Interesting. Ok, I get a lot of errors, but after running those, it works. 
@dimitarvp I can connect using psql or similar, but I have to check with Docker to see which port the database is running on (because it changes each time I start it).

This makes zero sense, I would recommend to check your setup, this never should happen and it’s not expected behavior, the exposed port is dictated by the configuration and it is never random.

It is random if he didn’t change the ports part of the configuration, the version he linked to was only specifying container port which means that the host port is chosen at random every time.

OK, but should you not specify the host port as well? It’s a trivial change. Doing this dance with the random port is not productive and I don’t understand why you keep sticking to it.

I think this all points to the Broadway example repo benefiting from a pull request that makes this all a bit more straight-forward. As has been suggested here, I think this would make a lot more sense if the ports were fixed.

They likely don’t plan on connecting to the containerized services from the host at all, hence their configuration.
I personally disagree with that choice of theirs but they have a point as well – they have produced something that works and they don’t see why you would need to poke inside it.
In your case however you can change the configuration very easily so I am not sure why do we keep debating the same thing in several different ways.

…btw the README.md also has this in it:
docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management
So even they use the host:container port specification format.

yeah, it’s interesting that they specify the ports in the docker commands, but not in the docker-compose.yml

Again, very likely it’s because their docker-compose.yaml file is used for CI/CD and deployment, not for local development, that’s my hypothesis. If it was used for local dev then surely it would have the host:container port pairs.
