Encapsulating clusters as Terraform modules

You can provision multiple EKS clusters with a single terraform apply:

terraform init
terraform plan
terraform apply

It might take a while for the cluster to be created (up to 15-20 minutes).

At the end you will have:

1. A cluster for development.
2. A cluster for staging.
3. A cluster for production.

In the same folder, you will find a kubeconfig file for each cluster.
