Description
The problem runs on hotel-reservation. Simulate an admission outage where a ValidatingWebhookConfiguration intercepts pod creation but points to a missing backend service. The webhook uses failurePolicy Fail, so the Kubernetes API server rejects replacement pods and leaves the recommendation deployment under-replicated even though its deployment specification is valid. Inject the fault by installing the broken webhook and deleting the current recommendation pod to trigger a blocked replacement.
