The Complete Practical Docker Guide - Cleaning Up My Docker Setup

This video tutorial covers the process of cleaning up Docker containers and images. It begins with listing stopped containers and using the 'docker container prune' command to remove them. The tutorial then explains how to list Docker images and use the 'docker image prune' command to remove unused images, including the difference between unused and dangling images. The video also discusses the structure of Docker images, focusing on file system layers and how they are removed during cleanup. Finally, the tutorial concludes with a brief introduction to the next lecture, which will cover running a simple 'hello world' container.
