Must repeat local blocks in terragrunt.hcl

[jmcgeheeiv]

Thank you for Terragrunt. It is a fine tool.

It seems to me that local variable definitions are not so DRY. For example, in the sample presented here, the reading of env.hcl and the extraction of variable env is repeated in prod/us-east-1/prod/mysql/terragrunt.hcl and non-prod/us-east-1/qa/webserver-cluster/terragrunt.hcl:

locals {
  # Automatically load environment-level variables
  environment_vars = read_terragrunt_config(find_in_parent_folders("env.hcl"))

  # Extract out common variables for reuse
  env = local.environment_vars.locals.environment
}

Is there no way to put this in the root terragrunt.hcl so that all configurations can reference a single definition of local.env?

Unfortunately we don't yet have a feature to do this. We have a design for something that makes this possible (see https://github.com/gruntwork-io/terragrunt/blob/master/_docs/rfc/imports.md), but we haven't implemented it yet.

The well-written RFC you cite shows Gruntworks are obviously well aware of the situation. Therefore I will close this issue in deference to the RFC.

@yorinasub17 There are good news? would be possible to implement it? Thanks for all
