Docker官方为了让用户快速了解Docker，提供了一个交互式教程，旨在帮助用户掌握Docker命令行的使用方法。

Docker 命令行

下面对Docker的命令清单进行简单的介绍，详细内容在后续章节详细介绍。可以通过运行 docker ，或者 docker help 命令得到命令行的帮助信息（我们还是以 vmware 上的 coreos 为操作环境，如无特殊说明后文都采用这个环境）:

core@localhost ~ $ docker
Usage: docker [OPTIONS] COMMAND [arg...]
 -H=[unix:///var/run/docker.sock]: tcp://host:port to bind/connect to or unix://path/to/socket to use

A self-sufficient runtime for linux containers.

Commands:
    attach    Attach to a running container
    build     Build an image from a Dockerfile
    commit    Create a new image from a container‘s changes
    cp        Copy files/folders from a container‘s filesystem to the host path
    diff      Inspect changes on a container‘s filesystem
    events    Get real time events from the server
    export    Stream the contents of a container as a tar archive
    history   Show the history of an image
    images    List images
    import    Create a new filesystem image from the contents of a tarball
    info      Display system-wide information
    inspect   Return low-level information on a container
    kill      Kill a running container
    load      Load an image from a tar archive

    logout    Log out from a Docker registry server
    logs      Fetch the logs of a container
    port      Lookup the public-facing port that is NAT-ed to PRIVATE_PORT
    pause     Pause all processes within a container
    ps        List containers
    pull      Pull an image or a repository from a Docker registry server
    push      Push an image or a repository to a Docker registry server
    restart   Restart a running container
    rm        Remove one or more containers
    rmi       Remove one or more images
    run       Run a command in a new container
    save      Save an image to a tar archive
    search    Search for an image on the Docker Hub
    start     Start a stopped container
    stop      Stop a running container
    tag       Tag an image into a repository
    top       Lookup the running processes of a container
    unpause   Unpause a paused container
    version   Show the Docker version information
    wait      Block until a container stops, then print its exit code

• 其中 info、version是系统环境信息相关的命令
• events、history、logs 是日志信息相关的命令
• login\pull\push\search是ＤockerＨub服务相关的命令
• 其余都是日常维护相关的命令

命令语法

基本用法：命令+参数

core@localhost ~ $ docker info
Containers: 7
Images: 123
Storage Driver: btrfs
Execution Driver: native-0.2
Kernel Version: 3.16.2+
Operating System: CoreOS 444.0.0
core@localhost ~ $ docker version
Client version: 1.2.0
Client API version: 1.14
Go version (client): go1.3.1
Git commit (client): fa7b24f
OS/Arch (client): linux/amd64
Server version: 1.2.0
Server API version: 1.14
Go version (server): go1.3.1
Git commit (server): fa7b24f

单个字符的参数可以放在一起：

core@localhost ~ $ docker run -t -i ubuntu:14.04 /bin/bash
#使用分开的参数
root@d512e393fc74:/# exit
exit
core@localhost ~ $ docker run -ti ubuntu:14.04 /bin/bash
#将当个支付的参数放在一起
root@d170dacef325:/# exit
exit
core@localhost ~ $ docker rm d51 d17
#多个参数放在一行
d51
d17
core@localhost ~ $

Ｄocker 后台进程参数

Docker 配置文件位置

Ｄocker 的配置文件可以设置大部分的后台进程参数，在各个操作系统中的存放位置不一致

在 ubuntu 中的位置是：/etc/default/docker

在 centos 中的位置是：/etc/sysconfig/docker
