 1. **Running Middleware Services**:
    - Navigate to the `docker` directory.
-   - Execute `docker compose -f docker-compose.middleware.yaml --profile weaviate -p dify up -d` to start the middleware services. (Change the profile to other vector database if you are not using weaviate)

+> Compose automatically loads `COMPOSE_PROFILES=${DB_TYPE:-postgresql},weaviate` from `middleware.env`, so no extra `--profile` flags are needed. Adjust variables in `middleware.env` if you want a different combination of services.
