Details for installation of a k8s cluster using kind (k8s in docker)
kind create cluster --config kind-config.yaml
As hostname can only be localhost, only one service can use nginx-ingress at a time, in case services have common path. Let's say two services listen on path /healthz. Then ingress can only work for one of the created services on localhost/healthz, not both.
