Deleting a subnet

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

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

1. View 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 do not have Terraform yet, install it and configure the Yandex Cloud provider.

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.

To delete a subnet created using Terraform:

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

   Example of a 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, navigate 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
   

   You will see a detailed list of resources. No changes will be made at this step. If the configuration contains errors, Terraform will show them.

5. Apply the changes:

   terraform apply
   

6. Type yes and press Enter to confirm changes.

   You can check the update using the management console or these CLI commands:

   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 delete 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.
