Introduction After running an OpenShift or Kubernetes cluster for a little while you find that you need to create reports on specific data about the cluster itself. Reporting on things like Project owners, container images in use, and project quota are just some of the things you might be asked about. There are multiple ways to do this, such as writing your own application that queries the API, or creating a shell script that wraps a bunch of cli commands.

Introduction In the last two posts, I have shown you how to get an OKD All-in-One cluster up and running. Since it was an “All-in-One” cluster, there was no redundancy in it, and there was no ability to scale out. OKD and Kubernetes work best in a multi-server deployment, creating redundancy and higher availability along with the ability to scale your applications horizontally on demand. This final blog post is going to outline the steps to build a multi-host cluster.

Intro In my last post, I showed how to deploy an All-in-One OKD system. This is great for some initial learning, but keeping it up and running can get expensive over time. You can always shut it down and re-create it later, but this can take time and you can end up making typos and errors if you aren’t careful. If you want to be able to create (and destroy) these All-in-One environments in a more automatic way read on.
