Containerization with Docker: Foundations, CI/CD, and Kubernetes

Modern software development requires applications to run reliably across different environments, from a local laptop to cloud servers. Understanding containerization is no longer optional; it is a fundamental skill for developers, system administrators, and DevOps engineers. This text-based course guides you from the absolute basics of containerization to advanced deployment workflows, giving you the confidence to package applications, manage multi-container environments, and integrate containers into modern deployment pipelines. What you'll learn: - Understand containerization core concepts, terminology, and how containers differ from virtual machines. - Write optimized Dockerfiles using multi-stage builds and minimal base images to secure and shrink your containers. - Manage multi-container applications using Docker Compose for local development. - Implement container security best practices, including rootless execution and vulnerability scanning. - Integrate Docker containers into automated CI/CD pipelines for seamless deployment. - Explore orchestration fundamentals by deploying containerized services using Kubernetes. The course begins with foundational definitions and command-line basics before progressing to complex multi-container orchestration, configuration management, and security strategies. You will learn through clear written explanations, structured configuration examples, and practical text-based exercises. Designed for developers, system administrators, and technology enthusiasts new to containerization, no prior experience with Docker or DevOps is required. Start reading today to simplify your deployment workflows and master the essentials of modern container technology.
