It's not the same. Strangely the docker-swarm tutorial doesn't mention swarm mode. I wasn't able to follow it successfully with Docker 1.12. That was when I realized docker-swarm != swarm mode, so I tried the swarm mode tutorial instead, and it worked as expected.
Maybe docker-swarm is not supported anymore with 1.12? It was all pretty confusing.
