Changing the name of a function

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 change the function name, run the command:

yc serverless function update <function_name> --new-name <new_function_name>

Result:

id: b097d9ous3ge********
folder_id: aoek49ghmknn********
created_at: "2019-06-06T11:36:48.688Z"
name: my-beta-function
labels:

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 change the name of a function:

1. Open the Terraform configuration file and edit the name field in the function description fragment.

   Example of a function description in the Terraform configuration:

   resource "yandex_function" "test-function" {
       name               = "test-function"
       description        = "Test function"
       user_hash          = "first-function"
       runtime            = "python37"
       entrypoint         = "main"
       memory             = "128"
       execution_timeout  = "10"
       service_account_id = "<service_account_ID>"
       tags               = ["my_tag"]
       content {
           zip_filename = "<path_to_ZIP_archive>"
       }
   }
   

   For more information about yandex_function 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 function name update using the management console or this CLI command:

yc serverless function list

To rename a function, use the update REST API method for the Function resource or the FunctionService/Update gRPC API call.
