1、swarm-master 创建集群 1.1 切换切换活跃主机  test@bogon:~$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS 73 * generic Running tcp://192.168.1.73:2376 v17.06.0-ce 80 - generic Running tcp://192.168.1.80:2376 v17.06.0-ce test@bogon:~$ docker-machine active 73 test@bogon:~$ eval $(docker-machine env 80) test@bogon:~$ docker-machine active 80 1.2创建swarn镜像 test@bogon:~$ docker run swarm create Unable to find image 'swarm:latest' locally latest: Pulling from library/swarm 248cc99c8148: Pull complete 0aeceddbda61: Pull complete c90a34ed5817: Pull complete Digest: sha256:02040b8e8292aacb6e30be8babd613f1c253a3ec665d2fbc178d1745810fdd29 Status: Downloaded newer image for swarm:latest Token based discovery is now deprecated and might be removed in the future. It will be replaced by a default discovery backed by Docker Swarm Mode. Other mechanisms such as consul and etcd will continue to work as expected. 3e2a3fa482c1994ad5ee684f120e27c4 #最后一行为CLUSTER_ID一定保留下好，下面增加节点都会用到 1.3增加主控节点swarm-master

2管理swarm 2.1退出集群 test@bogon:~$ docker swarm leave --force Node left the swarm. #使用docker-machine切换环境分别在swarm-node1，swarn-master退出集群，以下仅涉及到切换环境不提供代码参见1.1 2.2 swarm-master建立集群 test@bogon:~$ docker swarm init
Swarm initialized: current node (69nkaqu3ivfmty5isz0ug0oiw) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-1qj2mfe14jw2tzhg1fxpqiyhxpnm4bqhrhae0dtpp6ip9og4s3-btyj7t5304eyeuhrl4dw1vx1l 192.168.1.80:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
#同样token很重要，不要丢失，docker代码提示很明白，加入集群命令摆在那里 2.3 swarm-node1 加入集群  test@bogon:~$ docker swarm join --token SWMTKN-1-1qj2mfe14jw2tzhg1fxpqiyhxpnm4bqhrhae0dtpp6ip9og4s3-btyj7t5304eyeuhrl4dw1vx1l 192.168.1.80:2377 This node joined a swarm as a worker. test@bogon:~$ eval $(docker-machine env swarm-master) test@bogon:~$ docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 0jmswkqce9cqjvri9awdm37ty swarm-node1 Ready Active 69nkaqu3ivfmty5isz0ug0oiw * swarm-master Ready Active Leader 3 删除节点 3.1管理节点删除 test@swarm-master:~$ docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 0jmswkqce9cqjvri9awdm37ty swarm-node1 Ready Active 69nkaqu3ivfmty5isz0ug0oiw * swarm-master Ready Active Leader 3.2 删除普通节点 test@swarm-node1:~$ docker swarm leave --force Node left the swarm.
