Question

运行terraform plan时出现此错误：

错误：加载/Users/antkong/infrastructure/windows-server/main.tf时出错：读取时出错 aws_instance [worker]的配置：aws_iam_role.windows_server_role：资源变量必须分为三个部分：TYPE.NAME.ATTR，位于：

这是相关代码

resource "aws_instance" "worker" {
  ami                  = "${data.aws_ami.windows_server.image_id}"
  instance_type        = "${var.instance}"
  iam_instance_profile = "${aws_iam_role.windows_server_role}"  // <- ERROR here
  get_password_data    = "true"

我认为可以修复它，我可以使用

iam_instance_profile = "${aws_iam_role.windows_server_role.id}"

或

iam_instance_profile = "${aws_iam_role.windows_server_role.arn}"

但是在文档中并不明显。

除了在运行时遇到错误外，如何找到它？

在terraform文档中达成一致可能会更好。我确实发现您需要引用aws_iam_instance_profile而不是aws_iam_role。这是doc-https://www.terraform.io/docs/providers/aws/r/iam_instance_profile.html的链接。

代码看起来像

resource "aws_instance" "worker" {
  ami                  = "${data.aws_ami.windows_server.image_id}"
  instance_type        = "${var.instance}"
  iam_instance_profile = "${aws_iam_instance_profile.windows_server.name}"
  get_password_data    = "true"
....
}

从上面共享的链接中复制实例配置文件def：

resource "aws_iam_instance_profile" "windows_server" {
  name = "windows_server_instance_profile"
  role = "${aws_iam_role.windows_server.name}"
}

resource "aws_iam_role" "windows_server" {
  name = "windows_server_role"
  path = "/"

  assume_role_policy = <<EOF
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": "sts:AssumeRole",
            "Principal": {
               "Service": "ec2.amazonaws.com"
            },
            "Effect": "Allow",
            "Sid": ""
        }
    ]
}
EOF
}

如何找出在此Terraform代码中使用哪个属性？
