如何利用Route53 NS输出设置地形云子域NS？

Question

我在AWS Route53中创建了一个区域，如下所示

resource "aws_route53_zone" "my-app" {
  name = "${var.zone_name}"

}
data "aws_route53_zone" "selected" {
  name = "appgggghello.com."
}

output "ns" {
  value = "${data.aws_route53_zone.selected.name_servers}"
}

它将显示如下所示

ns = [
    ns-754.awsdns-350.net,
    ns-555.awsdns-0553.org,
    ns-555.awsdns-25552.co.uk,
    ns-45569.awsdns-55555.com
]

现在我要问的是，如何使用这个NS输出作为Cloudfalre的输入，就像这里

resource "cloudflare_record" "aws-ns-record" {
  domain = "${var.domain}"
  name   = "appgggghello.com"
  value = ["${data.aws_route53_zone.selected.name_servers}"]
  type     = "NS"
  priority = 1
}

在Route53中，我可以使用

records = ["${data.aws_route53_zone.selected.name_servers}"]

请告诉我怎样才能做到这一点？

Answer 1

cloudflare_record接受字符串作为值，而不是列表

value - (Optional) The (string) value of the record. Either this or data must be specified

所以我们需要在里面加上一个计数

现在我要问的是，如何使用这个NS输出作为Cloudfalre的输入，就像这里一样。然后根据计数从列表中提取元素。

resource "cloudflare_record" "aws-ns-record" {
  count = "${length(data.aws_route53_zone.selected.name_servers)}"
  domain = "${var.domain}"
  name   = "appgggghello.com"
  value = "${element(data.aws_route53_zone.selected.name_servers, count.index)}"
  type     = "NS"
  priority = 1
}
