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：
第二篇，依然是安装：
第三篇，基础指令学习：
第四篇，容器的使用：
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 imagesREPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZEubuntu utopic 2185fd50e2ca 2 days ago 237.2 MBubuntu 14.10 2185fd50e2ca 2 days ago 237.2 MBubuntu trusty 9cbaf023786c 2 days ago 192.8 MBubuntu 14.04 9cbaf023786c 2 days ago 192.8 MBubuntu 14.04.1 9cbaf023786c 2 days ago 192.8 MBubuntu latest 9cbaf023786c 2 days ago 192.8 MBubuntu 12.04.5 a9561eb1b190 2 days ago 120.2 MBubuntu precise a9561eb1b190 2 days ago 120.2 MBubuntu 12.04 a9561eb1b190 2 days ago 120.2 MBcentos latest 87e5b6b3ccc1 2 weeks ago 224 MBubuntu 12.10 c5881f11ded9 3 months ago 172.2 MBubuntu quantal c5881f11ded9 3 months ago 172.2 MBubuntu 13.04 463ff6be4238 3 months ago 169.4 MBubuntu raring 463ff6be4238 3 months ago 169.4 MBubuntu saucy 195eb90b5349 3 months ago 184.7 MBubuntu 13.10 195eb90b5349 3 months ago 184.7 MBtraining/webapp latest 31fa814ba25a 4 months ago 278.8 MBubuntu lucid 3db9c44f4520 5 months ago 183 MBubuntu 10.04 3db9c44f4520 5 months ago 183 MB能够看到，我在之前的教程里面拉取了两个一个是ubuntu，一个是training/webapp。当中ubuntu，docker给我拉取了那么多变种回来。上面的输出有一列叫“TAG”，记得我们执行的时候会有"docker run ubuntu:14.04 /bin/bash 么 ！就是依据TAG来精确的指定我们想要执行的那个ubuntu，否则docker会自作聪明的执行TAG为“latest”的那个镜像。
Getting a new image
怎样获取一个新的镜像。我们知道当我们执行一个镜像的时候，假设这个镜像比如centos在本地没有，docker会自己主动的去远端库查询和下载。可是这样的暂时的下载明显是费时间的，我们能够不能够提前去下载呢？能够，使用docker pull拉取指令。root@iZ28ikebrg6Z:~# docker pull centosPulling repository centos^Croot@iZ28ikebrg6Z:~# ^C你看，它会去拉取，只是我中断了，由于我不须要，我的阿里云存储非常金贵的。
Finding 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：
root@iZ28ikebrg6Z:~# docker search redmineNAME DESCRIPTION STARS OFFICIAL AUTOMATEDsameersbn/redmine 40 [OK]webts/redmine Self contained Redmine 2.4 install on Cent... 2 triangle/redmine-plugin-dev Redmine 2.4.1 on ruby 2.0 aimed at plugin ... 1 [OK]oasis/redmine-git 1 melopos/redmine 1 [OK]turnkeylinux/redmine-13.0 TurnKey Redmine - Integrated SCM & Project... 1 sherkenh/redmine 0 oasis/redmine 0 bernigaud/redmine Redmine for my server HAL Forked from same... 0 eprecise/redmine 0 hogefoobar/redmine 0 mattuso/redmine_nginx 0 [OK]mattuso/redmine_mysql 0 [OK]aofox5152/redmine 0 chonglou/redmine remine+mysql+nginx 0 laughk/redmine 0 krickwix/redmine 0 bazitov/redmine 0 sasasin/redmine-scrum ALMinium on CentOS 6, with SSH server. 0 yjkim/apache-redmine 0 sosyco/redmine-sqlite-debian Tryout/GetAndRun Redmine 2.5.1/sqlitel/De... 0 eternnoir/redminebot 0 [OK]sosyco/redmine-mysql-debian Tryout/GetAndRun Redmine 2.5.1/mysql/Debi... 0 hiromiso/redmine2.4 redmine + mysql 0 tmtkd/redminetest Sep. 1st, 2014 test of redmine/docker 0 pvdvreede/redminedev Installation of ruby 2.0.0-p247 and others 0 madmaze/ubunturedmine quick ubuntu 12.04 image with Redmine on s... 0 shaftoe/new_redmine WARNING: old legacy Redmine, not usable fo... 0 mattuso/redmine_unicorn 0 [OK]vpetersson/redmine 0 [OK]miraitechno/redmine 0 [OK]pnelson/redmine 0 [OK]padelt/redmine 0 [OK]binaryphile/redmine Reusable, general-purpose Redmine instance... 0我们搜索了一下redmine，这是个项目管理的服务。上面的列 有，名字，描写叙述，星级（越流行评分越高，提供參考)，是否有官方维护，是否自己主动化，这点我不是非常能理解，我也不敢误人子弟。所以还是引用官网的那句话，各位看官自己理解
“Official repositories are built and maintained by the project, and Automated repositories are 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 commentFROM ubuntu:14.04MAINTAINER zengjinlong <470910357@qq.com>RUN apt-get update && apt-get install -y ruby ruby-devRUN 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" .Sending build context to Docker daemon 2.56 kBSending build context to Docker daemon Step 0 : FROM ubuntu:14.04 ---> 9cbaf023786cStep 1 : MAINTAINER zengjinlong <470910357@qq.com> ---> Running in c5674e71d7e4 ---> 224b40d4b89fRemoving intermediate container c5674e71d7e4Step 2 : RUN apt-get update && apt-get install -y ruby ruby-dev ---> Running in 5d6373cb79e6Ign http://archive.ubuntu.com trusty InReleaseIgn http://archive.ubuntu.com trusty-updates InReleaseIgn http://archive.ubuntu.com trusty-security InReleaseIgn http://archive.ubuntu.com trusty-proposed InReleaseGet:1 http://archive.ubuntu.com trusty Release.gpg [933 B]Get:2 http://archive.ubuntu.com trusty-updates Release.gpg [933 B]Get:3 http://archive.ubuntu.com trusty-security Release.gpg [933 B]Get:4 http://archive.ubuntu.com trusty-proposed Release.gpg [933 B]Get:5 http://archive.ubuntu.com trusty Release [58.5 kB]Get:6 http://archive.ubuntu.com trusty-updates Release [59.7 kB]Get:7 http://archive.ubuntu.com trusty-security Release [59.7 kB]Get:8 http://archive.ubuntu.com trusty-proposed Release [110 kB]Get:9 http://archive.ubuntu.com trusty/main Sources [1335 kB]会耗费比較长的时间。
我们技术下一步的学习。
标记一个image

root@iZ28ikebrg6Z:~/docker# docker tag 224b40d4b89f zengjinlong/sinatra:v3结果显示一下，

删除本地镜像，由于毕竟占地方把。
