Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with "bug" is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with "feature" is open to whoever wants to implement it.

Write Documentation

stacker could always use more documentation, whether as part of the official stacker docs, in docstrings, or even on the web in blog posts, articles, and such.

Note: We use Google style docstrings (http://sphinxcontrib-napoleon.readthedocs.io/en/latest/example\_google.html)

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/cloudtools/stacker/issues.

If you are proposing a feature:

  • Explain in detail how it would work.
  • Keep the scope as narrow as possible, to make it easier to implement.
  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here's how to set up stacker for local development.

  1. Fork the stacker repo on GitHub.

  2. Clone your fork locally:

    $ git clone [email protected]:your_name_here/stacker.git
  3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:

    $ mkvirtualenv stacker
    $ cd stacker/
    $ python setup.py develop
  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you can make your changes locally.

  5. When you're done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:

    $ make test

    To get flake8 just pip install it into your virtualenv.

  6. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
  7. Submit a pull request through the GitHub website.

For information about the functional testing suite, see tests/README.md.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.
  2. If the pull request adds functionality, the docs should be updated. (See Write Documentation above for guidelines)
  3. The pull request should work for Python 2.7 and for PyPy. Check https://circleci.com/gh/cloudtools/stacker and make sure that the tests pass for all supported Python versions.
  4. Please update the Upcoming/Master section of the CHANGELOG with a small bullet point about the change.
