I have a simple service I would like to put in production. It is a simple ML code + Rest API + testing sandwich.

I only have one (virtual) server to run this on, but I still think Kubernetes looks really helpful, allowing me to throw new versions in test and update the production server without downtime.

Minikube is really nice to use, and everything seems to work well, however everywhere I read, I am told minikube shouldn't be used in production. Can anybody tell me if there's a reason for this? And if so what is the recommended setup for a single-node Kubernetes?

(Side question: Why does minikube run everything in a virtual machine? Doesn't that hurt performance?)
