show which veth interface is associated with each container

Find veth interface of docker containers

This repository contains a script for finding the veth interfaces of every container. For example you might see a lot of veth interfaces on a K8s node/ docker host, but you can't figure out which namespace or container the veth interface is associated with. This info can be helpful while debugging. The script docker-veth.sh can be run from a privileged container on the same node.

Usage on K8s

Run a privileged pod using the samos123/docker-toolbox image that already contains this script and other useful troubleshooting tools.

kubectl apply -f debug-pod.yaml
kubectl exec debug-pod -t -i bash
docker-veth.sh
