Docker in Depth: From Basics to Orchestration

Overview

Docker changed how software gets built, shipped, and run. But most engineers learn just enough to get the app running locally — then hit a wall the first time something breaks in staging, or when they need to harden a container for production.

Docker in Depth is a 6-chapter series that builds a complete mental model: from how containers actually work, through networking and data persistence, multi-service orchestration with Compose, security hardening, CI/CD integration, and finally production-grade orchestration with Swarm and Kubernetes.

Each chapter is self-contained enough to reference directly, but the series is designed to be read in order — each layer builds on the last.

Who This Is For

Backend and fullstack engineers who understand basic Linux commands and have used Docker at least once — and want a structured, production-grade understanding from first principles through deployment pipelines.
