pipework的安装
wget https://github.com/jpetazzo/pipework/archive/master.zip unzip master.zip
cp pipework-master/pipework  /usr/local/bin/
chmod +x /usr/local/bin/pipework

这里最好不要让docker自动获取ip，下次启动会有变化而且自动获取的ip可能会和物理网段中的ip冲突
docker run -itd --net=none --name=test centos7 /bin/bash
为test容器设置一个与桥接物理网络同地址段的ip@网关
pipework br0 test 192.168.56.11/24@192.168.56.2
