Manage Kubernetes Resources with Terraform

Hey there, Gurus! Welcome to the lab! This lab will demonstrate how to change, manage, and delete resources in Kubernetes using Terraform. You, as an admin, are being asked to deploy a NodePort service to your Kubernetes cluster to go along with your NGINX nodes. You will need to first set up the cluster using `kind` and `kubectl`, and deploy the NGINX nodes using Terraform. You will then use Terraform to deploy the NodePort service, and scale your NGINX nodes from 2 to 4 nodes. You will finish by destroying your resource and deleting your cluster.
