Docker and Containers in Practice: Build, Ship and Run Containers Yourself — the free Preview

This page is the real first concept of Docker and Containers in Practice: Build, Ship and Run Containers Yourself (Signature Course No. 456) — not a trailer and not a video. You work through Concept 1, “Image, Container, and the Line Between Them,” in a Socratic conversation with an AI coach: she asks before she teaches, builds on your own answers, and holds you to a mastery bar before the concept counts as done.

What this course teaches. Build, ship, and run containers yourself: images built in layers against the cache and kept small and honest by construction, shipped through a registry under tagging and promotion discipline you can prove by digest, and run on hosts you own — configuration supplied at run time, data placed to outlive the container, and health, rollback, security, and day-two judgment throughout. Dockerfiles are taught as decisions, not syntax drills, and Compose — a declared multi-container application on your own host — is the course's stated ceiling.
