Deleting function scaling settings

To delete any scaling setting other than the number of calls processed concurrently by a single function instance (concurrency), run this command:

yc serverless function remove-scaling-policy \
  --id=<function_ID> \
  --tag=\$latest

Where:

• --id: Function ID. To find out the ID, request a list of functions.
• --tag: Function version tag.

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.

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

To delete any scaling setting other than the number of calls processed concurrently by a single function instance (concurrency):

1. In the configuration file, describe the parameters of resources you want to create:

   • yandex_function_scaling_policy: Description of function scaling settings.
     • function_id: Function ID.
     • policy: Scaling settings:
       • policy.0.tag: Function version tag.
       • policy.0.zone_instances_limit: Number of function instances. Set the 0 value.
       • policy.0.zone_requests_limit: Number of calls in progress. Set the 0 value.

   Here is an example of the configuration file structure:

   resource "yandex_function_scaling_policy" "my_scaling_policy" {
       function_id = "are1samplefu********"
       policy {
           tag                  = "$latest"
           zone_instances_limit = 0
           zone_requests_limit  = 0
       }
   }
   

   For more information about yandex_function_scaling_policy properties, see this Terraform article.

2. Check the configuration using this command:

   terraform validate
   

   If the configuration is correct, you will get this message:

   Success! The configuration is valid.
   

3. Run this command:

   terraform plan
   

   You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

4. Apply the changes:

   terraform apply
   

5. Type yes and press Enter to confirm the changes.

You can check the deletion of the scaling settings using the management console or this CLI command:

yc serverless function list-scaling-policies <function_name_or_ID>

To delete any function scaling setting other than the number of calls processed concurrently by a single function instance (concurrency), use the removeScalingPolicy REST API method for the Function resource or the FunctionService/RemoveScalingPolicy gRPC API call.
