由于GFW的关系，国内用户在使用docker的时候，pull一个基本的镜像都拉下来，更不用说使用官方的index镜像了。差点放弃使用docker了，google了一圈，总算找到办法。
第一步：安装docker
参见官方指南或则各类中文指南
比如下面这两篇：
Docker安装应用(CentOS 6.5_x64)
第二步：从文件系统创建一个image镜像
创建镜像有很多方法，官方的推荐是pull一个，无奈GFW，想下一个基本的Ubuntu都下不下来
还有一个办法就是从一个文件系统import一个镜像，个人推荐可以使用opvz的模板来创建：
openvz的模板下载地址如下：

下载完之后
比如：下载了一个ubuntu14.04的镜像
cat ubuntu-14.04-x86_64-minimal.tar.gz |docker import - ubuntu:14.04
然后用docker images看下：
docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
ubuntu 14.04 05ac7c0b9383 17 seconds ago 215.5 MB
就多了一个我们的ubuntu镜像
第三步：创建私有仓库
官方指南称最简单的办法是 docker run -p 5000:5000 registry，可我们在china
感谢CSDN，我有一个1M的腾讯云服务器，上面搭建了一个私有仓库大家可以使用docker pull 203.195.193.251:5000/registry,到我的服务器下载 速度虽然慢点，但有保证哈
