Help with set variables via gitlab-ci

[masbolgankezderim]

Describe the bug I cannot set variables via gitlab-ci

deploy:
  stage: deploy-test
  image: 
    name: alpine/terragrunt:1.8.1
  before_script:
    - terragrunt plan -var="function_name=${PROJECT_NAME}" -var="image_uri=123456789.dkr.ecr.${ECR_REGION}.amazonaws.com/${CI_PROJECT_NAME}:${PROJECT_NAME}-${CI_COMMIT_SHORT_SHA}"
  script:
    - terragrunt apply -var="function_name=${PROJECT_NAME}" -var="image_uri=123456789.dkr.ecr.${ECR_REGION}.amazonaws.com/${CI_PROJECT_NAME}:${PROJECT_NAME}-${CI_COMMIT_SHORT_SHA}" --auto-approve

terragrunt.hcl

include "root" {
  path = find_in_parent_folders()
}

terraform {
  source = "https://github.com/terraform-aws-modules/terraform-aws-lambda.git"
}

inputs = {
  function_name   = "var.function_name"
  description     = "My awesome lambda function 5555555"
  create_package  = false
  image_uri       = "var.image_uri"
  package_type    = "Image"
}

terragrunt.hcl in root folder

remote_state {
  backend = "s3"
  generate = {
    path      = "backend.tf"
    if_exists = "overwrite"
  }
  config = {
    bucket         = "test-bucket"
    key            = "${path_relative_to_include()}/terraform.tfstate"
    region         = "eu-north-1"
    encrypt        = true
  }
}

Nice to have

  function_name   = "var.function_name"
  description     = "My awesome lambda function 5555555"
  create_package  = false
  image_uri       = "var.image_uri"

var.function_name and var.image_uri are never called, since they are wrapped in double quotes and thus, handled as string.

I think the following should work:

  function_name   = var.function_name
  description     = "My awesome lambda function 5555555"
  create_package  = false
  image_uri       = var.image_uri

Hi, also, variables can be set through env variables TF_name
