Updating a resource record
You can update the value of a resource record. To update a record:
- In the management console
, select a folder to modify the DNS zone record in. - Select Cloud DNS.
- Select the zone from the list.
- Click
next to the record you need and select Edit. - Edit the record TTL, value, or description.
- Click Save.
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:
-
See the description of the CLI command for updating a resource record:
yc dns zone replace-records --help -
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 flag is not set, the description will be empty. This is an optional setting.
If you do not have Terraform yet, install it and configure the Yandex Cloud provider.
To update a DNS record created with Terraform:
-
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" } ... -

To update a DNS resource record, use the updateRecordSets REST API method for the DnsZone resource or the DnsZoneService/UpdateRecordSets gRPC API call.
The value of resource TXT records cannot contain more than 255 characters per line and 1024 characters total. If the new value contains more characters, split it into multiple values.
