Is there anyway to obtain the node information that the pod is working on?

[zouyonghe]

I am looking for someway to get the label of the node which the pod is working on.
I got the podlist by specific the namespace and the K&V label firstly. Then I should get the instanceId of the node which the pod in podlist is working on it. The instanceId is a K&V label of the node.
I hava no idea using the api dealing with the second step.It will be lots of thanks if you help me.

Could you please elaborate your question? What do you mean instanceId? Do you mean node name? You should be able to get Node name from pod.getSpec().getNodeName()
