容器網絡命令 ：
docker network --help
常用的是 docker network create/ls/rm/inspect
容器網絡類型，一共有以下5種
bridge
–net=bridge
默認網絡，Docker啟動后創建一個docker0網橋，默認創建的容器也是添加到這個網橋中。
• host
–net=host
容器不會獲得一個獨立的network namespace，而是與宿主機共用一個。這就意味着容器不會有自己的網卡信息，而是使用宿主
機的。容器除了網絡，其他都是隔離的。
• none
–net=none
獲取獨立的network namespace，但不為容器進行任何網絡配置，需要我們手動配置。
• container
–net=container:Name/ID
與指定的容器使用同一個network namespace，具有同樣的網絡配置信息，兩個容器除了網絡，其他都還是隔離的。
• 自定義網絡
與默認的bridge原理一樣，但自定義網絡具備內部DNS發現，可以通過容器名或者主機名容器之間網絡通信。
下面是對每種網絡模式的實戰
