istio create external ip for specific service

Question

I've deployed successfully an app to K8s with istio

We have gw which we use and virtual service like the following:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: bher-virtualservice
  namespace: ba-trail 
spec:
  gateways:
    - bher-gateway 
  hosts:
    - trialio.cloud.str
  http:
    - match:
      - uri:
          prefix: "/"
      - uri:
          prefix: "/login"
      - uri:
          prefix: "/static"
      - uri:
          regex: '^.*\.(ico|png|jpg)$'
      route:
      - destination:
          host: bsa.ba-trail.svc.cluster.local service.namespace.svc.cluster.local
          port:
            number: 5000

I defined also a service and deployment.

I want to expose the service outside that I will be able to access like:

https://myapp.host:5000

when I run:

kubectl get svc istio-ingressgateway -n istio-system


NAME                   TYPE           CLUSTER-IP       EXTERNAL-IP                                                                  PORT(S)                                      AGE
istio-ingressgateway   LoadBalancer   100.61.114.202   a7151b2063cb-200880.eu-central-1.elb.amazonaws.com   150210:31161/TCP,80:31280/TCP,443:31190/TCP   41d

How it can be done?

I was able to run the app with port forwarding but I want a direct external link.

Answer 1

So in your case, you have an ELB serving your istio ingress gateway that goes to a VirtualService that directs traffic to port 5000 in the container.

I assume that you have it working with
