Operating OpenShift

Preface

In late December 2020, a Slack notification from Rick popped up on Manuel’s laptop.

“You know what?” it said, “You and I, we’re going to write a book!”

“What are we going to write about?”

“Operating OpenShift!”

Fast-forward almost two years, and that very book is now before your eyes.

The backstory is that over the past several years, more and more people reached out to us to ask if we would be able to share some of our OpenShift insights with them—​to help them operate their OpenShift clusters more efficiently.

At that time the two of us worked as site reliability engineers for OpenShift clusters at Red Hat. Efficiently operating OpenShift clusters was indeed our day-to-day challenge, and we had accumulated a lot of knowledge and expertise. We used that experience to create this book.

We divided the 10 chapters of this book according to our personal interests and depth of experience. Chapters 1, 3, 5, 8, 9, and 10 are written by Manuel. Chapters 2, 4, 6, and 7 are by Rick.

We learned a lot more about OpenShift in the past two years working on the book. Even with our experience operating OpenShift at Red Hat, many of the tools for operating and automating operations still required further research and experimentation. We’ve done our best to compile the results of our experiments into simple steps that you can follow to get started. Of course, you’ll need to adjust the examples to apply them to your specific needs as soon as you start using the tools.

All the examples use ...
