阿里云部署Docker(5)----管理和发布您的镜像，阿里docker
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，原来是其他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，我终于明白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,从这篇开始，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，依旧是安装：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，我们要进一步讲解，
管理本地镜像
创建基础镜像
上传发布镜像
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 REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE ubuntu utopic 2185fd50e2ca 2 days ago 237.2 MB ubuntu 14.10 2185fd50e2ca 2 days ago 237.2 MB ubuntu trusty 9cbaf023786c 2 days ago 192.8 MB ubuntu 14.04 9cbaf023786c 2 days ago 192.8 MB ubuntu 14.04.1 9cbaf023786c 2 days ago 192.8 MB ubuntu latest 9cbaf023786c 2 days ago 192.8 MB ubuntu 12.04.5 a9561eb1b190 2 days ago 120.2 MB ubuntu precise a9561eb1b190 2 days ago 120.2 MB ubuntu 12.04 a9561eb1b190 2 days ago 120.2 MB centos latest 87e5b6b3ccc1 2 weeks ago 224 MB ubuntu 12.10 c5881f11ded9 3 months ago 172.2 MB ubuntu quantal c5881f11ded9 3 months ago 172.2 MB ubuntu 13.04 463ff6be4238 3 months ago 169.4 MB ubuntu raring 463ff6be4238 3 months ago 169.4 MB ubuntu saucy 195eb90b5349 3 months ago 184.7 MB ubuntu 13.10 195eb90b5349 3 months ago 184.7 MB training/webapp latest 31fa814ba25a 4 months ago 278.8 MB ubuntu lucid 3db9c44f4520 5 months ago 183 MB ubuntu 10.04 3db9c44f4520 5 months ago 183 MB可以看到，我在之前的教程里面拉取了两个一个是ubuntu，一个是training/webapp。其中ubuntu，docker给我拉取了那么多变种回来。上面的输出有一列叫“TAG”，记得我们运行的时候会有"docker run ubuntu:14.04 /bin/bash 么 ！就是根据TAG来精确的指定我们想要执行的那个ubuntu，否则docker会自作聪明的运行TAG为“latest”的那个镜像。
Getting a new image
root@iZ28ikebrg6Z:~# docker pull centos Pulling repository centos ^Croot@iZ28ikebrg6Z:~# ^C你看，它会去拉取，不过我中断了，因为我不需要，我的阿里云存储很金贵的。
Finding images
搜索一个镜像，你可以选择去docker hub的网站搜索，也可以选择在本地用命令行的方式进行。如下：
root@iZ28ikebrg6Z:~# docker search redmine NAME DESCRIPTION STARS OFFICIAL AUTOMATED sameersbn/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，描述，星级（越流行评分越高，提供参考)，是否有官方维护，是否自动化，这点我不是很能理解，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 Stackbrew project, and Automated repositories are Automated Builds that allow you to validate the source and content of an image.”
选一个pull下来就行了。
Building an image from a Dockerfile
通过Dockerfile来构建一个镜像。用vim写一个Dockerfile，内如如下：
#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，例如我们这个是给予Ubuntu：14.04的，MAINTANER是维护人员，比如说我，小曾，卖下萌。
RUN表示执行指令。
好，执行上述Dockerfile。
root@iZ28ikebrg6Z:~/docker# docker build -t="zengjinlong/sinatra:v2" . Sending build context to Docker daemon 2.56 kB Sending build context to Docker daemon Step 0 : FROM ubuntu:14.04 ---> 9cbaf023786c Step 1 : MAINTAINER zengjinlong <470910357@qq.com> ---> Running in c5674e71d7e4 ---> 224b40d4b89f Removing intermediate container c5674e71d7e4 Step 2 : RUN apt-get update && apt-get install -y ruby ruby-dev ---> Running in 5d6373cb79e6 Ign http://archive.ubuntu.com trusty InRelease Ign http://archive.ubuntu.com trusty-updates InRelease Ign http://archive.ubuntu.com trusty-security InRelease Ign http://archive.ubuntu.com trusty-proposed InRelease Get: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]
会耗费比较长的时间。
我们技术下一步的学习。
标记一个image
docker tag 5db5f8471261 ouruser/sinatra:devel
