Forgot to add .local I see

I hope Orbstack is also advertising those hostnames on mDNS, because using .local (or, seemingly worse, _relying_ on .local) will conflict with resolver logic on all kinds of devices.

I'm not seeing any broadcasts.

What it does is it has a private network for the containers and itself (all containers get their own unique IP, so there's no port mapping needed).

http://orb.local simply lists all running containers.

The host-names are automatically derived from the containername / directoryname / compose project, but you can add other hostnames as well by adding docker labels.

It works really well.

It was an example how OrbStack puts together the domain.
