Terragrunt provider.tf 生成不生成文件

Question

预期当从根目录运行terragrunt run-all apply 时，将在子目录中创建一个provider.tf 文件。我已经验证我的后端能够与我的 azure 存储帐户通信，并且它会在那里创建一个 terraform.tfstate 文件。我希望provider.tf 文件出现在每个“service#”文件夹下。我对terragrunt非常陌生。这是我第一次练习它。我实际上并没有尝试部署任何 terraform 资源。只需在我的子目录中创建 provider.tf 文件。 TF版本是1.1.5。 Terragrunt 版本是 0.36.1。

我的文件夹结构

    container_name       = local.env_vars.container_name 
    key            = "${path_relative_to_include()}/terraform.tfstate"
  }
}


# Collect values from environment_vars.yaml and set as local variables
locals {
  env_vars = yamldecode(file("environment_vars.yaml"))
}

environment_vars.yaml配置

resource_group_name:  "my-tf-test"
storage_account_name: "mystorage"
container_name:       "tfstate"

terragrunt.hcl 服务#文件夹中的配置

# Collect values from parent environment_vars.yaml file and set as local variables
locals {
  env_vars = yamldecode(file(find_in_parent_folders("environment_vars.yaml")))
}

# Include all settings from the root terragrunt.hcl file
include {
  path = find_in_parent_folders()
}

当我运行 terragrunt run-all 时，这是输出

看起来很成功，但是没有 provider.tf 文件出现在任何目录中。甚至没有根。它只是在 service# 目录下创建一个 terraform.tfstate 文件。

但是...如果我从根目录运行terragrunt init，它将按预期在根目录中创建provider.tf 文件。尽管 terragrunt init 成功，但这在 service# 目录中不起作用。

我错过了什么？这是最基本的 terragrunt 用例，但这些示例让我相信这应该可以正常工作。

我让它工作了，但是 terragrunt run-all apply 命令根本不起作用。相反，我必须在根目录运行 terragrunt apply。如果您不在根目录，则所有子文件夹都会组合在一起，而不是放在 dev/prod 子文件夹中。然后我必须去每个子文件夹并再次运行它。这是我让它工作的唯一方法。
