Updating 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.

To update a DNS zone:

1. View a description of the CLI update record command:

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

To update a DNS record created using Terraform:

1. Open the Terraform configuration file and edit the fragment with the DNS record description.

   Example DNS record description in the Terraform configuration

   ...
   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, 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.

   You can check the DNS record update in the management console or using the CLI command below:

   yc dns zone list-records <zone_name>
   

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