To test the Odigos Operator we wanted to have a realistic OpenShift environment, but even minimal clusters on GKE or EKS were costing us thousands of dollars a month due to OpenShift’s high requirements.

If you like this post, you can learn more about operators from my book, The Kubernetes Operator Framework Book.

As of today, I am officially a published author.

If you are working on changes to a core Kubernetes component such as the scheduler, controller-manager, or apiserver, you may be confused about how to actually build and deploy your changes in a local environment to test them.

I often end up doing test bumps of dependencies that leave my repo with a ton of trash changes that I just want to be able to undo easily and reset my repo including any new or deleted files and directories, so I added this to my .gitconfig : [alias] tra…

Homebrewing is one of my favorite hobbies, so I’m a big fan of Brewer’s Friend for looking up recipes (as well as using their various calculators for OG/FG, IBUs, and others).

Part 1: Introduction to the OpenShift client Part 2: Coding for Kubernetes In the previous post, I went more in-depth into how Kubernetes works in the command line.

Part 1: Introduction to the OpenShift clientPart 3: Writing a controller In my last post, I went over how to set up an OpenShift environment for developing.

Part 2: Coding for KubernetesPart 3: Writing a controller For OpenShift Online, we run several controllers in our cluster which serve functions such as provisioning persistent volumes and providing user analytics.
