如何在安装了 kubeadm 的 Kubernetes 集群上配置 Ingress Controller

Question

I installed a Kubernetes cluster with "kubeadm" on Hetzner Cloud.

After successful installation, I installed the Ingress Controller with Helm.

The EXTERNAL-IP of the ingress controller service is in the pending state. The default type is LoadBalancer and as I know this type is only supported by cloud providers like AWS, Google...

So I changed the service type to NodePort.

How should I configure the external DNS to my services?

I don't want to append the 3.... ports but let the Ingress controller manage that for me.
