I have deployed mongodb on Kubernetes using mongodb-operator (verison: 1.9.2). The ReplicaSet consists of 3 instances: 1 primary and 2 secondary. I am able to access the ReplicaSet from any of given Kubernetes pods but if I try to do the same from the local machine with pymongo client I am getting error as shown below. Can anyone suggest the reason for such behavior?

pymongo.errors.ServerSelectionTimeoutError: mongodb-2.mongodb-svc.mongodb-new.svc.cluster.local:27017: [Errno -2] Name or service not known,mongodb-0.mongodb-svc.mongodb-new.svc.cluster.local:27017: [Errno -2] Name or service not known,mongodb-1.mongodb-svc.mongodb-new.svc.cluster.local:27017: [Errno -2] Name or service not known, Timeout: 30s, Topology Description: <TopologyDescription id: 610292f511a5060cc91f8a11, topology_type: ReplicaSetNoPrimary, servers: [<ServerDescription ('mongodb-0.mongodb-svc.mongodb-new.svc.cluster.local', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('mongodb-0.mongodb-svc.mongodb-new.svc.cluster.local:27017: [Errno -2] Name or service not known',)>, <ServerDescription ('mongodb-1.mongodb-svc.mongodb-new.svc.cluster.local', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('mongodb-1.mongodb-svc.mongodb-new.svc.cluster.local:27017: [Errno -2] Name or service not known',)>, <ServerDescription ('mongodb-2.mongodb-svc.mongodb-new.svc.cluster.local', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('mongodb-2.mongodb-svc.mongodb-new.svc.cluster.local:27017: [Errno -2] Name or service not known',)>]>
