summary

Demo breaks two small apps and then fixes them live: first app fails because a required environment variable is missing — add the env var and the pod serves traffic; second app returns 502 because container listens on port 9898 while Service/Ingress target uses 8080 — changing the Service/targetPort to 9898 fixes it. Workflow uses kubectl get/describe, kubectl logs and kubectl port-forward to confirm pod health and connectivity and watches for endpoints empty to find service wiring issues.
