This happens only if initialize with kubeadm init -control-plane-endpoint And in the output of journalct -xeu kubelet I get the error: dial tcp: lookup : Temporary failure in name resolution. Following the indications found here: I'm trying to initiate the very first control-plane-node, but I'm getting this error: kubelet is not running or is unhealthy.
