kube-system pod/calico-node-9czgm 0/1 Running 3 42d
kube-system pod/calico-node-msfjk 0/1 Running 0 5m37s
...is what I get when a let "moon" to join the cluster as outlined below...
NAMESPACE NAME STATUS ROLES AGE VERSION
node/moon Ready <none> 5m38s v1.20.5
node/sky Ready control-plane,master 276d v1.21.2
Whereby pod/calico-node-9czgm is sky's calico node that is running just fine (1/1 Ready) before moon joins and after moon is deleted from the k8s cluster.

The IP 192.168.178.23 belongs to my notebook's WiFi interface. So apparently I need to override the local' interface IP with my public IP which I try to do via --node-ip=93.93.17.11 in /etc/systemd/system/kubelet.service.d/kubeadm.conf but everything remains broken and the kubelet additionally reports:
Jul 04 22:58:43 moon kubelet[92613]: E0704 22:58:43.610441 92613 kubelet_node_status.go:586] Failed to set some node status fields: failed to validate nodeIP: node IP: "93.93.17.11" not found in the host's network interfaces
I am using K8s v1.20.5 with cri-o v1.20 on Fedora 34.
