    Harbor私有仓库

    Harbor简介:

    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 提供了以下主要功能和特性:

    1. 容器镜像存储:Harbor 允许用户存储 Docker 镜像,使其能够轻松地管理和分享容器镜像。
    2. 访问控制:Harbor 支持灵活的访问控制策略,可以定义用户和团队对镜像的访问权限,包括读取和写入权限。这有助于维护镜像的安全性和隐私性。
    3. 复制和同步:Harbor 支持镜像的复制和同步功能,允许用户将镜像从一个 Harbor 实例复制到另一个,以便在多个地理位置或环境之间共享。
    4. 漏洞扫描:Harbor 集成了漏洞扫描工具,可以检查镜像中的漏洞,并提供关于安全问题的报告,有助于确保容器镜像的安全性。
    5. 存储策略:用户可以配置存储策略,包括镜像的保留策略和自动清理机制,以控制存储资源的使用。
    6. 多租户支持:Harbor 支持多租户架构,允许不同团队或项目在同一个 Harbor 实例上创建和管理他们自己的私有镜像仓库。
    7. 活动审计:Harbor 记录了所有对镜像仓库的操作,以提供审计功能,帮助跟踪谁在何时访问和修改了镜像。
    8. LDAP/AD集成:Harbor 支持与LDAP和Active Directory集成,方便组织内部管理用户和团队的访问权限。

    优缺点:

    优点:

    1. 安全性:Harbor 提供强大的访问控制和漏洞扫描功能,有助于确保镜像的安全性。
    2. 隐私:组织可以轻松创建和管理私有仓库,控制其镜像的访问权限,确保敏感数据不会泄露。
    3. 灵活性:Harbor 可以在多云环境或本地部署,适用于各种部署场景。
    4. 多租户:支持多租户,使不同项目或团队能够在同一实例上管理他们自己的仓库。
    5. 容器镜像管理:提供了丰富的容器镜像管理功能,包括复制、同步、存储策略等。

    缺点:

    1. 维护成本:部署和维护 Harbor 需要一定的工作量和资源,尤其是在大规模使用时。
    2. 学习曲线:对于新用户来说,配置和管理 Harbor 可能需要一些学习和时间。
    3. 性能:在处理大量镜像时,性能可能成为一个问题,需要适当的硬件和调优。

    通过IP访问harbor的web界面

    在这里插入图片描述
    在这里插入图片描述

    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
    7.将harbor设置为开机自启
    //由于想要关闭或开启harbor需要进入到有docker-compose.yml文件的目录下执行,所以我们将该命令放到虚拟机启动最后执行的一个文件中去,也就是/etc/rc.local文件中
    
    [root@harbor harbor]# vim /etc/rc.local 
    [root@harbor harbor]# head -5 /etc/rc.local
    #!/bin/bash
    cd /usr/local/harbor/ && docker-compose start
    # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
    #
    # It is highly advisable to create own systemd services or udev rules
    [root@harbor harbor]# ll /etc/rc.local
    lrwxrwxrwx. 1 root root 13 Mar 24  2020 /etc/rc.local -> rc.d/rc.local
    [root@harbor harbor]# chmod +x /etc/rc.d/rc.local
    [root@harbor harbor]# ll /etc/rc.d/rc.local 
    -rwxr-xr-x. 1 root root 520 Nov  7 22:29 /etc/rc.d/rc.local
    
    //将cd /usr/local/harbor/ && docker-compose start写入到这个文件中后,他就会在开启这个虚拟机的时候执行进入/usr/local/harbor/目录中执行开启harbor的命令

    8.登录到docker的私有镜像仓库(harbor)
    //在登录我们的harbor私有仓库时,需在/etc/docker/daemon.json文件中添加harbor仓库的信息,指定我们设置的harbor.com这个主机名
    [root@docker local]# vim /etc/docker/daemon.json 
    [root@docker local]# cat /etc/docker/daemon.json
    {
      "dns": ["114.114.114.114"],
      "insecure-registries": ["harbor.com"],   //添加此行 
      "registry-mirrors": ["https://d5qafvab.mirror.aliyuncs.com"]
    }
    [root@docker local]# systemctl restart docker.service    //重启生效
    
    [root@docker ~]# docker login harbor.com   //登录到私有镜像仓库
    Username: admin
    Password:                    //此处密文密码为Harbor.com
    Authenticating with existing credentials...
    WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
    Configure a credential helper to remove this warning. See
    https://docs.docker.com/engine/reference/commandline/login/#credentials-store
    
    Login Succeeded   //登录成功

    10.测试,以拉取的镜像制作一个容器
    [root@docker ~]# docker run -d -p 80:80 harbor.com/library/nginx:v0.1
    ac1593a13a916fe20acf57a14bb5cb67b998d449e5d6b080a98c6dd29099f735

    在浏览器中通过80端口进行访问
    在这里插入图片描述
    访问成功

    11.错误报告

    如果在登录harbor私有镜像仓库时出现核心服务不可用时可以尝试以下几种方法:
    方法一:
    重新执行一遍install.sh脚本后再次登录尝试

    方法二:
    重启Harbor服务

    docker-compose down
    docker-compose up -d
    
    
    总的来说,Harbor 私有仓库是一个功能丰富、安全可靠的容器镜像管理工具,适用于组织和开发团队,特别是那些需要严格控制镜像访问权限和确保安全性的情况。然而,它需要考虑到部署和维护成本,以及对性能的关注。
