2021-03-05 4.3 is a small release that should mostly improve behavior when things are going wrong, especially when endpoints are unavailable and clients are still trying to talk to them.

2019-04-01 - Add `--redirect-to` option to specify destination port when redirecting http to https with `--redirect-from`. - Add health check endpoint at `/_chp_healthz`. - Docker base image is updated to `node/10-alpine` from `node/6-alpine` - Dependencies are updated via Renovate ## 4.0 ### [4.0.0] - 2018-10-12 - Add support for client SSL certificates for encrypting proxied requests. - Update all nodejs dependencies. Most significant is updating winston (logging) from 2 to 3. There is no longer a global logger, instead use `this.log`. - Drop support for node 4. Minimum node version is 6. - Support CONFIGPROXY_SSL_KEY_PASSPHRASE env for setting the passphrase of ssl keys (API_SSL for api ssl key). ## [3.1] ### [3.1.1] - 2018-01-15 - Fix a bug when using the new custom storage backend support where the body of requests could be lost. ### [3.1.0] - 2017-11-03 3.1 adds two new features: - Add `--change-origin` passthrough for node-http-proxy's changeOrigin option. - Add support via `--storage-backend ` for custom storage classes. See [configurable-http-proxy-redis-backend](https://github.com/globocom/configurable-http-proxy-redis-backend) for an example using redis. ## [3.0] ### [3.0.0] - 2017-09-19 3.0 is a major release because much of the code has been reorganized to adopt some javascript standards: - Use ES6 and Promises instead of ES5 and callbacks, which we can do without a compiler because CHP 2.0 required nodejs < 4. - auto-format code with prettify (run `npm run fmt` to auto-format your code after making changes). There shouldn't be any major changes in 3.0, but marking it as a major upgrade because there could be regressions introduced by the restructuring. Fixes: - Fix routing of `/prefix?query` where a query parameter was passed exactly on the routing prefix with no trailing slash. Improvements: - Quieter messages for ECONNREFUSED and ECONNRESET, which are generally not indicative of problems, but rather common events of peers disconnecting during a request. - The docker image for `jupyterhub/configurable-http-proxy` is now based on `node:6-alpine`. ## [2.0] ### 2.0.4 - 2017-06-21 - Add logging of all API requests ### 2.0.3 - 2017-06-12 - Fix docker image entrypoint, broken in 2.0.2 ### 2.0.2 - 2017-06-07 - Fix error raised trying to `setHeader` on an undefined response (e.g. when encountering socket-level error) ### 2.0.1 **Important** CHP 2.0.0 drops support for node.js ≤ 4.0. **Added:** - Add configuration option for proxy timeout `--proxy-timeout , Timeout (in millis) when proxy receives no response from target.` [\#86](https://github.com/jupyterhub/configurable-http-proxy/pull/86) - Add configuration options for auto rewrite and protocol rewrite [\#73](https://github.com/jupyterhub/configurable-http-proxy/pull/73): - `--auto-rewrite, Rewrite the Location header host/port in redirect responses` - `--protocol-rewrite ', Rewrite the Location header protocol in redirect responses to the specified protocol` - Add low-level code for separate stores of routes to enable future support of other data stores such as Redis [\#81](https://github.com/jupyterhub/configurable-http-proxy/pull/81) **Changed:** - Support only LTS releases and above for NodeJS [\#82](https://github.com/jupyterhub/configurable-http-proxy/pull/82). This means only ≥ 4.0 are supported. **Fixed:** - Fix behavior to correctly handle children when a parent node is deleted [\#93](https://github.com/jupyterhub/configurable-http-proxy/pull/93) - Fix closure reference when serving custom error pages [\#91](https://github.com/jupyterhub/configurable-http-proxy/pull/91) - Improved all-interfaces warning message when `ip='*'` [\#94](https://github.com/jupyterhub/configurable-http-proxy/pull/94) ## [1.3] ### [1.3.1] - 2016-10-12 - small fixes for node 6 support - fix `--no-x-forward` again (for real, this time) ### [1.3.0] - 2016-08-01 - add `--ssl-protocol`, so that one can restrict to TLS, e.g. `--ssl-protocol=TLSv1` - fix handling of ``--no-x-forward` ## [1.2] - 2016-04-19 - add statsd support ## [1.1] - 2016-01-04 - add `--ssl-request-cert` args for certificate-based client authentication - fix some SSL parameters that were ignored for API requests ## [1.0] - 2016-01-04 - add `ConfigProxy.proxy_request` event, for customizing requests as the pass through the proxy. - add more ssl-related options for specifying options on the CLI. - fix regression in 0.5 where deleting a top-level route would also delete the default route. ## [0.5] - 2015-10-05 - add `--error-target` for letting another http server render error pages. Server must handle `/404` and `/503` URLs. - add `--error-path` for custom static HTML error pages. `[CODE].html` will be used if it exists, otherwise `error.html`. - fix bug preventing root route from being deleted ## [0.4] - 2015-10-02 - add `--redirect-port` for automatically redirecting a common port to the correct one (e.g. redirecting http to https) ## [0.3] - 2015-04-29 - fixes for URL escaping - add host-based routing ## [0.2.1] - 2014-11-21 ## [0.2.0] - 2014-11-14 ## [0.1.1] - 2014-10-01 [unreleased]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.5.0...HEAD [4.5.