Deleting a subnet

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. See the description of the CLI command for deleting a subnet:

   yc vpc subnet delete --help
   

2. Get a list of all subnets in the default folder:

   yc vpc subnet list
   

   Result:

   +----------------------+-----------------------+------------------------+
   |          ID          |         NAME          | ... |       RANGE      |
   +----------------------+-----------------------+------------------------+
   ...
   | e2l0psbfoloe******** | test-subnet-1         | ... | [192.168.0.0/24] |
   ...
   +----------------------+-----------------------+-----+------------------+
   

3. Select the ID or NAME of the subnet you need.

4. Delete the subnet from the default folder:

   yc vpc subnet delete test-subnet-1
   

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

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.

To delete a subnet created using Terraform:

1. Open the Terraform configuration file and delete the fragment with the subnet description.

   Example subnet description in the Terraform configuration

   ...
   resource "yandex_vpc_subnet" "lab-subnet-a" {
     name           = "subnet-1"
     description    = "My first subnet"
     v4_cidr_blocks = ["10.2.0.0/16"]
     zone           = "ru-central1-a"
     network_id     = "${yandex_vpc_network.lab-net.id}"
   }
   ...
   

2. In the command line, go to the directory with the Terraform configuration file.

3. Check the configuration using this command:

   terraform validate
   

   If the configuration is correct, you will get this message:

   Success! The configuration is valid.
   

4. 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.

5. Apply the configuration changes:

   terraform apply
   

6. Confirm the changes: type yes into the terminal and press Enter.

   You can check the update using the management console or this CLI command:

   yc vpc subnet list
   

To delete a subnet, use the delete REST API method for the Subnet resource or the SubnetService/Delete gRPC API call and provide the ID of the subnet to be deleted in the subnetId request parameter.

To get the subnet ID, use the list REST API method for the Subnet resource or the SubnetService/List gRPC API call and provide the folder ID in the folderId request parameter.

To learn how to find out the folder ID, see Getting the folder ID.
