# 自定义网络

# 创建网络 --subnet 172.168.0.0/16
docker network create --driver bridge --subnet 172.168.0.0/24 --gateway 172.168.0.1 my_bridge_network

# 查看网络详情
docker network inspect my_bridge_network

# 指定网络 启动容器
docker run -itd --name nginx -p 8080:80  nginx

docker run -itd --name nginx1 -p 8081:80 --net my_bridge_network nginx

# 将 nginx 容器 连接到 my_bridge_network 网络中，这样 nginx 和 nginx1 两个容器可以通信了
docker network connect my_bridge_network nginx
