Question

在我的某个项目中遇到Terraform远程状态问题。状态文件在S3中是远程的。我是这样导入的：

data "terraform_remote_state" "management" {
  backend = "s3"

  config {
    bucket = "testbucket"
    key    = "subfolder/terraform.tfstate"
    region = "us-west-2"
  }
}

我可以在上面的statefile的根级别看到输出：

            "outputs": {
            "cidr": {
                "sensitive": false,
                "type": "string",
                "value": "10.90.0.0/16"
            },

我正在使用远程状态：

module "dev-alpha-application" {
  source          = "../../modules/application"
  envname         = "test-app"
  baseami         = "ami-a042f4d8"
  key_name        = "pb-smarsh-test"
  clui_baseami    = "ami-xxxxxxxx"
  adui_baseami    = "ami-xxxxxxxx"
  cidr            = "10.80.0.0/16"
  management_cidr = "${data.terraform_remote_state.management.cidr}"

  vpn_gateway_id = "cgw-xxxxxxxx"

  cidrs = "${list("${data.terraform_remote_state.management.cidr}", "${module.dev-alpha-application.cidr}")}"

除非我忽略了一些愚蠢的东西，否则这应该有效，但是当我运行terraform时，我会收到以下错误：

* module.dev-alpha-application.var.management_cidr: Resource 'data.terraform_remote_state.management' does not have attribute 'cidr' for variable 'data.terraform_remote_state.management.cidr'

Terraform init按预期工作。任何帮助将不胜感激。我试图尽可能多地包含信息

编辑 - 在调试模式下，它似乎正在打开远程状态文件ok

但我也在调试日志中看到了这一点：

Answer 1

对于那些有类似问题的人。这主要是因为terraform的文档不是最新的。对于terraform <= 0.11，您需要直接不使用“输出”直接访问输出变量，例如data.terraform_remote_state.management.cidr。

使用> = 0.12，它将使用“输出”，例如data.terraform_remote_state.management.outputs.cidr。

该网站上的文档也将被修复，但目前尚未部署。

请参见以下示例-通常需要一个dynamodb锁定表，以便您可以与团队成员共享状态而不会破坏状态。

data "terraform_remote_state" "buckets" {
  backend     = "s3"
  environment = "default"
  config {
    bucket         = "state-bucket"
    dynamodb_table = "dynamodbtable-tfstate"
    key            = "aws/buckets/tfstate/terraform.tfstate"
    region         = "${var.region}"
  }
}

资源没有变量属性 - Terraform远程状态
