After deploying a ClusterIP Service for a civic payments API, the developer needs to verify in-cluster reachability before opening Ingress. What is the most appropriate quick check?
Select an answer to reveal the explanation.
Short Explanation
To see what other Pods see, stand inside the cluster for a minute. A throwaway debug Pod curling svc-name.namespace.svc or the ClusterIP is the classic reachability smoke test. Laptop-to-Pod-IP shortcuts skip the Service path you care about.
Full Explanation
ClusterIP Services are reachable from Pods inside the cluster via virtual IP and DNS (for example my-svc.my-ns.svc.cluster.local). Spinning up a short-lived debug Pod and curling that name or ClusterIP validates kube-proxy/CNI, Endpoints, and DNS together. Testing only a Pod IP from outside, breaking CoreDNS, or converting to NodePort just for a laptop check does not faithfully verify ClusterIP Service behavior.
