Example Lesson Structure

From lessons/03-pods-deployments.md:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    spec:
      containers:
      - name: nginx
        image: nginx:1.21
        resources:
          requests:
            memory: "64Mi"
            cpu: "100m"

Followed by progressive concepts: multi-container pods → probes → rolling updates → rollbacks.
