【harbor】离线安装2.9.0-arm64架构服务制作和升级部署

news2024/11/14 11:21:27

harbor官网地址:Harbor

参考文档可以看这里:部署 harbor 2.10.1 arm64 - 简书。

前提环境准备: 安装docker 和 docker-compose

先拉arm64架构的harbor相关镜像

docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/harbor-registryctl:v2.9.0 
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/nginx-photon:v2.9.0 
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/registry-photon:v2.9.0
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/prepare:v2.9.0    
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/harbor-portal:v2.9.0    
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/harbor-log:v2.9.0
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/harbor-exporter:v2.9.0
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/redis-photon:v2.9.0
docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/trivy-adapter-photon:v2.9.0

docker pull --platform=linux/arm64 ghcr.io/octohelm/harbor/harbor-jobservice:v2.9.0 
  1. 将相关镜像修改名称

docker tag ghcr.io/octohelm/harbor/harbor-registryctl:v2.9.0 goharbor/harbor-registryctl:v2.9.0
docker tag ghcr.io/octohelm/harbor/nginx-photon:v2.9.0 goharbor/nginx-photon:v2.9.0
docker tag ghcr.io/octohelm/harbor/registry-photon:v2.9.0 goharbor/registry-photon:v2.9.0
docker tag ghcr.io/octohelm/harbor/prepare:v2.9.0 goharbor/prepare:v2.9.0     
docker tag ghcr.io/octohelm/harbor/harbor-portal:v2.9.0 goharbor/harbor-portal:v2.9.0    
docker tag ghcr.io/octohelm/harbor/harbor-log:v2.9.0 goharbor/harbor-log:v2.9.0
docker tag ghcr.io/octohelm/harbor/harbor-exporter:v2.9.0 goharbor/harbor-exporter:v2.9.0
docker tag ghcr.io/octohelm/harbor/redis-photon:v2.9.0 goharbor/redis-photon:v2.9.0
docker tag ghcr.io/octohelm/harbor/trivy-adapter-photon:v2.9.0 goharbor/trivy-adapter-photon:v2.9.0
docker tag ghcr.io/octohelm/harbor/harbor-core:v2.9.0 goharbor/harbor-core:v2.9.0
docker tag ghcr.io/octohelm/harbor/harbor-db:v2.9.0 goharbor/harbor-db:v2.9.0
docker tag ghcr.io/octohelm/harbor/harbor-jobservice:v2.9.0 goharbor/harbor-jobservice:v2.9.0
  1. 将harbor相关镜像导出为tar包

docker save -o goharbor-harbor-registryctl-v2.9.0.tar goharbor/harbor-registryctl:v2.9.0
docker save -o goharbor-nginx-photon-v2.9.0.tar goharbor/nginx-photon:v2.9.0
docker save -o goharbor-registry-photon-v2.9.0.tar goharbor/registry-photon:v2.9.0
docker save -o goharbor-prepare-v2.9.0.tar goharbor/prepare:v2.9.0
docker save -o goharbor-harbor-portal-v2.9.0.tar goharbor/harbor-portal:v2.9.0
docker save -o goharbor-harbor-log-v2.9.0.tar goharbor/harbor-log:v2.9.0
docker save -o goharbor-harbor-exporter-v2.9.0.tar goharbor/harbor-exporter:v2.9.0
docker save -o goharbor-redis-photon-v2.9.0.tar goharbor/redis-photon:v2.9.0
docker save -o goharbor-trivy-adapter-photon-v2.9.0.tar goharbor/trivy-adapter-photon:v2.9.0
docker save -o goharbor-harbor-core-v2.9.0.tar goharbor/harbor-core:v2.9.0
docker save -o goharbor-harbor-db-v2.9.0.tar goharbor/harbor-db:v2.9.0
docker save -o goharbor-harbor-jobservice-v2.9.0.tar goharbor/harbor-jobservice:v2.9.0

将harbor相关的tar包全部合并成一个gz包

tar -czvf harbor.v2.9.0-arm64.tar.gz *.tar

下载官网离线安装包x86的版本,

主要是为了拿里面的配置文件,将里面的harbor.v2.9.0.tar.gz,替换我们上面制作好的harbor.v2.9.0-arm64.tar.gz镜像包即可。

x86版本的下载地址:  https://github.com/goharbor/harbor/releases/download/v2.9.0/harbor-offline-installer-v2.9.0.tgz

