Docker and CI/CD Fundamentals

Containerize a sample app and author a basic CI pipeline with checks and a runbook.

Problem statement · Illustrative

A sample application needs a repeatable container build and a CI pipeline that fails closed when checks fail.

Primary user workflow · Illustrative

Commit change → pipeline runs checks → image builds → pipeline status is visible → runbook explains how to run the image.

Functional scope · Illustrative

Dockerfile or equivalent, CI configuration, basic checks, image hygiene, and deployment documentation.

Technical components · Illustrative

Sample app, container definition, CI config, and runbook.

Data requirements · Illustrative

No production datasets. Secrets via environment variables only.

Testing expectations · Illustrative

Pipeline fails on a deliberate check failure and succeeds on the happy path.

Known limitations · Illustrative

Not a full multi-environment production platform. Paid cloud deploy targets are not assumed.

What counts as completion · Illustrative

Working pipeline, containerized sample app, and a short runbook.
