What is the proper way to ignore the root directory in terragrunt

[yordis]

Hey folks, I am running terragrunt run-all * from the ./terraform where I do not have a backend.tf because I removed it.

├── README.md
└── terraform
    ├── Makefile
    ├── digitalocean
    │   └── businessname
    │       └── genesis
    │           ├── backend.tf
    │           ├── main.tf
    │           ├── provider.tf
    │           └── terragrunt.hcl
    └── terragrunt.hcl

I intend that ./terraform isn't any project but just the following:

remote_state {
  backend  = "s3"
  generate = {
    path      = "backend.tf"
    if_exists = "skip"
  }
  config = {
    skip_metadata_api_check     = true
    skip_credentials_validation = true
    endpoint                    = "nyc3.digitaloceanspaces.com"
    region                      = "us-east-1"
    bucket                      = "..."
    key                         = "${path_relative_to_include()}/terraform.tfstate"
  }
  disable_init = true
}

But I keep getting the following error:

time=2023-09-26T03:43:30Z level=error msg=1 error occurred:
	* [/home/runner/work/tf-infra/tf-infra/terraform] exit status 1

What is the proper way to say that such a top-level isn't a project and ignore it?

Read https://terragrunt.gruntwork.io/docs/reference/config-blocks-and-attributes/#skip and add the following to ./terraform/terragrunt.hcl or any file you would like to skip the project setup:

# ./terraform/terragrunt.hcl

# notice here!
skip = true

remote_state {
  backend  = "s3"
  generate = {
    path      = "backend.tf"
    if_exists = "skip"
  }
  config = {
    skip_metadata_api_check     = true
    skip_credentials_validation = true
    endpoint                    = "nyc3.digitaloceanspaces.com"
    region                      = "us-east-1"
    bucket                      = "..."
    key                         = "${path_relative_to_include()}/terraform.tfstate"
  }
  disable_init = true
}
