Django example

[williamhbell]

The https://github.com/docker/awesome-compose/blob/master/official-documentation-samples/django/README.md example instructions fail with

docker compose run web django-admin startproject composeexample .
...
  File "/usr/local/lib/python3.13/site-packages/django/core/management/commands/startproject.py", line 2, in <module>
    from django.core.management.templates import TemplateCommand
  File "/usr/local/lib/python3.13/site-packages/django/core/management/templates.py", line 1, in <module>
    import cgi
ModuleNotFoundError: No module named 'cgi'

The cgi module was removed from Python, such that django crashes when used with the latest official Python Docker image. The Dockerfile base image should be specified to avoid this issue. For example:

# syntax=docker/dockerfile:1
FROM python:3.11
ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

works as expected.
