This example shows how Terragrunt can be used to deploy a single Terraform configuration to multiple environments where each of the environments has a different set of parameters.
Terraform configuration is loaded from an external repository: https://github.com/bartosz347/terraform-playground/tree/master/k8s-digitalocean
E.g. module k8s-cluster deploys a k8s cluster. Number of worker nodes can be changed independently for dev and prod.
terragrunt.hcl files present in terraform configuration repository (external repository) are skipped.
