Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

For more information about the provider resources, see the documentation on the Terraform website or the mirror.

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

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

To delete an alias created with Terraform:

Open the Terraform configuration file and delete the value of the alias in the aliases section, where the device description is located. To remove all aliases, delete the entire aliases section.

Example device description in the Terraform configuration:
```
resource "yandex_iot_core_device" "my_device" {
  registry_id = "<registry_ID>"
  name        = "<device_name>"
  description = "test device for terraform provider documentation"

  aliases = {
    "some-alias1/subtopic" = "$devices/{id}/events/somesubtopic",
    "some-alias2/subtopic" = "$devices/{id}/events/aaa/bbb",
  }
...
}
```
For more information about the yandex_iot_core_device parameters in Terraform, see the relevant provider documentation.
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 correct, you will get this message:
```
Success! The configuration is valid.
```
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.
Apply the configuration changes:
```
terraform apply
```
Confirm the changes: type yes into the terminal and click Enter.

You can verify device aliases in the management console or using the following CLI command:
```
yc iot device get <device_name>
```
