Docker and Container Fundamentals for Beginners

Modern software development requires applications to run reliably across different environments, from a local developer machine to production servers. Docker solves the classic "it works on my machine" problem by packaging software into lightweight, isolated containers. This text-based course guides you from containerization novice to confidently managing containerized applications. You will learn how to create your own container images, manage networking and storage, and orchestrate multi-container setups. What you will learn: Understand core containerization concepts and how Docker differs from traditional virtual machines; Build custom container images using efficient, multi-stage Dockerfiles; Manage container storage with volumes and configure container networking for secure communication; Run and coordinate multi-container applications using Docker Compose; Apply modern container security practices and keep your images lightweight. The course begins with foundational terminology and core architecture before moving into hands-on image creation, storage configuration, and multi-container deployment workflows. This course is designed for software developers, system administrators, and IT professionals who are completely new to containerization, with no prior Docker experience required.
