      inspect     Display detailed information on one or more networks
      ls          List networks
      prune       Remove all unused networks
      rm          Remove one or more networks
    
    Run 'docker network COMMAND --help' for more information on a command.

**create：**创建网络

**connect：**将容器连接到网络上

**disconnect：**将容器从网络上断开

**inspect：**查看网络详细信息

**docker network create**

**命令格式：docker network create \[options\] network\_name**

sage:	docker network create [OPTIONS] NETWORK

    Options:
          --attachable           Enable manual container attachment
          --aux-address map      Auxiliary IPv4 or IPv6 addresses used by Network driver (default map[])
          --config-from string   The network from which copying the configuration
          --config-only          Create a configuration only network
      -d, --driver string        Driver to manage the Network (default "bridge")

**示例**

**创建网络：docker network create -d overlay --subnet 10.10.0.0/24 my\_network**

[root@centos docker-swarm]# docker network create -d overlay --subnet 10.10.0.0/24 my_network

**创建服务：docker service create  --network my\_network --replicas 3 --name redis redis**

[root@centos docker-swarm]# docker service create --network my_network --replicas 3 --name redis redis
    py8515pesfqil4nrmgtxka1ab
    overall progress: 3 out of 3 tasks 
    1/3: running   [==================================================>] 
    2/3: running   [==================================================>] 
    3/3: running   [==================================================>] 
    verify: Service converged

**查看服务：docker servce ps redis**

[root@centos docker-swarm]# docker service ps redis
