I use gluetun, my arr stack and bittorrent client in a single docker-compose. I use the syntax

    depends_on:
      gluetun:
        condition: service_healthy

in the stack to make sure that the bittorrent client doesn’t try to connect too early. All that works great.

I also use that same VPN connection for other containers too (not in the same docker-compose stack). I do that by simply using network_mode: "container:gluetun" in the second yaml file. But I’d like to use the same depends_on syntax. But it errors out because gluetun is undefined in the second stack.

So my question is, how do I make sure the containers in docker compose stack 2 start after docker compose stack 1 (the one with gluetun) is healthy?
