Hello !
I also try to do that, it will be very much secure to have a whole Kubernetes cluster inside a private Network, and just access to apps, throught Floating IP / Load Balancer (we just installed Octavia in our OpenStack cluster to have it used by the Ingress Controler).
I already have deployed a K8s cluster throught rke CLI, with bastion parameters. I worked. But I would like to have Rancher managing the machines (create instances, re-create if failed…).
When I copy/paste the bastion section in the cluster config in the Rancher Web UI, the ssh_key element is removed…
I don’t konw if it the only reason why it doesn’t work, but that’s all I can see.
Does someone knows if there are logs somwhere ? The Provisoning Logs tab is empty in the Web UI.
there’s a more recent thread here : "Waiting for SSH to be available" message
