API

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

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To add a label to a trigger, run the command:

yc serverless trigger add-labels <trigger_name> --labels <key>=<value>

Result:

id: a1s9q2li6t**********
folder_id: b1g9hv2loa**********
created_at: "2023-08-01T12:36:14.321Z"
name: my-trigger
description: Trigger for uploaded objects
labels:

rule:

    event_type:
      - OBJECT_STORAGE_EVENT_TYPE_CREATE_OBJECT
    bucket_id: **********
    batch_settings:
      size: "10"
      cutoff: 10s
    invoke_function:
      function_id: d4e5muirrt**********
      function_tag: $latest
      service_account_id: ajek0fou8e**********

For more information about Terraform, see the documentation.

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 relevant documentation on the Terraform website or its mirror.

To add a trigger label:

Open the Terraform configuration file and add the labels section to the trigger description:

...
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 information about the yandex_function_trigger resource parameters in Terraform, see the provider documentation.

Check the configuration 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 check the trigger update using this CLI command:
```
yc serverless trigger get <trigger_ID>
```

To add a trigger label, use the update REST API method for the Trigger resource or the TriggerService/Update gRPC API call.
