This commit introduces changes to ensure that Alembic database migrations
are automatically applied when the backend Docker container starts.
Key changes:
- Added `be/entrypoint.sh`: This script first runs `alembic upgrade head`
to apply any pending migrations and then executes the main container
command (e.g., starting Uvicorn).
- Modified `be/Dockerfile`:
- The `entrypoint.sh` script is copied into the image and made executable.
- The Docker `ENTRYPOINT` is set to this script, ensuring migrations
run before the application starts.
- Updated `docker-compose.yml`:
- The `DATABASE_URL` for the `backend` service has been set to the
Neon database URL you provided.
- Verified `be/alembic/env.py`: Confirmed that it correctly sources the
`DATABASE_URL` from environment variables for Alembic to use.
These changes address the issue where migrations were not being run,
preventing the application from starting correctly.