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.4.4...4.5.0 [4.4.4]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.3.2...4.4.4 [4.3.2]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.3.1...4.3.2 [4.3.1]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.3.0...4.3.1 [4.3.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.2.3...4.3.0 [4.2.3]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.2.2...4.2.3 [4.2.2]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.2.1...4.2.2 [4.2.1]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.2.0...4.2.1 [4.2.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.1.0...4.2.0 [4.1.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/4.0.1...4.1.0 [4.0.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/3.1.1...4.0.1 [3.1.1]: https://github.com/jupyterhub/configurable-http-proxy/compare/3.1.0...3.1.1 [3.1]: https://github.com/jupyterhub/configurable-http-proxy/compare/3.0.0...3.1.0 [3.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/2.0.4...3.0.0 [2.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/1.3.1...2.0.4 [1.3]: https://github.com/jupyterhub/configurable-http-proxy/compare/1.2.0...1.3.0 [1.2]: https://github.com/jupyterhub/configurable-http-proxy/compare/1.1.0...1.2.0 [1.1]: https://github.com/jupyterhub/configurable-http-proxy/compare/1.0.0...1.1.0 [1.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/0.5.0...1.0.0 [0.5]: https://github.com/jupyterhub/configurable-http-proxy/compare/0.4.0...0.5.0 [0.4]: https://github.com/jupyterhub/configurable-http-proxy/compare/0.3.0...0.4.0 [0.3]: https://github.com/jupyterhub/configurable-http-proxy/compare/0.2.1...0.3.0 [0.2.1]: https://github.com/jupyterhub/configurable-http-proxy/compare/0.2.0...0.2.1 [0.2.0]: https://github.com/jupyterhub/configurable-http-proxy/compare/0.1.1...0.2.0 configurable-http-proxy-4.5.0/CONTRIBUTING.md000066400000000000000000000003001407527146400205500ustar00rootroot00000000000000# Contributing Welcome!

It is a simple wrapper around [node-http-proxy][]. node-http-proxy is an HTTP programmable proxying library that supports websockets and is suitable for implementing components such as reverse proxies and load balancers. By wrapping node-http-proxy, **configurable-http-proxy** extends this functionality to [JupyterHub] deployments. ## Table of Contents - [Install](#install) - [Usage](#usage) - [Starting the proxy](#starting-the-proxy) - [Setting a default target](#setting-a-default-target) - [Command-line options](#command-line-options) - [Using the REST API](#using-the-rest-api) - [REST API Basics](#REST-api-basics) - [Authenticating via passing a token](#authenticating-via-passing-a-token) - [Getting the routing table](#getting-the-routing-table) - [Adding new routes](#adding-new-routes) - [Deleting routes](#deleting-routes) - [Custom error pages](#custom-error-pages) - [Host-based routing](#host-based-routing) - [Troubleshooting](#troubleshooting) ## Install Prerequisite: [Node.js](https://nodejs.org/en/download/) ≥ 12 If you're installing `configurable-http-proxy` in Linux, you can follow [the instruction of nodesource](https://github.com/nodesource/distributions#installation-instructions) to install arbitrary version of Node.js. To install the `configurable-http-proxy` package globally using npm: ```bash npm install -g configurable-http-proxy ``` To install from the source code found in this GitHub repo: ```bash git clone https://github.com/jupyterhub/configurable-http-proxy cd configurable-http-proxy npm install # Use 'npm install -g' for global install ``` [**Return to top**][] ## Usage The configurable proxy runs two HTTP(S) servers: - The **public-facing interface** to your application (controlled by `--ip`, `--port`) - listens on **all interfaces** by default. - The **inward-facing REST API** (`--api-ip`, `--api-port`) - listens on localhost by default - The REST API uses token authorization, where the token is set in the `CONFIGPROXY_AUTH_TOKEN` environment variable. ![](./doc/_static/chp.png) [**Return to top**][] ### Starting the proxy ```bash configurable-http-proxy [options] ``` where `[options]` are the command-line options described below. [**Return to top**][] ### Setting a default target The **default target** is used when a client has requested a URL for which there is no routing target found in the proxy table. To set a **default target**, pass the command line option, `--default-target`, when starting the configurable proxy: ```bash configurable-http-proxy --default-target=proto://host[:port] ``` For example: ```bash configurable-http-proxy --default-target=http://localhost:8888 ``` [**Return to top**][] ### Command-line options ``` Usage: configurable-http-proxy [options] Options: -V, --version output the version number --ip Public-facing IP of the proxy --port (defaults to 8000) Public-facing port of the proxy --ssl-key SSL key to use, if any --ssl-cert SSL certificate to use, if any --ssl-ca SSL certificate authority, if any --ssl-request-cert Request SSL certs to authenticate clients --ssl-reject-unauthorized Reject unauthorized SSL connections (only meaningful if --ssl-request-cert is given) --ssl-protocol Set specific SSL protocol, e.g. TLSv1_2, SSLv3 --ssl-ciphers `:`-separated ssl cipher list.

