Description

Currently google_certificate_manager_dns_authorization is supported as a resource, but not a data source.

In some cases one may wish to manage DNS and Certificates in separate terraform configurations (e.g. when the DNS is managed by a third party service external to Google Cloud). In these situations it would be useful to be able to create the DNS authorization resource in one configuration and reference it in another configuration to retrieve the value of dns_resource_record.

New or Affected Resource(s)

• google_certificate_manager_dns_authorization

Potential Terraform Configuration

Certificate configuration:

resource "google_certificate_manager_dns_authorization" "example" {
  name        = "example-dns-auth"
  description = "example dns"
  domain      = "example.com"
}

resource "google_certificate_manager_certificate_map" "example" {
  name        = "example-cert-map"
  description = "example certificate map"
}

resource "google_certificate_manager_certificate" "example" {
  name        = "example-cert"
  description = "example cert"
  managed {
    domains = [
      join(".",["*",google_certificate_manager_dns_authorization.example.domain]),
    ]
    dns_authorizations = [
      google_certificate_manager_dns_authorization.example.id,
    ]
  }
}

resource "google_certificate_manager_certificate_map_entry" "example" {
  name        = "example-cert-map-entry"
  description = "example certificate map entry"
  map = google_certificate_manager_certificate_map.example.name 
  certificates = [google_certificate_manager_certificate.example.id]
  hostname = "*.example.com"
}

Separate DNS configuration:

data "google_certificate_manager_dns_authorization" "example" {
  name        = "example-dns-auth"
}

resource "cloudflare_record" "example_caa_gc_certman" {
  count   = 1
  zone_id = data.cloudflare_zone.example.id
  name    = split(".", google_certificate_manager_dns_authorization.example.dns_resource_record.0.name).0
  type    = google_certificate_manager_dns_authorization.example.dns_resource_record.0.type
  ttl     = 360
  content   = google_certificate_manager_dns_authorization.example.dns_resource_record.0.data
}
