An example Ingress that makes use of the controller:

- host: www.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: exampleService
port: 80
# This section is only required if TLS is to be enabled for the Ingress
tls:
- hosts:
- www.example.com
secretName: example-tls
If TLS is enabled for the Ingress, a Secret containing the certificate and key must also be provided:
apiVersion: v1
kind: Secret
