Route53のレコードをTerraformでimport

概要

もし手動でRoute53へレコードを追加していても、Terraformを使っている場合にimportでコード管理することが可能です。

手順

terraform準備

resource "aws_route53_record" "dev-example-com_acm-validate" {
  name    = "_xxxxxxxxxx.dev.example.com"
  type    = "CNAME"
  zone_id = aws_route53_zone.example-com.zone_id
  records = ["_XXXXX.acm-validations.aws"]
  ttl     = 300
}

実行の仕方

terraform import aws_route53_record.ここにterraformのリソース名 対象ドメインのゾーンID_レコード名_レコードタイプ（AとかCNAMEとかTXTとか）

import

❯ terraform import aws_route53_record.dev-example-com_acm-validate A12345XXX__xxxxxxxxxx.dev.example.com_CNAME
