How do I get a list of worker nodes associated to the same master node?

Question

I am looking for a way (Kubernetes API/Command) that returns a list of worker nodes associated to the same master node. I have been digging clues on Google for days but to no avail.

I have tried to look into details of every worker node using "kubectl describe nodes" but none of the options indicate any relationship between the worker node and master node.

I expect something like a list of Worker Node A, Worker Node B and Worker Node C returns when I input the common master node.

In scenario with more than one master, the Kubernetes make leader selection so the other masters stays inactive.

You can use endpoints to check who the master is.

I have managed to get endpoints for pods but not nodes. Is there any other way that can retrieve similar info for nodes? – JH G Jul 15 '19 at 01:16
