I was getting more at stacks on a host talking, ie: you have a postgres stack with PG and Pgadmin, but want to use it with other stacks or k8s swarm, without exposing the pg port outside the machine.

You can do that by joining the containers to the same docker network, you don’t need to expose ports even to localhost.

I mustn’t be communicating well, but that’s fine.
