WARNING: No swap limit support

Anything else?

I am connected to a remote host.

Now if this is not supported in stack deploy that would clear things up, but if that's the case it should print such an error.
Additionally some documentation should be added, because I cannot seem to find anything about it...

Anyway, hope to hear from others :)

Following as long syntax looks like not implemented for stack deploy.

Swarm does not currently support the newer Compose Spec. Swarm is on the older 3.9 specification, which doesn't implement depends_on for Swarm. See the note in docs: https://docs.docker.com/compose/compose-file/compose-file-v3/#depends_on

Please report swarm-related issues to docker/cli, this repository is for docker compose project.
