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 update an alias created with Terraform:
-
Open the Terraform configuration file and edit the alias value in the
aliases
section, in the device description fragment.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
resource 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:

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.
