Contributing to Pinniped

Pinniped is better because of our contributors and maintainers. It is because of you that we can bring great software to the community.

Contributions to Pinniped are welcome. Here are some things to help you get started.

Code of Conduct

Please see the Code of Conduct.

Project Scope

See SCOPE.md for some guidelines about what we consider in and out of scope for Pinniped.

Roadmap

The near-term and mid-term roadmap for the work planned for the project maintainers is documented in ROADMAP.md.

Discussion

Got a question, comment, or idea? Please don't hesitate to reach out via GitHub Discussions, GitHub Issues, or in the Kubernetes Slack Workspace within the #pinniped channel. Join our Google Group to receive updates and meeting invitations.

Issues

Need an idea for a project to get started contributing? Take a look at the open issues. Also check to see if any open issues are labeled with "good first issue" or "help wanted".

Bugs

To file a bug report, please first open an issue. The project team will work with you on your bug report.

Once the bug has been validated, a pull request can be opened to fix the bug.

For specifics on what to include in your bug report, please follow the guidelines in the issue and pull request templates.

Features

To suggest a feature, please first open an issue and tag it with proposal, or create a new Discussion. The project maintainers will work with you on your feature request.

Once the feature request has been validated, a pull request can be opened to implement the feature.

For specifics on what to include in your feature request, please follow the guidelines in the issue and pull request templates.

Reporting security vulnerabilities

Please follow the procedure described in SECURITY.md.

CLA

We welcome contributions from everyone, but we can only accept them if you sign our Contributor License Agreement (CLA). If you would like to contribute and you have not signed it, our CLA-bot will walk you through the process when you open a Pull Request. For questions about the CLA process, see the FAQ or submit a question through the GitHub issue tracker.

Learning about Pinniped

New to Pinniped?

• Start here to learn how to install and use Pinniped: Learn to use Pinniped for federated authentication to Kubernetes clusters
• Start here to learn how to navigate the source code: Code Walk-through
• Other more detailed documentation can be found at: Pinniped Docs

Building

The Dockerfile at the root of the repo can be used to build and package the server-side code. After making a change to the code, rebuild the docker image with the following command.

# From the root directory of the repo...
docker build .

The Pinniped CLI client can be built for local use with the following command.

# From the root directory of the repo...
go build -o pinniped ./cmd/pinniped

Testing

Running Lint

./hack/module.sh lint

Running Unit Tests

./hack/module.sh units

Running Integration Tests

1. Install dependencies:

   • docker
   • htpasswd (installed by default on MacOS, usually found in apache2-utils package for linux)
   • kapp
   • kind
   • kubectl
   • ytt
   • nmap
   • openssl (installed by default on MacOS)
   • Chrome

   On macOS, these tools can be installed with Homebrew (assuming you have Chrome installed already):

   brew install kind vmware-tanzu/carvel/ytt vmware-tanzu/carvel/kapp kubectl nmap && brew cask install docker
   

2. Create a kind cluster, compile, create container images, and install Pinniped and supporting test dependencies using:

   ./hack/prepare-for-integration-tests.sh
   

3. Run the Pinniped integration tests:

   ulimit -n 512 && source /tmp/integration-test-env && go test -v -count 1 -timeout 0 ./test/integration
   

   To run specific integration tests, add the -run flag to the above command to specify a regexp for the test names. Use a leading / on the regexp because the Pinniped integration tests are automatically nested under several parent tests (see integration/main_test.go). For example, to run an integration test called TestE2E, add -run /TestE2E to the command shown above.

4. After making production code changes, recompile, redeploy, and run tests again by repeating the same commands described above. If there are only test code changes, then simply run the tests again.

To destroy the local Kubernetes cluster, run ./hack/kind-down.sh.

Observing Tests on the Continuous Integration Environment

CI will not be triggered on a pull request until the pull request is reviewed and approved for CI by a project maintainer. Once CI is triggered, the progress and results will appear on the Github page for that pull request as checks. Links will appear to view the details of each check.

Documentation

Any pull request which adds a new feature or changes the behavior of any feature which was previously documented should include updates to the documentation. All documentation lives in this repository. This project aspires to follow the Kubernetes documentation style guide.

Pre-commit Hooks

This project uses pre-commit to agree on some conventions about whitespace/file encoding.

$ brew install pre-commit
[...]
$ pre-commit install
pre-commit installed at .git/hooks/pre-commit

Becoming a Pinniped Maintainer

Regular contributors who are active in the Pinniped community and who have contributed at least several significant pull requests may be considered for promotion to become a maintainer upon request. Please contact an existing maintainer if you would like to be considered.
