Default Network

Docker installation is done by default create 3 network, can listen to song Docker network LS (version in 1.9 and above) command view.

$ docker Network LS
network ID          NAME                DRIVER
7fca4eb8c647
Bridge 9f904ee27bf5        none                null
CF03EE007FB4        host                Host

Bridge is the default container network in the system only for DOCKER0 (which can be viewed via ifconfig or IP addr), the default boot container is connected to the DOCKER0, you can restart the container is through the –net parameter Docker run--net =<network> Specifies that the container is connected to the network.

None means that the container does not have network functionality, and when you connect to the container (example: Docker exec-it Container_name/bin/bash) You cannot see the other network adapters through Ifconfig or IP addr. Only the local loopback network.

host when using the hosts network, container will use the mainframe's network stack.

View network details Docker network inspect bridge, you can view all the network details listed in LS by inspect.

$ docker Network inspect bridge
[
   {
       ' Name ': ' Bridge ',
       ' Id ': ' f7ab26d71dbd6f557852c7156ae0574bbf62c42f539b50c8ebde0f728a253b6f ","
       Scope ":" Local ",
       " Driver ":" Bridge ",
       "IPAM": {"
           Driver": "Default",
           "Config": [
               {
                   "Subnet": "172.17.0.1/16",
                   "Gateway": " 172.17.0.1 "
               }
           ]
       },
       " containers ": {},
       " Options ": {
           " Com.docker.network.bridge.default_bridge ": True",
           "COM.DOCKER.NETWORK.BRIDGE.ENABLE_ICC": "True",
           " Com.docker.network.bridge.enable_ip_masquerade ": True",
           "Com.docker.network.bridge.host_binding_ipv4": " 0.0.0.0 ",
           " Com.docker.network.bridge.name ":" Docker0 ",
           " COM.DOCKER.NETWORK.DRIVER.MTU ":" 9001 "
       }
   }
]
This is not a detailed description of all the parameters, the basic view can be understood in the ' container ' parameter content is the container information belonging to this network.

Custom Network

Creating a custom network is simple Docker network create--driver Bridge Mnet, create a bridge network called Mnet,

$ docker Network Inspect Mnet
[
    {
        ' Name ': ' Mnet ',
        ' Id ': ' 50650309e0813bdad175b6c486168a3cdbcdc171adde3b21428c262943f5221b ","
        Scope ":" Local ",
        " Driver ":" Bridge ",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "Default",
            "Options": {},
            "Config": [
                {
                    ] Subnet ":" 172.18.0.0/16 ","
                    Gateway ":" 172.18.0.1/16 "
                }
            ]
        },
        " Internal ": false,
        " Containers ": {}, '
        options ': {},
        ' Labels ': {}
    }
]

Note The custom network does not support link. Multi-Host network

Docker multiple host networks rely on distributed storage systems and Docker LIBKV libraries. Not in the back.
