Warning

Yandex IoT Core is no longer available to new users.

Current users can create resources until November 1, 2026. Afterwards, the service will go read-only and cease to operate on December 1, 2026. For more information on the timing and procedure, see Service shutdown.

Note

The broker is at the Preview stage.

To start exchanging messages between broker clients, you must log in. This section describes how to manage broker certificates for the relevant authorization method.

Note

When using an X.509 certificate along with a password, the password has higher priority.

To access a broker, use its unique ID or name. For info on how to get the unique broker ID or name, see Getting information about a broker.

Getting a list of broker certificates

Management console

CLI

API

In the management console, select the folder where the broker is located.
Go to IoT Core.
In the left-hand panel, select Brokers.
Select the broker. A list of certificates will be displayed in the Certificates section.

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

Get a list of broker certificates:

yc iot broker certificate list --broker-name my-broker

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 manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), authenticate using the appropriate method.

To add a certificate to a broker created using Terraform:

In the configuration file, specify the properties of the resources you want to create:
- yandex_iot_core_broker: Broker parameters:
  - name: Broker name.
  - description: Broker description.
  - certificates: List of broker certificates for authentication with certificates.
Example broker description in the Terraform configuration:
```
resource "yandex_iot_core_broker" "my_broker" {
  name        = "test-broker"
  description = "test broker for terraform provider documentation"
...
  certificates = [
    file("<path_to_first_certificate_file>"),
    file("<path_to_second_certificate_file>")
  ]
...
}
```
For more information about yandex_iot_core_broker properties, see this Terraform provider guide.
In the command line, change to the folder where you edited the configuration file.
Make sure the configuration file is correct using this command:
```
terraform validate
```
If the configuration is valid, you will get this message:
```
Success! The configuration is valid.
```
Run this command:
```
terraform plan
```
You will see a list of resources and their properties. No changes will be made at this step. Terraform will show any errors in the configuration.
Apply the configuration changes:
```
terraform apply
```
Confirm the changes: type yes into the terminal and press Enter.

You can verify broker certificates using the management console or this CLI command:
```
yc iot broker certificate list --broker-name <broker_name>
```

To add a certificate to a broker, use the addCertificate REST API method for the Broker resource or the BrokerService/AddCertificate gRPC API call.
