Enabling a software-accelerated network

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.

1. See the description of the CLI command for updating VM parameters:

   yc compute instance update --help
   

2. Get a list of VMs in the default folder:

   yc compute instance list
   

   Result:

   +----------------------+-----------------+---------------+---------+----------------------+
   |          ID          |       NAME      |    ZONE ID    | STATUS  |     DESCRIPTION      |
   +----------------------+-----------------+---------------+---------+----------------------+
   | fhm0b28lgfp4******** | first-instance  | ru-central1-a | RUNNING | my first vm via CLI  |
   | fhm9gk85nj7g******** | second-instance | ru-central1-a | RUNNING | my second vm via CLI |
   +----------------------+-----------------+---------------+---------+----------------------+
   

3. Select the ID or NAME of the relevant VM and stop it. For example, to stop a VM named first-instance, run this command:

   yc compute instance stop first-instance
   

4. Enable a software-accelerated network:

   1. Run this command:

      yc compute instance update first-instance \
        --network-settings type=software-accelerated
      

      Where --network-settings is the parameter that switches the network type.

      Result:

      id: fhm0b28lgfp4********
      folder_id: b1gbnv36zqf5********
      created_at: "2023-05-24T09:28:11Z"
      name: first-instance
      zone_id: ru-central1-a
      platform_id: standard-v3
      resources:
        memory: "2147483648"
        cores: "2"
        core_fraction: "100"
      status: STOPPED
      ...
      network_settings:
        type: SOFTWARE_ACCELERATED
      placement_policy: {}
      

   2. Run the VM:

      yc compute instance start first-instance
      

To disable a software-accelerated network, stop the VM and run this command:

yc compute instance update first-instance \
  --network-settings type=standard

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 enable a software accelerated network for a VM:

1. In the configuration file, add the network_acceleration_type parameter to the yandex_compute_instance resource description:

   resource "yandex_compute_instance" "example" {
     ...
     network_acceleration_type = "software_accelerated"
     ...
   }
   

   Where network_acceleration_type is the network acceleration type. The possible values are:

   • software_accelerated: Software-accelerated network.
   • standard: Standard network. Specify this value to disable software accelerated network.

   For more information about yandex_compute_instance properties, see this provider guide.

2. Create the resources:

   1. In the terminal, navigate to the configuration file directory.

   2. Make sure the configuration is correct using this command:

      terraform validate
      

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

      Success! The configuration is valid.
      

   3. 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.

   4. Apply the configuration changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

Use the update REST API method for the Instance resource or the InstanceService/Update gRPC API call.

To enable software accelerated network, in the request body, set networkSettings.type to SOFTWARE_ACCELERATED; to disable, set to STANDARD.
