容器网络命令 ：
docker network --help
常用的是 docker network create/ls/rm/inspect
容器网络类型，一共有以下5种
bridge
–net=bridge
默认网络，Docker启动后创建一个docker0网桥，默认创建的容器也是添加到这个网桥中。
• host
–net=host
容器不会获得一个独立的network namespace，而是与宿主机共用一个。这就意味着容器不会有自己的网卡信息，而是使用宿主
机的。容器除了网络，其他都是隔离的。
• none
–net=none
获取独立的network namespace，但不为容器进行任何网络配置，需要我们手动配置。
• container
–net=container:Name/ID
与指定的容器使用同一个network namespace，具有同样的网络配置信息，两个容器除了网络，其他都还是隔离的。
• 自定义网络
与默认的bridge原理一样，但自定义网络具备内部DNS发现，可以通过容器名或者主机名容器之间网络通信。
下面是对每种网络模式的实战
