Docker.github.io: Networking in Compose - Default driver in swarm mode

[rvernica]

Problem description

The _Networking in Compose_ page mentions that:

The cluster will use the overlay driver by default, but you can specify it explicitly if you prefer - see below for how to do this.

I have a Docker 1.13.0 installation in swarm mode and it seems that bridge is the default network driver. I could not find any reference on the default driver in Docker.

> docker-compose up -d
WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

@rvernica There is info starting here on the default bridge network: https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/

But I'm going to need help on answering this from @dnephin , @shin- , @thaJeztah , @ManoMarks . Can you guys respond?

[dnephin]

That document is referring to https://github.com/docker/swarm, not swarm mode. docker-compose doesn't work directly with Swarm mode (as it says in the warning), you have to go through docker stack deploy.

I'll take a look / claim this :)
