Istio Ingress-Gateway problem

Networking
1

Hi guys.
How are you?
I’m newer user of Istio and I’ve a question about my Istio installation.

I’ve EKS Cluster with Fargate profile and a sample application that works using fargate. When I use LOAD BALANCER URL my sample application works correctly but I need to use istio ingress-gateway and when I applied .yaml file and used URL of istio-ingress-gateway my application doesn’t work.

Can you help me?

kind: Gateway
metadata:
name: javappsample-gateway
namespace: devops
spec:
selector:
istio: ingressgateway # use Istio default gateway implementation
servers:

number: 80
name: http
protocol: HTTP
hosts:

Welcome to the forums!

Does the traffic actually reach your ingressgateway on port 80? Does it show any access log entries?

Also try “istioctl analyze -n devops” for some general validation of your configuration.

I dont know. I can access my app using service url, but using ingressgateway url I cant.

I ran and is this output:

What’s this host ? Pod name? service name? Deployment name?
