devops-部署Harbor实现私有Docker镜像仓库

概述

Harbor是一个开源注册中心，它使用策略和基于角色的访问控制来保护工件，确保镜像被扫描并且没有漏洞，并将镜像签名为可信的。Harbor是CNCF的一个毕业项目，它提供了合规性、性能和互操作性，帮助你在Kubernetes和Docker等云原生计算平台上一致、安全地管理工件。Harbor可以安装在任何Kubernetes环境或支持Docker的系统上。

下载

下载最新的Harbor离线安装包。选择适合你操作系统的版本 ，一般是.tar.gz格式的压缩包。例如，下载后的文件名为harbor - offline - installer - v2.5.0.tgz
下载地址

将下载的安装包传输到服务器上，例如使用scp（在Linux系统之间）或者WinSCP（在Windows和Linux之间）等工具。

配置

解压，例如tar -zxvf harbor - offline - installer - v2.5.0.tgz
进入解压后的harbor目录，其中包含一个harbor.yml.tmpl文件，这是Harbor的配置模板文件。
复制一份配置模板文件并命名为harbor.yml，例如：
cp harbor.yml.tmpl harbor.yml

编辑harbor.yml文件，主要配置项包括：
主机名（hostname）：将hostname设置为服务器的IP地址或域名，如hostname: 192.168.1.100。如果要使用HTTPS，还需要配置证书相关选项。
存储路径（data_volume）：可以修改数据存储的路径，默认路径是/data，例如可以将其更改为/mnt/harbor - data，即data_volume: /mnt/harbor - data。
账户密码（harbor_admin_password）：设置Harbor管理员账户的密码，如harbor_admin_password: your - password。

其他配置（可选）

• 如果需要配置外部数据库（默认使用内置数据库）、LDAP认证等，可以在harbor.yml文件中按照官方文档的说明进行配置。

详细配置见以下内容：

# Configuration file of Harbor# The IP address or hostname to access admin UI and registry service.
# DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.

# Trivy DB contains vulnerability information from NVD, Red Hat, and many other upstream vulnerability databases.
# It is downloaded by Trivy from the GitHub release page https://github.com/aquasecurity/trivy-db/releases and cached
# in the local file system. In addition, the database contains the update timestamp so Trivy can detect whether it
# should download a newer version from the Internet or use the cached one. Currently, the database is updated every
# 12 hours and published as a new release to GitHub.

安装

1. 执行安装脚本

   • 在harbor目录下，执行./install.sh脚本。这个脚本会根据harbor.yml文件中的配置来启动Harbor相关的容器。安装过程可能需要一些时间，因为它需要下载和启动多个容器组件，如Harbor的核心服务、数据库、Redis等。
     
     

2. 验证安装

   • 当安装完成后，可以通过浏览器访问配置的hostname和端口来访问Harbor的Web界面。例如，在浏览器中输入http://192.168.1.100:80（根据实际配置的主机名和端口），如果能够看到Harbor的登录界面，说明部署成功。可以使用默认的管理员账号admin和在harbor.yml文件中设置的密码进行登录，然后开始使用Harbor来管理容器镜像。

安装后生成的文件

访问管理控制台
http://192.168.79.30/harbor/projects

使用和维护Harbor

1. 推送和拉取镜像
   • 在客户端机器上，需要将Harbor的服务器地址添加到Docker的信任列表中。例如，如果Harbor的服务器是192.168.79.30:80，可以在客户端机器的/etc/docker/daemon.json文件中添加以下内容（如果文件不存在可以创建）：

     • {"insecure - registries": ["192.168.79.30:80"]
       }
       

   • 然后重启客户端机器的Docker服务。之后就可以将本地镜像推送到Harbor仓库，例如：docker push 192.168.79.30:80/your - image - name，也可以从Harbor仓库拉取镜像：docker pull 192.168.79.30:80/your - image - name。
2. 备份和更新Harbor
   定期备份Harbor的数据，包括存储在data_volume路径下的数据以及数据库备份（如果使用外部数据库）。同时，关注Harbor官方网站的更新信息，按照官方的更新指南及时更新Harbor版本，以确保系统的安全性和功能的完整性。
