Deleting a trigger in Serverless Containers

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

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

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

Delete the trigger:

yc serverless trigger delete <trigger_name>

Result:

id: a1s5msktijh2********
folder_id: b1gmit33hgh2********
created_at: "2022-10-24T15:19:15.353909857Z"

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

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

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

To delete a trigger created using Terraform:

1. Open the Terraform configuration file and delete the fragment with the function_trigger resource description:

   Below is an example with the description of the function_trigger resource in the Terraform configuration:

   resource "yandex_function_trigger" "my_trigger" {
     name        = "sc-timer"
     timer {
       cron_expression = "*/5 * ? * * *"
     }
     container {
       id                 = "bbaomb25tl68********"
       service_account_id = "ajej9vu5f62d********"
       retry_attempts     = 1
       retry_interval     = 15
     }
     dlq {
       queue_id           = "yrn:yc:ymq:ru-central1:b1geoelk7fld********:formycontainer"
       service_account_id = "ajej9vu5f62d********"
     }
   }
   

2. Delete resources:

   1. In the terminal, change to the folder where you edited the configuration file.

   2. Make sure the configuration file is correct using the command:

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

   You can check the update using the management console or this CLI command:

   yc serverless trigger list
   

To delete a trigger, use the delete REST API method for the Trigger resource or the TriggerService/Delete gRPC API call.
