使用新记录验证证书

Question

我正在尝试使用概述的here的方法在Terraform中验证ACM证书，基本上，这是使用Route53记录的DNS验证。据我了解，问题是它需要已经存在的Route53记录，以便它可以使用资源的records属性。但就我而言，这是一条新记录，因此，如果我同时尝试alias和records属性，例如

resource aws_route53_record wildcard {
  zone_id = var.environment.route53_zone.zone_id
  name    = "*.${local.cname}."
  type    = "A"
  alias {
    name                   = aws_cloudfront_distribution.main.domain_name
    zone_id                = aws_cloudfront_distribution.main.hosted_zone_id
    evaluate_target_health = false
  }
  records = [aws_acm_certificate.wildcard[0].domain_validation_options.0.resource_record_value]
}

我收到错误"alias" conflicts with "records"。在同一脚本中是否可以创建Route53记录并将其用于证书验证？

您需要使用aws_acm_certificate_validation资源，幸运的是，该页面提供了一个很好的示例，说明如何执行此操作。

resource "aws_acm_certificate" "cert" {
  domain_name       = "example.com"
  validation_method = "DNS"
}

data "aws_route53_zone" "zone" {
  name         = "example.com."
  private_zone = false
}

resource "aws_route53_record" "cert_validation" {
  name    = "${aws_acm_certificate.cert.domain_validation_options.0.resource_record_name}"
  type    = "${aws_acm_certificate.cert.domain_validation_options.0.resource_record_type}"
  zone_id = "${data.aws_route53_zone.zone.zone_id}"
  records = ["${aws_acm_certificate.cert.domain_validation_options.0.resource_record_value}"]
  ttl     = 60
}

resource "aws_acm_certificate_validation" "cert" {
  certificate_arn         = "${aws_acm_certificate.cert.arn}"
  validation_record_fqdns = ["${aws_route53_record.cert_validation.fqdn}"]
}

resource "aws_lb_listener" "front_end" {
  # [...]
  certificate_arn = "${aws_acm_certificate_validation.cert.certificate_arn}"
}
