Follow kong installation guide. Or you can choose another ingress controller.
https://github.com/Kong/kubernetes-ingress-controller
Or just run to apply kong ingress controller:
kubectl apply -f https://bit.ly/k4k8s
Make sure that the Ingress class is set by default.
Set:
kubectl annotate ingressclass kong ingressclass.kubernetes.io/is-default-class=true
*You should change “kong” (e.g. nginx) into the following command if you use another Ingress controller.
