I am new to kubernetes and istio. On GKE, I have created ingress-gateway and two virtual services. The first one is frontend-gateway that routes to hipstershop and the second one is dummyservice which route to my hello world server. But when I call with
curl -v http://35.223.232.224/dummy, it shows Cannot GET /dummy error.I'm sure my dummyservice is working since I have tested with Loadbalancer external IP.But I can call to hipstershop with http://ingress_ip. Can someone please help me?
Here is my istio config file
apiVersion: networking.istio.io/v1alpha3
kind: Gateway

istio: ingressgateway # use Istio default gateway implementation

My dummyservice node.js server is only serving on "/" url. So the error 404 returning is not from ingress but from my node.js server.Changing my base route in node server solved the issue.
'use strict';
const express = require('express');
// Constants
const PORT = 80;
const HOST = '0.0.0.0';
// App
const app = express();
app.get('/dummy', (req, res) => {
res.send('Hello world\n');
});
app.listen(PORT, HOST);
console.log(`Running on http://${HOST}:${PORT}`);
