Feature: Implement K8s Liveness and Readiness Probes

[fred-maina]

Description

The k8s/deployment.yaml file has livenessProbe and readinessProbe sections commented out. The application.properties file correctly exposes the Spring Boot Actuator endpoints (/actuator/health, /actuator/info) via management.endpoints.web.exposure.include.

These probes are essential for a stable Kubernetes deployment.

• Readiness Probes tell K8s when the app is ready to accept traffic.
• Liveness Probes tell K8s if the app has crashed and needs to be restarted.

Acceptance Criteria

1. Uncomment the livenessProbe and readinessProbe sections in k8s/deployment.yaml.
2. Ensure the httpGet path is correct (/actuator/health).
3. Set the port to 8080 (the containerPort).
4. Tune the probe settings:
   • initialDelaySeconds: Should be long enough for Spring Boot to start (e.g., 60 seconds for liveness, 30 for readiness).
   • periodSeconds: How often to probe (e.g., 10-15 seconds).
   • failureThreshold: How many failures before action (e.g., 3 for liveness, 5 for readiness).
