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。

项目Harbor是一个开源的、受信任的云原生的仓库项目，用来存储、登录（用户管理）和查找镜像。

Harbor扩展了开源的Docker Distribution的功能，通过添加用户通常需要的功能，如安全、认证和管理。

Harbor支持高级特性，如用户管理、访问控制、活动监视和主从复制。

Harbor的功能

Feathers：

• 用户的登录与校验
• 安全性和漏洞分析
• 日志审计
• 身份验证和基于角色的访问控制
• 镜像实例的主从复制（高可用）
• 可扩展API和图形UI
• 支持的语言（当前支持英语和中文）

Docker Compose（编排工具）

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的单机编排工具(Docker compose)来实现。

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。
