Expose Service to Private Network with Minikube

You must have gotten a client where the client wants to see the results of the application work on Kubernetes, this we can use Nginx Proxy to reverse the IP service that is above Minikube to the IP private network around us. At least, if we can access it on our private network subnet, we can use the router to reverse private ip to public ip again.

Use Case

I want to expose my ReactJS apps to Private Network Subnet on Minikube. So user can access my ReactJS apps on Minikube with Private Network

I have an ReactJS apps run on Minikube with port 3000
