Terraform 0.11-模拟循环

如何解决Terraform 0.11-模拟循环

我有Terraform 0.11.14 ，并努力模拟Terraform 0.12的for循环。

我想解密AWS EC2 Windows实例密码并将其放在terraform输出中。为此，我需要：

• 获取EC2实例密钥文件名列表
• 构建密钥文件路径列表
• 获取EC2实例的列表password_data
• 对于每个EC2实例password_data，使用各自的密钥文件运行解密

main.tf

resource "aws_instance" "this" {
  count = "${var.can_create ? (var.instance_count > 1 ? var.instance_count : 1) : 0}"
  get_password_data = "${var.get_password_data}"
  ...
}

variables.tf

variable "can_create" {
  description = "If false,instance is not going to be created"
  type        = "string"
  default     = "true"
}
variable "instance_count" {
  description = "Number of instances to launch"
  default     = 1
}
variable "get_password_data" {
  description = "If true,wait to retrieve password for Windows instances"
  default     = "true"
}
...

output.tf

locals {
  this_key_name      = "${aws_instance.this.*.key_name}"
  this_key_path      = "${formatlist("/root/.ssh/%s",local.this_key_name)}"
  this_password_data = [for p in local.this_key_path : rsadecrypt(aws_instance.this.*.password_data,file(p))] #this does not work
}

output "password_data" {
  description = "List of passwords for Windows instances"
  value       = ["${local.this_password_data}"]
}

特别是如何模拟this_password_data变量中的循环？
