docker swarm init --advertise-addr $(docker-machine ip node-1)

TOKEN=$(docker swarm join-token -q worker)

for i in 2 3; do
    eval $(docker-machine env node-$i)

    docker swarm join --token $TOKEN --advertise-addr $(docker-machine ip node-$i) $(docker-machine ip node-1):2377
done

eval $(docker-machine env node-1)

docker node ls
