Updating a trigger in Cloud Functions

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 find out the name or ID of a trigger, get the list of triggers in the folder.

1. See the description of the CLI command for updating trigger settings:

   yc serverless trigger update <trigger_type> --help
   

2. Update the trigger settings, e.g., rename the trigger:

   yc serverless trigger update <trigger_type> <trigger_name> \ 
     --new-name <new_trigger_name> 
   

   Result:

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 edit trigger settings:

1. Open the Terraform configuration file and edit the trigger settings:

   ...
   resource "yandex_function_trigger" "my_trigger" {
     name        = "some_name"
     description = "any description"
     timer {
       cron_expression = "* * * * ? *"
     }
     function {
       id = "tf-test"
     }
   }
   ...
   

   For more information about the yandex_function_trigger properties in Terraform, see this provider guide.

2. Create the resources:

   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 check the trigger updates using the management console or this CLI command:

yc serverless trigger get <trigger_ID>

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