How to Contribute

We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.

Submitting changes

We would like ask you to fork Kapitan project and create a Pull Request targeting master branch. All submissions, including submissions by project members, require review.

Setting up environment

We highly recommend that you create a dedicated Python environment for Kapitan. There are multiple solutions:

Once you've done it, please install all Kapitan's dependencies:

pip3 install -r requirements.txt

Because we are using a pinned version of reclass which is added as a submodule into Kapitan's repository, you need to pull it separately by executing the command below:

git submodule update --init

Testing

Run make test to run all tests. If you modify anything in the examples/ folder make sure you replicate the compiled result of that in tests/test_kubernetes_compiled. If you add new features, run make test_coverage to make sure the test coverage remains at current or better levels.

If you would like to evaluate your changes by running your version of Kapitan, you can do that by running bin/kapitan from this repository or even setting an alias to it.

Code Style

Try to fix warnings from make codestyle before submitting to make sure you adhere to the Style Guide for Python (PEP8).

Releasing

  • Create a branch named release-v<NUMBER>. Use v0.*.*-rc.* if you want pre-release versions to be uploaded.
  • Update CHANGELOG.md with the release changes.
  • Once reviewed and merged, Travis will auto-release.
  • The merge has to happen with a merge commit not with squash/rebase so that the commit message still mentions deepmind/release-v* inside.

Updating gh-pages docs

We use mkdocs to generate our gh-pages from .md files under docs/ folder.

Updating our gh-pages is therefore a two-step process.

1. Update the .md files

Submit a PR for our master branch that updates the .md file(s). Test how the changes would look like when deployed to gh-pages by serving it on localhost:

# from project root
pip install mkdocs mkdocs-material pymdown-extensions markdown-include
mkdocs build
mkdocs serve
# open http://127.0.0.1:8000

2. Submit a PR for gh-pages branch to deploy the update

Once the above PR has been merged, use mkdocs gh-deploy command to push the commit that updates the site content to your own gh-pages branch. Make sure that you already have this gh-pages branch in your fork that is up-to-date with our gh-pages branch such that the two branches share the commit history (otherwise Github would not allow PRs to be created).

# locally, on master branch (which has your updated docs)
mkdocs gh-deploy -m "Commit message" -f ./mkdocs.yml -b gh-pages

After it's pushed, create a PR that targets our gh-pages branch from your gh-pages branch.
