docker 数据盘映射方案

docker run -itd -v /data/:/data1 centos  bash // -v 用来指定挂载目录,

:前面的/data为本地目录,:后面的/data1 为容器里的目录:


docker:/root# docker run -itd --name zjtest8_frontend -v /data/zjtest8/frontend/:/var/www 192.168.32.150:5000/zjzc_centos6.5_m3 bash

docker:/root# docker ps

把宿主机的/data/zjtest8/frontend/ 映射到容器的/var/www 目录


bash-4.1# df -h

--privileged=false         Give extended privileges to this container
...
大约在0.6版，privileged被引入docker。
使用该参数，container内的root拥有真正的root权限。
否则，container内的root只是外部的一个普通用户权限。
privileged启动的容器，可以看到很多host上的设备，并且可以执行mount。
甚至允许你在docker容器中启动docker容器。
