Probes

CKAD v1.35 · Application Observability and Maintenance (15%) → "Implement probes and health checks" Target time: 7 minutes

Namespace dev needs a Deployment checkout (2 replicas, image nginx:1.27-alpine) with all three probe types correctly configured:

• startupProbe HTTP GET / on port 80, allow up to 60s for a slow start (periodSeconds 5, failureThreshold 12)
• readinessProbe HTTP GET / on port 80, initialDelaySeconds 2, period 5
• livenessProbe HTTP GET / on port 80, period 10, failureThreshold 3

The Deployment must reach 2/2 ready.
