Aliases are linked to specific devices. To update an alias, you need the device ID or name.

Management console

CLI

Terraform

API

To update an alias:

In the management console, select a folder in which to update an alias.
Select IoT Core.
Select the required registry from the list.
On the left side of the window, select the Devices section.
Click to the right of the appropriate device name and select Edit from the drop-down list.
Update the values of the alias fields.
Click Save.

If you do not have the Yandex Cloud (CLI) command line interface yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

Update device aliases:

Warning

The existing topic_aliases will be completely overwritten by the ones you provide in your request.

yc iot device update first --topic-aliases 'events=$devices/areqjd6un3af********/events,commands=$devices/areqjd6un3af********/commands'

Result:

id: areqjd6un3af********
registry_id: arenou2oj4ct********
created_at: "2019-09-16T10:41:06.489Z"
name: first
topic_aliases:
  commands: $devices/areqjd6un3af********/commands
  events: $devices/areqjd6un3af********/events

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the documentation on the Terraform website or mirror website.

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

To update an alias created with Terraform:

Open the Terraform configuration file and edit the alias value in the aliases section, in the device description fragment.

Example device description in the Terraform configuration:

resource "yandex_iot_core_device" "my_device" {
  registry_id = "<registry_ID>"
  name        = "<device_name>"
  description = "test device for terraform provider documentation"

  aliases = {
    "some-alias1/subtopic" = "$devices/{id}/events/somesubtopic",
    "some-alias2/subtopic" = "$devices/{id}/events/aaa/bbb",
  }
...
}

For more information about the yandex_iot_core_device resource parameters in Terraform, see the relevant provider documentation.

In the command line, change to the folder where you edited the configuration file.
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.
```
Run this command:
```
terraform plan
```
The terminal will display a list of resources with parameters. No changes will be made at this step. If the configuration contains any errors, Terraform will point them out.
Apply the configuration changes:
```
terraform apply
```
Confirm the changes: type yes into the terminal and press Enter.

You can verify device aliases in the management console or using the following CLI command:
```
yc iot device get <device_name>
```

To update an alias, use the update REST API method for the Device resource or the DeviceService/Update gRPC API call.
