Just two pods for testing
If you want to test out some kubernetes settings like DNS, this addon is very handy. Starts up two containers, resin/rpi-raspbian and luxas/alpine. They both sleep for one hour and then restarts forever.
Example use:
kubectl exec -it alpine-sleep /bin/sh
kubectl exec -it raspbian-sleep /bin/bash
kubectl exec -it alpine-sleep -- nslookup kubernetes.default.svc.cluster.local
