Question

A developer is deploying a database that needs each Pod to be individually addressable by a stable DNS name, rather than being load-balanced behind a single virtual IP. They ask how to configure the Service so that DNS returns the individual Pod IPs directly instead of a single ClusterIP. What should they do?

Accepted Answer

Set the Service's clusterIP field to None, creating a headless Service

Answer

Set the Service's type to NodePort so each Pod gets its own external port

Answer

Set the Service's type to LoadBalancer to expose each Pod separately

Answer

Set externalTrafficPolicy to Local so DNS resolves to Pod IPs
