What I love about Django is that you can create a Django project with just one file.

You can turn a fresh Debian machine into a running Django web app by just doing:

    apt install -y python3-django apache2 libapache2-mod-wsgi-py3

And then creating the one file Django needs:

/var/www/mysite/mysite/wsgi.py:

    import os
    import django
    from django.core.wsgi import get_wsgi_application
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.wsgi')
    application = get_wsgi_application()

    ROOT_URLCONF = 'mysite.wsgi'
    SECRET_KEY = 'hello'

    def index(request):
        return django.http.HttpResponse('This is the homepage')

    def cats(request):
        return django.http.HttpResponse('This is the cats page')

    urlpatterns = [
        django.urls.path('', index),
        django.urls.path('cats', cats),
    ]

And then telling Apache where to look for it:

/etc/apache2/sites-enabled/000-default.conf:

    ServerName 127.0.0.1
    WSGIPythonPath /var/www/mysite
    <VirtualHost *:80>
        WSGIScriptAlias / /var/www/mysite/mysite/wsgi.py
        <Directory /var/www/mysite/mysite>
            <Files wsgi.py>
                Require all granted
            </Files>
        </Directory>
    </VirtualHost>

And voilá, you have a running Django application, which you can expand upon to any size and complexity.

If you want to try it in a docker container, you can run

    docker run -it --rm -p80:80 debian:12

perform the steps above and then access the Django application at 127.0.0.1
