如何找出在这个地形代码中使用的属性?

就地形文件达成一致可能会更好。我确实发现你需要参考 aws_iam_instance_profile 而不是 aws_iam_role 这里是指向doc的链接- https://www.terraform.io/docs/providers/aws/r/iam_instance_profile.html .

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"
....
}

正在从上面共享的链接复制实例配置文件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
}
