Terraform:如何在基于条件的模块中设置变量？

variable "enable_module" {
  type    = bool
  default = false
}

module "conditional_module" {
  source = "./modules/conditional_module"

  # 通过条件语句设置变量值
  var1 = var.enable_module ? "value1" : "value2"
  var2 = var.enable_module ? "value3" : "value4"
}

variable "var1" {
  type = string
}

variable "var2" {
  type = string
}

resource "aws_instance" "example" {
  # 使用变量 var1 和 var2
  ami           = var.var1
  instance_type = var.var2
}