  1. 替换好后重新打包全部合并成一个gz包

tar -czvf harbor-offline-installer-v2.9.0-arm64.tar.gz harbor

image.png

开始安装

解压文件 tar -zxf harbor-offline-installer-v2.9.0.tgz 

然后修改habor.yaml的配置文件

# Trivy configuration
#
# 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.
trivy:
  # ignoreUnfixed The flag to display only fixed vulnerabilities
  ignore_unfixed: false
  # skipUpdate The flag to enable or disable Trivy DB downloads from GitHub
  #
  # You might want to enable this flag in test or CI/CD environments to avoid GitHub rate limiting issues.
  # If the flag is enabled you have to download the `trivy-offline.tar.gz` archive manually, extract `trivy.db` and
  # `metadata.json` files and mount them in the `/home/scanner/.cache/trivy/db` path.
  skip_update: false
  #
  # The offline_scan option prevents Trivy from sending API requests to identify dependencies.
  # Scanning JAR files and pom.xml may require Internet access for better detection, but this option tries to avoid it.
  # For example, the offline mode will not try to resolve transitive dependencies in pom.xml when the dependency doesn't
  # exist in the local repositories. It means a number of detected vulnerabilities might be fewer in offline mode.
  # It would work if all the dependencies are in local.
  # This option doesn't affect DB download. You need to specify "skip-update" as well as "offline-scan" in an air-gapped environment.
  offline_scan: false
  #
  # Comma-separated list of what security issues to detect. Possible values are `vuln`, `config` and `secret`. Defaults to `vuln`.
  security_check: vuln
  #
  # insecure The flag to skip verifying registry certificate
  insecure: false
  # github_token The GitHub access token to download Trivy DB
  #
  # Anonymous downloads from GitHub are subject to the limit of 60 requests per hour. Normally such rate limit is enough
  # for production operations. If, for any reason, it's not enough, you could increase the rate limit to 5000
  # requests per hour by specifying the GitHub access token. For more details on GitHub rate limiting please consult
  # https://docs.github.com/rest/overview/resources-in-the-rest-api#rate-limiting
  #
  # You can create a GitHub token by following the instructions in

配置

执行: .prepare

启动

执行命令 docker-compose up -d 或者 ./install.sh也一样。
install.sh脚本包含了:docker load、./prepare、docker-compose up -d3个命令。

 这样就安装完成;

安装时碰到一些小问题是: install.sh中的 docker load -i habor...gz文件的时候报错,我是直接注释了docker load -i  ,, 自己直接解压压缩包 然后手动一个一个镜像执行docker load -i 其他的没有碰到到什么问题。

Harbor的登录

用户名和密码使用默认的在habor.yaml文件中有:

登录失败遇到的问题

登录提示核心功能启动失败,查看日志,发现redis没有成功

链接不了,查看docker logs redis_container_id

这个应该是和系统内存页分配相关的问题,就是redis和系统提供的参数不匹配

直接修改docker-compose.yaml把redis镜像换成其他版本,arm系统兼容版本就可以了,我用的是arm 7.0版本

登录成功!

关停Habor 

docker-compose down

修改配置更新操作

如果修改了配置,那么就需要关停,然后重新配置,安装更新

docker-compose down
./prepare
docker-compose up -d

问题1 - harbor中的hostname 和 external_url

如果harbor的认证服务地址我们是通过 external_url 配置的,那么harbor主机ip地址变化时,无须对harbor配置进行调整。
否则,如果hostname配置的是 域名,那么也无须对harbor配置进行调整。
否则,如果hostname配置的是内网ip,那么就需要更改harbor配置中的hostname属性。
然后执行下面命令:

docker-compose down
./prepare
docker-compose up -d

客户端如果时通过内网ip来访问 harbor的话,也需要同时修改 daemon.json文件配置,并重启docker

问题2 - 重置harbor的admin密码

harbor的admin密码存储在 postgresql数据库中。如果忘记密码的话,可以使用SQL客户端连接postgre数据库,删除admin密码即可。

具体步骤:

  • 停止harbor服务:docker-compose down
  • 修改docker-compose文件中:postgresql服务的端口导出:如ports: -5432:5432(5432是harbor postgresql的缺省端口)
  • 重启harbor:docker-compose up -d
  • 使用任意客户端工具连接postgresql数据库,数据库缺省密码为 postgres / root123,数据库:registry
  • 更新密码:update harbor_user set password='',salt='' where username='admin'
  • 再次停止harbor服务:docker-compose down
  • 修改harbor.yml文件中登录密码
  • 重新生成配置文件 ./prepare
  • 再次重启harbor:docker-compose up -d

开启Https功能

  首先创建私钥和自签名证书:可以参考:【Docker】安装registry本地镜像库,开启Https功能-CSDN博客

  修改harbor.yml配置文件:

