示例:
1、manager:
➜ ~ docker swarm init
Swarm initialized: current node (y53c3ts1ycqknb6cfvu56jg2w) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-18kbws8xv6mnfcsvbwo1iwbvdeu139lxbibc8r609t2quwpvtu-e8l9cms7q2rie9uagdvls1eka \
192.168.10.209:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

image nginx:1.11 could not be accessed on a registry to record
its digest. Each node will access nginx:1.11 independently,
possibly leading to different nodes running different
versions of the image.

Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
