Terragrunt run does not create local file in mac OS

skumble commented 2 months ago

Describe the bug

When i run the terragrunt apply for the below terraform code it does not create the file "foo.bar" in the path "../modules/cassandra/instance_creation/files/" instead i could find it in inside the ".terragrunt-cache"

Steps To Reproduce

Steps to reproduce the behavior, code snippets and examples which can be used to reproduce the issue.

resource "local_file" "foo" {
  content  = "foo! test test test"
  filename = "${path.module}/../modules/cassandra/instance_creation/files/foo.bar"
}

Expected behavior

The "foo.bar" file should be created when the terragrunt apply command is run

Nice to haves

Hello, this is by design (if terraform.source is defined), in .terragrunt-cache is downloaded terraform sources, generated files if required, and invoked Terraform

Hello, thanks for the response.

Any alternative method to achieve this "resource "local_file"" in terragrunt ?

Hey @skumble , it depends on what you're trying to do.

One simple way to do this is to use the get_terragrunt_dir function to construct a file path, then pass that into your modules as a variable.

e.g.

# terragrunt.hcl
inputs = {
  filename = "${get_terragrunt_dir()}/foo.bar"
}

# main.tf
variable "filename" {}

resource "local_file" "this" {
  filename = var.filename
  content  = "foo! test test test"
}

Hi, can be used a couple of ideas:

can be passed path where to create files to module inputs
in simple cases, if terraform.source is not defined, then the working directory is the current dir so files will be created in the same location where terragrunt.hcl is located
can be used terraform hooks to copy result files after execution https://terragrunt.gruntwork.io/docs/features/hooks/
