Creating a resource record

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.

Run this command:

yc dns zone add-records --name <DNS_zone_name> \
  --record "<domain_name> <TTL> <record_type> <value>"

Example

Creating a TXT record with a DKIM signature:

yc dns zone add-records test-zone \
  --record "test-record TXT v=DKIM1;k=rsa;p=MIIBIjAN...gkH2v1NTgQdTKfPmDK...YdRiwIDAQAB"

If your TXT record contains multiple values, enclose each one in double quotes (""):

yc dns zone add-records test-zone \
  --record "test-record TXT v=DKIM1;k=rsa;p=MIIBIjAN""gkH2v1NTgQdTKfPmDK""YdRiwIDAQAB"

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

1. In the configuration file, describe the parameters of resources that you want to create: You can add multiple records at the same time.

   resource "yandex_vpc_network" "foo" {}
   
   resource "yandex_dns_zone" "zone1" {
     name        = "my-private-zone"
     description = "desc"
   
     labels = {
       label1 = "label-1-value"
     }
   
     zone             = "example.com."
     public           = false
     private_networks = [yandex_vpc_network.foo.id]
   }
   
   resource "yandex_dns_recordset" "rs1" {
     zone_id = yandex_dns_zone.zone1.id
     name    = "srv.example.com."
     type    = "A"
     ttl     = 200
     data    = ["10.1.0.1"]
   }
   
   resource "yandex_dns_recordset" "rs2" {
     zone_id = yandex_dns_zone.zone1.id
     name    = "srv2"
     type    = "A"
     ttl     = 200
     data    = ["10.1.0.2"]
   }
   
   resource "yandex_dns_recordset" "rs_dkim" {
     zone_id = yandex_dns_zone.zone1.id
     name    = "dkim"
     type    = "TXT"
     ttl     = 200
     data    = ["v=DKIM1;k=rsa;t=s;p=MIIBIjAN...gkH2v1NTgQdTKfPmDK...YdRiwIDAQAB"]
   }
   

   Where:

   1. yandex_dns_zone parameters:

      • zone: Domain zone. The zone name must end with a dot. You cannot create public top-level domain (TLD) zones. This is a required parameter.
      • folder_id: ID of the folder to create a zone in. If not specified, the default folder is used. This is an optional parameter.
      • name: Zone name. It must be unique within the folder. This is an optional parameter.
      • description: Zone description. This is an optional parameter.
      • labels: Set of DNS zone labels. This is an optional parameter.
      • public: Zone visibility, public or private. This is an optional parameter.
      • private_networks: For a public zone, specify the Virtual Private Cloud resources that this zone is visible to. This is an optional parameter.

   2. yandex_dns_recordset parameters:

      • zone_id: ID of the zone where the record set will be located. This is a required parameter.
      • name: Domain name. This is a required parameter.
      • type: DNS record type. This is a required parameter.
      • ttl: Record time to live (TTL) in seconds before updating the record value. This is an optional parameter.
      • data: Record value. This is an optional parameter.

   For more information about resources you can create with Terraform, see the provider documentation.

2. Apply the changes:

   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.

   Terraform will create all the required resources. You can check the new resources using the management console or this CLI command:

   yc dns zone list-records <zone_name>
   

To create a resource record in a DNS zone, use the updateRecordSets REST API method for the DnsZone resource or the DnsZoneService/UpdateRecordSets gRPC API call.
