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。
