I am trying sharding mongodbs. I have replicated the config server and also shards.But while connecting using router I get "Error: network error while attempting to run command 'isMaster' on host '127.0.0.1:60001'". I tried this but still getting same error. I am new to mongodb
I am using docker containers for each mongo instance Here is .yaml file
