Chapter 25. Working with Helm charts

Note

Certify your container application component before proceeding with Red Hat Helm chart certification. All the containers referenced in a Helm chart component must already be certified and published on the Red Hat Ecosystem Catalog before certifying a Helm chart component.

25.1. Introduction to Helm charts

Helm is a Kubernetes-native automation technology and software package manager that simplifies deployment of applications and services. Helm uses a packaging format called charts. A chart is a collection of files that describe a related set of Kubernetes resources. A running instance of a specific version of the chart in a cluster is called a release. A new release is created every time a chart is installed on the cluster. Each time a chart is installed, or a release is upgraded or rolled back, an incremental revision is created. Charts go through an automated Red Hat OpenShift certification workflow, which guarantees security compliance as well as best integration and experience with the platform.

25.2. Certification workflow for Helm charts

Note

Red Hat recommends that you are a Red Hat Certified Engineer or hold equivalent experience before starting the certification process.

Task Summary

The certification workflow includes three primary steps-

  1. Section 25.2.1, “Certification on-boarding for Helm charts”
  2. Section 25.2.2, “Certification testing for Helm charts”
  3. Section 25.2.3, “Publishing the certified Helm chart on the Red Hat Ecosystem Catalog”

25.2.1. Certification on-boarding for Helm charts

Perform the steps outlined for certification onboarding:

  1. Join the Red Hat Connect for Technology Partner Program.
  2. Agree to the program terms and conditions.

  3. Create your product listing by selecting your desired product category. You can select from the available product categories:

    1. Containerized Application
    2. Standalone Application
    3. OpenStack Infrastructure
  4. Complete your company profile.
  5. Add components to the product listing.
  6. Certify components for your product listing.

25.2.2. Certification testing for Helm charts

Follow these high-level steps to run a certification test:

  1. Fork the Red Hat upstream repository.
  2. Install and run the chart verifier tool on your test environment.
  3. Review the test results and troubleshoot, if any issues.
  4. Submit the certification results to Red Hat through a pull request.

25.2.3. Publishing the certified Helm chart on the Red Hat Ecosystem Catalog

Certified helm charts are published on the Product Listings page of the Red Hat partner connect portal, which you can then run on a supported Red Hat container platform. Your product along with its Helm chart gets listed on the Red Hat Container Catalog using the listing information that you provide.
