Although I've created this Ubuntu server in a variety of ways (WorkSpace, EC2, ...) I always end up in the same place when trying to install rancher-desktop: Nested virtualization not enabled on this host.
Rancher desktop is one way of running kubernetes on your node.If you have docker running on any host, you can use kubernetes-in-docker f.ex to start your kubernetes cluster.https://kind.sigs.k8s.io. Then, after you have KIND running, and you can verify that you can run kubectl get pods or other kubectl commands, you can follow the rest of the documentation to set up your values.yaml and install with helm.
