Terraform Vars Cascade Processing

[Tensho]

Does it make sense to process terraform.tfvars files in all parent directories? Consider the next example:

prod
  us-east-1
    prod
      mysql
        terraform.tfvars # 1 (particular module level variables)
  terraform.tfvars # 2 (region level variable)
terraform.tfvars # 3 (account level variables)

Currently, there is only find_in_parent_folders(), which picks the first found terraform.tfvars file in the parent directories. In the example above we can merge only 1 and 2. It would be nice to adjust the function or create a new one (to not break backward compatibility), which would merge 1, 2, and 3.

People achieve described behavior with the hooks, but I think that should be in the "core".

Hi can you reopen this ticket on the terragrunt repo? (https://github.com/gruntwork-io/terragrunt). This repo is an example of how to use terragrunt, and so the issues are for reporting specific bugs in the example. This looks like a feature request for terragrunt itself, so doesn't really belong here.

Closing this ticket given above. Thanks and sorry for the extra steps.
