Installing Kubernetes on mac with vagrant and virtualbox
This is my first attempt to install and use Kubernetes. I am trying to install an environment on Mac for developing my own apps and deploying them for test locally with Kubernetes. I am familiar with using Vagrant, VirtualBox and Docker for the same purpose. When I saw this page https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/vagrant.md I assumed it would be trivial. I executed these lines:

Does AWS support Kubernetes?
I've read that AWS does not support Kubernetes and builds their own Docker orchestration engine EC2 Container Service. However, on Kubernetes getting-started -page there is a guide on how to run Kubernetes on AWS: https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/aws.md

What is the recommended way to upgrade a kubernetes cluster as new versions are released?
I heard here it may be https://github.com/kubernetes/kubernetes/blob/master/cluster/kube-push.sh. If that is the case how does kube-push.sh relate to https://github.com/GoogleCloudPlatform/kubernetes/blob/master/cluster/gce/upgrade.sh?

My Favorite DevTools to Build AI/ML Applications!
Deploying AI models into production requires tools that can package applications and manage them at scale. Docker simplifies the deployment of AI applications by containerizing them, ensuring that the application runs smoothly in any environment. Kubernetes, an orchestration system for Docker containers, allows for the automated deployment, scaling, and management of containerized applications, essential for AI applications that need to scale across multiple servers or cloud environments.

Building Llama as a Service (LaaS)
With the containerized Node.js/Express API, I could run multiple containers, scaling to handle more traffic. Using a tool called minikube, we can easily spin up a local Kubernetes cluster to horizontally scale Docker containers. It was possible to keep one shared instance of the database, and many APIs were routed with an internal Kubernetes load balancer.

Kubernetes and back – Why I don't run distributed systems
"You are holding it wrong", huh?
From the homepage https://kubernetes.io/:
"Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications."
Do you see "not recommended for smaller-scale applications" anywhere? Including on the entire home page? Looking for "small", "big" and "large" also yields nothing.
