Registry仓库Harbor的部署与简介

Harbor 是Vmware公司开源的企业级DockerRegistry管理项目，开源项目地址：https://github.com/vmware/harbor。Harbor的所有组件都在Docker中部署，所以Harbor可使用Docker Compose快速部署。（由于Harbor是基于Docker Registry V2版本，所以docker版本至少1.10.0、docker-compose版本至少1.6.0）

主要组件：

（1）proxy：nginx前端代理，分发前端页面ui访问和镜像上传和下载流量；
（2）ui：提供前端页面和后端API，底层使用mysql数据库；
（3）registry：镜像仓库，负责存储镜像文件，当镜像上传完毕后通过hook通知ui创建repository，registry的token认证也是通过ui组件完成；
（4）adminserver是系统的配置管理中心附带检查存储用量，ui和jobserver启动时候回需要加载adminserver的配置
（5）jobsevice：负责镜像复制工作，和registry通信，从一个registry pull镜像然后push到另一个registry，并记录job_log；
（6）log：日志汇总组件，通过docker的log-driver把日志汇总到一起。

部署过程：

下面采用的是下载tgz离线安装包的方式（假设docker、docker-compose都已经部署好）

执行./install.sh，Harbor服务就会根据当期目录下的docker-compose.yml开始下载依赖的镜像，检测并通过docker-compose启动各服务
各服务以容器的形式存在：nginx、vmware/harbor-jobservice、vmware/harbor-db、library/registry、harbor-ui、vmware/harbor-log
启动完成后，访问http://xx.xx.xx.xx:80（端口映射可以去docker-compose.yml中修改）
以后执行docker-compose start/stop命令或者 docker-compose up/down -v就可以快速开关服务。

主要功能：
（1）Docker Registry管理UI
部分配置项可以在UI页面上直接修改，如邮件服务器配置、LDMA配置等
（2）角色访问控制
除了admin，用户分为三种角色：项目管理员（MDRWS）、开发人员（RWS）和访客（RS）
M:管理、D:删除、R:读取、W:写入、S:查询
用户只能新建自己的项目，并push/pull自己所在项目的镜像，其他人的私有仓库都不能操作。
用户创建私有项目project_name后，只有该用户允许的用户才向该项目中上传镜像：

$ docker login xx.xx.xx.xx:80
Username: admin
Password:
Login Succeeded
$ docker tag XXX xx.xx.xx.xx:80/project_name/container_name
$ docker push xx.xx.xx.xx:80/project_name/container_name
