Docker Basics for DevOps: Build and Deploy Containers

Modern software development requires applications to run reliably across different environments, from a local laptop to the cloud. Docker solves the classic "it works on my machine" problem by packaging applications and their dependencies into lightweight, isolated containers. This course guides you from containerization novice to confidently managing containerized applications. You will learn how to create, run, and orchestrate containers, establishing a solid foundation for any DevOps or modern software engineering role. What you'll learn: - Understand core containerization concepts, terminology, and the architecture of Docker - Run and manage containers using essential Docker CLI commands - Build custom container images using Dockerfiles and optimize them with multi-stage builds - Configure multi-container environments using Docker Compose - Apply basic container security practices and image management workflows - Manage container storage and networking to ensure persistent data and seamless communication The course begins with foundational definitions and architecture before moving into hands-on command-line practice. You will progress from single-container management to orchestrating multi-container applications and implementing optimization best practices through written explanations and code examples. This text-based course is designed for absolute beginners, software developers, and aspiring DevOps engineers. No prior container experience is required, though basic familiarity with the command line is helpful. Start reading today to unlock the power of modern containerized deployment.
