I am trying to get the name of the master (control-plane) node in my Kubernetes cluster using kubectl. I want the command to return only the name of the node without any additional information.

I have tried the following command:

kubectl get nodes --selector=node-role.kubernetes.io/master

However, this returns a table with additional details. I would like to extract only the node name.

What is the correct kubectl command to achieve this?

With kubernetes-v1.31.0, this works:

kubectl get nodes --selector=node-role.kubernetes.io/master= --output=jsonpath='{.items[0].metadata.name}'
