Hi,

Firstly I would like to say what an awesome project. I have been trying alternatives and looking at this architecture for some time but haven't been successful in creating a reusable deployment of them in such a clean way as you have done here.

I am trying to test this in a swarm. I am happy to help wherever I can with this project as I think this is something that has been sorely missed in the postgres community.

I am trying to set it up in swarm mode just on one machine for the time being. However only the GTM starts if I start it like docker stack deploy --compose-file docker-compose.image.yml postgresxl

My first thought was that the network local might not work in swarm mode so I changed it to overlay in the docker-compose file like this

networks:
  db_a:
    overlay: true
  db_b:
    overlay: true

however it's still not working. I'm happy to dig into it a bit more and perhaps create a separate yml file for swarm if necessary but perhap is there something simple I'm not doing?

Thanks
