Adds all 8 ROOT 04 modules (why containers exist, images & containers, Docker CLI, container networking, container storage, Dockerfile & image build, Docker Compose, containers → Kubernetes) — 43 activities, using the nested Docker Engine Phase 6D built and tested. Modules 1, 2, and 8 are conceptual (no lab by design) — the honest bridge module (M8) explicitly names what Kubernetes adds beyond what this course already taught, without re-teaching Kubernetes itself. Adds 5 new hands-on Docker scenarios plus 2 MCQs, all against the real nested Docker Engine: docker-cli-basics (run/exec/inspect a real container), docker-container-networking (a genuine "works internally, unreachable from host" port-publishing failure, diagnosed and fixed by recreating the container with the correct `-p` flag), docker-container-storage (a real destroy/recreate cycle proving named-volume persistence, not just described), docker-build-image (a real Dockerfile, a real build, a real custom image run), and docker-compose-multiservice (a real two-service Compose application with a real published port). All tested end-to-end via the real scenario-validation API, including negative tests. Wires rootnode-containers-assessment (2 required + 4 random-draw scenarios) using the existing Phase 3B assessment engine. This completes the entire ROOT_ Foundations sequence (ROOT 01-04) — see docs/PHASE6E_ROOT_FOUNDATIONS_COMPLETION.md. Co-Authored-By: Claude Sonnet 5 <[email protected]>

# Reflection: You're Ready, By Design, Not By Accident
|
|
|
|
## Reflection questions
|
|
|
|
1. Look back across ROOT 01 (Linux/processes), ROOT 02 (networking/troubleshooting), ROOT 03
|
|
(Git), and ROOT 04 (containers). Which single skill do you expect to use MOST once you start
|
|
ROOT 05?
|
|
2. Can you explain, in your own words and without looking anything up, why Kubernetes exists?
|
|
If you can't yet, which part of this module's lesson would you reread?
|
|
|
|
## Real Ops takeaway
|
|
|
|
**Every module across all four foundational courses was chosen deliberately to make THIS moment
|
|
make sense.** Processes (ROOT 01) become container processes become Pods. Filesystem/storage
|
|
(ROOT 01-02) becomes container volumes becomes Kubernetes storage. Networking/DNS/troubleshooting
|
|
(ROOT 02) becomes container networking becomes Services/Ingress/NetworkPolicy. Git (ROOT 03)
|
|
becomes the foundation for GitOps later. None of ROOT 05's content will be starting from zero —
|
|
you are walking in already equipped, on purpose.
|
|
|
|
This module — and the entire ROOT_ Foundations sequence (ROOT 01-04) — is complete. Continue to
|
|
ROOT 05: Kubernetes Foundations.
|
|
|
|
## Instructor Notes
|
|
|
|
**Discussion questions for a live classroom:** question 2 is the single best readiness check for
|
|
this entire foundational sequence — a confident, correct answer here is real evidence students
|
|
are ready for ROOT 05, not just that they clicked through four courses.
|
|
|
|
**Approximate timing:** 8-10 minutes live discussion; 5 minutes self-paced writing.
|
|
|
|
**Milestone note:** this is the last module of the entire ROOT_ Foundations sequence (ROOT 01-04)
|
|
— consider a genuine celebratory moment here for a live cohort; this represents a real, complete
|
|
skill foundation, not just a checkpoint.
