Docker, Finally Explained

Docker, Finally Explained is a complete, no-nonsense guide to containers — the technology that changed how software is built, shipped, and run. It skips the marketing and gets straight to work: images, containers, Dockerfiles, volumes, networks, Compose, multi-stage builds, registries, and CI/CD. From there it covers the production side: Docker Swarm, Kubernetes fundamentals, security, logging, monitoring, and the twelve-factor app. Every chapter is dense with real commands, tested patterns, and the reasoning behind each design decision. By the end, you will not just know what a container is — you will build, ship, and operate them.
