Terraform --創建多個托管分區並為每個分區分配不同的記錄

Question

我是 terraform 的新手，正在嘗試更改現有腳本，我們用來創建 1 個 53 路區域和相應的 53 路記錄，現在的要求是再添加一個區域和 53 條記錄（相應地），我正在嘗試多級 map，我需要你的幫助來更正我的代碼

tf.vars
variable  "facade_hostname" = {
   type = "map"
   default = {
     old_mobile_facade_hostname = "xxx.morgen.nl" 
     new_mobile_facade_hostname = "xxx.test.nl" 
  }
}


dns_config = {

    old_dns_records  = {
      mobile_facade = {
        name    = "xxx.morgen.nl",
        ttl     = "5",
        type    = "A",
        records = [
          "1.2.3.4"]
      }
    },

    new_dns_records  = {
      mobile_facade = {
        name    = "xxx.test.nl",
        ttl     = "5",
        type    = "A",
        records = [
          "5.6.7.8"]
      }
    }

}

varibles.tf

variable "dns_config" {
  type    = map(object({
    name  = string
    ttl =   string
    type  = string
    records = string
  }))
  default = {}
}

variable "facade_hostname" {
  type    = map(object({
    old_mobile_facade_hostname  = string
    new_mobile_facade_hostname =   string
  }))
  default = {}
}

最后是我的資源創建

resource "aws_route53_zone" "private" {
  for_each = var.facade_hostname
  count = var.dns_config != "" && var.facade_hostname != "" ? 1 : 0
  name          = var.facade_hostname
  force_destroy = true
  vpc {
    vpc_id = module.vpc_private.vpc_id
  }
}

resource "aws_route53_record" "A" {
   for_each = var.facade_hostname
  count   = var.dns_config != "" && var.facade_hostname!= "" ? 1 : 0
  zone_id = aws_route53_zone.private[count.index].zone_id
  name    = var.dns_config.facade_hostname.name
  ttl     = var.dns_config.facade_hostname.ttl
  type    = var.dns_config.facade_hostname.type
  records = var.dns_config.facade_hostname.records

  allow_overwrite = true
}

運行 terraform init 時遇到的錯誤

最后，在花了一些時間之后，這似乎是一個可行的解決方案，以防它在未來對任何人有幫助，創建幾個托管區域並根據托管區域創建不同的 A 記錄，

resource "aws_route53_zone" "private" {
  for_each      = var.mobile_facade_hostname
  name          = each.key
  force_destroy = true
  vpc {
    vpc_id = module.vpc_private.vpc_id
  }
}

resource "aws_route53_record" "A" {
  for_each = aws_route53_zone.private
  zone_id  = each.value["zone_id"]
  name     = trimsuffix(each.value["name"], ".")
  type     = "A"
  ttl      = "5"
  records  = [var.mobile_facade_hostname[trimsuffix(each.value["name"], ".")]]

我的變量

mobile_facade_hostname  = { "x.y.nl" = "1.2.3.4", "a.b.nl" = "5.6.7.8" }

變量.tf

variable "mobile_facade_hostname" {
  type    = map(string)
  default = {}
}
