5.3. 使用 API 自动化 Red Hat Quay 进程

流程

1. 创建执行 API 命令的 Python 脚本。以下示例使用 DELETE /api/v1/organization/{orgname}/applications/{client_id} API 端点删除机构应用程序。

   example.py 文件

   import requests 

   1

   
   
   # Hard-coded values
   API_BASE_URL = "http://<quay-server.example.com>/api/v1" 

   2

   
   ACCESS_TOKEN = "<access_token>" 

   3

   
   ORG_NAME = "<organization_name>" 

   4

   
   
   def get_all_organization_applications():
       url = f"{API_BASE_URL}/organization/{ORG_NAME}/applications"
       headers = {
           "Authorization": f"Bearer {ACCESS_TOKEN}"
       }
   
       response = requests.get(url, headers=headers)
   
       if response.status_code == 200:
           try:
               applications = response.json()
               # Print the raw response for debugging
               print("Raw response:", applications)
   
               # Adjust parsing logic based on the response structure
               if isinstance(applications, dict) and 'applications' in applications:
                   applications = applications['applications']
   
               if isinstance(applications, list):
                   print("Organization applications retrieved successfully:")
                   for app in applications:
                       # Updated key from 'title' to 'name'
                       print(f"Name: {app['name']}, Client ID: {app['client_id']}")
                   return applications
               else:
                   print("Unexpected response format.")
                   return []
           except requests.exceptions.JSONDecodeError:
               print("Error decoding JSON response:", response.text)
               return []
       else:
           print(f"Failed to retrieve applications. Status code: {response.status_code}, Response: {response.text}")
           return []
   
   def delete_organization_application(client_id):
       url = f"{API_BASE_URL}/organization/{ORG_NAME}/applications/{client_id}"
       headers = {
           "Authorization": f"Bearer {ACCESS_TOKEN}"
       }
   
       response = requests.delete(url, headers=headers)
   
       if response.status_code == 204:
           print(f"Application {client_id} deleted successfully.")
       else:
           print(f"Failed to delete application {client_id}. Status code: {response.status_code}, Response: {response.text}")
   
   def main():
       applications = get_all_organization_applications()
       for app in applications:
           if app['name'] != "<admin_token_app>": <5>  # Skip the "admin-token-app"
               delete_organization_application(app['client_id'])
           else:
               print(f"Skipping deletion of application: {app['name']}")
   
   # Execute the main function
   main()

   1

   在 Python 代码中包括 导入 库。

   2

   附加了 /api/v1 的 registry 的 URL。

   3

   您的 OAuth 2 访问令牌。

   4

   保存应用程序的组织。

   要保留的应用程序令牌的名称。

2. 将脚本保存为 prune_applications.py。

3. 创建自动运行脚本的 cron 作业：

   1. 运行以下命令打开 crontab 编辑器：

      $ crontab -e

   2. 在编辑器中，添加用于运行脚本的 cron 作业。以下示例按每月运行一次脚本：

      0 0 1 * * sudo python /path/to/prune_images.py >> /var/log/prune_images.log 2>&1
