Load-balancer multi ports

Networking
1

Hi all,
I am using Istio on Minikube with tunnel and it works very well.

I installed the “demo” profile

Now I’d like to add another port to the load-balancer:

currently, I have:

 PORT    STATE  SERVICE
 80/tcp  open   http
 443/tcp closed https

I’d need to open another port, I tried in this way:

spec:
  selector:
    istio: ingressgateway # use Istio default gateway implementation
  servers:
    - port:
        number: 80
        name: http
        protocol: HTTP
      hosts:
        - "*"
    - port:
        number: 5672
        name: tcp
        protocol: TCP
      hosts:
        - "*"

but didn’t work.
Is there a way to open another port?
Thank you

Hello,

unfortunately this is not enough. You have to specifying the port also on the istio-ingressgateway service.

Thank you Tomas for your answer,
I was trying to change the stio-ingressgateway configuration, but what it is not clear to me is with this configuration:

Name:                     istio-ingressgateway
Namespace:                istio-system
Labels:                   app=istio-ingressgateway

I see only the port 80 exposed.

I do not understand how to expose the other ports, let’s suppose the Prometheus port.

I think that your port name is wrong. It should be protocol-whatevever.
