Missing sample connection URL in README

[djensen47]

It might be nice to include what the connection URL would be inside the cluster for this setup.

It seems like it would be:

mongodb://mongod-0.mongodb-service,mongod-1.mongodb-service,mongod-2.mongodb-service:27017/dbname

Did you ever manage to connect? I can't seem to figure it out, this is the url I'm trying:

`mongodb://${MONGO_CONFIG.auth.user}:${MONGO_CONFIG.auth.password}@mongod-0.mongodb-service,mongod-1.mongodb-service,mongod-2.mongodb-service:27017/${DB_NAME}`

The url I posted works for me.

@djensen47 thanks 👍

I would rather leave the primary/secondary handling for the service itself, so I am using this: mongodb://user:[email protected]/?replicaSet=MainRepSet&authSource=admin (I also have 3 replicas)

That gives you this (I am debugging it with a Java app), note the other replica hostnames handled automatically:
