Whether I set.env in the api directory or the docker directory, the configuration does not take effect

docker compose down docker compose up -d

To ensure that the environment variables are correctly set and applied in your Docker setup for the dify repository, follow these steps:

1. Clone the Dify Repository:

   git clone https://github.com/langgenius/dify.git
   

2. Navigate to the Docker Directory:

   cd dify/docker
   

3. Copy the Example Environment File:

   cp .env.example .env
   

4. Edit the .env File: Open the .env file in a text editor and customize the environment variable values as needed. Refer to the .env.example file for detailed configuration options.

5. Start Dify with Docker Compose:

   docker compose up -d
   

6. Restart Dify After Editing Environment Variables: If you make any changes to the .env file, restart Dify to apply the changes:

   docker compose down
   docker compose up -d
   

Additional Tips:

• Persistent Environment Variables: The .env file ensures that your configurations persist across deployments.
• Vector Database Configuration: You can switch between different vector databases by setting the VECTOR_STORE environment variable in your .env file to your desired service, such as milvus, weaviate, or opensearch.
• Middleware Services: For setting up essential middleware services like databases and caches, use the docker-compose.middleware.yaml file and ensure the middleware.env file is created by running cp middleware.env.example middleware.env.

The full set of annotated environment variables can be found in the docker/.env.example file. Make sure to review and set these variables according to your requirements. For more detailed instructions, refer to the docker/README.md file in the repository ^[1][2][3][4].

Specific Instructions for the api Directory:

For the api directory, ensure you have set the environment variables in the .env file located in the api directory. Here are some key configurations:

1. SECRET_KEY: Generate a strong key using openssl rand -base64 42 and set it in the SECRET_KEY environment variable.
2. API URLs: Set the base URLs for various services.
3. Celery and Redis Configuration: Set the CELERY_BROKER_URL and other Redis-related variables.
4. Database Configuration: Set the PostgreSQL database connection details.
5. Storage Configuration: Configure the storage type and related settings.
6. CORS Configuration: Set allowed origins for CORS.
7. Vector Database Configuration: Configure the vector database and its connection details.
8. Upload Configuration: Set limits for file uploads.
9. Mail Configuration: Configure the mail service.
10. Sentry Configuration: Set the Sentry DSN.
11. Debugging and Logging: Configure debugging and logging settings.
12. Notion Import Configuration: Set Notion integration details.
13. ETL and SSRF Proxy Configuration: Configure ETL and SSRF proxy settings.
14. Batch Upload and Keyword Data Source Configuration: Set limits for batch uploads and keyword data sources.
15. Code Execution Configuration: Set limits for code execution.
16. API Tool and HTTP Node Configuration: Configure API tool and HTTP node settings.
17. Indexing Configuration: Set the maximum segmentation tokens length.
18. Workflow Runtime Configuration: Configure workflow execution limits.
19. App Configuration: Set the maximum execution time for the app.

These configurations should be set in the .env file in the api directory based on your deployment requirements ^[5][6].

After setting the environment variables, restart the Docker containers to apply the changes:

docker compose down
docker compose up -d

我的问题任然没有解决！我就是按照这个方式去做的，但是没有生效的，我的截图已经说明情况了！

Your image doesn't give any useful information, the API environment variables you modify won't work for Docker, and if you follow the documentation, your environment variables won't have just 4 lines. And you didn't say what you were going to do with the environment variables

Environment variables As I understand it, the ones that are not set will use the default value, right? I just want to set the maximum workflow execution time to 1 hour instead of the current 20 minutes, and it doesn't actually work whether I set the .env file in docker or the .env file in api