# https related config
https:
  # https port for harbor, default is 443
  port: 444
  # The path of cert and key files for nginx  cert.crt and key.key
  certificate: /root/dockerregistry/pki/registry.crt  [你主机上存放的证书]
  private_key: /root/dockerregistry/pki/registry_private.key  [这个证书对应的私钥]




# Uncomment uaa for trusting the certificate of uaa instance that is hosted via self-signed cert.
uaa:
   ca_file: /root/dockerregistry/pki/registry.crt [你主机上存放的证书] 

删除把之前的data_volume中的数据全部删除,然后

./prepare

./install.sh 

就可以了

推送镜像

1、创建用户

2、创建项目

3、项目添加用户成员

4、推送镜像

    (a) 把harbor的签名证书放到docker的配置目录:

              /etc/docker/certs.d/12.34.34.45[ip]:444[端口]/ca.crt

      (b) 推送镜像

         docker push  12.34.34.45:444/base/pause:9   

          记得base是刚才创建的一个名称,这个路径要加上,不然推送不了。 然后用base这个项目的关联用户登录下docker ,就可以推送了   docker login  12.34.34.45:444   -u xxxxx -p  xxxxx

Harbor核心组件解释

Harbor在架构上主要由6个组件构成:

Proxy:Harbor的registry, UI, token等服务,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: 负责储存Docker镜像,并处理docker push/pull 命令。由于我们要对用户进行访问控制,即不同用户对Docker image有不同的读写权限,Registry会指向一个token服务,强制用户的每次docker pull/push请求都要携带一个合法的token, Registry会通过公钥对token 进行解密验证。

Core services: 这是Harbor的核心功能,主要提供以下服务:

UI:提供图形化界面,帮助用户管理registry上的镜像(image), 并对用户进行授权。

webhook:为了及时获取registry 上image状态变化的情况, 在Registry上配置webhook,把状态变化传递给UI模块。

token 服务:负责根据用户权限给每个docker push/pull命令签发token. Docker 客户端向Regiøstry服务发起的请求,如果不包含token,会被重定向到这里,获得token后再重新向Registry进行请求。

Database:为core services提供数据库服务,负责储存用户权限、审计日志、Docker image分组信息等数据。

Job Services:提供镜像远程复制功能,可以把本地镜像同步到其他Harbor实例中。

Log collector:为了帮助监控Harbor运行,负责收集其他组件的log,供日后进行分析。

各个组件之间的关系如下图所示:

三、Harbor特性

基于角色的访问控制 :用户与Docker镜像仓库通过“项目”进行组织管理,一个用户可以对多个镜像仓库在同一命名空间(project)里有不同的权限。

镜像复制 : 镜像可以在多个Registry实例中复制(同步)。尤其适合于负载均衡,高可用,混合云和多云的场景。

图形化用户界面 : 用户可以通过浏览器来浏览,检索当前Docker镜像仓库,管理项目和命名空间。

AD/LDAP 支持 : Harbor可以集成企业内部已有的AD/LDAP,用于鉴权认证管理。

审计管理 : 所有针对镜像仓库的操作都可以被记录追溯,用于审计管理。

国际化 : 已拥有英文、中文、德文、日文和俄文的本地化版本。更多的语言将会添加进来。

RESTful API : RESTful API 提供给管理员对于Harbor更多的操控, 使得与其它管理软件集成变得更容易。

部署简单 : 提供在线和离线两种安装工具, 也可以安装到vSphere平台(OVA方式)虚拟设备。

四、Harbor和Registry的比较

Harbor和Registry都是Docker的镜像仓库,但是Harbor作为更多企业的选择,是因为相比较于Regisrty来说,它具有很多的优势。

1.提供分层传输机制,优化网络传输

Docker镜像是是分层的,而如果每次传输都使用全量文件(所以用FTP的方式并不适合),显然不经济。必须提供识别分层传输的机制,以层的UUID为标识,确定传输的对象。

2.提供WEB界面,优化用户体验

只用镜像的名字来进行上传下载显然很不方便,需要有一个用户界面可以支持登陆、搜索功能,包括区分公有、私有镜像。

3.支持水平扩展集群

当有用户对镜像的上传下载操作集中在某服务器,需要对相应的访问压力作分解。

4.良好的安全机制

企业中的开发团队有很多不同的职位,对于不同的职位人员,分配不同的权限,具有更好的安全性。

5.Harbor提供了基于角色的访问控制机制,并通过项目来对镜像进行组织和访问权限的控制。kubernetes中通过namespace来对资源进行隔离,在企业级应用场景中,通过将两者进行结合可以有效将kubernetes使用的镜像资源进行管理和访问控制,增强镜像使用的安全性。尤其是在多租户场景下,可以通过租户、namespace和项目相结合的方式来实现对多租户镜像资源的管理和访问控制。
