I want to get the values of the fields declared in the downwardAPI section of a Pod.

apiVersion: v1
kind: Pod
metadata:
  name: sample
  namespace: default
spec:
  containers:
  - image: rpa
    imagePullPolicy: Always
    name: testbot
    volumeMounts:
    - mountPath: /etc/pod-info
      name: pod-info
  volumes:
  - downwardAPI:
      items:
      - fieldRef:
          apiVersion: v1
          fieldPath: metadata.labels
        path: labels
      - fieldRef:
          apiVersion: v1
          fieldPath: metadata.name
        path: pod-name
      - fieldRef:
          apiVersion: v1
          fieldPath: metadata.namespace
        path: pod-namespace
    name: pod-info

Using client-go, I can use pod.Spec.Volumes[0].DownwardAPI.Items to get the item slice including the fieldPath. But I would now need to dynamically able to fetch whatever values has been declared in the fieldPath. So, from the first item, I would like to access the value of metadata.labels. I could do pod.ObjectMeta.Labels but I would like to access the field dynamically. In terms of Javascript it would have been something like

var foo="metadata.labels"
var fooarr = foo.split(".")
var bar={
  metadata:{
    labels: "foobar"
  }
}
var temp = oof
for(lm of lmaoarr){
  temp = temp[lm]
}
console.log(temp)

How do I do something similar using client-go?
