Harbor 安裝條件

官網給出了安裝需要的最低硬體和軟體的條件：https://goharbor.io/docs/2.0.0/install-config/installation-prereqs/

最低硬體要求：

最低軟體要求：

Harbor 要求在目標主機上開啟以下埠：

線上安裝和離線安裝

可以從 官方釋出頁面下載 Harbor 安裝程式。下載線上安裝程式或離線安裝程式。

• 線上安裝程式：線上安裝程式從 Docker 中心下載 Harbor 映象。因此，安裝程式的尺寸非常小。
• 離線安裝程式：如果要部署 Harbor 的主機沒有連線到 Internet，請使用離線安裝程式。離線安裝程式包含預先構建的映像，因此它比線上安裝程式大

線上和離線安裝程式的安裝過程幾乎相同。

這裡我主要使用離線安裝，因為線上安裝因為牆、內部網路等原因，有的同學會下載很慢，而離線安裝包都包含了預先構建的映象，所以直接現在離線安裝包最好！

離線安裝

到 官方釋出 頁面下載離線安裝包：

下載後將壓縮包上傳到伺服器使用命令tar -zxf harbor-offline-installer-v2.4.2.tgz解壓，解壓後如下圖：

解壓後在當前的解壓路徑可以得到資料夾harbor，cd harbor 進資料夾：

可以看到資料夾有一堆檔案，其中最主要的是 harbor.yml.tmpl和 install.sh ，他們分別是組態檔和安裝執行檔案。

# 複製並重新命名一份新的組態檔
cp harbor.yml.tmpl harbor.yml
# 使用 vim 編輯組態檔，如果提示找不到vim ，使用以下命令安裝 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 編輯

開啟harbor.yml，最主要是更改一下幾點，其他的保持預設即可：

harbor.yml範例模板：

# 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

    # 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

編輯完成後按ESC，然後使用命令:wq儲存並推出。

然後繼續用命令執行安裝./install.sh。

安裝過程（從別人部落格上扒下來的圖）：

當出現紅箭頭指向的提示的時候，就表示安裝成功了！

然後根據在harbor.yml檔案中設定的埠與IP地址(或域名)進行存取

現在Harbor已經可以使用了！

由於我部署的時候沒有使用HTTPS，所以使用docker登入的時候會出現一下異常資訊（還是借的別人的圖）：

原因：Docker自從1.3.X之後docker registry互動預設使用的是HTTPS，但是搭建私有映象預設使用的是HTTP服務，所以與私有映象交時出現以上錯誤。

解決辦法：

找到docker 的 daemon.json 組態檔，CentOS 7 的路徑：/etc/docker/daemon.json（系統版本不同所處位置不同，其他版本的請自行百度），如果路徑下沒有這個檔案自己建立即可。然後再組態檔里加上：

{
  // docker 映象下載地址
  "registry-mirrors": ["https://mirror.ccs.tencentyun.com"],
   // 不安全的映象倉庫（此處設定Harbor 的地址+埠號）
   "insecure-registries": ["192.168.0.2:8088"],
}

操作完後讓這個檔案生效：

a.修改完成後reload組態檔
sudo systemctl daemon-reload
 
b.重啟docker服務
sudo systemctl restart docker.service
