I have a pod with the following specs

kind: Pod
metadata:
  name: busybox
  namespace: default
spec:
  containers:
  - image: busybox
    command:
      - sleep
      - "3600"
    imagePullPolicy: IfNotPresent
    name: busybox
    env:
      - name: WATCH_NAMESPACE
        valueFrom:
          configMapKeyRef:
            name: watch-namespace-config
            key: WATCH_NAMESPACE
  restartPolicy: Always

I also created a ConfigMap

kubectl create configmap watch-namespace-config \
        --from-literal=WATCH_NAMESPACE=dev

The pod looks for values in the watch-namespace-config configmap.
When I manually change the configmap values, I want the pod to restart automatically to reflect this change. Checking if that is possible in any way.
