How to add roles to nodes in Kubernetes?
This worked for me:
kubectl label node cb2.4xyz.couchbase.com node-role.kubernetes.io/worker=worker
NAME STATUS ROLES AGE VERSIONcb2.4xyz.couchbase.com Ready custom,worker 35m v1.11.1cb3.5xyz.couchbase.com Ready worker 29m v1.11.1I could not delete/update the old label, but I can live with it.
A node role is just a label with the format node-role.kubernetes.io/<role>
You can add this yourself with kubectl label
Default
Add Role
kubectl label node <node name> node-role.kubernetes.io/<role name>=<key - (any name)>
Remove Role
kubectl label node <node name> node-role.kubernetes.io/<role name>-
