一、环境准备
centos 安装openvswitch

wget http://openvswitch.org/releases/openvswitch-2.5.4.tar.gz && tar zxvf openvswitch-2.5.4.tar.gz && cd openvswitch-2.5.4 && ./configure && make && make installexport PATH=$PATH:/usr/local/share/openvswitch/scriptsovs-ctl start

测试是否安装成功

# ovs-vsctl show6de04829-aa95-40d7-927f-dc13637133c9    ovs_version: "2.5.4"

centos 安装brctl

yum install -y bridge-utils

创建ovs网桥obr0 并与10.80.86.84建立桥接

export REMOTE_IP=10.80.85.219ovs-vsctl add-br obr0ovs-vsctl add-port obr0 gre0ovs-vsctl set interface gre0 type=gre options:remote_ip=$REMOTE_IP

创建本机docker需要使用的虚拟网桥

brctl addbr br00ifconfig br00 192.168.10.1 netmask 255.255.255.0brctl addif br00 obr0brctl show

docker默认配置文件

ubuntu: vim /etc/default/docker

DOCKER_OPTS="-b=br00"

centos: vim /etc/sysconfig/docker

OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false -b=br00'

主机1,10.80.85.219添加路由

ip route add 192.168.20.0/24 via 10.80.86.84 dev eth0

主机2,10.80.86.84添加路由

ip route add 192.168.10.0/24 via 10.80.85.219 dev eth0

sh config_docker.sh mydocker 4 2 10.80.85.219
