Docker Interaction Between Stacks

First create an overlay network:

docker network create -d overlay uber-net

Now deploy two stacks:

docker stack deploy -c docker-compose-1.yml foo
docker stack deploy -c docker-compose-2.yml bar

The configs are included.

Connect to the foo service:

docker exec -it foo_foo.1.xxx sh

Try to ping the bar service from the container:

ping bar

Both bar and bar_bar work for me.
