API

In the management console, navigate to the folder where you want to add a label to a connector.
Select Serverless Integrations.
In the left-hand panel, click EventRouter.
Select the bus you need.
Navigate to the Connectors tab.
In the line with the connector you need, click and select Edit.
In the Labels field, click Add label.
Enter the key and the value, and press Enter.
Click Save.

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 add a label to a connector, run this command:

Warning

The existing labels (labels) will be completely overwritten by the ones you provide in your request.

yc serverless eventrouter connector update <connector_name_or_ID> \
  --labels <label_list>

Where --labels is a list of labels. You can specify one label or multiple labels separated by commas in <key1>=<value1>,<key2>=<value2> format.

Result:

bus_id: f66qn4p7uk6p********

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 add a label to a connector:

Open the Terraform configuration file. Under labels, enlist the labels in key = "value" format.

Example of a connector description in the Terraform configuration file:

resource "yandex_serverless_eventrouter_connector" "example_connector" {
  bus_id              = "<bus_ID>"
  name                = "<connector_name>"
  description         = "<connector_description>"
  deletion_protection = <true|false>

  labels = {
    <key_1> = "<value_1>"
    <key_2> = "<value_2>"
    ...
    <key_n> = "<value_n>"
  }
  ...
}

For more information about the yandex_serverless_eventrouter_connector resource parameters, see this Terraform article.

Apply the changes:
1. In the terminal, go to the directory where you edited the configuration file.
2. Make sure the configuration file is correct 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.
Terraform will create all the required resources. You can check the updates using the management console or this CLI command:
```
yc serverless eventrouter connector list
```

To add a label to a connector, use the Update REST API method for the Connector resource or the Connector/Update gRPC API call.
