阿里云部署Docker(5)----管理和发布您的镜像

简介:

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。

本文欢迎转载,但要尊重本人劳动成果,转载注明转自“http://blog.csdn.net/minimicall/” http://blog.csdn.net/minimicall/article/details/40147207

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。

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


如何获取一个新的镜像。我们知道当我们运行一个镜像的时候,如果这个镜像例如centos在本地没有,docker会自动的去远端库查询和下载。但是这种临时的下载明显是费时间的,我们可以不可以提前去下载呢?可以,使用docker pull拉取指令。

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

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" .

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:

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。
