# Creating a VM in a placement group


Create a [VM](../../concepts/vm.md) in 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).

{% note info %}

To create, modify, and edit a [VM](../../concepts/vm.md), you need the `compute.editor` _minimum_ [role](../../security/index.md#compute-editor) for the [folder](../../../resource-manager/concepts/resources-hierarchy.md#folder). To create a VM with a licensed image, you will additionally need the `license-manager.viewer` [role](../../../marketplace/security/index.md#license-manager-viewer).

To create a VM with a [public IP address](../../../vpc/concepts/address.md#public-addresses), you will additionally need the `vpc.publicAdmin` [role](../../../vpc/security/index.md#vpc-public-admin).

- 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. See the description of the [CLI](../../../cli/index.md) command for creating a placement group:

     ```bash
     yc compute placement-group create --help
     ```

  1. Create a placement group in the default [folder](../../../resource-manager/concepts/resources-hierarchy.md#folder) with one of the following placement strategies:

     * [Spread placement](../../concepts/placement-groups.md#spread):
     
       ```bash
       yc compute placement-group create \
         --spread-strategy \
         --name <placement_group_name>
       ```
     
       Where:
     
       * `--spread-strategy`: Shows that spread placement is selected.
       * `--name`: Placement group name.
     
     * [Partition placement](../../concepts/placement-groups.md#partition):
     
       ```bash
       yc compute placement-group create \
         --partitions <number_of_partitions> \
         --name <placement_group_name>
       ```
     
       Where:
     
       * `--partitions`: Shows that partition placement is selected, indicating the number of partitions from `1` to `5`.
       * `--name`: Placement group name.

  1. See the description of the CLI command for creating a VM:

     ```bash
     yc compute instance create --help
     ```

  1. Create a VM:

     ```bash
     yc compute instance create \
       --zone ru-central1-a \
       --name instance-in-group-1 \
       --placement-group-name my-group \
       --placement-group-partition <partition_number>
     ```

     Where:
     * `--zone`: [Availability zone](../../../overview/concepts/geo-scope.md) for the VM.
     * `--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 creating a VM in a partition placement group, the VM will be added to a random partition.

       {% endnote %}

     Result:

     ```text
     id: epdep2kq6dt5********
     ...
     placement_policy:
       placement_group_id: fd83bv4rnsna********
     ```

  1. Check the new VM and its 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  |
     +----------------------+---------------------+-------------------+---------+-------------+-------------+
     ```

- 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 create a VM in a placement group:
  1. In the configuration file, define the VM parameters indicating the `yandex_compute_placement_group` resource in the `placement_group_id` field. The `yandex_compute_instance` resource describes the VM parameters.

     Here is an example of the configuration file structure:

     ```hcl
     ...
     resource "yandex_compute_instance" "vm-1" {
       name        = "linux-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.

     For more information about `yandex_compute_instance` and `yandex_compute_placement_group` properties in 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](../../../resource-manager/concepts/resources-hierarchy.md#folder). You can check that the VM has been created and added to the placement group using the [management console](https://console.yandex.cloud).

- API {#api}

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