# Google Cloud Unit Folders Module
This module allows creation and management of an organizational hierarchy "unit" composed of a parent folder (usually mapped to a business unit or team), and a set of child folders (usually mapped to environments) each with a corresponding set of service accounts, IAM bindings and GCS buckets.
## Example
```hcl
module "folders-unit" {
source = "./modules/folders-unit"
name = "Business Intelligence"
short_name = "bi"
automation_project_id = "automation-project-394yr923811"
billing_account_id = "015617-16GHBC-AF02D9"
organization_id = "506128240800"
root_node = "folders/93469270123701"
prefix = "unique-prefix"
environments = {
dev = "Development",
test = "Testing",
prod = "Production"
}
service_account_keys = true
}
```
