Stack Dependencies

`stack-dependencies` — Dependency wiring between units in stacks

A new stack-dependencies experiment enables the autoinclude block in terragrunt.stack.hcl files, allowing units and stacks to define dependency relationships and arbitrary configuration overrides during stack generation. This implements RFC #5663.

hcl

unit "vpc" {
  source = "../catalog/units/vpc"
  path   = "vpc"
}

unit "app" {
  source = "../catalog/units/app"
  path   = "app"

  autoinclude {
    dependency "vpc" {
      config_path = unit.vpc.path
    }

    inputs = {
      vpc_id = dependency.vpc.outputs.vpc_id
    }
  }
}

bash

terragrunt run --all --experiment stack-dependencies -- plan
