当我启动一个新的docker守护程序时，docker目录如下:
/var/lib/docker/
├──aufs
│├──差异
│├──层
│└──mnt
├──容器
├──图
├──初始化
│──└──dockerinit-0.7.3
├──linkgraph.db
├──lxc-start-unconfined->/usr/bin/lxc-start
├──仓库-aufs
└──卷
顾名思义，此结构中每个目录的功能是什么？
最佳答案
我不知道所有文件的确切角色，因此我将从此开始，然后让其他人添加自己的贡献或完善我的文件:
/var/lib/docker/
├── aufs # Storage area for AUFS driver
│ ├── diff # Branch directory of layer
│ ├── layers # Infomation about docker layer
│ └── mnt # Mount point of aufs, root of containers
├── containers # Container configurations
│ (both LXC and Docker-specific)
├── graph # Storage for the images
├── init
│ └── dockerinit-0.7.3 # Used as /sbin/init in containers
├── linkgraph.db # SQLite database storing links
│ and names.
├── lxc-start-unconfined -> /usr/bin/lxc-start # When starting a privileged
│ container, this is used in
│ lieu of lxc-start, to evade
│ AppArmor confinement (which
│ matches by exact path).
├── repositories-aufs # repository infomation
└── volumes # Storage for "anonymous" volumes
(those which are not bind-mounts)
关于docker -/var/lib/docker/中docker目录结构的功能，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/21016210/
