Scenario Format

Each lab is a directory containing:

lab-name/
├── index.json      # Metadata: title, environment, steps
├── intro.md        # Context + objectives
├── setup.sh        # Seeds environment before user starts
├── step1/
│   ├── text.md     # Instructions
│   └── verify.sh   # Validation (exit 0 = pass, exit 1 = fail)
├── step2/
│   ├── text.md
│   └── verify.sh
└── finish.md       # Congratulations + next lab link

Environment Types

Type	Killercoda Image	Use Case
Ubuntu	ubuntu	Linux basics, shell, networking
Kubernetes	kubernetes-kubeadm-1node	K8s labs (single control plane + worker)

Authoring Guidelines

1. 3-6 steps per lab — focused, completable within time limit
2. Each step = one concept — don't overload
3. verify.sh must be deterministic — check exact state, not output format
4. setup.sh must be idempotent — safe to run multiple times
5. No copy-paste answers — steps require understanding
6. Hints in collapsible sections:

   <details>
   <summary>Hint</summary>
   Try `kubectl get pods -n production`
   </details>

Difficulty Calibration

Level	Steps	Hints	Guidance
Beginner	3-4	Generous, near-complete commands	High
Intermediate	4-5	Concept hints, not commands	Medium
Advanced	5-6	Minimal, doc references only	Low
