Review Summary
Your solution is approved. All five required files are present and correctly implement the Docker setup for the DRF Cinema project: the .dockerignore properly excludes unnecessary files, the Dockerfile uses the slim base image with a non-root user for security, the docker-compose.yml orchestrates both the app and db services with proper volumes and startup commands including wait_for_db, the database readiness command handles connection retries correctly, and the settings.py configures PostgreSQL via environment variables. A couple of minor improvements you could consider for future submissions: setting ALLOWED_HOSTS to include localhost or ['*'] would allow testing requests to the container at 127.0.0.1:8000, and providing an .env.example file would help users know which environment variables are required for the database configuration.

The docker-compose.yml file is missing entirely. This file is required to: define both app and db services, configure the wait_for_db command in the startup sequence, manage volumes for static/media files, and link the services together.
