Docker For Beginners

Docker changed how software gets built, shipped, and run by packaging an application and everything it needs into one portable unit — a container. This course takes a complete beginner from first principles through the daily-driver Docker workflow, in the order you actually need it: run and manage containers, build your own images, connect and persist them with networking and storage, configure them at runtime, compose them into multi-container apps, and close with container security basics and where to go next. Every module pairs short concept lessons with terminal-first labs, and the course ends with a capstone that mirrors a real task: containerize a small web app, wire it to a database with Compose, and push the image to Docker Hub.
