We are using AWS EKS to deploy our k8 applications and we installed istio in it.
By default when AWS EKS is created we get AWS classic load balancer we attached wild card certificate to it.
so if am exposing my k8 service of type clusterIP and i want to attach different certificate for few k8 services how i can override the loadbalacer one i tried adding certificate to gateway using credentialName but its not working.
i tried the approach defined in this documentation but its not working -> https://istio.io/latest/docs/tasks/traffic-management/ingress/secure-ingress/#configure-traffic-for-the-bookinfo-com-host
Let me know is there any other way to manage different certificates.
