During the last months, I’ve been working with my colleagues on setting up a workflow that can be used to deploy Spoke clusters in an automated way. More or less, the idea behind this is that a cluster is configured via a set of configuration files and templates so that the required components are installed: Advanced Cluster Management (ACM) Quay registry OpenShift Data Foundation OpenShift Pipelines (a.k.a.

I wanted to write about my experience (before I forget about it), and as some colleagues asked about it… here we go… As published in the blog entry RHEL8 Administration book, some colleagues and I wrote a book on RHEL8 administration, which can be bought here.
