Install a docker registry in a k3s kubernetes cluster

k3s doesn't have a builtin plugin for a local registry, so this is how to install the docker registry. The registry will be exposed via the default traefik ingress (on port 80 and 443).

Assumptions

resolvectl query registry.localhost returns 127.0.0.1 - on most Linux distros it does. If not, enable and configure systemd-resolved
K3s comes with traefik ingress controller by default, so the ingress for the registry service is configured for that.
