Harbor-私有镜像仓库的安装部署

Harbor 安装条件

官网给出了安装需要的最低硬件和软件的条件:https://goharbor.io/docs/2.0.0/install-config/installation-prereqs/

最低硬件要求:

资源 最低限度 推荐的
CPU 2核 4 核
内存 4GB 8 GB
磁盘 40 GB 160 GB

最低软件要求:

软件 版本 描述
Docker engine 版本 17.06.0-ce+ 或更高版本 有关安装说明,请参阅 Docker 引擎文档
Docker Compose 版本 1.18.0 或更高版本 有关安装说明,请参阅 Docker Compose 文档
OpenSSL 最新的优先 用于为 Harbor 生成证书和密钥

Harbor 要求在目标主机上打开以下端口:

端口号 协议 描述
443 HTTPS Harbor 门户和核心 API 接受此端口上的 HTTPS 请求。您可以在配置文件中更改此端口。
4443 HTTPS 与 Harbor 的 Docker 内容信任服务的连接。仅在启用 Notary 时才需要。您可以在配置文件中更改此端口。
80 HTTP Harbor 门户和核心 API 接受此端口上的 HTTP 请求。您可以在配置文件中更改此端口。

在线安装和离线安装

可以从 官方发布页面下载 Harbor 安装程序。下载在线安装程序或离线安装程序。

  • 在线安装程序:在线安装程序从 Docker 中心下载 Harbor 镜像。因此,安装程序的尺寸非常小。
  • 离线安装程序:如果要部署 Harbor 的主机没有连接到 Internet,请使用离线安装程序。离线安装程序包含预先构建的映像,因此它比在线安装程序大

在线和离线安装程序的安装过程几乎相同。

这里我主要使用离线安装,因为在线安装因为墙、内部网络等原因,有的同学会下载很慢,而离线安装包都包含了预先构建的镜像,所以直接现在离线安装包最好!

离线安装

官方发布 页面下载离线安装包:

image-20220321223547469

下载后将压缩包上传到服务器使用命令tar -zxf harbor-offline-installer-v2.4.2.tgz解压,解压后如下图:

image-20220322223019699

解压后在当前的解压路径可以得到文件夹harborcd harbor 进文件夹:

image-20220322223137274

可以看到文件夹有一堆文件,其中最主要的是 harbor.yml.tmplinstall.sh ,他们分别是配置文件和安装执行文件。

# 复制并重命名一份新的配置文件
cp harbor.yml.tmpl harbor.yml
# 使用 vim 编辑配置文件,如果提示找不到vim ,使用以下命令安装 vim
# ubuntu 使用 sudo apt-get install vim 
# redHat/Fedora/CentOS 使用 yum install vim 
vim harbor.yml  # 或者使用 vi harbor.yml 编辑

打开harbor.yml,最主要是更改一下几点,其他的保持默认即可:

harbor.yml示例模板:

# 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.
hostname: 192.168.0.2

# http related config
http:
  # port for http, default is 80. If https enabled, this port will redirect to https port
  port: 8088

# 不使用HTTPS 
# https related config
# https:
  # https port for harbor, default is 443
  # port: 443
  # The path of cert and key files for nginx
  # certificate: /your/certificate/path
  # private_key: /your/private/key/path

# # Uncomment following will enable tls communication between all harbor components
# internal_tls:
#   # set enabled to true means internal tls is enabled
#   enabled: true
#   # put your cert and key files on dir
#   dir: /etc/harbor/tls/internal

# Uncomment external_url if you want to enable external proxy
# And when it enabled the hostname will no longer used
# external_url: https://reg.mydomain.com:8433

# The initial password of Harbor admin
# It only works in first time to install harbor
# Remember Change the admin password from UI after launching Harbor.
harbor_admin_password: Harbor12345

# Harbor DB configuration
database:
  # The password for the root user of Harbor DB. Change this before any production use.
  password: root123
  # The maximum number of connections in the idle connection pool. If it <=0, no idle connections are retained.
  max_idle_conns: 100
  # The maximum number of open connections to the database. If it <= 0, then there is no limit on the number of open connections.
  # Note: the default number of connections is 1024 for postgres of harbor.
  max_open_conns: 900

# The default data volume
data_volume: /mnt/harbor/data

# Harbor Storage settings by default is using /data dir on local filesystem
# Uncomment storage_service setting If you want to using external storage
# storage_service:
#   # ca_bundle is the path to the custom root ca certificate, which will be injected into the truststore
#   # of registry's and chart repository's containers.  This is usually needed when the user hosts a internal storage with self signed certificate.
#   ca_bundle:

#   # storage backend, default is filesystem, options include filesystem, azure, gcs, s3, swift and oss
#   # for more info about this configuration please refer https://docs.docker.com/registry/configuration/
#   filesystem:
#     maxthreads: 100
#   # set disable to true when you want to disable registry redirect
#   redirect:
#     disabled: false

# 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
  #
  # 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://developer.github.com/v3/#rate-limiting
  #
  # You can create a GitHub token by following the instructions in
  # https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line
  #
  # github_token: xxx

    # Log files are rotated only if they grow bigger than log_rotate_size bytes. If size is followed by k, the size is assumed to be in kilobytes.
    # If the M is used, the size is in megabytes, and if G is used, the size is in gigabytes. So size 100, size 100k, size 100M and size 100G
    # are all valid.

  dryrun: false

编辑完成后按ESC,然后使用命令:wq保存并推出。

然后继续用命令执行安装./install.sh

安装过程(从别人博客上扒下来的图):

当出现红箭头指向的提示的时候,就表示安装成功了!

然后根据在harbor.yml文件中配置的端口与IP地址(或域名)进行访问

现在Harbor已经可以使用了!

由于我部署的时候没有使用HTTPS,所以使用docker登录的时候会出现一下异常信息(还是借的别人的图):

原因:Docker自从1.3.X之后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,所以与私有镜像交时出现以上错误。

解决办法:

找到docker 的 daemon.json 配置文件,CentOS 7 的路径:/etc/docker/daemon.json(系统版本不同所处位置不同,其他版本的请自行百度),如果路径下没有这个文件自己创建即可。然后再配置文件里加上:

{
  // docker 镜像下载地址
  "registry-mirrors": ["https://mirror.ccs.tencentyun.com"],
   // 不安全的镜像仓库(此处配置Harbor 的地址+端口号)
   "insecure-registries": ["192.168.0.2:8088"],
}

操作完后让这个文件生效:

a.修改完成后reload配置文件
sudo systemctl daemon-reload
 
b.重启docker服务
sudo systemctl restart docker.service

本次的Harbor安装教程就到此为止了,如需了解Harbor的更多详情信息请移步其他博客!
