How Has This Been Tested?

• I have tested and validated these changes using this example

module "docker_image" {
  source = "../../modules/docker-build"

  create_ecr_repo = false
  ecr_address     = "XXXXXXXX.dkr.ecr.eu-central-1.amazonaws.com"
  ecr_repo        = random_pet.this.id
  image_tag       = "1.0"
  source_path     = "context"
  build_args = {
    FOO = "bar"
  }
}
