2. Configure the Docker container network and host host network in the same network segment using the pipework third-party open Source Network Configuration Tool

#1). Installing the Pipework Open Source Network Configuration Tool

git clone https://github.com/jpetazzo/pipework

CP ~/pipework/pipework/usr/local/bin/

#第2步和第3步和第4步放入脚本一起执行, otherwise there will be a phenomenon of broken network connection

#2). Bind virtual Bridge and physical network card, implement physical network card and virtual network card public IP

Brctl ADDBR Br0

Brctl addif br0 eth0

#3). Configure the physical network card address as the management address of the virtual bridge, because the container does not communicate directly with the physical network card

IP addr del 10.0.0.10/24 dev eth0

Ifconfig br0 10.0.0.10/24 up

#4). Delete the previous route, add a new route, exit to the BR0 virtual network card, gateway to the physical switch

IP route del default

Route add default GW 10.0.0.254

#5). Start a container without a network

Docker run-itd--name Test--net=none Centos/bin/bash

#6). Configure the address and gateway for a container that already exists named Test (if the CENTOS6 upgrade kernel installs Docker This step may be an error, need to upgrade Iproute)
