How to add roles to nodes in Kubernetes?

Question

When I provision a Kubernetes cluster using kubeadm, I get my nodes tagged as "none". It's a known bug in Kubernetes and currently a PR is in progress.

However, I would like to know if there is an option to add a Role name manually for the node.

root@ip-172-31-14-133:~# kubectl get nodes NAME               STATUS    ROLES     AGE       VERSION ip-172-31-14-133   Ready     master    19m       v1.9.3 ip-172-31-6-147    Ready     <none>    16m       v1.9.3

This worked for me:

kubectl label node cb2.4xyz.couchbase.com node-role.kubernetes.io/worker=worker

NAME                                          STATUS    ROLES           AGE       VERSION cb2.4xyz.couchbase.com                          Ready     custom,worker   35m       v1.11.1 cb3.5xyz.couchbase.com                          Ready     worker          29m       v1.11.1 

I could not delete/update the old label, but I can live with it.
