在前边的博客中我们说到docker的架构由docker客户端、服务端以及仓库组成;docker仓库就是用来存放镜像的地方;其实docker registry我们理解为存放docker镜像仓库的仓库比较准确吧;因为docker的镜像仓库通常是把同一类的镜像用不同的版本来区别,而registry则是用来存放这些仓库的仓库;默认安装docker都是从dockerhub镜像仓库下载镜像;其实在生产环境中,我们很少去公有仓库上下载镜像,原因之一是公有仓库中的镜像在生产环境中使用,有些不适配,通常我们是去公有仓库下载基础镜像,然后基于基础镜像构建适合自己生产环境中的镜像;其次公有仓库镜像有很多都不是安全的镜像,这么说吧,我们不确定自己下载的镜像是否有后门,是否有挖矿代码,所以基于种种因素,我们还是有必要搭建自己私有的镜像仓库;今天我们就来聊一聊docker的私有镜像仓库的搭建; 1、查看docker-distribution包简介 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 [root@docker_registry ~]# yum info docker-distribution Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Available Packages Name : docker-distribution Arch : x86_64 Version : 2.6.2 Release : 2.git48294d9.el7 Size : 3.5 M Repo : extras/7/x86_64 Summary : Docker toolset to pack, ship, store, and deliver content URL : https://github.com/docker/distribution License : ASL 2.0 Description : Docker toolset to pack, ship, store, and deliver content [root@docker_registry ~]# 提示:docker-distribution这个包就是提供简单仓库服务软件实现; 2、安装docker-distribution 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 [root@docker_registry ~]# yum install -y docker-distribution Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help). The program yum-complete-transaction is found in the yum-utils package. --> Running transaction check ---> Package docker-distribution.x86_64 0:2.6.2-2.git48294d9.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================== Package Arch Version Repository Size =================================================================================================================== Installing: docker-distribution x86_64 2.6.2-2.git48294d9.el7 extras 3.5 M Transaction Summary =================================================================================================================== Install 1 Package Total download size: 3.5 M Installed size: 12 M Downloading packages: docker-distribution-2.6.2-2.git48294d9.el7.x86_64.rpm | 3.5 MB 00:00:03 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : docker-distribution-2.6.2-2.git48294d9.el7.x86_64 1/1 Verifying : docker-distribution-2.6.2-2.git48294d9.el7.x86_64 1/1 Installed: docker-distribution.x86_64 0:2.6.2-2.git48294d9.el7 Complete!
