Creating a placement group

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

The folder specified when creating the CLI profile is used by default. 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 the --folder-name or --folder-id parameter.

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

   yc compute placement-group create --help
   

2. Create a placement group in the default folder with one of the following placement strategies:

   • Spread placement:

     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:

     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.

3. Check that the placement group has been added:

   yc compute placement-group list
   

   Result:

   +----------------------+----------+----------+
   |          ID          |   NAME   | STRATEGY |
   +----------------------+----------+----------+
   | fd83bv4rnsna******** | my-group | SPREAD   |
   +----------------------+----------+----------+
   

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 documentation on the Terraform website or mirror website.

If you do not have Terraform yet, install it and configure its Yandex Cloud provider.

1. In the configuration file, define the placement group parameters:

   • name: Placement group name. The name format is as follows:

     • It must be from 2 to 63 characters long.
     • It may contain lowercase Latin letters, numbers, and hyphens.
     • It must start with a letter and cannot end with a hyphen.

   • folder_id: ID of the folder to create a placement group in.

   • description: Placement group description.

   Here is an example of the configuration file structure:

   resource "yandex_compute_placement_group" "group1" {
     name        = "<placement_group_name>"
     folder_id   = "<folder_ID>"
     description = "<placement_group_description>"
   }
   

   For more information about the yandex_compute_placement_group resource parameters in Terraform, see the relevant provider documentation.

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 their 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.

   All the resources you need will then be created in the specified folder. You can check the new resources and their settings using the management console or this CLI command:

   yc compute placement-group list
   

Use the create REST API method for the PlacementGroup resource or the PlacementGroupService/Create gRPC API call.
