Cause

When you use alicloud_cdn_domain_new to create a CDN-accelerated domain name and add an HTTPS certificate, you set the cert_type parameter to cas, indicating the use of a certificate from Alibaba Cloud Certificate Center.

If you set the cert_type parameter to cas and your account is created on the Alibaba Cloud international site, you must set the cert_region parameter to ap-southeast-1. If your account is created on the Alibaba Cloud China site, this setting is not required as the cert_region parameter defaults to cn-hangzhou, which is the region of Alibaba Cloud Certificate Center for the China site.

For more information about the parameters of alicloud_cdn_domain_new, see alicloud_cdn_domain_new.

Solution

When you use alicloud_cdn_domain_new to create a CDN-accelerated domain name and add an HTTPS certificate, set the cert_type parameter to cas:

  • If your account is created on the international site, set the cert_region parameter to ap-southeast-1.

  • If your account is created on the China site, the cert_region parameter defaults to cn-hangzhou.

Sample code:

# Add an accelerated domain name.
resource "alicloud_cdn_domain_new" "domain" {
  domain_name = "mycdndomain.alicloud-provider.cn"
  cdn_type    = "download"
  scope       = "overseas"
  sources {
    content  = "myoss.oss-rg-china-mainland.aliyuncs.com"
    type     = "oss"
    priority = "20"
    port     = 80
    weight   = "15"
  }
  # Configure a certificate.
  # cert_id: To obtain a certificate ID, you must first purchase or upload a certificate in Alibaba Cloud Certificate Center.
  # cert_type="cas" indicates that a certificate from Alibaba Cloud Certificate Center is used.
  # cert_region = "ap-southeast-1" indicates that Alibaba Cloud Certificate Center for the international site is used.
  certificate_config {
    cert_id    = "1111111"
    cert_name  = "cert-2987438279834"
    cert_type  = "cas"
    cert_region = "ap-southeast-1"
  }
}
