How can we achieve the same thing for Talos Linux?

"Also you need to modify the k3s service to change port range the way I presented. Without this it will not work, just because I am using a NodePort 5678 and by default Kubernetes is using a range for ports between 30000 and 32767. "

I'm not using k3s; instead, I'm utilizing Talos Linux. Additionally, with Talos Linux, I don't have access to SSH.

I received a reply from Talos stating that it's not a Talos issue but rather lacks Kubernetes best practices.

I created a tutorial for k3s cluster not for Talos. So if you are using Talos, try to find out is it possible to modify the range. Or stay with the standard port instead modifying the service change the port from 5678 to 30000. Just 5678 is a default port for n8n and the problem is that the Kubernetes best practices are using by default this range: 30000 and 32767. So, f it says that the port is wrong, and you cannot modify the service in Talos (I do not know this) just modify the port in file nginx-ingress-n8n-service.yml as I wrote and implement the yaml file using the below command:
kubectl apply -f ingress/nginx-ingress-n8n-service.yml
What I did, I modified the port against Kubernetes best practices, to show that it is possible. Is it secure? Yes, but only if you work with the environment you can secure by isolating it from the Internet and also by isolating it using VLANs inside your network.
