docker 启动具有多个网络接口的容器的方法示例

# docker run --name tst_add_inf -it tst_img /bin/bash

# docker inspect -f '{{.State.Pid}}' tst_add_inf

# ip link add veth0 type veth peer name veth1 

# brctl addif docker0 veth0
# ip link set veth0 up 

# ln -s /proc/$pid/ns/net /var/run/netns/$container_id
# ip link set veth1 netns $pid

# ip netns exec $pid ip link set dev veth1 name eth1
# ip netns exec $pid lp link set eth1 up

$docker create --network=network1 --name container_name containerimage:latest
$docker network connect network2 container_name
$docker start container_name

$docker network create --driver=bridge network1 --subnet=172.19.0.0/24
$docker network create --driver=bridge network2 --subnet=172.19.1.0/24

$docker run --net=host containerimage:latest
