amazon-web-services - 如何为数据源指定特定地域的ACM证书？

Question

我在两个区域为同一域颁发了 2 个证书，ap-northeast-1 和 us-east-1，因为我的主服务器位于 ap-northeast-1，而 CloudFront 需要 us-east-1 中的证书.

我想在 us-east-1 中选择一个作为 terraform 数据源，但它们具有相同的域名。

我像这样定义了证书资源

# ACM Certificate on us-east-1 (Global)
data "aws_acm_certificate" "cert_global" {
  domain = "my.example.com"
  statuses = ["ISSUED"]
}

我是这样调用它的

resource "aws_cloudfront_distribution" "static" {
  (snip)
  viewer_certificate {
    acm_certificate_arn = "${data.aws_acm_certificate.cert_global.arn}"
    minimum_protocol_version = "TLSv1"
    ssl_support_method = "sni-only"
  }
}

原因

1 error(s) occurred:

* aws_cloudfront_distribution.static: 1 error(s) occurred:

* aws_cloudfront_distribution.static: InvalidViewerCertificate: The specified SSL certificate doesn't exist, isn't in us-east-1 region, isn't valid, or doesn't include a valid certificate chain.
    status code: 400, request id: ceece17f-6610-11e7-977d-114d7e67d7c1

我知道 terraform 在两个区域检测到两个具有相同域名的证书，但不知道如何指定一个。

文档没有说明特定资源的区域 https://www.terraform.io/docs/providers/aws/d/acm_certificate.html

如何在 us-east-1 中使用一个？

Answer 1

我自己找到了答案。data 具有 provider 属性。

provider "aws" {
  alias = "virginia"
  region = "us-east-1"
}

data "aws_acm_certificate" "cert_global" {
  domain = "my.example.com"
  statuses = ["ISSUED"]
  provider = aws.virginia
}

在 us-east-1 中找到证书。
