Whitelisting is not working. Here is my ingress yaml file.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: testing
  namespace: testing
  annotations:
    nginx.ingress.kubernetes.io/whitelist-source-range: "1.1.1.1/8"
spec:
  rules:
  - host: testing.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx
          servicePort: 80

After creating that ingress resource, I can still access the nginx website even though my IP is not included in the whitelist.
