Contributing to Compose

Compose is a part of the Docker project, and follows the same rules and principles. Take a read of Docker's contributing guidelines to get an overview.

TL;DR

Pull requests will need:

Development environment

If you're looking contribute to Compose but you're new to the project or maybe even to Python, here are the steps that should get you started.

  1. Fork https://github.com/docker/compose to your username.
  2. Clone your forked repository locally git clone git@github.com:yourusername/compose.git.
  3. Enter the local directory cd compose.
  4. Set up a development environment by running python setup.py develop. This will install the dependencies and set up a symlink from your docker-compose executable to the checkout of the repository. When you now run docker-compose from anywhere on your machine, it will run your development version of Compose.

Running the test suite

$ script/test

Building binaries

Linux:

$ script/build-linux

OS X:

$ script/build-osx

Note that this only works on Mountain Lion, not Mavericks, due to a bug in PyInstaller.

Release process

  1. Open pull request that:
  • Updates the version in compose/__init__.py
  • Updates the binary URL in docs/install.md
  • Updates the script URL in docs/completion.md
  • Adds release notes to CHANGES.md

  1. Create unpublished GitHub release with release notes

  2. Build Linux version on any Docker host with script/build-linux and attach to release

  3. Build OS X version on Mountain Lion with script/build-osx and attach to release as docker-compose-Darwin-x86_64 and docker-compose-Linux-x86_64.

  4. Publish GitHub release, creating tag
