Indeed! I use Headscale (though hosted Tailscale will work just fine), DO hosts the controlplane, and is also on the tailnet itself. My Caddy config has something like:

  <list of public hosts> {
    reverse_proxy 100.64.0.<mini PC>
  }

The mini PC IP is a Tailscale container in a pod with a second Caddy instance that routes within the cluster. For sensitive/personal services, they're only configured in the cluster-internal Caddy config, and thus only accessible over the tailnet.

One can optionally add other "hardening" at the DO layer, like Crowdsec, to minimize automated/malicious/bot traffic into your home.
