出到这节，我在百度搜索了一下“阿里云部署Docker”，突然发现怎么会有人跟我写的一样呢？哦，原来是其它博客系统的爬虫来抓取，然后也不会写转载自什么什么的。所以，我最终明确为什么那些大咖的文章总会在文章的开头写明，转载请注明原创来自xxx的。恩。get it,从这篇開始，我也要这样了。

对阿里云里面部署Docker，我的之前的文章有：
第一篇，安装篇：http://blog.csdn.net/minimicall/article/details/40108305
第二篇，依然是安装：http://blog.csdn.net/minimicall/article/details/40119177
第三篇，基础指令学习：http://blog.csdn.net/minimicall/article/details/40143061
第四篇，容器的使用：http://blog.csdn.net/minimicall/article/details/40144719
今天，我们要进一步解说，
管理本地镜像
创建基础镜像
上传公布镜像
Listing images on the host
我们首先通过 docker images来查看一下我们本地有什么镜像。root@iZ28ikebrg6Z:~# docker images

搜索一个镜像，你能够选择去docker hub的站点搜索，也能够选择在本地用命令行的方式进行。例如以下：

“Official repositories are built and maintained by the Stackbrew project, and Automated repositories are Automated Builds that allow you to validate the source and content of an image.”
选一个pull下来即可了。
Building an image from a Dockerfile
通过Dockerfile来构建一个镜像。用vim写一个Dockerfile，内如例如以下： #This is a comment
FROM ubuntu:14.04
MAINTAINER zengjinlong <470910357@qq.com>
RUN apt-get update && apt-get install -y ruby ruby-dev
RUN gem install sinatra命令都是大写，FROM表示它的源是什么，比如我们这个是给予Ubuntu：14.04的，MAINTANER是维护人员，比方说我，小曾，卖下萌。
RUN表示运行指令。
好，运行上述Dockerfile。
root@iZ28ikebrg6Z:~/docker# docker build -t="zengjinlong/sinatra:v2" .

会耗费比較长的时间。
我们技术下一步的学习。
