Docker: Containers to Production

A complete, hands-on path through Docker — from the shipping-container analogy and the Linux primitives containers are built from, through Dockerfiles, Compose, networking, and observability, to production hardening, image supply-chain security, and an orchestration primer that hands off cleanly into Kubernetes.

prerequisites

  • Comfort with the command line
  • Basic familiarity with any programming language and running an app locally
  • No prior Docker or container experience required

you'll learn

  • Understand what a container actually is — namespaces, cgroups, and union filesystems
  • Write production-grade Dockerfiles with multi-stage builds and layer-cache-aware ordering
  • Run multi-container applications with Docker Compose, volumes, and container networking
  • Ship containers safely — least-privilege users, health checks, logging, and CI/CD integration
  • Scan, sign, and harden the image supply chain before anything reaches production
  • Know when and why to reach for orchestration — Kubernetes, Swarm, and scaling patterns
