How to add roles to nodes in Kubernetes?


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

Solution

  • 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.
