Terraform 任何真实情况

Question

我有一个在 *.tfvars 中指定的实例类型变量，我正在尝试合并“anytrue”function 的使用，但是我无法让它工作。 目的是为用户提供四种实例类型的选择，并且它们是唯一被接受的实例类型

variables.tf
variable "myinstance" {
    type = list(string)
    description "Select one of the following instance types - t3.medium, t3.large, t3.xlarge 
                 or t3.2xlarge"
    validation {
        condition = anytrue (["t3.medium","t3.large","t3.xlarge","t3.2xlarge"],var.myinstance)
        error_message = "Please select a valid instance type."
    }
    default = []
  }

*.tfvars 文件 = ["t3.medium"]

错误信息：

     var.myinstance will be known only after apply.

     Function "anytrue" expects only 1 argument(s)

我认为最好的方法是使用setintersection ：

 condition = length(setintersection(["t3.medium","t3.large","t3.xlarge","t3.2xlarge"], var.myinstance)) >= length(var.myinstance)
