Docker in 60 Seconds: A Quick Guide to Containerization

Docker in under 60 seconds gives you a no-fluff introduction to containerization. Learn why Docker solves the "it works on my machine" problem and the core idea behind containers: package your app and its dependencies once, then run it anywhere without setup hassles. Understand the basic flow from Dockerfile to image to container, and see how Docker keeps development, testing, and production environments consistent, lightweight, and fast. This micro-explanation provides a solid mental model for beginners, DevOps newcomers, or anyone curious about modern deployment tools.
