Containerization Basics with Docker CLI and Docker Engine

Containerization has revolutionized how software is built, packaged, and deployed. Understanding how containers run on your system is a fundamental skill for any modern developer or system administrator.\n\nThis text-only course guides you through the core concepts of containerization, starting from the ground up. You will gain a solid mental model of how Docker Engine interacts with your operating system, and you will learn to confidently manage containers using the command-line interface.\n\nWhat you'll learn:\n- Understand the foundational architecture of Docker Engine, including the roles of containerd and runc.\n- Run, stop, and manage container lifecycles using essential Docker CLI commands.\n- Configure container networking and persistent storage volumes for data consistency.\n- Apply modern container security best practices, such as running containers with non-root users.\n- Build lightweight custom container images using multi-stage build concepts.\n\nThe course begins with clear definitions of containerization terminology and architecture, then moves step-by-step into hands-on CLI command structures, and wraps up with essential security and storage configurations. Designed specifically for beginners, this course requires no prior experience with containers or DevOps tools—just basic familiarity with using a terminal.\n\nStart your journey into containerized environments and master the essentials of Docker today.
