Hi there!
It looks like you may have resolved this issue in your stack overflow:
I figured out the issue, my pod DNS was not configured to allow external connections, so I set dnsPolicy: Default in my YML
Let me know if you have any additional questions.

Hi community,
Setting dnsPolicy: Default allows us to connect perfectly to mongodb atlas.
But, is there any way to get access to the mongodb atlas cluster without setting dnsPolicy: Default from DO K8s?
I also need communication with other services within the cluster.
I am using Istio and I have defined a Service Entry like this:
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
name: mongo-service-entry
spec:
hosts:
- xxx.mongodb.net
addresses:
- 0.0.0.0/0
ports:
- number: 27017
name: mongo
protocol: MONGO
location: MESH_EXTERNAL
resolution: NONE
But I can only get access white listening the droplets ip’s, something that obviously is not a good idea. Because these ip’s can change for example with autoscaling.
Thanks, Dalpheau
