用户自定义bridge****

1. 在主机上通过命令docker network ls可以查看docker中存在的网络：

	docker network ls
	# 输出结果：
NETWORK ID          NAME                DRIVER              SCOPE
e79b7548b225        bridge              bridge              local
666d5f1f459d        host                host                local
d0d785cf4794        none                null                local

POWERSHELL

1. 创建用户自定义bridge：

docker network create my-net        # 创建了一个名为"my-net"的网络
BASH

1. 将Web服务容器和mysql服务容器加入到”my-net”中，并观察变化：

docker network connect my-net test_demo         # 将Web服务加入my-net网络中
docker network connect my-net mysqld5.7         # 将mysql服务加入my-net网络中
BASH

1. 查看my-net的网络配置

# 查看my-net的网络配置
docker network inspect my-net
# 输出结果（省略部分内容）：
