[root@master ~]# docker swarm init --advertise-addr 172.16.60.95
Swarm initialized: current node (kfi2r4dw6895z5yvhlbyzfck6) is now a manager.
 
To add a worker to this swarm, run the following command:
 
    docker swarm join --token SWMTKN-1-3fzyAz5knfbhw9iqlzxhb6dmzdtr0izno9nr7iqc5wid09uglh8-0mocmawzvm3xge6s37n5a48fw 172.16.60.95:2377
 
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

[root@master ~]# docker node --help

Usage:    docker node COMMAND

Manage Swarm nodes

Options:


Commands:
  demote      Demote one or more nodes from manager in the swarm
  inspect     Display detailed information on one or more nodes
  ls          List nodes in the swarm
  promote     Promote one or more nodes to manager in the swarm
  ps          List tasks running on one or more nodes, defaults to current node
  rm          Remove one or more nodes from the swarm
  update      Update a node


# demote
   将管理节点降级为普通节点
# inspect
    查看节点的详细信息
# ls
   列出节点
# promote
   将普通节点升级为管理节点
# ps
   查看运行的任务
# rm
   从swarm集群中删除节点
# update
   改变集群节点状态
[root@master ~]# docker node update --help

Usage:    docker node update [OPTIONS] NODE

Update a node

Options:
      --availability string   Availability of the node ("active"|"pause"|"drain")
      --label-add list        Add or update a node label (key=value)
      --label-rm list         Remove a node label if exists
      --role string           Role of the node ("worker"|"manager")


# 主要使用availability string

# active
    节点状态正常
# pause
    节点挂起、暂停
# drain
    排除节点，比如将master节点排除，不分配任务，只作为管理节点
