Question

我正在使用节点js创建代理服务器，并希望将来自一个Pod的请求代理到kubernetes的单节点集群中的其他Pod。这是我的节点js代码，、、、

const express = require("express");
const httpProxy = require("express-http-proxy");
const app = express();

const serviceone = httpProxy("serviceone:3000"); // I am using service names here but its not working

// Authentication
app.use((req, res, next) => {
  // TODO: my authentication logic
  console.log("Always.....");
  next();
});

app.get("/", (req, res, next) => {
  res.json({ message: "Api Gateway Working" });
});

// Proxy request
app.get("/:data/api", (req, res, next) => {
  console.log("Request Recieved");
  serviceone(req, res, next);
});

app.listen(5000, () => {
  console.log("Api Gateway Running");
});

这些是我的services.yml文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: serviceone
  labels:
    app: serviceone
spec:
  replicas: 1
  selector:
    matchLabels:
      app: serviceone
  template:
    metadata:
      labels:
        app: serviceone
    spec:
      containers:
      - name: serviceone
        image: swa/serviceone
        ports:
        - containerPort: 3000
---
apiVersion: v1
kind: Service
metadata:
  name: serviceone
spec:
  selector:
    app: serviceone
  ports:
  - protocol: TCP
    port: 3000
    targetPort: 3000
    nodePort: 31000
  type: LoadBalancer

我应该在http代理中使用什么名称，以便它可以代理请求？

我尝试了serviceone:3000，http://serviceone:3000，http://localhost:3000（不适用于不同的广告连播）。任何帮助将不胜感激

编辑-Node js apigateway pod

在我的node js应用程序中，我将URL更改为

const serviceone = httpProxy('serviceone.default.svc.cluster.local:3000');

通过点击此链接https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#services 但仍然没有运气

我遇到了错误

错误：getaddrinfo EAI_AGAIN servicethree.sock-shop.svc.cluster.local 在GetAddrInfoReqWrap.onlookup上[按完成状态]（dns.js：66：26）

Kubernetes从另一个访问一个Pod URL
