I think the solution might require CLI to discover that cilium is being deployed to openshift

rolinh commented 2 years ago

The cluster name is invalid because it ends with :6443, which is invalid for a DNS sub-domain (see RFC1123). Try removing the port section from your domain name.

alexander-demicev commented 2 years ago

Never mind my previous comment, looks like the cluster name is being discovered from the current context of the kubeconfig.

contexts:
- context:
    cluster: mycluster
    user: myuser
  name: myuser
current-context: myuser

Issue might be resolved by checking that the cluster name contains a valid name in both contexts and clusters section of the kubeconfig.
