docker私有仓库Harbor

目录

前言

Harbor是VMware公司开源的企业级Docker Registry项目

1.Harbor的优势

1.基于角色控制:有管理员与普通用户,可赋权普通用户,比如只能上传和下载,可根据项目来进行操作和管理
2.基于镜像的复制策略:也与权限相关,比如有只一-些用户与组才能对此项目进行相对应的操作
3.支持LDAP/AD: 域控制,比如南京去下载北京harbor
私有仓库的镜像,两端打上,局域网的地址,连接在一一块,数据信息的传输通过一条隧道,会通过两层加密,第一层为隧道
加密,第二层为数据加密,安全可靠
4.图像删除和垃圾收集:即回收站机制
5.图形UI:具有统计功能,比如访问量与镜像^下载热度
6.审计:日志,这里意义不大,主要还是借助于ELK
7.RESTful API:定义Web 语言规范的格式,方便调用Harbor 的接口,也便于二次开发

1.2Harbor的构成

组件 作用
Proxy 通过一个前置的反向代理统一接收浏览器、Docker客户端的请求,并将请求转发给后端不同的服务
Registry (核心组件)负责储存Docker镜像,并处理docker push/pull命令
Core services Harbor的核心功能, 包括UI、webhook、 token服务
Database 为core services提供数据库服务
Log collector 负责收集其他组件的log,供日后进行分析

这些组件都是以容器封装的方式,使用docker-compose编排管理完成的
registry是代码仓库

2.3关于 Harbor.cfg 配置文件中有两类参数

2.3.1、所需参数

如果用户更新它们并运行 install.sh脚本重新安装 Harbor,参数将生效。具体参数如下:

**hostname:**用于访问用户界面和 register 服务。它应该是目标机器的 IP 地址或完全限 定的域名(FQDN)
例如 192.168.35.40 或 hub.klj.cn。不要使用 localhost 或 127.0.0.1 为主机名。
ui_url_protocol:(http 或 https,默认为 http)用于访问 UI 和令牌/通知服务的协议。如果公证处于启用状态,则此参数必须为 https。(身份验证时会向Mysql数据库进行比对,然后授予令牌)
**max_job_workers:**镜像复制作业线程。
db_password:用于db_auth 的MySQL数据库root 用户的密码。
**customize_crt:**该属性可设置为打开或关闭,默认打开。打开此属性时,准备脚本创建私钥和根证书,用于生成/验证注册表令牌。当由外部来源提供密钥和根证书时,将此属性设置为 off。
**ssl_cert:**SSL 证书的路径,仅当协议设置为 https 时才应用。
ssl_cert_key:SSL 密钥的路径,仅当协议设置为 https 时才应用。
secretkey_path:用于在复制策略中加密或解密远程 register 密码的密钥路径。

2.3.2、可选参数

这些参数对于更新是可选的,即用户可以将其保留为默认值,并在启动 Harbor 后在 Web UI 上进行更新。
如果进入 Harbor.cfg,只会在第一次启动 Harbor 时生效,随后对这些参数的更新,Harbor.cfg 将被忽略。
注意:如果选择通过UI设置这些参数,请确保在启动Harbour后立即执行此操作。具体来说,必须在注册或在 Harbor 中创建任何新用户之前设置所需的auth_mode。当系统中有用户时(除了默认的 admin 用户),auth_mode 不能被修改。具体参数如下:

Email:Harbor需要该参数才能向用户发送“密码重置”电子邮件,并且只有在需要该功能时才需要。
请注意,在默认情况下SSL连接时没有启用。如果SMTP服务器需要SSL,但不支持STARTTLS,那么应该通过设置启用SSL email_ssl = TRUE。
harbour_admin_password:管理员的初始密码,只在Harbour第一次启动时生效。之后,此设置将被忽略,并且应 UI中设置管理员的密码。
请注意,默认的用户名/密码是 admin/Harbor12345。
auth_mode:使用的认证类型,默认情况下,它是 db_auth,即凭据存储在数据库中。对于LDAP身份验证(以文件形式验证),请将其设置为 ldap_auth。
self_registration:启用/禁用用户注册功能。禁用时,新用户只能由 Admin 用户创建,只有管理员用户可以在 Harbour中创建新用户。
注意:当 auth_mode 设置为 ldap_auth 时,自注册功能将始终处于禁用状态,并且该标志被忽略。
Token_expiration:由令牌服务创建的令牌的到期时间(分钟),默认为 30 分钟。
project_creation_restriction:用于控制哪些用户有权创建项目的标志。默认情况下, 每个人都可以创建一个项目。如果将其值设置为“adminonly”,那么只有 admin 可以创建项目。
verify_remote_cert:打开或关闭,默认打开。此标志决定了当Harbor与远程 register 实例通信时是否验证 SSL/TLS 证书。将此属性设置为 off 将绕过 SSL/TLS 验证,这在远程实例具有自签名或不可信证书时经常使用。

2.部署Harbor服务

2.1下载 Harbor 安装程序

wget http:// harbor.orientsoft.cn/harbor-1.2.2/harbor-offline-installer-v1.2.2.tgz
或者上传压缩包harbor-offline-installer-v1.2.2.tgz
tar zxvf harbor-offline-installer-v1.2.2.tgz -C /usr/local/

2.2配置 Harbor参数文件

vim /usr/local/harbor/harbor.cfg
5 hostname = 192.168.226.128		##修改成本机地址

2.3启动 Harbor

启动之前先确认Docker-Compose 版本安装是否成功

[root@harbor ~]#  docker-compose -v
docker-compose version 1.21.1, build 5a3f1a3
[root@harbor ~]# sh /usr/local/harbor/install.sh		##启动启动 Harbor;docker-compose中已定义相关脚本

✔ ----Harbor has been installed and started successfully.----

添加项目并且填写项目名称mytest

2.6命令行登录harbor

1.Harbor 服务器基于本地操作
使用 Docker 命令在本地通过 127.0.0.1 来登录和推送镜像。默认情况下,Register 服务器在端口 80 上侦听。

[root@harbor harbor]# docker login -u admin -p Harbor12345 http://127.0.0.1	##//登录

2.Harbor 服务器非本地操作
以上操作都是在 Harbor 服务器本地操作。如果其他客户端上传镜像到 Harbor,就会报
如下错误。出现这问题的原因 Docker Registry 交互默认使用的是 HTTPS,但是搭建私有镜
像默认使用的是 HTTP 服务,所以与私有镜像交互时出现以下错误。

2.8维护管理Harbor

可以使用 docker-compose 来管理 Harbor。一些有用的命令如下所示,必须在与docker-compose.yml 相同的目录中运行。
修改 Harbor.cfg 配置文件
要更改 Harbour 的配置文件时,请先停止现有的 Harbour 实例并更新 Harbor.cfg;然后运行 prepare 脚本来填充配置;最后重新创建并启动 Harbour 的实例。
