I am running 3 mongodb pods and separate service and persistent volume claims for each pod. I want to do the Mongodb replication among the 3 pods. Login into 1st pod and gave the mongo command, then i configured hosts as podname.servicename.namespace.svc.cluster.local:27017 for each pod.

rs.initiate(
  {
    "_id": "rs0",
    "members": [
      {
        "_id": 0,
        "host": "mongo-.mongo.default.svc.cluster.local:27017",
        "priority": 10
      },
      {
        "_id": 1,
        "host": "mongo-1.mongo.default.svc.cluster.local:27017",
        "priority": 9
      },
      {
        "_id": 2,
        "host": "mongo-2.mongo.default.svc.cluster.local:27017",
        "arbiterOnly": true
      }
    ]
  }
)

I am getting the error like this

replSetInitiate quorum check failed because not all proposed set members responded affirmatively: mongo-1.mongo.default.svc.cluster.local:27017 failed with Error connecting to mongo-1.mongo.default.svc.cluster.local:27017 (10.36.0.1:27017) :: caused by :: Connection refused, mongo-2.mongo.default.svc.cluster.local:27017 failed with Error connecting to mongo-2.mongo.default.svc.cluster.local:27017 (10.44.0.3:27017) :: caused by :: Connection refused

Here i have dought on whether cluster-IP or node-IP it takes as host while doing the MongoDB replication in kubernetes cluster.

Could anybody suggest me how to configure the host-name while doing the mongodb replication in kubernates?
