Add Docker Volume for Database Persistence

[arcane-engine[bot]]

This update enhances the docker-compose.yml file by adding a volume for the database, ensuring data persistence even when containers are stopped or removed. The database data is now stored in a Docker volume named db_data, improving data reliability and management.

Docker Configuration

• Updated docker-compose.yml to include a volume for the database.
• Added a new volume db_data to persist database data at /var/lib/postgresql/data.

These changes ensure that the database data is not lost, enhancing the robustness of the application's data management.

File Modified

• docker-compose.yml
