How do you get the Node IP from inside a Pod?

Question

I am running a go app that is creating prometheus metrics that are node specific metrics and I want to be able to add the node IP as a label.

Is there a way to capture the Node IP from within the Pod?

Answer 1

The accepted answer didn't work for me, it seems fieldPath is required now:

  env:
    - name: NODE_IP
      valueFrom:
        fieldRef:
          fieldPath: status.hostIP
