# Adding a VM to a placement group

Add an existing [VM](../../concepts/vm.md) to a [placement group](../../concepts/placement-groups.md).

You can manage placement groups with [partition placement](../../concepts/placement-groups.md#partition) using the [CLI](../../../cli/quickstart.md) and [API](../../api-ref/index.md).

{% list tabs group=instructions %}

- Management console {#console}

  1. In the [management console](https://console.yandex.cloud), select the [folder](../../../resource-manager/concepts/resources-hierarchy.md#folder) the placement group belongs to.
  1. Navigate to **Compute Cloud**.
  1. In the left-hand panel, select ![image](../../../_assets/compute/group-placement-pic.svg) **Placement groups**.
  1. Navigate to the **Virtual machine placement groups** tab.
  1. Select the placement group to add a VM to.
  1. Go to the **Virtual machines** panel.
  1. In the top-right corner, click ![image](../../../_assets/plus-sign.svg) **Add VM**.
  1. In the window that opens, select the VM and click **Add**.

  {% note info %}

  You can only add a [VM with the `stopped` status](../../concepts/vm-statuses.md) to a placement group.

  {% endnote %}

- CLI {#cli}

  If you do not have the Yandex Cloud CLI yet, [install and initialize it](../../../cli/quickstart.md#install).

  The folder used by default is the one specified when [creating](../../../cli/operations/profile/profile-create.md) 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. Create a VM:

     ```bash
     yc compute instance create \
       --zone ru-central1-a \
       --name instance-in-group-2
     ```

     Where:
     * `--zone`: [Availability zone](../../../overview/concepts/geo-scope.md) for the VM.
     * `--name`: VM name.

     Result:

     ```text
     id: epdlv1pp5401********
     ...
     ```

  1. View a list of VMs in the placement group:

     ```bash
     yc compute placement-group list-instances \
       --name my-group
     ```

     Where `--name` is the placement group name.

     Result:

     ```text
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     |          ID          |        NAME         |      ZONE ID      | STATUS  | EXTERNAL IP | INTERNAL IP |
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     | epdep2kq6dt5******** | instance-in-group-1 |   ru-central1-a   | RUNNING |             | 10.129.0.5  |
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     ```

  1. Stop the VM by specifying its name in the command below:

     ```bash
     yc compute instance stop instance-in-group-2
     ```

     Result:

     ```text
     id: epdlv1pp5401********
     ...
     status: STOPPED
     ```

  1. Add the VM to the placement group:

     ```bash
     yc compute instance update \
       --name instance-in-group-2 \
       --placement-group-name my-group \
       --placement-group-partition <partition_number>
     ```

     Where:
     * `--name`: VM name.
     * `--placement-group-name`: Placement group name.
     * `--placement-group-partition`: Partition number in the placement group with the [partition placement](../../concepts/placement-groups.md#partition) strategy.

       {% note info %}

       If you do not specify the partition number when adding a VM to a partition placement group, the VM will be added to a random partition.

       {% endnote %}

     Result:

     ```text
     id: epdlv1pp5401********
     ...
     placement_policy:
       placement_group_id: fd83bv4rnsna********
     ```

  1. Check that the VM is now in the placement group:

     ```bash
     yc compute placement-group list-instances \
       --name my-group
     ```

     Where `--name` is the placement group name.

     Result:

     ```text
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     |          ID          |        NAME         |      ZONE ID      | STATUS  | EXTERNAL IP | INTERNAL IP |
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     | epdep2kq6dt5******** | instance-in-group-1 |   ru-central1-a   | RUNNING |             | 10.129.0.5  |
     | epdlv1pp5401******** | instance-in-group-2 |   ru-central1-a   | STOPPED |             | 10.129.0.30 |
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     ```

  1. Start the VM by specifying its name in the command below:

     ```bash
     yc compute instance start instance-in-group-2
     ```

     Result:

     ```text
     id: epdlv1pp5401********
     ...
     status: RUNNING
     ```

- Terraform {#tf}

  With [Terraform](https://www.terraform.io/), 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](https://github.com/hashicorp/terraform/blob/main/LICENSE). The [Yandex Cloud provider for Terraform](https://github.com/yandex-cloud/terraform-provider-yandex) is distributed under the [MPL-2.0](https://www.mozilla.org/en-US/MPL/2.0/) license.
  
  For more information about the provider resources, see the relevant documentation on the [Terraform](https://www.terraform.io/docs/providers/yandex/index.html) website or [its mirror](../../../terraform/index.md).

  If you do not have Terraform yet, [install it and configure the Yandex Cloud provider](../../../tutorials/infrastructure-management/terraform-quickstart.md#install-terraform).
  
  
  To manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), [authenticate](../../../terraform/authentication.md) using the appropriate method.

  To add an existing VM to a placement group:
  1. To the configuration file of the existing VM, add the `placement_group_id` field indicating the `yandex_compute_placement_group` placement group resource.

     Here is an example of the configuration file structure:

     ```hcl
     ...
     resource "yandex_compute_instance" "vm-1" {
       name        = "my-vm"
       platform_id = "standard-v3"
       placement_policy {
         placement_group_id = "${yandex_compute_placement_group.group1.id}"
       }
     }

     resource "yandex_compute_placement_group" "group1" {
       name = "test-pg"
     }
     ...
     ```

     Where `placement_group_id` is the placement group ID.

     {% note info %}

     If you do not specify the partition number when adding a VM to a [partition placement](../../concepts/placement-groups.md#partition) group, the VM will be added to a random partition.

     {% endnote %}

     For more information about the resources you can create with Terraform, see [this provider guide](../../../terraform/resources/compute_instance.md).
  1. In the command line, go to the directory with the Terraform configuration file.
  1. Check the configuration using this command:

     ```bash
     terraform validate
     ```

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

     ```text
     Success! The configuration is valid.
     ```

  1. Run this command:

     ```bash
     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.
  1. Apply the configuration changes:

     ```bash
     terraform apply
     ```

  1. Confirm the changes: type `yes` into the terminal and press **Enter**.

     This will create all the resources you need in the specified folder. You can check that the VM has been added to the placement group using the [management console](https://console.yandex.cloud).

- API {#api}

  Use the [update](../../api-ref/Instance/update.md) REST API method for the [Instance](../../api-ref/Instance/index.md) resource or the [InstanceService/Update](../../api-ref/grpc/Instance/update.md) gRPC API call.
