Access from AWS Lambda function to Istio Ingress ELB

Hello,

We have AWS Lamda functions for each environment and they need to access Istio Ingress ELB for talking the services in K8s clusters.

One way looks to be to add the security group in the Lamda function to the Ingress ELB security group. But I don’t see an option to do this using “loadBalancerSourceRanges” in the istio-ingressgateway service yaml definition.

How can we achieve this?

Thanks
