One of our customers is in the process of decommisioning their OpenShift v3.11 cluster. This cluster is currently still used for building customer specific base images. Over time quite a few elaborated pipeline builds (based on Jenkins) have been developed for that purpose.
The customer wanted me to migrate the existing pipeline builds on their v3.11 cluster to Tekton (aka OpenShift Pipeline) builds running on their new v4.9 cluster. This task turned out to be quite pesky. Tekton is a beast in many aspects.

In this article, I will show you how to install Red Hat OpenShift Container Platform 4.3 (OCP) on VMware vSphere with static IPs addresses using the openshift installer in UPI mode and terraform. In contrast to the official OpenShift 4.3 install documentation, we will not use DHCP for the nodes and will not setup the nodes manually - instead we will use static IP addresses and terraform to setup the virtual machines in our vCenter.
