03/14/2023, 9:59 AMHi All, I'm attempting to set up an on-premises K8S cluster with Rancher on Vsphere. I'm using a Docker container to access the Rancher Management UI, and my concern is how I'll access the configured management UI again if the Docker container dies for any reason. Do you also recommend this method for production workloads?

Also, the only purpose I am using Rancher for is to create an on-prem K8S cluster on Vsphere. I don't have any existing HA K8S cluster there to host Rancher itself, that's why the first choice was Docker on a single node. Any alternative way you recommend for this use-case to set up an on-prem cluster on Vsphere? @agreeable-oil-87482

03/14/2023, 5:07 PMThanks for the prompt response David, but if the k3s VM itself fails, Will it impact the configured Vsphere K8S cluster and deployments on it? Also, how to access the management UI again in such a case, any fallback approach?
