testbed

This page is my personal memo on what I have and how I use the testbed namespace on my homelab.

OS

There are a few OS images doing nothing (tail -f /dev/null).

I use these to test various things, and to validate the commands to run when creating custom container images, Dockerfile.

# enter debian 12 container
kubectl exec deploy/d12 -i --tty -n testbed -- /bin/bash

# reset d12
kubectl delete rs/$(kubectl get rs -n testbed --selector='app=d12' -o jsonpath='{.items[0].metadata.name}') -n testbed

# alpine 3
kubectl exec deploy/a3 -i --tty -n testbed -- /bin/sh

dnsutil

https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/

# lookup "kubernetes.default"
kubectl -n testbed exec -i -t dnsutils -- nslookup kubernetes.default
