Production Servers (Gunicorn & Nginx)

🐍 FlaskLesson 15Advanced

Flask's built-in development server is not suited for production. You must configure WSGI application gateway servers like Gunicorn or uWSGI to coordinate requests.

1 Production Stack Configuration

The standard industry pipeline forces Nginx to capture internet requests, forwarding connections down to local Gunicorn processes executing Flask script files:

Shell — Running Gunicorn

# Install Gunicorn server
pip install gunicorn

# Run Gunicorn binding the app entry point
gunicorn -w 4 -b 127.0.0.1:8000 app:app

2 Code Challenge

Challenge: Write a custom Dockerfile that configures a production Python workspace, installs dependencies, and runs Gunicorn to launch your Flask application securely.
