# Tech tracking
tech-stack:
  added: [Diátaxis framework documentation]
  patterns: [4-quadrant documentation structure, tutorial-driven learning, reference tables for cloud parallels]

key-files:
  created: [labs/lab-01-iam/tutorial/*.md, labs/lab-01-iam/how-to-guides/*.md, labs/lab-01-iam/reference/*.md, labs/lab-01-iam/explanation/*.md]
  modified: []

key-decisions:
  - "Italian language for all documentation (as per CLAUDE.md)"
  - "No emojis in documentation (as per plan requirements)"
  - "Direct, simple language with step-by-step verification"
  - "IAM parallels prominently featured in tutorials and explanation"

patterns-established:
  - "Pattern 1: Each tutorial follows 'little often' principle with small incremental steps"
  - "Pattern 2: Every tutorial has troubleshooting section"
  - "Pattern 3: Cross-references between related documents"
  - "Pattern 4: Side-by-side comparison tables for local/cloud concepts"

requirements-completed: [LAB-01, DOCT-01, DOCT-02, DOCT-03, DOCT-04, DOCT-05, PARA-01, PARA-03, PARA-04]

# Phase 2 Plan 02: Diátaxis Documentation Summary

**Complete Diátaxis framework documentation for Lab 01 IAM & Sicurezza with 10 files covering tutorials, how-to guides, reference specs, and IAM parallelism explanations**

## Performance

- **Duration:** 4 min
- **Started:** 2026-03-24T21:23:26Z
- **Completed:** 2026-03-24T21:27:15Z
- **Tasks:** 6
- **Files modified:** 10

## Accomplishments

- Created 3 tutorial documents following step-by-step "little often" principle
- Created 3 how-to guides for common IAM procedures
- Created 3 reference documents with technical specifications and tables
- Created 1 explanation document mapping Docker concepts to AWS IAM
- All documentation in Italian without emojis as per project guidelines
- All files include cross-references to related content

## Task Commits

Each task was committed atomically:

1. **Task 1: Create Tutorial - Part 1: Linux Users** - `b130b1c` (feat)
2. **Task 2: Create Tutorial - Part 2: Docker Group Permissions** - `b031f58` (feat)
3. **Task 3: Create Tutorial - Part 3: Verification and Non-Root Containers** - `7bd6111` (feat)
4. **Task 4: Create How-to Guides** - `c759270` (feat)
5. **Task 5: Create Reference Documents** - `cc3a28f` (feat)
6. **Task 6: Create Explanation Document (IAM Parallels)** - `7723582` (feat)

**Plan metadata:** TBD (docs: complete plan)

## Files Created/Modified

### Tutorials (3 files)
- `labs/lab-01-iam/tutorial/01-create-linux-users.md` - Step-by-step user creation guide with verification
- `labs/lab-01-iam/tutorial/02-docker-group-permissions.md` - Docker group permissions with IAM parallels
- `labs/lab-01-iam/tutorial/03-verify-iam-setup.md` - Verification and non-root container execution

### How-to Guides (3 files)
- `labs/lab-01-iam/how-to-guides/add-user-to-docker-group.md` - Quick guide for adding users to docker group
- `labs/lab-01-iam/how-to-guides/verify-non-root-container.md` - Multiple methods to verify non-root execution
- `labs/lab-01-iam/how-to-guides/reset-docker-permissions.md` - Complete permission reset guide with troubleshooting

### Reference Documents (3 files)
- `labs/lab-01-iam/reference/docker-socket-permissions.md` - Docker socket technical specifications
- `labs/lab-01-iam/reference/linux-users-groups.md` - Linux user management reference
- `labs/lab-01-iam/reference/iam-parallels.md` - Quick reference table for IAM parallelism

### Explanation (1 file)
- `labs/lab-01-iam/explanation/docker-iam-parallels.md` - Conceptual mapping between Docker and AWS IAM with practical examples

## Decisions Made

- Italian language used throughout all documentation (as per CLAUDE.md requirements)
- No emojis used in any documentation (as per plan specifications)
- Each tutorial includes troubleshooting section for common issues
- Cross-references included between related documents (tutorial → how-to → reference → explanation)
- IAM parallels prominently featured to meet PARA-01, PARA-03, PARA-04 requirements
- "Little often" principle applied with small incremental steps and verification

## Deviations from Plan

None - plan executed exactly as written. All 6 tasks completed without deviations:
- Task 1: Tutorial part 1 created with 162 lines (60+ required)
- Task 2: Tutorial part 2 created with 180 lines (60+ required) and IAM parallels
- Task 3: Tutorial part 3 created with 232 lines (40+ required) and INF-01 coverage
- Task 4: 3 how-to guides created with 20 sections total (9+ required)
- Task 5: 3 reference documents created with 15+ tables
- Task 6: Explanation document created with 361 lines (80+ required) and AWS IAM coverage

All verification tests passed. No auto-fixes were needed.

## Issues Encountered

None - all tasks executed smoothly without issues.

## User Setup Required

None - no external service configuration required. All documentation is self-contained within the repository.

## Next Phase Readiness

- Diátaxis documentation complete and ready for student use
- All 4 quadrants (Tutorial, How-to, Reference, Explanation) implemented
- Test infrastructure from plan 02-01 integrates with documentation
- Ready for plan 02-03 (implementation phase - GREEN phase to make tests pass)

The documentation establishes the foundation for students to learn IAM concepts through local Docker/Linux user management, with clear parallels to AWS IAM for knowledge transfer to cloud environments.
