Chapter 18. Working with Operators


Certify your operator image or necessary container image as a component 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 Operator Lifecycle Manager (OLM) on the OpenShift platform and is formatted properly, using Red Hat certified container images.

18.2. Certification workflow for Operators


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-

18.2.1. Certification on-boarding for Operators

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.

18.2.2. Certification testing for Operators

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.

It is possible that some operator releases seemingly disappear from the catalog, which happens when the graph gets automatically pruned, resulting in some operator versions being excluded from the update graph. Because of that, you will get blocked from releasing an operator bundle when it results in a channel with fewer or equal release versions than the one before.

In the case that you want to prune the graph intentionally, you can do so by skipping a test and restarting the pipeline using the following available commands in your pull request:

/test skip <test_case_name>

test_case_name test will be skipped. Note that only a subset of tests can be skipped.

/pipeline restart certified-hosted-pipeline

The hosted pipeline will re-trigger.

18.2.3. Publishing the certified Operator on the Red Hat Ecosystem Catalog

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.
