前提：

     docker remote api 是docker自带的一个rest api 管理。

     只要在配置文件里面申明下就可以了。


下面是docker remote api的官方的功能目录：

  • Docker Remote API v1.3

    • 3.1 Inside ‘docker run’

    • 3.2 Hijacking

    • 3.3 CORS Requests

    • 2.1 Containers

    • 2.2 Images

    • 2.3 Misc

    • List containers

    • Create a container

    • Inspect a container

    • List processes running inside a container

    • Inspect changes on a container’s filesystem

    • Export a container

    • Start a container

    • Stop a contaier

    • Restart a container

    • Kill a container

    • Attach to a container

    • Wait a container

    • Remove a container

    • List Images

    • Create an image

    • Insert a file in a image

    • Inspect an image

    • Get the history of an image

    • Push an image on the registry

    • Tag an image into a repository

    • Remove an image

    • Search images

    • Build an image from Dockerfile via stdin

    • Check auth configuration

    • Display system-wide information

    • Show the docker version information

    • Create a new image from a container’s changes

    • Monitor Docker’s events

    • 1. Brief introduction

    • 2. Endpoints

    • 3. Going further

创建一个容器 ！


[root@dev-ops ~]$curl -XPOST -H "Content-Type: application/json"  http://127.0.0.1:4243/containers/create -d ‘{ 

     "Hostname":"", 

     "User":"",

     "StdinOnce":false, 

     "Env":null, 

     "Dns":null,

可能会返回的状态 ！

config – the container’s configuration

Status Codes:

201 – no error

404 – no such container

406 – impossible to attach (container not running)

500 – server error


#我们查看下结果

关闭容器，启动容器：

root@dev-ops:~# curl -s -XPOST "http://127.0.0.1:4243/containers/d0274fdba510/stop" 
root@dev-ops:~#

我这边就简单说下，详细的功能实现大家自己翻墙到官网look下吧。 说来也怪，docker时不时的抽风被墙 。我看了国外的论坛，貌似有些公司做了基于docker remote api实现的管理平台。