Defaults to in-MemoryStore. -h, --help display help for command ``` [**Return to top**][] ## Using the REST API The configurable-http-proxy REST API is documented and available as: - a nicely rendered, interactive version at the [petstore swagger site][] - a [swagger specification file][] in this repo [**Return to top**][] ### REST API Basics **API Root** | HTTP method | Endpoint | Function | | ----------- | -------- | -------- | | GET | /api/ | API Root | **Routes** | HTTP method | Endpoint | Function | | ----------- | ------------------------ | ----------------------------------- | | GET | /api/routes | [Get all routes in routing table][] | | POST | /api/routes/{route_spec} | [Add a new route][] | | DELETE | /api/routes/{route_spec} | [Remove the given route][] | [**Return to top**][] ### Authenticating via passing a token The REST API is authenticated via passing a token in the `Authorization` header. The API is served under the `/api/routes` base URL. For example, this `curl` command entered in the terminal passes this header `"Authorization: token $CONFIGPROXY_AUTH_TOKEN"` for authentication and retrieves the current routing table from this endpoint, `http://localhost:8001/api/routes`: ```bash curl -H "Authorization: token $CONFIGPROXY_AUTH_TOKEN" http://localhost:8001/api/routes ``` [**Return to top**][] ### Getting the routing table **Request:** GET /api/routes[?inactive_since=ISO8601-timestamp] **Parameters:** `inactive_since`: If the `inactive_since` URL parameter is given as an [ISO8601](http://en.wikipedia.org/wiki/ISO_8601) timestamp, only routes whose `last_activity` is earlier than the timestamp will be returned. The `last_activity` timestamp is updated whenever the proxy passes data to or from the proxy target. **Response:** _Status code_ status: 200 OK _Response body_ A JSON dictionary of the current routing table. This JSON dictionary _excludes_ the default route. **Behavior:** The current routing table is returned to the user if the request is successful. [**Return to top**][] ### Adding new routes POST requests create new routes. The body of the request should be a JSON dictionary with at least one key: `target`, the target host to be proxied. **Request:** POST /api/routes/[:path] **Required input:** `target`: The host URL Example request body: ```json { "target": "http://localhost:8002" } ``` **Response:** status: 201 Created **Behavior:** After adding the new route, any request to `/path/prefix` on the proxy's public interface will be proxied to `target`. [**Return to top**][] ### Deleting routes **Request:** DELETE /api/routes/[:path] **Response:** status: 204 No Content **Behavior:** Removes a route from the proxy's routing table. [**Return to top**][] ## Custom error pages Custom error pages can be provided when the proxy encounters an error and has no proxy target to handle a request. There are two typical errors that CHP may hit, along with their status code: - 404 error: Returned when a client has requested a URL for which there is no routing target. This error **can be prevented** by setting a [`default target`][] before starting the configurable-http-proxy. - 503 error: Returned when a route exists, but the upstream server isn't responding. This is more common, and can be due to any number of reasons, including the target service having died, not finished starting, or network instability. [**Return to top**][] ### Setting the path for custom error pages When starting the CHP, specify an error path `--error-path /usr/share/chp-errors` to the location of the error page: ```bash configurable-http-proxy --error-path /usr/share/chp-errors ``` When a proxy error occurs, CHP will look in the following location for a custom html error page to serve: /usr/share/chp-errors/{CODE}.html where `{CODE}` is a status code number for an html page to serve. If there is a 503 error, CHP will look for a custom error page in this location `/usr/share/chp-errors/503.html`. If no custom error html file exists for the error code, CHP will use the default `error.html`. If you specify an error path, **make sure** you also create a default `error.html` file. [**Return to top**][] ### Setting a target for custom error handling You can specify a target URL to use when errors occur by setting `--error-target {URL}` when starting the CHP. If, for example, CHP starts with `--error-target http://localhost:1234`, and the proxy encounters an error, the proxy will make a GET request to the `error-target` server. The GET request will be sent to the `error-target` server URL, `http://localhost:1234`, appending the status code `/{CODE}`, and passing the failing request's URL escaped in a URL parameter: GET /404?url=%2Fescaped%2Fpath [**Return to top**][] ## Host-based routing If the CHP is started with the `--host-routing` option, the proxy will use the hostname of the incoming request to select a target. When using host-based routes, the API uses the target in the same way as if the hostname were the first part of the URL path, e.g.: ```python { "/example.com": "https://localhost:1234", "/otherdomain.biz": "http://10.0.1.4:5555", } ``` [**Return to top**][] ## Troubleshooting Q: My proxy is not starting. What could be happening? - If this occurs on Ubuntu/Debian, check that the you are using a recent version of node. Some versions of Ubuntu/Debian come with a version of node that is very old, and it is necessary to update node to a recent or `LTS` version.

