AI Lab Helm Charts

This project is a collection of helm charts, insipired by the AI Software Templates.

Gitops

The gitops component, handled by ArgoCD for the RHDH case, is replaced by a Kubernetes Job created by the Helm chart, where this Job:

• Creates the GitHub repository for the application.
• Copies the application source code into the new repository.
• Copies the Tekton PipelineRun that builds new images for the application after pull requests merge or commits are pushed directly to the main branch, and then updates the Deployment of the application with the new version of the image by directly patching the Deployment via oc, vs. ArgoCD using gitops to patch the Deployment.
• Commits these changes and pushes the commit to the preferred branch of the new repository.

The source code is here.

OpenShift Pipelines

For OpenShift Pipelines configuration the two Helm charts provided are:

• The Pipeline Install Helm Chart that makes Cluster Administrative level changes to OpenShift Pipelines to make sure that:
  • OpenShift Pipelines Operator is installed.
  • The correct Tekton Pipelines features are configured for our purposes.
  • The Pipelines As Code component is set up with the requisite credentials to process GitHub events for you GitHub Application.
• The Pipeline Setup Helm Chart that makes the User/Tenant changes in your application Namespace:
  • The Pipelines As Code PipelinesRuns in your Namespace have the requisite credentials to push your application's image to your Quay repository.
  • The Gitops component has the requisite credentials to interact with the GitHub repository for your application.

The ai-lab helm charts exclusively uses tekton pipelines and tasks under rhdh-pipelines repo. The only customized resource used for the helm chart case is:

• The .tekton/docker-push.yaml PipelineRun used to manage push events received from the github app webhook.

Testing with a Custom Helm Repository

Release Process

The ai-lab-helm-charts are created on demand.

• A tag should be created with the version of the release as the name. ai-lab-helm-charts follows the v{major}.{minor}.{bugfix} format (e.g v0.1.0).
• Before proceeding, make sure that all the version fields within Chart.yaml have this tag as the value. For example in the case where the tag is v0.1.0, the version should be 0.1.0.
• After the new release is published, the updated Helm packages will be pinned on the release.
