如何在terraform中解密windows管理员密码？

Question

我正在配置单个Windows服务器,以便在AWS中使用terraform进行测试.每次我需要用我的PEM文件解密我的Windows密码才能连接.相反,我选择了terraform参数get_password_data并将其存储password_data在tfstate文件中.现在我如何使用插值语法解密相同的内容rsadecrypt

请找到我的以下terraform代码

### Resource for EC2 instance creation ###

resource "aws_instance" "ec2" {
  ami                   =   "${var.ami}"
  instance_type         =   "${var.instance_type}"
  key_name              =   "${var.key_name}"
  subnet_id             =   "${var.subnet_id}"
  security_groups       =  ["${var.security_groups}"]
  availability_zone     =   "${var.availability_zone}"
  private_ip            =   "x.x.x.x"
  get_password_data     =   "true"

  connection {
    password            =   "${rsadecrypt(self.password_data)}"
    }

  root_block_device {
              volume_type = "${var.volume_type}"
              volume_size = "${var.volume_size}"
    delete_on_termination = "true"
    }

  tags {
        "Cost Center"  =  "R1"
        "Name"         =  "AD-test"
        "Purpose"      =  "Task"
        "Server Name"  =  "Active Directory"
        "SME Name"     =  "Ravi"
    }

}


output "instance_id" {
  value = "${aws_instance.ec2.id}"
}


### Resource for EBS volume creation ###

  resource "aws_ebs_volume" "additional_vol" {
    availability_zone =  "${var.availability_zone}"
    size              =  "${var.size}"
    type              =  "${var.type}"
}

### Output of Volume ID ###

  output "vol_id" {
    value = "${aws_ebs_volume.additional_vol.id}"
}

### Resource for Volume attachment ###

   resource "aws_volume_attachment" "attach_vol" {
     device_name       = "${var.device_name}"
     volume_id         = "${aws_ebs_volume.additional_vol.id}"
     instance_id       = "${aws_instance.ec2.id}"
     skip_destroy      = "true"
}

使用启动实例时指定的key_pair对密码进行加密，您仍然需要使用它来解密，因为password_data仍然只有base64编码的加密密码数据。

你应该用 ${rsadecrypt(self.password_data,file("/path/to/private_key.pem"))}

这是有充分理由的。您真的不希望只是base64编码的密码在状态中浮动。

简短版本：您缺少插值函数中的第二个参数。
