### After server restart (if pods have ImagePullBackOff)
Kind container loses its DNS config on restart:
This should no longer happen — `/etc/docker/daemon.json` is configured with `"dns": ["8.8.8.8"]` to prevent the router's broken IPv6 DNS from being injected into containers. The kind container also has `restart=always` so it auto-starts with Docker.

```bash
docker exec szymicluster-control-plane bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
kubectl delete pods -n argocd --all
kubectl delete pods -A --field-selector=status.phase!=Running 2>/dev/null
