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。

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。

Project Harbor是一个开源的可信云本地注册项目,用于存储、标记和扫描上下文。
Harbor扩展了开源Docker分发版,增加了用户通常需要的功能,如安全、身份和管理。
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

Harbor的核心功能是存储和管理Artifact
访问控制:访问控制是多个用户使用同一个仓库存储Artifact时的基本需求,也是Harbor早期版本提供的主要功能之一
镜像签名:镜像在本质上是软件的封装形式,从安全角度来看,开发人员在部署镜像前需要保证镜像内容的完整性(integrity)
镜像扫描:容器镜像打包了代码、软件及其所需的运行环境,已发布的软件及其依赖的库都可能存在安全漏洞
高级管理功能:Harbor在版本迭代中还根据社区反馈,为管理员及用户提供了很多高级管理功能以支持更加复杂的使用场景,包括Artifact复制策略、存储配额管理、Tag保留策略(Artifact保留策略)和垃圾回收等

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,您可以使用一个YAML文件来配置应用程序的服务。然后,使用一个命令创建并启动配置中的所有服务。

Harbor部署

提前进入Harbor官方文档(https://github.com/goharbor/harbor)下载harbor-offline-installer-v2.5.3这个包,操作如下:
在左上角输入harbor搜索

分别开启两台机子,一台为客户端,一台为镜像仓库端
client为客户端,harbor为镜像仓库端
需要保证两台机子都要有docker

客户端: [root@localhost ~]# hostnamectl set-hostname client [root@localhost ~]# bash [root@client ~]# which docker /usr/bin/docker [root@client yum.repos.d]# ls CentOS-Base.repo  docker-ce.repo [root@client yum.repos.d]#  scp docker-ce.repo 192.168.222.251:/etc/yum.repos.d/ The authenticity of host '192.168.222.251 (192.168.222.251)' can't be established.

使用Harbor的注意事项:

  1. 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
  2. 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
  3. 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
  4. 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
