#StackBounty: #kubernetes Changing Kubernetes cluster IP addres

Bounty: 50

I have a single-node Kubernetes cluster that I need to change IP. I see that the current IP is within many configuration files, which is not a big problem. The bigger problem is that when I changed the address, I had an error that the certificate is valid only for the old IP, not the new one.

How should I perform the change? I assume that I can change the IPs in the config files to a DNS-recognizable hostname, so the configs will be valid for both IPs. Is it possible to regenerate the certificate for a hostname so it will also work regardless of the IP?