root@iZ28ikebrg6Z:~/docker# docker tag 224b40d4b89f zengjinlong/sinatra:v3
结果显示一下，
输出：
root@iZ28ikebrg6Z:~/docker# docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE <strong><span style="color:#ff0000;">zengjinlong/sinatra v3 </span></strong> 224b40d4b89f 13 minutes ago 192.8 MB ubuntu 14.10 2185fd50e2ca 2 days ago 237.2 MB ubuntu utopic 2185fd50e2ca 2 days ago 237.2 MB ubuntu trusty 9cbaf023786c 2 days ago 192.8 MB ubuntu latest 9cbaf023786c 2 days ago 192.8 MB ubuntu 14.04.1 9cbaf023786c 2 days ago 192.8 MB ubuntu 14.04 9cbaf023786c 2 days ago 192.8 MB ubuntu precise a9561eb1b190 2 days ago 120.2 MB ubuntu 12.04.5 a9561eb1b190 2 days ago 120.2 MB ubuntu 12.04 a9561eb1b190 2 days ago 120.2 MB centos centos5 504a65221a38 2 weeks ago 467.1 MB centos centos6 68edf809afe7 2 weeks ago 212.7 MB centos centos7 87e5b6b3ccc1 2 weeks ago 224 MB centos latest 87e5b6b3ccc1 2 weeks ago 224 MB ubuntu quantal c5881f11ded9 3 months ago 172.2 MB ubuntu 12.10 c5881f11ded9 3 months ago 172.2 MB ubuntu 13.04 463ff6be4238 3 months ago 169.4 MB ubuntu raring 463ff6be4238 3 months ago 169.4 MB ubuntu saucy 195eb90b5349 3 months ago 184.7 MB ubuntu 13.10 195eb90b5349 3 months ago 184.7 MB training/webapp latest 31fa814ba25a 4 months ago 278.8 MB ubuntu 10.04 3db9c44f4520 5 months ago 183 MB ubuntu lucid 3db9c44f4520 5 months ago 183 MB
上传我们的镜像到docker hub里面。
root@iZ28ikebrg6Z:~/docker# docker push zengjinlong/sinatra The push refers to a repository [zengjinlong/sinatra] (len: 1) Sending image list ^Croot@iZ28ikebrg6Z:~/docker#
演示一下就OK，不是很想在这里浪费时间。
删除本地镜像，因为毕竟占地方把。
root@iZ28ikebrg6Z:~/docker# docker rmi centos Untagged: centos:latest root@iZ28ikebrg6Z:~/docker# docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE zengjinlong/sinatra v3 224b40d4b89f 18 minutes ago 192.8 MB ubuntu 14.10 2185fd50e2ca 2 days ago 237.2 MB ubuntu utopic 2185fd50e2ca 2 days ago 237.2 MB ubuntu 14.04 9cbaf023786c 2 days ago 192.8 MB ubuntu latest 9cbaf023786c 2 days ago 192.8 MB ubuntu trusty 9cbaf023786c 2 days ago 192.8 MB ubuntu 14.04.1 9cbaf023786c 2 days ago 192.8 MB ubuntu 12.04.5 a9561eb1b190 2 days ago 120.2 MB ubuntu 12.04 a9561eb1b190 2 days ago 120.2 MB ubuntu precise a9561eb1b190 2 days ago 120.2 MB centos centos5 504a65221a38 2 weeks ago 467.1 MB centos centos6 68edf809afe7 2 weeks ago 212.7 MB centos centos7 87e5b6b3ccc1 2 weeks ago 224 MB ubuntu 12.10 c5881f11ded9 3 months ago 172.2 MB ubuntu quantal c5881f11ded9 3 months ago 172.2 MB ubuntu raring 463ff6be4238 3 months ago 169.4 MB ubuntu 13.04 463ff6be4238 3 months ago 169.4 MB ubuntu saucy 195eb90b5349 3 months ago 184.7 MB ubuntu 13.10 195eb90b5349 3 months ago 184.7 MB training/webapp latest 31fa814ba25a 4 months ago 278.8 MB ubuntu lucid 3db9c44f4520 5 months ago 183 MB ubuntu 10.04 3db9c44f4520 5 months ago 183 MB root@iZ28ikebrg6Z:~/docker# docker rmi centos:* Error response from daemon: No such image: centos:* 2014/10/16 15:38:58 Error: failed to remove one or more images root@iZ28ikebrg6Z:~/docker# docker rmi centos Error response from daemon: No such image: centos:latest 2014/10/16 15:39:03 Error: failed to remove one or more images root@iZ28ikebrg6Z:~/docker#
看来出了latest可以直接删除，其他的需要带上TAG才能指定删除。
好今天到这里。
