title: How to find control plane IP addresses for a regional GKE cluster
body: <p>I mistakenly deleted the firewall entry that allows the control plane nodes to establish <a href="https://stackoverflow.com/questions/36375030/kubectl-error-from-server-no-ssh-tunnels-currently-open">ssh tunnels</a> to the worker nodes. I need to recreate the firewall entry, but I can't find the IP addresses of the controller nodes.</p>
  <p>This is a regional cluster, so the cluster endpoint is a load balancer that sits in front of the 3 control plane IPs. I don't see that load balancer in my GCP console though, so I can't get its details.</p>
  <p>How do I find the IP addresses of the 3 control plane nodes in a GKE regional cluster?</p>
