A tutorial that walks you through setting up highly available Kubernetes cluster by `Kubeadm`, therefore `the Kubeadm way`.

Kubernetes the Kubeadm Way

This tutorial, inspired by Kelsey Hightower's kubernetes-the-hard-way, walks you through setting up highly available Kubernetes cluster by using Kubeadm, therefore the Kubeadm way.

Google Cloud Platform will be used as it's really handy for me.
