Docker Fast Track

From zero to containerizing a real application.

35 modules · 7 quizzes · ~231 menit · 3 preview gratis

Never run a single container? This course takes you from nothing to containerizing a real application — 35 compact, hands-on modules.

What you will master:

The difference between image, container and registry — and why a container is not a "small VM"
The commands you actually use daily: run, ps, logs, exec, and reading exit codes when a container dies on you
Writing Dockerfiles that build fast: layer order, build cache, .dockerignore, and multi-stage
Data that survives docker rm (volumes), bind mounts for development, and DNS between containers
Docker Compose: one file, one command, the whole stack alive — including healthcheck, so your app does not start before the database is ready
Capstone workshop: containerize a Node.js + PostgreSQL app end-to-end, through hardening to a v1.0 release

Who it is for: developers comfortable at a terminal who have never used Docker. Command examples cover Windows, macOS and Linux alike.

Everything follows the official Docker documentation, condensed into a fast track with practical notes from real use. Each part closes with a quiz, and your progress saves itself.
