How to find physical interface piped to the pod

kubectl get pods -o wide

Log in to the node:

ssh [node_name]

View the node's virtual network interfaces:

ifconfig

View the containers in the pod:

docker ps

Get the process ID for the container:

docker inspect --format '{{ .State.Pid }}' [container_id]

Use nsenter to run a command in the process's network namespace:

nsenter -t [container_pid] -n ip addr
