Updating a resource record

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To update a DNS zone:

1. See the description of the CLI command for updating a resource record:

   yc dns zone replace-records --help
   

2. Change the record value:

   yc dns zone replace-records --name <zone_name> \
   --record "<domain_name> 600 <record_type> <new_value>"
   

If you do not have Terraform yet, install it and configure its Yandex Cloud provider.

To update a DNS record created with Terraform:

1. Open the Terraform configuration file and edit the fragment describing your DNS record.

   Terraform DNS record description example

   ...
   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"]
   }
   ...
   

2. Check the configuration using this command:

3. Apply the changes:

   1. In the terminal, go to the directory where you edited the configuration file.

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

      terraform validate
      

      If the configuration is correct, you will get this message:

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a detailed list of resources. No changes will be made at this step. Terraform will show any errors found in your configuration.

   4. Apply the changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

   You can verify DNS record changes in the management console or using this CLI command:

   yc dns zone list-records <zone_name>
   

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