一：简介
Harbor是一个用于存储和分发Docker镜像的企业级Registry服务器。

镜像的存储harbor使用的是官方的docker registry(v2命名是distribution)服务去完成。harbor在docker distribution的基础上增加了一些安全、访问控制、管理的功能以满足企业对于镜像仓库的需求。harbor以docker-compose的规范形式组织各个组件，并通过docker-compose工具进行启停。

docker的registry是用本地存储或者s3都是可以的，harbor的功能是在此之上提供用户权限管理、镜像复制等功能，提高使用的registry的效率。Harbor的镜像拷贝功能是通过docker registry的API去拷贝，这种做法屏蔽了繁琐的底层文件操作、不仅可以利用现有docker registry功能不必重复造轮子，而且可以解决冲突和一致性的问题。
二：Harbor架构

三：主要组件
Proxy：对应启动组件nginx。它是一个nginx反向代理，代理Notary client（镜像认证）、Docker client（镜像上传下载等）和浏览器的访问请求（Core Service）给后端的各服务；
UI（Core Service）：对应启动组件harbor-ui。底层数据存储使用mysql数据库，主要提供了四个子功能：
UI：一个web管理页面ui；
API：Harbor暴露的API服务；
Auth：用户认证服务，decode后的token中的用户信息在这里进行认证；auth后端可以接db、ldap、uaa三种认证实现；
Token服务（上图中未体现）：负责根据用户在每个project中的role来为每一个docker push/pull命令issuing一个token，如果从docker client发送给registry的请求没有带token，registry会重定向请求到token服务创建token。
Registry：对应启动组件registry。负责存储镜像文件，和处理镜像的pull/push命令。Harbor对镜像进行强制的访问控制，Registry会将客户端的每个pull、push请求转发到token服务来获取有效的token。
Admin Service：对应启动组件harbor-adminserver。是系统的配置管理中心附带检查存储用量，ui和jobserver启动时候需要加载adminserver的配置；
Job Sevice：对应启动组件harbor-jobservice。负责镜像复制工作的，他和registry通信，从一个registry pull镜像然后push到另一个registry，并记录job_log；
Log Collector：对应启动组件harbor-log。日志汇总组件，通过docker的log-driver把日志汇总到一起；
Volnerability Scanning：对应启动组件clair。负责镜像扫描
Notary：对应启动组件notary。负责镜像认证
DB：对应启动组件harbor-db，负责存储project、 user、 role、replication、image_scan、access等的metadata数据。
四：安装

1、安装python-pip
yum -y install epel-release
yum -y install python-pip
升级
python -m pip install -U pip

2、安装docker-compose
pip install docker-compose
待安装完成后，执行查询版本的命令，即可安装docker-compose
docker-compose version

./install.sh

可以使用docker-compose来管理Harbor的生命周期。 一些有用的命令列出如下:
docker-compose ps 查看
docker-compose stop 停止
docker-compose start 启动
docker-compose down 删除，利用./install.sh可以重新安装

解决办法：
pip uninstall urllib3
pip uninstall chardet
