Terraform 0.12迁移-具有默认对象的变量

Question

我试图将我的TF 0.11代码升级到0.12，但我遇到了一个变量问题。

在TF 0.11中，此块在variables.tf文件中按预期工作

variable "postgres_dbs" {
  type = "map"

  default = {
    postgres1 = {
      name_postfix = "postgres",
      enable      = true,
      sku         = "MO_Gen5_16",
      capacity    = "16"
    }
    postgres2 = {
      name_postfix = "postgres-2",
      enable      = false,
      sku         = "MO_Gen5_16",
      capacity    = "16"
    }
    postgres3 = {
      name_postfix = "postgres-3",
      enable      = false,
      sku         = "MO_Gen5_16",
      capacity    = "16"
    }
    postgres4 = {
      name_postfix = "postgres-4",
      enable       = false,
      sku          = "MO_Gen5_16",
      capacity     = "16"
    }
    postgres5 = {
      name_postfix = "postgres-5",
      enable       = false,
      sku          = "MO_Gen5_16",
      capacity     = "16"
    }
    postgres6 = {
      name_postfix = "postgres-6",
      enable       = false,
      sku          = "MO_Gen5_16",
      capacity     = "16"
    }
    postgres7 = {
      name_postfix = "postgres-7",
      enable       = false,
      sku          = "MO_Gen5_16",
      capacity     = "16"
    }
    postgres8 = {
      name_postfix = "postgres-8",
      enable       = false,
      sku          = "MO_Gen5_16",
      capacity     = "16"
    }
  }
}

在运行terraform 012upgrade命令(它完成时没有错误)之后，TF将块更改为use

variable "postgres_dbs" {
  type = map(string)

但是运行terraform validate时的错误是：

This default value is not compatible with the variable's type constraint:
element "postgres6": string required.

有什么建议吗？谢谢！

您可以更新和微调您的类型规范，如下所示：

type = map(object({
  name_postfix = string
  enable       = bool
  sku          = string
  capacity     = string
}))

理想情况下，您可以将capacity对象参数指定为number，但是您将该参数的输入转换为string，因此这将导致不兼容，除非您将输入指定为其自然的number类型。
