Docker and Containerization Fundamentals for DevOps

Modern software development requires applications to run reliably across different environments, making containerization an essential skill for any aspiring DevOps professional. This course guides you from absolute beginner to confidently managing containers, explaining core concepts before moving into practical command-line workflows. What you'll learn: - Understand the core architecture of Docker, including containers, images, and registries. - Write efficient Dockerfiles using modern best practices like multi-stage builds to minimize image size. - Manage multi-container applications seamlessly using Docker Compose. - Configure persistent data storage using volumes and bind mounts. - Apply basic container security practices, such as running containers as non-root users. - Troubleshoot running containers using essential CLI diagnostics and log inspection. You will start with foundational definitions of virtualization and containerization, then progress through step-by-step written explanations and practical configuration scenarios that you can easily replicate on your own machine. This course is designed for beginners with no prior containerization experience. A basic familiarity with using a command-line terminal is helpful but not required.
