12-12: Minor: Comment clarity.The comment change from "Install app dependencies" to "Install dependencies" is acceptable but slightly less specific. Consider keeping the original phrasing or being more explicit (e.g., "# Install Python dependencies from requirements.txt").

6-20: Verify whether database migrations should run before server startup.The Dockerfile installs
mysqlclientand pulls requirements fromrequirements.txt, but no migrations are run before the server starts via CMD. If database schema is required for the app to function, migrations should be executed during container initialization.Consider using an entrypoint script that runs migrations before starting the server, or document that migrations must be run manually before container startup.

Production-unsafe: Django development server should not be used in containerized/production environments.
The runserver command is Django's development server and has significant security, performance, and stability limitations. It should only be used during local development and never in production, staging, or any other non-local environment.
For containerized deployments, use a production WSGI application server such as:
- Gunicorn (most common)
- uWSGI
- Waitress
- Daphne (for async apps)
Recommended fix using Gunicorn:
First, add gunicorn to requirements.txt, then update the CMD:
-CMD ["python3", "manage.py", "runserver", "0.0.0.0:8000"]
+CMD ["gunicorn", "your_project_name.wsgi:application", "--bind", "0.0.0.0:8000", "--workers", "4"]Replace your_project_name with your actual Django project name.
Committable suggestion skipped: line range outside the PR's diff.

In Dockerfile around line 20, the image currently uses Django's development
server via CMD ["python3", "manage.py", "runserver", "0.0.0.0:8000"], which is
unsafe for production; switch to a production WSGI server by adding gunicorn to
requirements.txt and replacing the CMD to run gunicorn for your Django project
(use your Django project module name, bind to 0.0.0.0:8000, set a sensible
worker count and timeout, and optionally set --chdir to the project directory).
Ensure the Dockerfile exposes the port and that the ENTRYPOINT/CMD runs gunicorn
with the correct module path (e.g., your_project_name.wsgi:application),
worker/options configured for the container, and that gunicorn is installed in
the image.
