Kubernetes Configuration

I have included a .env, ingress-nginx.yaml, controller-nginx.yaml, and bash script that will build your cluster and deploys everything in your folder you specifify in the parameter for the bash script parameters

To deploy from your cloud-config/staging folder and create the cluster do this:

./deploy.sh staging y

If you want to upgrade your existing app deployment, simply remove the y
