Chapter 18. Working with Operators

Note

Certify your operator image or necessary container image as a container application project before proceeding with Red Hat Operator certification. All containers referenced in an Operator Bundle must already be certified and published in the Red Hat Ecosystem Catalog prior to beginning to certify an Operator Bundle.

18.1. Introduction to Operators

A Kubernetes operator is a method of packaging, deploying, and managing a Kubernetes application. Our Operator certification program ensures that the partner’s operator is deployable by the Operator Lifecycle Manager on the OpenShift platform and is formatted properly, using Red Hat certified container images.

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 18.2.1, “Certification on-boarding”
  2. Section 4.2, “Certification testing”
  3. Section 18.2.3, “Publishing the certified Operator on the Red Hat Ecosystem Catalog”

18.2.1. Certification on-boarding

Perform the steps outlined for the certification on-boarding:

  1. Join the Red Hat Connect for Technology Partner Program.
  2. Add a software product to certify.
  3. Fill in your company profile.
  4. Complete the pre-certification checklist.
  5. Create an OpenShift Operator project bundle for your product.

18.2.2. Certification testing
Copy link

To run the certification test:

  1. Fork the Red Hat upstream repository.
  2. Install and run the Red Hat certification pipeline 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.
  5. If you want Red Hat to run all the tests then create a pull request. This triggers the certification hosted pipeline to run all the certification checks on Red Hat infrastructure.

When you complete all the certification checks successfully, you can submit the test results to Red Hat. You can turn on or off this result submission step depending on your individual goals. When the test results are submitted, it triggers the Red Hat infrastructure to automatically merge your pull request and publish your Operator.
