# Reflection: The Whole Toolkit Was Already Familiar

## Reflection questions

1. Which Docker command in this module felt like "a new version of something I already knew"
   from ROOT 01 or ROOT 02? Which felt genuinely new?
2. You ran, inspected, execed into, and removed a real container this module. What's the ONE
   command you'd reach for first if a container "seemed broken" and you didn't know why yet?

## Real Ops takeaway

**Every Docker command in this module is a direct translation of a Linux skill you already
had.** `docker ps` is `ps aux`. `docker logs` is reading a log file, minus the config. `docker
exec` is reaching into a running process. This is exactly why ROOT 01-02 came before ROOT 04 —
containers don't replace Linux fundamentals, they wrap them in a specific, consistent interface.

This module is complete. Continue to the next module.

## Instructor Notes

**Discussion questions for a live classroom:** question 2's honest answer is usually `docker ps`
or `docker logs` — a good moment to connect back to ROOT 02's five-question service checklist.

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