to track the states of a container, for example to monitor it or just to wait for a specific state in a script. lxc-monitor command will monitor one or several containers. The parameter of this command accept a regular expression for example: lxc-monitor -n "foo|bar" will monitor the states of containers named 'foo' and 'bar', and: lxc-monitor -n ".*" will monitor all the containers. For a container 'foo' starting, doing some work and exiting, the output will be in the form: 'foo' changed state to [STARTING] 'foo' changed state to [RUNNING] 'foo' changed state to [STOPPING] 'foo' changed state to [STOPPED] lxc-wait command will wait for a specific state change and exit. This is useful for scripting to synchronize the launch of a container or the end. The parameter is an ORed combination of different states. The following example shows how to wait for a container if he went to the background. Setting the control group for container The container is tied with the control groups, when a container is started a control group is created and associated with it. The control group properties can be read and modified when the container is running by using the lxc-cgroup command. lxc-cgroup command is used to set or get a control group subsystem which is associated with a container. The subsystem name is handled by the user, the command won't do any syntax checking on the subsystem name, if the subsystem name does not exists, the command will fail. lxc-cgroup -n foo cpuset.cpus will display the content of this subsystem. lxc-cgroup -n foo cpu.shares 512 will set the subsystem to the specified value. Bugs The lxc is still in development, so the command syntax and the API can change. The version 1.0.0 will be the frozen version. &seealso; Author Daniel Lezcano daniel.lezcano@free.fr lxc-2.0.7/doc/lxc.container.conf0000644061062106075000000000250013041440472013416 00000000000000# the fstab mount file lxc.mount = ./fstab # the hostname to be set into the container lxc.utsname = virtnode # The network has several of kind of configuration: # # * veth : the network will use the veth virtual device, the specified # link must be a bridge # * macvlan : the network will use the macvlan device, the specified link # should be an existing interface, usually it is eth0 # * phys : the network will use a physical network device, the specified # link should be an existing interface lxc.network.type = macvlan # specify the flags to be used for the network, actually only is allowed # which mean the network should be set up when created.

It will consult the configuration file @LXC_USERNIC_CONF@ to determine the number of interfaces which the calling user is allowed to create, and which bridge he may attach them to. It tracks the number of interfaces each user has created using the file @LXC_USERNIC_DB@. It ensures that the calling user is privileged over the network namespace to which the interface will be attached. Options The process id for the task to whose network namespace the interface should be attached. The network interface type to attach. Currently only veth is supported. With this type, two interfaces representing each tunnel endpoint are created. One endpoint will be attached to the specified bridge, while the other will be passed into the container. The bridge to which to attach the network interface, for instance lxcbr0. The desired interface name in the container. This will be eth0 if unspecified.

Description @LXC_USERNIC_CONF@ controls the limits which the program lxc-user-nic places on network interfaces which an unprivileged user may create. Configuration This file consists of multiple entries, one per line, of the form: user type bridge number or @group type bridge number Where is the username to whom this entry applies. is the groupname to which this entry applies. is the type of network interface being allowed. Only veth is currently supported. is the bridge to which the network interfaces may be attached, for instance lxcbr0. is the number or quota of network interfaces of the given type which the given user or group may attach to the given bridge, for instance 2. Since a user can be specified both by username as well as one or more usergroups, it is possible that several configuration lines enable that user to create network interfaces. In such cases, any interfaces create are counted towards the quotas of the user or group in the order in which they appear in the file. If the quota of one line is full, the rest will be parsed until one is found or the end of the file.

The available tty are free slots taken by this command. That means if the container has four ttys available and the command has been launched four times each taking a different tty, the fifth command will fail because no console will be available. The command will connect to a tty. If the connection is lost or broken, the command can be launched again and regain the tty at the state it was before the disconnection. A ttynum of 0 may be given to attach to the container's /dev/console instead of its dev/tty<ttynum>. A keyboard escape sequence may be used to disconnect from the tty and quit lxc-console. The default escape sequence is <Ctrl+a q>. Options Specify the escape sequence prefix to use instead of <Ctrl a>. This may be given as '^letter' or just 'letter'. For example to use <Ctrl+b q> as the escape sequence use -e '^b'. Specify the tty number to connect to or 0 for the console. If not specified the next available tty number will be automatically chosen by the container. &commonoptions; Diagnostic tty service denied No tty is available or there is not enough privilege to use the console. For example, the container belongs to user "foo" and "bar" is trying to open a console to it. &seealso; Author Daniel Lezcano daniel.lezcano@free.fr lxc-2.0.7/doc/api/0000755061062106075000000000000013041440546010636 500000000000000lxc-2.0.7/doc/api/Doxyfile0000644061062106075000000030211213041440472012261 00000000000000# Doxyfile 1.8.5 # This file describes the settings to be used by the documentation system # doxygen (www.doxygen.org) for a project. # # All text after a double hash (##) is considered a comment and is placed in # front of the TAG it is preceding. # # All text after a single hash (#) is considered a comment and will be ignored. # The format is: # TAG = value [value, ...] # For lists, items can also be appended using: # TAG += value [value, ...] # Values that contain spaces should be placed between quotes (\" \"). #--------------------------------------------------------------------------- # Project related configuration options #--------------------------------------------------------------------------- # This tag specifies the encoding used for all characters in the config file # that follow.
