Nested Regional Stacks

[hossko]

Hello,

I am trying to create a nested stacks with regional configuration,

here is my root dir:
.
├── config
│ ├── global.config.hcl
│ ├── us-central1.config.hcl
│ └── us-east1.config.hcl
├── root.hcl
├── terragrunt.stack.hcl
└── us-central1
└── terragrunt.stack.hcl

my root stack config:
#########################
locals {

Load all environment-specific configuration files

global_vars = read_terragrunt_config("config/global.config.hcl").locals
us_central1_vars = read_terragrunt_config("config/us-central1.config.hcl").locals
us_east1_vars = read_terragrunt_config("config/us-east1.config.hcl").locals
}

Global IAM Configuration

unit "iam" {
source = "${get_repo_root()}//units/iam"
path = "iam"

values = {
env = local.global_vars
}
}

US Central 1 Stack

stack "us-central1" {
source = "./us-central1"
path = "us-central1"

values = {
env = merge(local.global_vars, local.us_central1_vars)
}
}
##############################################

But when i execute "terragrunt stack generate", it create the us-central1 rendered config in 2 directories

.
├── config
│ ├── global.config.hcl
│ ├── us-central1.config.hcl
│ └── us-east1.config.hcl
├── root.hcl
├── terragrunt.stack.hcl
└── us-central1
└── terragrunt.stack.hcl

2 directories, 6 files
❯ tree -a -L 3
.
├── .terragrunt-stack
│ ├── iam
│ │ ├── .terragrunt-stack-manifest
│ │ ├── terragrunt.hcl
│ │ └── terragrunt.values.hcl
│ └── us-central1
│ ├── .terragrunt-stack
│ ├── .terragrunt-stack-manifest
│ ├── terragrunt.stack.hcl
│ └── terragrunt.values.hcl
├── config
│ ├── global.config.hcl
│ ├── us-central1.config.hcl
│ └── us-east1.config.hcl
├── root.hcl
├── terragrunt.stack.hcl
└── us-central1
├── .terragrunt-stack
│ └── networking
└── terragrunt.stack.hcl

Seems it is autodiscovering the us-central1 stack and treating it as a standalone, thus breaking input values and dependency path.

Any help please

Hey @hossko ,

This is a little hard to follow. Do you mind supplying some configurations that the community can fully copy + paste into their local workstations and some instructions on how to get the behavior you're looking for?

As a tip: If you use the ` character three times (```) with an hcl after it like the section below, code blocks will render a lot nicer:

```hcl
locals {
foo = "bar"
}
```

Becomes:

locals {
  foo = "bar"
}
