README for docker Deployment

Welcome to the new docker directory for deploying Dify using Docker Compose. This README outlines the updates, deployment instructions, and migration details for existing users.

What’s Updated

• Persistent Environment Variables: Environment variables are now managed through a .env file, ensuring that your configurations persist across deployments.
• Unified Vector Database Services: All vector database services are now managed from a single Docker Compose file docker-compose.yaml. You can switch between different vector databases by setting the VECTOR_STORE environment variable in your .env file.
• Mandatory .env File: A .env file is now required to run docker compose up. This file is crucial for configuring your deployment and for any custom settings to persist through upgrades.
• Legacy Support: Previous deployment files are now located in the docker-legacy directory and will no longer be maintained.

How to Deploy Dify with docker-compose.yaml

1. Prerequisites: Ensure Docker and Docker Compose are installed on your system.
2. Environment Setup:
   • Navigate to the docker directory.
   • Copy the .env.example file to a new file named .env by running cp .env.example .env.
   • Customize the .env file as needed. Refer to the .env.example file for detailed configuration options.
3. Running the Services:
   • Execute docker compose up from the docker directory to start the services.
   • To specify a vector database, set the VECTOR_store variable in your .env file to your desired vector database service, such as milvus, weaviate, or opensearch.

How to Deploy Middleware for Developing Dify

1. Middleware Setup:
   • Use the docker-compose.middleware.yaml for setting up essential middleware services like databases and caches.
   • Navigate to the docker directory.
   • Ensure the middleware.env file is created by running cp middleware.env.example middleware.env (refer to the middleware.env.example file).
2. Running Middleware Services:
   • Execute docker-compose -f docker-compose.middleware.yaml up -d to start the middleware services.

Migration for Existing Users

For users migrating from the docker-legacy setup:

1. Review Changes: Familiarize yourself with the new .env configuration and Docker Compose setup.
2. Transfer Customizations:
   • If you have customized configurations such as docker-compose.yaml, ssrf_proxy/squid.conf, or nginx/conf.d/default.conf, you will need to reflect these changes in the .env file you create.
3. Data Migration:
   • Ensure that data from services like databases and caches is backed up and migrated appropriately to the new structure if necessary.

Additional Information

• Continuous Improvement Phase: We are actively seeking feedback from the community to refine and enhance the deployment process. As more users adopt this new method, we will continue to make improvements based on your experiences and suggestions.
• Support: For detailed configuration options and environment variable settings, refer to the .env.example file and the Docker Compose configuration files in the docker directory.

This README aims to guide you through the deployment process using the new Docker Compose setup. For any issues or further assistance, please refer to the official documentation or contact support.
