Enable Per-Pod DNS Records for a Deployment

by Omkar Shelke

A service in the mesh namespace returns only a single IP during DNS lookup, preventing the peer-server pods from finding each other. Investigate why DNS does not return one address per pod and change the service configuration so that peer discovery works correctly.
