Terraform 多个 AWS route53 MX 记录

Question

我在 tf 中有 locals 可以将 MX 记录推送到 cloudflare，它的工作原理正是我想要的。我想对 Route53 使用相同的 locals，但对于 route53，records 应该合并为一个。我如何使用 blow locals 使用 terraform 推送到 Route53。

locals {
    MXRecordSets = [
         {
            Name =  "example.com.",
            Type =  "MX",
            TTL =  3600,
            MXRecords =  [
                {
                    "Value" =  "1 aspmx.l.google.com"
                },
                {
                     "Value" =  "5 alt1.aspmx.l.google.com"
                 }
            ]
        }
    ]
}
locals {
    FlatMXRecordSets = merge([
    for idx, MXRecordSet in local.MXRecordSets:
      {
        for MXRecord in MXRecordSet.MXRecords:
            "${idx}-${MXRecord.Value}" => {
              MXRecordSet = MXRecordSet
              MXRecord =  MXRecord["Value"]
          }
      }
    ]...)
}

最后我使用下面的 aws route53 模块将更改推送到 AWS，但它不起作用：

resource "aws_route53_record" "mx_records" {
  for_each =local.FlatMXRecordSets
  zone_id  = aws_route53_zone.carfeine_com.id
  name     = each.value["MXRecordSet"].Name
  type     = each.value["MXRecordSet"].Type
  records  = [ each.value["MXRecord"] ]
  ttl      = 1
}

错误是 [Tried to create resource record set [name='example.com.', type='MX'] but it already exists] 因为我正在使用 for_each 而我不应该使用它。还有其他方法吗？

你的MXRecordSets已经是平的了，所以不需要压平。但它也是一个地图列表，这可能会导致更多问题，因为列表取决于项目的顺序。因此，如果可能的话，最好只使用地图中的地图：

locals {
    MXRecordSets = {
       "mail.mwotest.xyz." = {
            Type =  "MX",
            TTL =  3600,
            MXRecords =  [
                {
                    "Value" =  "1 aspmx.l.google.com"
                },
                {
                     "Value" =  "5 alt1.aspmx.l.google.com"
                 }
            ]
        }
    }            
}

然后

resource "aws_route53_record" "mx_records" {
  for_each = local.MXRecordSets
  zone_id  = aws_route53_zone.carfeine_com.id
  name     = each.key
  type     = each.value.Type
  records  = [ for key,record in each.value["MXRecords"]: record["Value"] ]
  ttl      = 1
}

在上面，

 [ for key,record in each.value["MXRecords"]: record["Value"] ]

将为 MX 生成正确的 records 作为：

records = ["1 aspmx.l.google.com", "5 alt1.aspmx.l.google.com"]
