Description
The problem runs on social-network. Simulate a fault where the DNS policy is incorrectly configured for the user-service in the social network application. The deployment `user-service` has a misconfigured DNS policy (set to None with external nameserver 8.8.8.8), causing DNS resolution failures for cluster-internal services. Inject the fault by setting an incorrect dnsPolicy (e.g., Default instead of ClusterFirst) for the user-service pods.
