Docker Disk Space Management and System Pruning

Is your hard drive constantly running out of space due to accumulated container data? As you build and run containerized applications, unused layers, dangling images, and stopped containers quietly consume gigabytes of storage, slowing down your workflow. This text-based course provides a clear, step-by-step guide to understanding where Docker stores data and how to safely reclaim your disk space without disrupting active projects. You will transition from a cluttered system to a clean, highly efficient development environment by mastering Docker's built-in cleanup commands and storage management strategies. What you'll learn: - Understand how Docker manages storage, layers, and the local filesystem cache - Identify and safely remove dangling, unused, and duplicate Docker images - Clean up stopped containers, unused networks, and orphaned volumes - Use system prune commands with specific filters to avoid accidental data loss - Monitor real-time disk usage using built-in system commands - Establish automated maintenance habits to keep your development environment clean This course begins with foundational concepts, explaining how Docker's storage driver and layering system work before moving on to practical, command-line cleanup techniques. Through structured, text-only explanations and clear code examples, you will learn how to inspect your system, target specific resource types, and run precise pruning commands. This course is designed for beginners, developers, and system administrators who use Docker and want to keep their local environments running smoothly. No advanced DevOps experience is required.
