# Reflection: A Real Multi-Service Application, Described and Running

## Reflection questions

1. Before this module, how would you have run two related containers and connected them
   manually? How does that compare to this module's Lab?
2. What does a Compose file's `services:` block remind you of, from ROOT_'s later Kubernetes
   content — even without knowing Kubernetes syntax yet?

## Real Ops takeaway

**You just described and ran a real multi-container application declaratively — the exact same
"describe what you want, let the tool make it real" pattern behind every later Kubernetes manifest
in this program.** This isn't a coincidence: Compose and Kubernetes both solve "orchestrate
multiple containers as one application," at different scales. The habit of thinking in terms of
declared services rather than manual step-by-step commands is what ROOT 05 builds on directly.

This module is complete. Continue to the final module of this course.

## Instructor Notes

**Discussion questions for a live classroom:** question 2 previews Kubernetes manifests
directly — a good moment to name "declarative description of desired state" as a term students
will hear constantly starting in ROOT 05.

**Approximate timing:** 5-8 minutes live discussion; 5 minutes self-paced writing.
