Ingress

Ingress für Websockets

Für Websockets benötige ich 2 Ingress Definitionendamit der Ingress .
Einen für den SubpfadPfad und einen für die Socket.io Library.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    certmanager.k8s.io/cluster-issuer: core-prod
    nginx.ingress.kubernetes.io/proxy-read-timeout: "1800"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "1800"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/secure-backends: "true"
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
    nginx.ingress.kubernetes.io/websocket-services: websockets-service
  name: "websockets-ingress"
spec:
  ingressClassName: public
  rules:
    - host: kimo2007.dnshome.de
      http:
        paths:
          - path: /ws2
            pathType: Prefix
            backend:
              service:
                name: websockets-service

Express Javascript

var io = require('socket.io')(server,{
  path:'/ws/socket.io',
  methods: ["GET", "POST"],
  credentials: true,
  transports: ['websocket', 'polling'],
  //  rejectUnauthorized: false,
    allowEIO3: true, // false by default
    serveClient: true
  });


var cors = require('cors');

app.use(cors());
