terraform_remote_state 数据块语法

Question

我正在使用 Terraform 进行 AWS 多账户设置。我有一个创建多个子账户的主账户，在子账户中我引用主账户的远程状态来检索输出值。

测试中此配置的 terraform plan 命令失败 main.tf:

terraform {
  required_version = ">= 0.12.0"

  backend "s3" {
    bucket = "bucketname"
    key    = "statekey.tfstate"
    region = "us-east-1"
  }
}

provider "aws" {
  region  = "us-east-1"
  version = "~> 2.7"
}

data "aws_region" "current" {}

data "terraform_remote_state" "common" {
  backend = "s3"
  config {
        bucket = "anotherbucket"
        key    = "master.tfstate"
  }
}

出现以下错误：

➜  test terraform plan

Error: Unsupported block type

  on main.tf line 20, in data "terraform_remote_state" "common":
  20:   config {

Blocks of type "config" are not expected here. Did you mean to define argument
"config"? If so, use the equals sign to assign it a value.

从 the documentation 可以看出，这应该有效……我做错了什么？

➜  test terraform -v  
Terraform v0.12.2
+ provider.aws v2.14.0

似乎 related document 在升级到 0 后没有更新。12.x

作为错误提示，在config

后添加=


data "terraform_remote_state" "common" {
  backend = "s3"
  config = {
        bucket = "anotherbucket"
        key    = "master.tfstate"
  }
}

如果问题解决了，建议提个PR来更新文档，这样其他人就可以避免同样的问题了。
