Istio virtualservice uri匹配不起作用

Question

我是kubernetes和istio的新手。在GKE上，我创建了入口网关和两个虚拟服务。第一个是通往hipstershop的前端网关，第二个是通往我的helloworld服务器的dummyservice。但当我用打电话时

curl -v http://35.223.232.224/dummy

，显示Cannot GET/dummy错误。我确信我的dummyservice正在工作，因为我已经用Loadbalancer外部IP进行了测试。但我可以用http://ingress_ip.有人能帮帮我吗？

这是我的istio配置文件

apiVersion: networking.istio.io/v1alpha3
kind: Gateway

istio: ingressgateway # use Istio default gateway implementation

Answer 1

我的dummyservice node.js服务器仅在"/"url上提供服务。因此，返回的错误404不是来自ingress，而是来自我的node.js服务器。更改节点服务器中的基本路由解决了问题。

'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 worldn');
});
app.listen(PORT, HOST);
console.log(`Running on http://${HOST}:${PORT}`);
