### Cluster information:

minikube version: v1.18.1, virtualbox

Kubernetes version:  
Client Version: v1.20.4  
Server Version: v1.20.2

Cloud being used: (put bare-metal if not on a public cloud)  
Installation method:  
Host OS: macOS  
CNI and version:  
CRI and version:

I followed this instruction [GitHub - pkdone/minikube-mongodb-demo: Demo project showing how to deploy MongoDB in a local Minikube Kubernetes environment](https://github.com/pkdone/minikube-mongodb-demo) to setup a replicaset in mongodb.  
The final result consits: 3 pods and each of them consists one mongo process (mongod-0, mongod-1, mongod-2),these threre processes run on port 27017 , one service named ‘mongodb-service’ has targetPort 27017.

If I establish a connection from one of that processes using the connection string formatted “mongodb://mongo-0.mongodb-service:27017,mongo-1.mongodb-service:27017,mongo-2.mongodb-service:27017/admin?replicaset=MainRepSet” then it works .  
My issue is I want to access it outside the cluster, I tried to create an ingress that has 3 backends, but the ingress syntax does not allow backend.service.name as ‘mongod-0.mongodb-service’ as correct name.

Can anyone help me?

Did you try `monogd-1.namespace.mongodb-service`?
