To add a label to a bus, run this command:

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

yc serverless eventrouter bus update <bus_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.

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 label to a bus, follow these steps:

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

Example of a bus description in the Terraform configuration file:
```
resource "yandex_serverless_eventrouter_bus" "example_bus" {
  name                = "my-bus"
  description         = "this is my bus"
  deletion_protection = true

  labels = {
    key1 = "value1"
    key2 = "value2"
  }
}
```
For more information about the yandex_serverless_eventrouter_bus resource parameters, see this Terraform article.
Apply the changes:
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.
Terraform will create all the required resources. You can check the updates using the management console or this CLI command:
```
yc serverless eventrouter bus list
```

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