Sniff hostnetwork traffic from a kubernetes pod
Question
I have a pod running in a production cluster. The pod is for debugging purpose and I would like to sniff the host network traffic. For security reason, I cannot deploy the pod in the host network.
Is it possible to sniff the host network traffic from a non hostnetwork pod in kubernetes?

A Pod only received traffic that is addressed to the Pod.
A CNI plugin is the component that you would be interested in, since that a way to plugin and intercept the traffic.
