Does this actually work?

I noticed the terragrunt.hcl file is missing. Not sure how to properly use this repo as a reference.

[robcxyz]

The terragrunt.hcl is for the newer versions of terragrunt when terraform switched to v0.12. For terraform versions <v0.11, terraform.tfvars was the convention. Other than that they are the same.

[sdot257]

Yeah I finally figured that out BUT my next issue is that I don't think the variables are being passed into the module.

terraform {
  source = "github.com/terraform-aws-modules/terraform-aws-vpc.git"
}

  path = find_in_parent_folders()
}

This repository is using the previous major version of Terragrunt which is compatible with Terraform 0.11.

I will update this repo, but in the meanwhile, you can take a look at modules.tf-demo repo which works with recent Terragrunt and Terraform 0.12.
