When you need to set a role for a new node in a Kubernetes cluster, do the following:

Check if the node is correctly added:

kubectl get nodes

Label the new node:

kubectl label node k8w04 node-role.kubernetes.io/worker=worker

Check the nodes again with:

kubectl get nodes

When adding new nodes to the cluster, a token is needed to join the new node to the cluster.

Login into the management node and create a new token:

kubeadm token create --print-join-command

The result is something like this:

kubeadm join 192.168.76.3:6443 --token vcatsw.x589176bunx86udn --discovery-token-ca-cert-hash sha256:35e8c087d7a951747beg3ea5e99c5b1701ac485a019e5474ae1b87c2db52022a
