Checking domain rights

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. View a description of the command:

   yc certificate-manager certificate get --help
   

2. Run this command:

   yc certificate-manager certificate get \
     --id fpq6gvvm6piu******** \
     --full
   

   Where:

   • --id: Certificate ID.
   • --full: Show a list of active domain rights checks.

   Result:

   id: fpq6gvvm6piu********
   folder_id: b1g7gvsi89m3********
   created_at: "2020-09-15T08:49:11.533771Z"
   name: mymanagedcert
   type: MANAGED
   domains:
   - example.com
   status: VALIDATING
   updated_at: "2020-09-15T08:49:11.533771Z"
   challenges:
   - domain: example.com
     type: HTTP
     created_at: "2020-09-15T08:49:11.533771Z"
     updated_at: "2020-09-15T08:51:44.991065Z"
     status: PENDING
     message: Create a file in your web server's base directory.
     http_challenge:
       url: http://example.com/.well-known/acme-challenge/3LiH-nrTC7GdMbRgVqttEvdTODeNeaD0TtX********
          content: 3LiH-nrTC7GdMbRgVqttEvdTODeNeaD0TtXteWgtAH8.ZHCju15sJiKBwT8G5FTl7UtfmJWp1gKNYYP********
   

3. You can find the info you will need to pass the rights check under http_challenge.

4. As soon as the domain rights check is passed, the check status will change to Valid:

   yc certificate-manager certificate get \
     --id fpq6gvvm6piu******** \
     --full
   

   Result:

   ...
   domains:
   - example.com
   status: VALID
   ...
   

5. After the check status for all the domains changes to Valid, the certificate will be issued and its status will change to Issued:

   yc certificate-manager certificate get \
     --id fpq6gvvm6piu******** \
     --full
   

   Result:

   ...
   domains:
   - example.com
   status: ISSUED
   ...
   

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

For more information about the provider resources, see the documentation on the Terraform website or the mirror.

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

With Terraform, you can create a DNS record required to check your rights to a domain. To do this:

1. In the Terraform configuration file, describe the parameters of the resources you want to create:

   resource "yandex_cm_certificate" "le-certificate" {
     name    = "<certificate_name>"
     domains = ["<domain>"]
   
     managed {
     challenge_type = "DNS_CNAME"
     }
   }
   
   resource "yandex_dns_recordset" "validation-record" {
     zone_id = "<zone_ID>"
     name    = yandex_cm_certificate.le-certificate.challenges[0].dns_name
     type    = yandex_cm_certificate.le-certificate.challenges[0].dns_type
     data    = [yandex_cm_certificate.le-certificate.challenges[0].dns_value]
     ttl     = <record_time_to_live_in_seconds>
   }
   
   data "yandex_cm_certificate" "example" {
     depends_on      = [yandex_dns_recordset.validation-record]
     certificate_id  = yandex_cm_certificate.le-certificate.id
     wait_validation = true
   }
   
   # Use data.yandex_cm_certificate.example.id to get a valid certificate.
   
   output "cert-id" {
     description = "Certificate ID"
     value       = data.yandex_cm_certificate.example.id
   }
   

   Where:

   • yandex_cm_certificate resource parameters:
     • domains: Domain you need to create a certificate for.
     • challenge_type: Domain owner verification method. The possible values are:
       • DNS_CNAME: Create a DNS record in CNAME format with the specified value. This method is recommended for automatic certificate renewal.
       • DNS_TXT: Create a DNS record in TXT format with the specified value.
   • yandex_dns_recordset resource parameters:
     • zone_id: ID of the DNS zone the owner verification record will be in.
     • name: Record name.
     • type: DNS record type.
     • data: Record value.
     • ttl: Record time to live (TTL) in seconds before updating the record value.
   • yandex_dns_recordset data source parameters:
     • depends_on: Indicates dependence on another Terraform resource.
     • certificate_id: Certificate ID.
     • wait_validation: Certificate validation wait flag. If true, the operation will not be completed until the certificate is in VALIDATING status. The default value is false.

   For more information about resource parameters, see the Terraform provider documentation.

2. Create resources:

   1. In the terminal, change to the folder where you edited the configuration file.

   2. Make sure the configuration file is correct using the command:

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

This will create a certificate and DNS record in the specified folder. You can check the new certificate and its settings using the management console or this CLI command:

yc certificate-manager certificate get <certificate_name> --full

To get the information required to pass the permission check for a domain, use the get REST API method for the Certificate resource or the CertificateService/Get gRPC API call with the view=FULL flag.
