Updating a resource record

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

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

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>" \
   --description "<description>"
   

Where:

• --name: Zone name. It must be unique within a folder.
• --record: DNS record containing the domain name, TTL, record type, and record value.
• --description: Description for the new records. If this parameter is not set, the description will be an empty string. This is an optional setting.

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

To manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), authenticate using the appropriate method.

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"]
     description = "Web server A record"
   }
   ...
   

2. Check the configuration using this command:

   terraform validate
   

3. Apply the changes:

   1. In the terminal, navigate to the configuration file directory.

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

      terraform validate
      

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

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a list of resources and their properties. No changes will be made at this step. Terraform will show any errors in the configuration.

   4. Apply the configuration 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.
