How is k0s pronounced?

kay-zero-ess

How do I run a single node cluster?

k0s server --enable-worker

How do I connect to the cluster?

You find the config in ${DATADIR}/pki/admin.conf (default: /var/lib/k0s/pki/admin.conf). Copy this file, and change the localhost entry to the public ip of the controller. Use the modified config to connect with kubectl:

  1. export KUBECONFIG=/path/to/admin.conf
  2. kubectl ...

Why doesn’t kubectl get nodes list the k0s server?

As a default, the control plane does not run kubelet at all, and will not accept any workloads, so the server will not show up on the node list in kubectl. If you want your server to accept workloads and run pods, you do so with: k0s server --enable-worker (recommended only as test/dev/POC environments).
