Network

查看網(wǎng)絡(luò)，容器的默認網(wǎng)絡(luò)為bridge：

docker network ls

NETWORK ID          NAME                DRIVER              SCOPE
683676f81e6d        bridge              bridge              local               
7dbfac5ee958        harbor_harbor       bridge              local               
bf582c40ad25        host                host                local               
c4e4ab511320        none                null                local

inspect網(wǎng)絡(luò)可以查看關(guān)聯(lián)到該網(wǎng)絡(luò)的容器:

docker network inspect harbor_harbor

另一種查看的方式

docker inspect --format='{{json .NetworkSettings.Networks}}'  db

剔除網(wǎng)絡(luò)中的一個容器：

docker network disconnect harbor_harbor nginx

創(chuàng)建自己的網(wǎng)絡(luò):

docker network create -d bridge my_bridge

在run的時候指定網(wǎng)絡(luò)：

docker run -d --net=my_bridge --name db training/postgres

連接已經(jīng)存在的容器：

docker network connect my_bridge web

在同一網(wǎng)絡(luò)中允許直接將容器的名稱作為host名稱报腔。
