Reproducibility — One Command to Rebuild

A stack that only exists because you remember 15 manual setup steps isn't a stack -- it's a story you'll fail to reproduce the day your machine dies.

Hiring signal: A genuinely reproducible local environment -- survivable across a machine reinstall or a move to new hardware -- is what makes 'I run everything locally' a real, durable setup instead of a fragile one-time demo.

What you will learn

Finalize docker-compose.yml with all services and named volumes
Write a single startup script that rebuilds the entire stack
Verify docker compose down && docker compose up restores everything correctly

The Capstone Project

Everything works, right now, on this machine, because you built it step by step and remember every decision. Today's job: prove it survives you forgetting all of that — a real test of whether this is a system or just a memory.

The real test: tear it down and bring it back

docker compose down
docker compose up -d
docker compose ps

If either service comes back missing your chat history, your uploaded documents, or your Qdrant embeddings, something isn't using a named volume correctly -- go back and check every service's volumes: entry against Lesson 3 and Lesson 4's compose additions.

This is the actual test, not "it ran once"
"It worked when I first set it up" and "it survives being torn down and rebuilt" are different claims. Docker volumes persist data across down/up cycles specifically because you named them (open-webui-data, qdrant-data) rather than using anonymous or bind-mount-to-a-temp-path patterns. Running this teardown/rebuild test yourself, right now, is cheaper than discovering a gap the day your actual machine needs a reinstall.
