SSH to GKE node private IP from the jump server (Bastion host) is not working.
I even tried the following as suggested by one of my friends, but it did not help.
gcloud compute instances add-metadata $INSTANCE_NAME_OR_INSTANCE_ID --metadata block-project-ssh-keys=false --zone $YOUR_VM_ZONE --project $YOUR_PROJECTAlso please confirm if the solution works for Private GKE too.
GKE node is just a GCE VM. You can just access it as a normal GCE instance if with proper privilege and ssh key configured.
One thing worth to mention that GCP support IAP based ssh port forwarding
I have added my ssh keys using gcloud CLI, as in the console the edit option is disabled for all gke nodes.
Now I'm able to do SSH.
