用swarm manage命令将docker-1节点配置成为管理节点该命令将启用manager服务,且默认监听到2375端口，所有集群的管理都可以通过该服务的接口进行操作，但是manager服务和docker服务
的监听端口相同，而这样做是为了兼容其他基于docker的服务，可以无缝的切换到swarm平台；但有与本次实验采用的是docker容器的方式启用manager服务，本地的2375端口已被docker daemon占用，
所以将manager服务的端口映射到一个空闲的端口12375
root@docker-1:~# docker run -d -p 12375:2375 swarm manage token://1081dc3745b8dfd45ff863c13d74d96c

tcp6 0 0 :::12375 :::* LISTEN 2191/docker-proxy

产看docker-1节点运行的容器和所有容器
