Recovering an OCP/OKD Cluster After a Long Time Powered Off
Introduction
If you are like me, you have multiple Lab clusters of OpenShift or OKD in your home or work Lab. Each of these clusters takes up a significant amount of resources and so you may shut them down to save power or compute resources. Or perhaps you are running a cluster in one of the many supported Cloud providers, and you power the machines down to save costs when you are not using them. If you leave the cluster powered off for more than 2 weeks you will find that when you power the cluster back on you are unable to connect to the cluster or the console. Most times, this is due to one or more internal certificates expiring. There is a quick fix for this which we will discuss below.
