`spec.replicaSet` represents the configuration for replicaset. When `spec.replicaSet` is set, KubeDB will deploy a mongodb replicaset where number of replicaset member is `spec.replicas`.
261+
262+
`.spec.replicaset.horizons` represents the configuration for mongodb replicaset to connect with external mongodb cluster. It has the following fields:
263+
- `dns` denotes the dns name for `srv` of the external mongodb cluster.
264+
- `pods` denotes the list of pods of external mongodb cluster.
255265

256266
- `name` denotes the name of mongodb replicaset.
257267
NB. If `spec.shardTopology` is set, then `spec.replicaset` needs to be empty.
