I haven't tried it, but EPMD with DNS discovery should work just fine, and should be similar to this NATS example: https://github.com/psviderski/uncloud-recipes/blob/main/nats...

Basically just configure it with `{service-name}.internal` to find other instances of the service.

I don't know what the specific requirements for the distributed erlang/elixir but I believe the networking should support it. Containers get unique IPs on a WireGuard mesh with direct connectivity and DNS-based service discovery.
