Support for updating local modules when using Terragrunt

[Taiki130]

Feature Overview

Currently, the system supports updating local modules when using Terraform, but it does not support updating local modules when using Terragrunt.

Why is the feature needed?

When updating local modules in Terragrunt, the changes are not detected, and the plan is not triggered.

Example Code

No response

Note

Alternatively, enabling the ability to configure dependencies on directories or files related to the target could provide a viable alternative solution.

tfaction-root.yaml

  - working_directory: foo/bar
    target: foo/bar
    extra_dependencies:
      - modules

Thank you for reporting the issue.
I'll try to reproduce the issue.

I think this issue is related.

I see.

tfaction uses terraform-config-inspect to detect dependencies.

https://suzuki-shunsuke.github.io/tfaction/docs/feature/local-path-module/

But this tool can't resolve dependencies defined by Terragrunt.

terragrunt.hcl

terraform {
  source = "../module"
}

terraform-config-inspect --json terragrunt

Output:

  "path": "terragrunt",
  "variables": {},
  "outputs": {},

  "data_resources": {},
