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.

Intro The other day I was reading an article on OpenShift All-in-One and thought it would be interesting to re-create it with OKD, the community version of OpenShift. We are going to create an All-In-One (AiO) version of version 3.11 of OKD/OpenShift on Azure. This post is going to show you how to do an manual install of OKD on just one host. Why would you want to do this? This will get you a fully working instance of OpenShift and even give you cluster admin rights so you can learn how to administer it.
