Problem loading configurations from a parent directory about terragrunt-reference-architecture HOT 7 CLOSED

Hi there!

You need to start debugging from an internal directory and try to get it to work first:

cd terragrunt/staging/eu-central-1/vpc
terragrunt init
terragrunt apply

Then you can go one level up and try to run terragrunt apply-all.

I don't think I have simple+working Terragrunt code in the open-source where common.tfvars is used but maybe you can see how I write it in other places, too:
https://github.com/antonbabenko/modules.tf-demo
https://github.com/terraform-aws-modules/meta

In general, the questions related to the terragrunt are better to ask on the official repository as there are more users who may help you.

Good that it works!

Yes, yamldecode is an option if you want to deal with YAML or have a lot of variables.

I usually prefer to deal with hcl files using read_terragrunt_config() as I have here - https://github.com/terraform-aws-modules/meta/blob/master/github/repositories/terraform-aws-modules/terraform-aws-appsync/terragrunt.hcl#L10

That worked great and was much more intuitive as well. Thanks again as that helped unblocked me!

For future reference I realized I misread the commands.

I needed terragrunt run-all plan for this to work correctly. Now my output is correct. I didn't realize I was nesting 2 layers of subcommands.

The other bit someone in sweetops slack community mentioned was deprecation of using tfvars.
Instead they said to use:

inputs = merge(
  # Configure Terragrunt to use common vars encoded as yaml to help you keep often-repeated variables (e.g., account ID)
  # DRY. We use yamldecode to merge the maps into the inputs, as opposed to using varfiles due to a restriction in
  # Terraform >=0.12 that all vars must be defined as variable blocks in modules. Terragrunt inputs are not affected by
  # this restriction.
  yamldecode(
    file("${find_in_parent_folders("region.yaml", "empty.yaml")}"),
  ),
  yamldecode(
    file("${find_in_parent_folders("env.yaml", "empty.yaml")}"),
  ),

due to the changes in the behavior that block the tfvars from being pulled in correctly, while yaml works fine in loading into TF inputs.

I'm still having a problem with it loading a parent file from a child, but will work from your example and see if I can get this to work then.

It worked this time from parent directory! Woot Woot. 🎉

Thanks again for the help.

Much better. Prefer to keep it terraform focused and not yaml. Will give that a try

You are welcome.

Maybe I should have one more episode about Terragrunt during Your Weekly Dose of Terraform. Who knows :)
