docker network怎么创建桥接网络

1、简介

docker network来创建一个桥接网络，在docker run的时候将容器指定到新创建的桥接网络中，这样同一桥接网络中的容器就可以通过互相访问。

2、创建网络

docker network create lnmp
1

启动容器时，加入创建的网络

实例一

docker run -it --network lnmp --network-alias mysql  -e MYSQL_ROOT_PASSWORD=123 mysql:5.7
1

实例二

docker run -it --network lnmp --network-alias centos  centos /bin/bash
1

查看所有的docker网络

网络列表

docker network ls
1

网络模式

bridge：桥接docker（默认为桥接模式，自己创建的也是bridge模式）
none：不配置网络，即无
host：和宿主机共享网络
container：容器网络连通（用的少，局限比较大）

检查lnmp网络以查看连接到它的容器

查看网络内部信息

docker network inspect lnmp
1
