Creating a Low Cost Managed Kubernetes Cluster for Personal Development

Here's my take on setting up a managed Kubernetes cluster using Terraform with very low costs using a free(only 1 per account) zonal cluster with preemtible node pools (spot instances) on GKE. I've linked GCP's pricing calculator in the blog post as well(https://cloud.google.com/products/calculator/#id=b3d304a4-11...). A 2vCPU and 8GB RAM node running in a GKE cluster for ~$20.

Hopefully it'll make it easier for people to set up their own experimentation environment for learning Kubernetes since managed Kubernetes is quite pricey otherwise for personal development.
