单机让多docker拥有多ip出口

1、创建docker 桥接网络

docker network create \

--driver bridge \

--subnet=172.30.20.0/24 \

--gateway=172.30.20.1 \

nginx-bridge-eth2

2、创建docker-nginx容器

docker run -d --name nginx-eth2-1 \

--network nginx-bridge-eth2 \

nginx

3、添加路由

echo "102 eth2-routing" >> /etc/iproute2/rt_tables

root@hwy-isms-nginx-0-30:/hskj# ip route add default via 192.168.0.1 dev eth2 table eth2-routing

root@hwy-isms-nginx-0-30:/hskj# ip rule add from 172.30.20.0/24 lookup eth2-routing

root@hwy-isms-nginx-0-30:/hskj# ip route flush cache

4、验证

docker exec -it 1676bce8da35 curl cip.cc