The Docker image is automatically built and published on changes to the git repository as is configured [here](https://hub.docker.com/repository/docker/jupyterhub/configurable-http-proxy/builds). To make a tagged release follow the instructions below, but first make sure you meet the prerequisites: - To have push rights to the [configurable-http-proxy GitHub repository](https://github.com/jupyterhub/configurable-http-proxy). - To have [Node.js](https://nodejs.org) installed. ## Steps to make a release 1. Update [CHANGELOG.md](CHANGELOG.md) if it is not up to date, and verify [README.md](README.md) has an updated output of running `--help`. Make a PR to review the CHANGELOG notes. 1. Once the changelog is up to date, checkout the main branch and make sure it is up to date and clean. ```bash ORIGIN=${ORIGIN:-origin} # set to the canonical remote, e.g. 'upstream' if 'origin' is not the official repo git checkout main git branch --set-upstream-to=$ORIGIN/main main git pull ``` 1. Update the version with [`npm version`](https://docs.npmjs.com/cli/v6/commands/npm-version) and let it make a git commit and tag as well for us. ```bash # specify the new version here, # which should already have been chosen when updating the changelog. npm version 1.2.3 # verify changes git diff HEAD~1 ``` 1. Reset the version to the next development version with `npm version`, without creating a tag: ```bash npm version --no-git-tag-version prerelease --preid=dev git commit -am "back to dev" # verify changes git diff HEAD~1 ``` 1. Push your new tag and commits to GitHub. ```bash git push --follow-tags $ORIGIN main ``` 1. Verify [the automated workflow](https://github.com/jupyterhub/configurable-http-proxy/actions?query=workflow%3A%22Publish+to+npm%22) succeeded. ## Manual release to npm A manual release should not generally be required, but might be needed in the event of a problem in the automated publishing workflow. 1. Verify you are a collaborator of the [npmjs project](https://www.npmjs.com/package/configurable-http-proxy). 1. Checkout the git tag. ``` git checkout ``` 1. Cleanup old node_modules etc. ``` git clean -xfd ``` 1. Publish to NPM. ```bash npm login npm publish ``` configurable-http-proxy-4.5.0/bin/000077500000000000000000000000001407527146400170765ustar00rootroot00000000000000configurable-http-proxy-4.5.0/bin/configurable-http-proxy000077500000000000000000000327711407527146400236320ustar00rootroot00000000000000#!/usr/bin/env node // // cli entrypoint for starting a Configurable Proxy // // Copyright (c) Jupyter Development Team. // Distributed under the terms of the Modified BSD License. // "use strict"; var fs = require("fs"), pkg = require("../package.json"), cli = require("commander"), tls = require("tls"), winston = require("winston"); cli .version(pkg.version) .option("--ip ", "Public-facing IP of the proxy") .option("--port (defaults to 8000)", "Public-facing port of the proxy", parseInt) .option("--ssl-key ", "SSL key to use, if any") .option("--ssl-cert ", "SSL certificate to use, if any") .option("--ssl-ca ", "SSL certificate authority, if any") .option("--ssl-request-cert", "Request SSL certs to authenticate clients") .option( "--ssl-reject-unauthorized", "Reject unauthorized SSL connections (only meaningful if --ssl-request-cert is given)" ) .option("--ssl-protocol ", "Set specific SSL protocol, e.g. TLSv1_2, SSLv3") .option("--ssl-ciphers ", "`:`-separated ssl cipher list.
