Common Mistakes

Choosing a Node.js or Nginx image which are not for Python apps.

💡 Hint

Common Mistakes

Exposing port 8080 which is not Django's default.

Setting working directory to a path not used in the Dockerfile.

Django's default development server runs on port 8000, and setting WORKDIR /app sets the working directory inside the container.

💡 Hint

Common Mistakes

Using 'runserver' as the first argument instead of 'python'.

Using port 8080 instead of 8000.

Omitting 'manage.py' which is required to run Django commands.

The command runs python manage.py runserver 0.0.0.0:8000 to start the Django server accessible from outside the container.
