I tried a lot of times to install rancher and always end up to different bugs.
Why not be simple as it says.
My last attempt in the new installation
Failed to create fleet-default/gamkube cluster.x-k8s.io/v1beta1, Kind=Cluster for rke-cluster fleet-default/gamkube: Internal error occurred: failed calling webhook “default.cluster.cluster.x-k8s.io”: failed to call webhook: Post “://webhook-service.cattle-system.svc:443/mutate-cluster-x-k8s-io-v1beta1-cluster?timeout=10s”: service “webhook-service” not found
