Docker Tutorial for Beginners: From Absolute Basics to Hands-on Project

This comprehensive Docker tutorial is your ultimate guide to understanding and using Docker, from the fundamental concepts to a practical, hands-on project. We start by setting the context, explaining what Docker is and its real-world relevance. You'll learn about containerization, the key differences between VMs and containers, and why Docker is essential for solving issues like environment mismatch and bridging the gap between development and production.
We'll then dive deep into the Docker architecture, including the Docker Engine, CLI, Daemon, images, containers, and volumes. You'll discover how Docker is used in real-life scenarios such as microservices, CI/CD pipelines, and ML pipelines.
This video breaks down complex topics like Docker images, with their layered filesystem, and Dockerfiles, including key instructions like FROM, RUN, and CMD. We'll explore the full Docker lifecycle, from pulling images from Docker Hub to building, running, stopping, and pushing them. You'll also learn essential lifecycle management tasks like volume management and cleaning up resources.
The tutorial culminates in a hands-on section where you'll set up and install Docker Desktop, pull a Python image from Docker Hub, and, most importantly, dockerize a Streamlit application from scratch. By the end, you'll have a solid foundation in Docker and practical experience to start using it in your own projects.
