You need Make to use Makefile

Use Minikube to test it locally

• Install Minikube

• Start Minikube

  make start

• Wait till the start is complete and proceed

Deployment

• Make sure Minikube is running and your kubectl is configured to use it

  $ make status
  
  --- OUTPUT ---
  type: Control Plane
  host: Running
  kubelet: Running
  apiserver: Running
  kubeconfig: Configured
  
  $ kubectl config current-context
  
  --- OUTPUT ---
  minikube
  

• Go to the ci-cd folder and go through the README.md to create SA for the deployment process specifically

• Deploy all files to the cluster

  make deploy_all

• Check that Nginx homepage is loading

  make port_forward

  Open http://localhost:30555 or http://127.0.0.1:30555 in your brouser. You should see Nginx welcome page
