Adding a function label

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 add a label to a function, run the command:

yc serverless function add-labels <function_name> --labels <key>=<value>

Result:

id: b097d9ous3ge********
folder_id: aoek49ghmknn********
created_at: "2019-06-06T11:36:48.688Z"
name: my-beta-function
description: My beta function.
labels:
  test: test
  version: beta
log_group_id: eolv6578frac********
http_invoke_url: https://functions.yandexcloud.net/b097d9ous3ge********

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 documentation on the Terraform website or mirror website.

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

To add a function label:

1. In the Terraform configuration file, add the labels section and specify a list of labels in it in <key>:"<value>" format.

   Example 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"]
       labels = {
         <key_1>:"<value_1>",
         <key_2>:"<value_2>"
       }
       content {
           zip_filename = "<path_to_ZIP_archive>"
       }
   }
   

   For more information about the yandex_function resource properties, see the provider documentation.

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
   

   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.

4. Apply the configuration changes:

   terraform apply
   

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

You can check the addition of function labels using this CLI command:

yc serverless function get <function_name_or_ID>

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