Has anyone ever attempted to change the hostname of their cluster servers? I had built a cluster for an environment and we decided to change the name of the env and therefore I wanted to update the cluster servers hostnames to reflect this. After updating the hostname on one of the master nodes and restarted k3s, the k3s server is failing to start. I was hoping to make this change without affecting the workloads on the cluster.

no, you basically need to delete the nodes from the cluster and rejoin them with the new name.

And that is exactly what I did. Just finished too. But hey, thanks again for your input.
