# Updating a trigger label in Cloud Functions

{% list tabs group=instructions %}

- CLI {#cli}

    If you do not have the Yandex Cloud CLI yet, [install and initialize it](../../../cli/quickstart.md#install).

    The folder used by default is the one specified when [creating](../../../cli/operations/profile/profile-create.md) 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 trigger label, run this command:

    {% note warning %}
    
    The existing labels (`labels`) will be completely overwritten by the ones you provide in your request.
    
    {% endnote %}

    ```bash
    yc serverless trigger update <trigger_name> --labels <key>=<value>
    ```

    Result:

   ```text
   id: a1s9q2li6t**********
   folder_id: b1g9hv2loa**********

- Terraform {#tf}

  For more information about Terraform, [see this tutorial](../../../tutorials/infrastructure-management/terraform-quickstart.md#install-terraform).

  With [Terraform](https://www.terraform.io/), 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](https://github.com/hashicorp/terraform/blob/main/LICENSE). The [Yandex Cloud provider for Terraform](https://github.com/yandex-cloud/terraform-provider-yandex) is distributed under the [MPL-2.0](https://www.mozilla.org/en-US/MPL/2.0/) license.
  
  For more information about the provider resources, see the guides on the [Terraform](https://www.terraform.io/docs/providers/yandex/index.html) website or [its mirror](../../../terraform/index.md).

  To update a trigger label:

  1. Open the Terraform configuration file and edit the `labels` section in the trigger description:

     ```hcl
     ...
     resource "yandex_function_trigger" "my_trigger" {
       name   = "some_name"
	     labels = {
         tf-label    = "tf-label-value"
         empty-label = ""
       }
       description = "any description"
       timer {
         cron_expression = "* * * * ? *"
       }
       function {
         id = "tf-test"
       }
     }
     ...
     ```

     For more on the properties of the `yandex_function_trigger` resource, see [this provider guide](../../../terraform/resources/function_trigger.md).

  1. Validate your configuration using this command:

     ```
     terraform validate
     ```
     
     If the configuration is valid, you will get this message:
     
     ```
     Success! The configuration is valid.
     ```

  1. 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.

  1. Apply the configuration changes:

     ```
     terraform apply
     ```
     
  1. Type `yes` and press **Enter** to confirm the changes.

     You can check the trigger update using this [CLI](../../../cli/quickstart.md) command:

     ```
     yc serverless trigger get <trigger_ID>
     ```

- API {#api}

  To update a trigger label, use the [update](../../triggers/api-ref/Trigger/update.md) REST API method for the [Trigger](../../triggers/api-ref/Trigger/index.md) resource or the [TriggerService/Update](../../triggers/api-ref/grpc/Trigger/update.md) gRPC API call.
