# Reflection: A Small Distinction With Large Consequences

## Reflection questions

1. Before this module, would you have known why `docker rm` and `docker rmi` are two separate
   commands? Does it make sense now?
2. Where else in ROOT_ have you seen this exact "artifact vs. running instance" pattern before?
   (Hint: think back to ROOT 01.)

## Real Ops takeaway

**Precise vocabulary prevents real mistakes.** Confusing "stop the container" with "delete the
image," or assuming `latest` means "the current version," are genuine, common sources of
production incidents — not just semantic nitpicking. The image/container distinction you just
solidified is the foundation every command in the rest of this course builds on.

This module is complete. Continue to the next module.

## Instructor Notes

**Discussion questions for a live classroom:** question 2's intended answer is "program vs.
process," from ROOT 01 — a good moment to explicitly connect the two courses.

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