一、查看Docker IP

root@master:/# ifconfig docker0
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.17.10.1  netmask 255.255.0.0  broadcast 172.17.255.255
        ether 02:42:4e:31:70:a8  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

二、修改IP地址 [切勿与宿主机同网段]

vi /etc/docker/daemon.json

增加以下内容（）

{
     "registry-mirrors": [
         "https://docs.docker.com"
      ],
     "bip": "172.17.10.1/16"
}

三、重启Docker服务

service docker restart

四、查看修改后的Docker IP

root@master:/# ifconfig docker0
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.17.11.1  netmask 255.255.0.0  broadcast 172.17.255.255
        ether 02:42:4e:31:70:a8  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
