Contributing to podtato-head

The purpose of podtato-head is to enable infrastructure and platform architects and engineers to try, compare, and contrast many options for delivering apps and their components to a Kubernetes cluster.

Please keep this in mind as you develop new contributions! To make it easy for architects to try, compare and contrast, make sure the docs and tests for your delivery tool are similar to existing ones.

Contribute a new delivery tool or service

To add a delivery tool or service to the repo, please create an issue to discuss and a PR with proposed changes. Each tool should get its own directory under ./delivery with a README.md; look at existing tools and write something similar. Please also add a test for your tool in .github/workflows/build.yaml (a GitHub actions descriptor) following existing examples.

README details

Include details in README.md to help architects and engineers trying the tool, such as the following:

  • Describe how to set up or deploy the tools or services. Please provide something compatible with "local" clusters provided by kind, minikube, etc.
  • Describe how to set up the tool or service to deliver the podtato-head application. If you make modifications from the base manifests and charts describe them.
  • Describe how to actually deliver the podtato-head application.
  • Describe how to verify the delivery and verify functionality of the delivered app.
  • Describe how to upgrade to a new version using the tool, and/or how to rollback.
  • Describe how to completely purge the podtato-head app and the delivery tools and services from the cluster. Some folks need to return their cluster to a pristine state!

Other suggestions

  • Provide a command line script to run all the example steps which users can copy and paste. You may use this as part of your test too. The following bash commands work as they echo then execute a command: 
    if [ $command -eq onboard ] 
    echo command_to_execute
    command to execute
fi
  • Provide links to the tool's home page, issues page, and source repo. Help people find resources for their questions.
  • If you have a video walkthrough of the example - great!

Contribute to the podtato-head app

If you have a new use cases in mind (e.g. adding an additonal service, ....) please create an issue and describe how the use case should work. As we want to keep the main branch as a working version we will create a dedicated branch for new use cases.
