Kubernetes Load balancer allow access to certain domain

I have a Django application running on kubernetes with a load balancer. I keep getting a lot of Invalid http_post email. Is there a way for me to block other traffic. On a server that is running nginx i can write this in the configuration file

    if ($host != "") {
        return 404;

Is there a way for me to do something similar in the service yaml file for my load balancer or at least not allow it to touch my Django deployment on the kubernetes if the allowed domain is not in a list specified by me

Hi there,

Yes, I believe that you should be able to do that with Nginx Ingress.

You can follow the steps on how to set that up using Helm here:

Or if you prefer, you could use the Marketplace instead:

Then you can add different host rules, eg:

kind: Ingress
  name: ingress-echo
  namespace: backend
  ingressClassName: nginx
    - host:
          - path: /
            pathType: Prefix
                name: echo
                  number: 8080

Hope that this helps!
