mongodb - Load Balancing Mongo DB on GCE instance -


the default click deploy mongodb gce sets 1 primary node, 1 secondary node , 1 arbiter node. can't figure out how mongodb manages distribute reads between primary , secondary nodes. have explicit external ip each node available don't want point apps 1 node or other ... how figure out load-balancer ip (if there such thing) can give app mongodb connection url?

in order connect replica set of mongodb, need specify hosts in standard uri connection scheme. example, describe connection replica set named test, following mongod hosts: 

db1.example.net on port 27017 db2.example.net on port 2500

you use connection string resembles following: 

mongodb://db1.example.net,db2.example.net:2500/?replicaset=test

for more information mongodb's connection string uri format, take @ artcile.
