Terraform 无法从远程状态读取

Terraform cannot read from remote state

Terraform 版本

v0.12.1

AWS 提供商版本

v2.16.0

我已经配置了 Terraform 工作区,目前我的工作区指向 dev,其中我有一个用于我的 VPC 和子网的 tfstate 文件,还有一个用于我的安全组的 tfstate 文件,但是当我'我试图将 vpc_id 从我的 vpc 远程 tfstate 引用到我的安全组然后我收到以下错误消息

No stored state was found for the given workspace in the given backend.

我的 s3 存储桶如下所示

nonprod-us-east-1
  |-- env
         |-- dev
                |-- vpc_subnet/tfstate
                |-- security_group/tfstate

Terraform 配置文件

安全组 tf 配置
terraform {
    backend "s3"{
        # Configuration will be injected by environment variables.
    }
}

provider "aws" {
  region = "${var.region}"
}


data "terraform_remote_state" "vpc_subnet" {
  backend = "s3"

  config = {
    bucket  = "nonprod-us-east-1"
    key     = "vpc_subnet/tfstate"
    region  = "us-east-1"
  }
}

 vpc_id = "${data.terraform_remote_state.vpc_subnet.outputs.vpc_id}"

并且我已验证我的 vpc_subnet/tfstate 输出有 vpc_id

VPC 子网 tf 状态的输出

预期行为

它应该能够从远程 tf 状态位置读取 vpc_id

实际行为

无法从远程 tf 状态读取输出

终于解决了,原来是 bucket key 的问题,因为我使用的是 Terraform workspace,所以 tfstate 文件是在文件夹 env:/dev/vpc_subnet/tfstate 下创建的,在更正 bucket key 之后,它能够解析 tfstate 文件。
