Docker Under the Hood is a deep dive into the world of containerization with Docker. It is a technical book, but it is easy to read for any IT consultant, with a particular focus on DevOps engineers. Each chapter begins with a short overview and then continues with a practical technical section, often including a hands‑on example. At the end of every chapter, you’ll find a brief recap of what you’ve learned. The book is a great introduction to the world of images and containers, especially if you want to get started with Kubernetes.

Docker Under the Hood takes you beyond copying commands from tutorials and shows you what actually happens inside your containers.

In this book, you’ll learn how Docker builds, stores, and runs images, how containers are isolated under the hood, and what really goes on when you type docker run. You’ll explore networking, volumes, and resource limits in a practical way, so you finally understand why things work (or break) in real‑world setups.

We also dive into topics like multi‑stage builds, image optimization, security best practices, logging and monitoring, and how Docker fits into CI/CD pipelines and orchestration platforms such as Docker Swarm and Kubernetes. Along the way, you’ll see clear examples, diagrams, and troubleshooting tips drawn from real production experience.

Whether you’re a developer, DevOps engineer, or sysadmin, Docker Under the Hood gives you the mental model you need to design, debug, and optimize containerized applications with confidence.
