Docker: Containers from the Ground Up

by Shriira Press

Docker bundles an application with everything it needs into a portable container, so it runs the same everywhere. This free, example-driven book teaches it from the ground up: why containers beat VMs, running your first container, the core ideas of images and containers, writing Dockerfiles, how layers and the build cache make images fast and lean, persisting data with volumes, networking containers together, running multi-container apps with Docker Compose, sharing images through registries, and the practices that make containers production-ready. Ten focused chapters with real commands and clear diagrams. Learn the foundation of modern software delivery.
