Docker flow for Car Rental System
=================================

Prerequisites
-------------
1. Install Docker Desktop.
2. Start Docker Desktop.
3. Run all commands from the project root:
   C:\Python Pycharm\Car-Rental-System


Build and start the full project
--------------------------------
docker compose up --build

Open the application:
http://localhost:8000/

Open Django admin:
http://localhost:8000/admin/


Run in background
-----------------
docker compose up --build -d

View logs:
docker compose logs -f

View only Django logs:
docker compose logs -f web

View only Celery worker logs:
docker compose logs -f celery

View only Celery beat logs:
docker compose logs -f celery-beat


Database and Django commands
----------------------------
Run migrations manually:
docker compose exec web python manage.py migrate

Create an admin user:
docker compose exec web python manage.py createsuperuser

Collect static files:
docker compose exec web python manage.py collectstatic --noinput

Open Django shell:
docker compose exec web python manage.py shell

Run tests:
docker compose exec web python manage.py test


Service commands
----------------
Start containers:
docker compose start

Stop containers:
docker compose stop

Restart containers:
docker compose restart

Stop and remove containers, keeping database/media volumes:
docker compose down

Stop and remove containers plus database/media/cache volumes:
docker compose down -v


Rebuild after dependency or Dockerfile changes
----------------------------------------------
docker compose build --no-cache
docker compose up


Useful container access
-----------------------
Open a shell inside the Django container:
docker compose exec web sh

Open PostgreSQL shell:
docker compose exec db psql -U postgres -d car_rental_db

Open Redis CLI:
docker compose exec redis redis-cli


Project services in Docker
--------------------------
web          Django application on http://localhost:8000
db           PostgreSQL database on localhost:5432
redis        Redis cache and Celery broker on localhost:6379
celery       Celery background worker
celery-beat  Celery scheduled task runner


Notes
-----
The web container automatically runs:
python manage.py migrate --noinput
python manage.py collectstatic --noinput

The Docker Compose file reads .env, but overrides DB_HOST and Redis URLs inside Docker so containers can communicate with each other.
