I deployed a MongoDB replica set in my Kubernetes cluster. The **MongoDB replica set can be easily connected with the help of internal ClusterIP** within the cluster. I even connect it to my mongo-express client.

```
//Successfull and working fine internally
mongodb://db-mongodb-0.mycompany-mongodb-headless:27017/db

```

But I have to establish a remote connection for local testing and other services. I'm using the MongoDB helm chart provided by Bitnami. I opened a NodePort for both of my replica set at 30001 and 30002.

My first attempt to establish a remote connection was:

I **tried to connect with my previously opened NodePort**. I'm currently using Mongoose Client. The available node ports of my two replica sets are - 30001, 30002.

```
//Unsuccessful
mongoose
  .connect(
    `mongodb://username:password@<EXTERNAL_IP>:30001,<EXTERNAL_IP>:30002/mydb`,
    {
      useNewUrlParser: true,
      useUnifiedTopology: true,
    }
  )

```

Then my second attempt was -

I tried **port forwarding and tried to connect with my localhost** like this -

```
kubectl port-forward svc/database-mongodb-0-external 27017:27017

```

Then I tried to establish a connection like this and failed too

```
//Unsuccessful 
//MongoError: Authentication failed.
mongodb://username:password@localhost:27017/database

```

I tried ?replicaSet=rs0 query parameters in both of the cases too. But no luck.

I didn't try opening a LoadBalancer. Is there any way to **establish a remote connection with my Ingress-Nginx controller to my MongoDB services**? I don't know if it is possible but I tried to forward my headless services to a subdomain. But that subdomain is saying that - ***It looks like you are trying to access MongoDB over HTTP on the native driver port.*** I am not sure if it's possible!

But finally, my only question is, how can I establish or expose a remote connection with my MongoDB replica set which is set up at a Kubernetes Cluster?

My latest Bitnami/Mongodb values are
