Harbor镜像仓库部署

Harbor

无论是使用Docker-distribution去自建仓库，还是通过官方镜像跑容器的方式去自建仓库，通过前面的演示我们可以发现其是非常的简陋的，还不如直接使用官方的Docker Hub去管理镜像来得方便，至少官方的Docker Hub能够通过web界面来管理镜像，还能在web界面执行搜索，还能基于Dockerfile利用Webhooks和Automated Builds实现自动构建镜像的功能，用户不需要在本地执行docker build，而是把所有build上下文的文件作为一个仓库推送到github上，让Docker Hub可以从github上去pull这些文件来完成自动构建。

但无论官方的Docker Hub有多强大，它毕竟是在国外，所以速度是最大的瓶颈，我们很多时候是不可能去考虑使用官方的仓库的，但是上面说的两种自建仓库方式又十分简陋，不便管理，所以后来就出现了一个被 CNCF 组织青睐的项目，其名为Harbor。

Harbor简介

Harbor是由VMWare在Docker Registry的基础之上进行了二次封装，加进去了很多额外程序，而且提供了一个非常漂亮的web界面。

Harbor是一个开源可信的云原生的仓库项目，用于存储、用户管理和查找镜像。
Harbor通过添加用户通常需要的功能，如安全、身份和管理，扩展了开源Docker分发版。
Harbor支持高级特性，如用户管理、访问控制、活动监视和实例之间的复制。

Harbor的功能

多租户内容签名和验证
安全性和漏洞分析
审计日志记录
身份集成和基于角色的访问控制
实例之间的映像复制
可扩展API和图形UI
国际化(目前为中英文化)

Docker compose

Harbor在物理机上部署是非常难的，而为了简化Harbor的应用，Harbor官方直接把Harbor做成了在容器中运行的应用，而且这个容器在Harbor中依赖类似redis、mysql、pgsql等很多存储系统，所以它需要编排很多容器协同起来工作，因此VMWare Harbor在部署和使用时，需要借助于Docker的单机编排

Compose是一个用于定义和运行多容器Docker应用程序的工具。使用Compose，您可以使用YAML文件来配置应用程序的服务。然后，通过一个命令，您可以创建并启动配置中的所有服务。

使用Harbor的注意事项：

在客户端上传镜像时一定要记得执行docker login进行用户认证，否则无法直接push
在客户端使用的时候如果不是用的https则必须要在客户端的/etc/docker/daemon.json配置文件中配置insecure-registries参数
数据存放路径应在配置文件中配置到一个容量比较充足的共享存储中
Harbor是使用docker-compose命令来管理的，如果需要停止Harbor也应用docker-compose stop来停止，其他参数请–help
