docker 草稿

 1. 从文件系统导入
目前可用的文件系统主要是openvz的模板
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：

sudo docker pull dl.dockerpool.com:5000/ubuntu:14.04
sudo docker tag dl.dockerpool.com:5000/ubuntu:14.04 jw:1
sudo docker run -i -t jw:1 /bin/bash
    
vi /etc/apt/sources.list
dd all
