关于docker rest api接口组件docker remote api的使用

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 p_w_picpath

Insert a file in a p_w_picpath

Inspect an p_w_picpath

Get the history of an p_w_picpath

Push an p_w_picpath on the registry

Tag an p_w_picpath into a repository

Remove an p_w_picpath

Search p_w_picpaths

Build an p_w_picpath from Dockerfile via stdin

Check auth configuration

Display system-wide information

Show the docker version information

Create a new p_w_picpath from a container’s changes

Monitor Docker’s events

1. Brief introduction

2. Endpoints

3. Going further

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。
