title: Add iptable rules by a pod inside itself and also in the worker node
body: <p>I have a requirement where I'll deploy a pod and when it comes up I need to add some iptable rules inside the pod.
  At the same time, I need to add some iptable rules in the worker node on which the pod is running.</p>
  <p>If I use &quot;hostNetwork&quot; option for the pod, the iptable rules which I need to add in the pod will also get added to the worker node.</p>
  <p>How can this be achieved, where the pod itself adds iptable rules inside the pod as well as in the worker node.</p>
