系统[debian 6.0.6 wheely 64bit]安装docker 1.2.0
1.安装docker
echo deb http://get.docker.io/ubuntu docker main | sudo tee /etc/apt/sources.list.d/docker.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
sudo apt-get update
sudo apt-get install -y lxc-docker
2.新建虚拟机（容器）
1.搜索虚拟机，这是从docker hub中搜的
命令如下：
docker search [虚拟机名称]
如搜索debian系统的虚拟机：
docker search debian|less
注意：此search命令显示的时候，没有tags标记，如果仓库中有好几个版本，不带tags下载，是把所有版本的都下载。最好通过docker官网搜索仓库（官网地址：https://registry.hub.docker.com/）可看tags标记（版本号），再下载。
如下载docker开发环境1.2.0，使用命令为：
docker pull docker-dev:1.2.0
2.下载一个debian虚拟机
我下载的是kelseyhightower/debian虚拟机
docker pull kelseyhightower/debian
如出现如下错误：
http:///var/run/docker.sock/v1.14/images/json: dial unix /var/run/docker.sock: no such file or directory
表示docker服务没有启动，请运行
/etc/init.d/docker start
启动docker服务
此时可以看到从亚马逊的服务器上下载kelseyhightower/debian镜像
具体地址如下(有可能你下载的时候，服务器有所变化)：
域名：server-54-230-149-71.sin2.r.cloudfront+.net:https
IP:54.230.149.71:443
注意:它们之间的通信为json格式，下面是例子，字段名称一目了然

7.驱动配置目录
1.驱动配置目录在/var/lib/docker/execdriver/native/[ID]下,这个目录如果驱动变换，它也变化
2.文件包括：

3.在虚拟机中安装VIM
两种方法：
1.进入到虚拟机中与正常机子安装一样
2.用docker安装
命令如下：
docker run [ID] apt-get install -y vim
4.提交更改到镜像中
使用命令如下：
docker commit [ID] [注释信息]
如：
docker commit 633710bf0be63 'install/vim'
