Hi everyone,
what is the function of ports 31400 and 15443 exposed by the default istio-ingressgateway config? Can they be removed if all I’m going to need for my application is port 80?

if you dig down into the downloaded helm source code included with your istio version at:

   /install/kubernetes/helm/istio/charts/gateway/values.yaml

You see stuff like this:

– Example of a port to add. Remove if not needed

  • port: 31400
    name: tcp
    nodePort: 31400

    – This is the port where sni routing happens

  • port: 15443
    targetPort: 15443
    name: tls
