Setup Dockerized Django Cinema Project with Env and Fixtures

[3883IZ]

This PR completes the setup of the Django Cinema project with Docker and environment configuration.

Key changes:

• Added Dockerfile and docker-compose.yml for production-ready deployment with Gunicorn.
• Configured .env.local, .env.docker, and .env.example for secure environment variable management.
• Updated settings.py to load configuration from environment variables.
• Added requirements.txt with Gunicorn and verified dependencies.
• Applied migrations and ensured database connectivity.
• Implemented automatic superuser creation via .env.docker.
• Created fixtures for initial data: genres, actors, cinema halls, movies, and movie sessions.
• Updated .gitignore to exclude sensitive files and environment-specific artifacts.
• Verified admin panel access with screenshots.

This PR ensures repository hygiene, reproducible deployment, and a clear starting dataset for testing the cinema booking workflow.

Review Summary

Great job getting the application dockerized and running! The services start up correctly, and the wait_for_db command is a solid implementation.

However, some changes are needed before this can be approved. The main issue is in your docker-compose.yml file. Using the bind mount volumes: - .:/app makes the container dependent on your local files, which goes against the core requirement of creating a fully independent service. This mount overrides the code you copied into the image with your Dockerfile, making your .dockerignore ineffective at runtime. Please remove this line to ensure the container uses the code built into the image.

Additionally, for a more robust and secure image, I recommend adding entries like .env* and media/ to your .dockerignore file. Also, the CMD in your Dockerfile has an incorrect path to the WSGI application; it should be cinema_service.wsgi:application.

This file is missing some important entries. To keep the image secure and lightweight, you should also ignore:

• Environment files (.env*): These may contain secrets and shouldn't be copied into the image.
• IDE folders (.idea/, .vscode/): These are not needed for the application to run.
• The media/ directory: Since this is handled by a volume, it shouldn't be part of the initial image build.

The path to the WSGI application appears to be incorrect. Based on the project structure shown in cinema_service/settings.py and the command in your docker-compose.yml, it should likely be cinema_service.wsgi:application instead of cinema.wsgi:application.

Using a bind mount .:/app for the application code is convenient for development but introduces issues. It mounts your entire project directory from the host into the container, which overrides all the files you added with COPY . . in your Dockerfile. This makes your .dockerignore file ineffective at runtime, as ignored files (like .git/ or .env files) will still be present inside the container. For a cleaner, more production-like setup, it's better to rely on the code that was built into the image.

Review Summary

Excellent work on this iteration! I am approving your solution. You've successfully addressed all the feedback from the previous review, resulting in a robust and well-structured Docker setup. The application is now fully independent of the local environment, and you've implemented best practices for managing services, data persistence, and the image build process. The project now meets all the specified requirements. Great job!
