Initialize a swarm
docker@manager:~$ docker swarm init --advertise-addr 192.168.99.100
Swarm initialized: current node (2tjrasfqfu945b7n4753374sw) is now a manager. To add a worker to this swarm, run the following command: docker swarm join \
--token SWMTKN-1-144pfsupfo25h43zzr6b6bghjson8uedxjsndo5vuehqlyarsk-9k4q84axm008whv9zl4a8m8ct \
192.168.99.100:2377 To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
Add a worker node to the swarm
Log into the worker machine.
$ docker-machine ssh worker
