download_dir

unitoptional(string, "…")

Usage

The download_dir attribute sets the directory Terragrunt downloads OpenTofu/Terraform modules into. By default, Terragrunt creates a .terragrunt-cache directory next to the unit’s terragrunt.hcl:

• Directoryapp

  • terragrunt.hcl
  • Directory.terragrunt-cache/

    • …

Precedence

Terragrunt uses the first of these that is set:

1. The --download-dir flag.
2. The TG_DOWNLOAD_DIR environment variable.
3. download_dir in the unit’s terragrunt.hcl.
4. download_dir in a file the unit includes.

Defaults to .terragrunt-cache.

Examples

root.hcl

download_dir = "/tmp/terragrunt/${path_relative_to_include()}"
