Welcome to Lesson 5.9 of the Django DevOps Mastery Series!
In this important lesson, you’ll learn how to clean up unused Docker resources like containers, images, volumes, and networks that may be cluttering your system and consuming unnecessary disk space.

As you build and rebuild containers during development, Docker stores everything unless you tell it to clean up. This guide will help you stay organized, save space, and optimize performance.

Keeps your Docker environment lean and fast

Important step before pushing to CI/CD pipelines or Docker Hub

👨‍🏫 Perfect For:
Django developers working with Docker
