Kubernetes Ingress. Send http traffic to a port and https traffic to other port

Question

Using k8s ingress, is it possible using the same domain send incoming http traffic to a port and https traffic to other port?

I have not find anything in the ingress sepecification to do it or annotations in nginx-ingress-controller

Answer 1

You will need two objects i.e, service and ingress for this. You need to configure ingress similar to below:

spec:
  rules:
  - host: abc.com
    http:
      paths:
      - backend:
          serviceName: myservice
          servicePort: 80
        path: /uiaccesscontrol
      - backend:
          serviceName: myservice
          servicePort: 443
        path: /uiaccesscontrol

and service will have configurations similar as given below:

spec:
  ports:
    - name: http
      port: 80
      targetPort: 80
    - name: https
      port: 443
      targetPort: 443

Now, https traffic will be routed to secure port 443 and http to 80.
