/ var / lib / docker /中docker目录结构的功能

当我启动一个新的docker守护进程时，docker目录是这样的：

/var/lib/docker/
├── aufs
│   ├── diff
│   ├── layers
│   └── mnt
├── containers
├── graph
├── init
│   └── dockerinit-0.7.3
├── linkgraph.db
├── lxc-start-unconfined -> /usr/bin/lxc-start
├── repositories-aufs
└── volumes

正如 Headers 所说，这个结构中每个目录的功能是什么？

    我不知道所有文件的确切作用，所以我将从这开始，让其他人添加他们自己的贡献，或者改进我的：

    /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)
