Question

I've started a docker master with:
docker swarm init --advertise-addr <MANAGER-IP>
so, im trying to have my shell point to swarm master via:
eval $(docker-machine env --swarm <MANAGER-IP>)
but it's giving me an error: Host does not exists

You're mixing up the container based swarm commands with the newer swarmkit based Swarm that's been embedded directly into the Docker CLI. With the new version of Swarm, docker-compose isn't directly supported, yet. Consider this a beta product that works well for a limited scope. You can try the experimental release of the docker engine which adds support for DAB files that are managed with the docker stack CLI. The DAB files are exported from docker-compose bundle and then imported into Docker. This feature is still very experimental and expected to change.
Without that, anything with docker-compose will only operate on a single docker engine since the swarm access is all done under a different docker service CLI interface.
