## Issues

Need an idea for a project to get started contributing? Take a look at the open
[issues](https://github.com/vmware-tanzu/pinniped/issues).
Also check to see if any open issues are labeled with
["good first issue"](https://github.com/vmware-tanzu/pinniped/labels/good%20first%20issue)
or ["help wanted"](https://github.com/vmware-tanzu/pinniped/labels/help%20wanted).

### Bugs

To file a bug report, please first open an
[issue](https://github.com/vmware-tanzu/pinniped/issues/new?template=bug_report.md). The project team
will work with you on your bug report.

Once the bug has been validated, a [pull request](https://github.com/vmware-tanzu/pinniped/compare)
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](https://github.com/vmware-tanzu/pinniped/issues/new?template=feature-proposal.md)
and tag it with `proposal`, or create a new [Discussion](https://github.com/vmware-tanzu/pinniped/discussions).
The project team will work with you on your feature request.

Once the feature request has been validated, a [pull request](https://github.com/vmware-tanzu/pinniped/compare)
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.

## 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](https://cla.vmware.com/faq) or submit a question through the GitHub issue
tracker.

## Building

The [Dockerfile](Dockerfile) at the root of the repo can be used to build and
package the code. After making a change to the code, rebuild the docker image with the following command.

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

## Testing

### Running Lint

```bash
./hack/module.sh lint
```

### Running Unit Tests

```bash
./hack/module.sh units
```

### Running Integration Tests

1. Install dependencies:

   - [`chromedriver`](https://chromedriver.chromium.org/) (and [Chrome](https://www.google.com/chrome/))
   - [`docker`](https://www.docker.com/)
   - `htpasswd` (installed by default on MacOS, usually found in `apache2-utils` package for linux)
   - [`kapp`](https://carvel.dev/#getting-started)
   - [`kind`](https://kind.sigs.k8s.io/docs/user/quick-start)
   - [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
   - [`tilt`](https://docs.tilt.dev/install.html)
   - [`ytt`](https://carvel.dev/#getting-started)

   On macOS, these tools can be installed with [Homebrew](https://brew.sh/) (assuming you have Chrome installed already):

   ```bash
   brew install kind tilt-dev/tap/tilt k14s/tap/ytt k14s/tap/kapp kubectl chromedriver && brew cask install docker
   ```

1. Create a local Kubernetes cluster using `kind`:

   ```bash
   ./hack/kind-up.sh
   ```

1. Install Pinniped and supporting dependencies using `tilt`:

   ```bash
   ./hack/tilt-up.sh
   ```

   Tilt will continue running and live-updating the Pinniped deployment whenever the code changes.

1. Run the Pinniped integration tests:

   ```bash
   source /tmp/integration-test-env && go test -v -count 1 ./test/integration
   ```

To uninstall the test environment, run `./hack/tilt-down.sh`.
To destroy the local Kubernetes cluster, run `./hack/kind-down.sh`.

### Observing Tests on the Continuous Integration Environment

[CI](https://hush-house.pivotal.io/teams/tanzu-user-auth/pipelines/pinniped-pull-requests)
will not be triggered on a pull request until the pull request is reviewed and
approved for CI by a project [maintainer](MAINTAINERS.md). Once CI is triggered,
the progress and results will appear on the Github page for that
[pull request](https://github.com/vmware-tanzu/pinniped/pulls) 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](https://kubernetes.io/docs/contribute/style/style-guide).

## Pre-commit Hooks

This project uses [pre-commit](https://pre-commit.com/) to agree on some conventions about whitespace/file encoding.

```bash
$ 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](MAINTAINERS.md) if you would like to be considered.
