Written by
Updated at November 26, 2024

To grant a user, group, or service account access to a VM placement group, assign a role for it.

Assigning a role

  1. In the management console, select the folder where the placement group is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Placement groups.
  4. On the Virtual machine placement groups tab, click the name of the group.
  5. Go to the Access bindings tab.
  6. Click Assign bindings.
  7. In the window that opens, select a group, user, or service account to be granted access to the placement group.
  8. Click Add role and select the required role.
  9. Click Save.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

  1. See the CLI command description for assigning a role for an instance placement group:

    yc compute placement-group add-access-binding --help

  2. Get a list of instance placement groups in the default folder:

    yc compute placement-group list

  3. View the list of roles already assigned for the resource:

    yc compute placement-group list-access-bindings <placement_group_ID>

  4. Assign the role using the command:

    • To a user:

      yc compute placement-group add-access-binding <placement_group_ID> \
  --user-account-id <user_ID> \
  --role <role>

      Where:

      • --user-account-id: User ID. To assign a role to all authenticated users, use the --all-authenticated-users flag.
      • --role: Role to assign.

    • To a service account:

      yc compute placement-group add-access-binding <placement_group_ID> \
  --service-account-id <service_account_ID> \
  --role <role>

      Where:

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 don't have Terraform, install it and configure the Yandex Cloud provider.

To assign a role to access a VM placement group using Terraform:

  1. In the Terraform configuration file, describe the parameters of the resources you want to create:

    resource "yandex_compute_placement_group_iam_binding" "sa-access" {
  placement_group_id = "<placement_group_ID>"
  role               = "<role>"
  members            = ["<subject_type>:<subject_ID>"]
}

    Where:

    • placement_group_id: VM placement group ID.
    • role: Role to assign.
    • members: List of types and IDs of subjects the roles are assigned to. Specify it as userAccount:<user_ID> or serviceAccount:<service_account_ID>.

    For more information about the yandex_compute_placement_group_iam_binding resource parameters, see the provider documentation.

  2. Apply the changes:

    1. In the terminal, change to the folder where you edited the configuration file.

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

      terraform validate

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.

    3. Run the command:

      terraform plan

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

    4. Apply the configuration changes:

      terraform apply

    5. Confirm the changes: type yes in the terminal and press Enter.

    Terraform will create all the required resources. You can check the update using the management console or this CLI command:

    yc compute placement-group list-access-bindings <placement_group_ID>

To assign a role, use the updateAccessBindings REST API method for the PlacementGroup resource or the PlacementGroupService/UpdateAccessBindings gRPC API call. In the request body, set the action property to ADD and specify the user type and ID in the subject property.

Assigning multiple roles

  1. In the management console, select the folder where the placement group is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Placement groups.
  4. On the Virtual machine placement groups tab, click the name of the group.
  5. Go to the Access bindings tab.
  6. Click Assign bindings.
  7. In the window that opens, select a group, user, or service account to be granted access to the placement group.
  8. Click Add role and select the required role.
  9. To add another role, click Add role.
  10. Click Save.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

You can assign multiple roles using the set-access-bindings command.

Alert

The set-access-bindings command completely rewrites the access permissions for the resource. All current resource roles will be deleted.

  1. Make sure the resource has no roles assigned that you would not want to lose:

    yc compute placement-group list-access-bindings <placement_group_ID>

  2. See the CLI command description for assigning roles for an instance placement group:

    yc compute placement-group set-access-bindings --help

  3. Assign roles:

    yc compute placement-group set-access-bindings <placement_group_ID> \
  --access-binding role=<role>,subject=<subject_type>:<subject_ID> \
  --access-binding role=<role>,subject=<subject_type>:<subject_ID>

    Where:

    • --access-binding: Parameters for setting access permissions:

      • role: Role to assign.
      • subject: Type and ID of the subject getting the role.

    For example, assign roles to multiple users and a service account:

    yc compute placement-group set-access-bindings my-group \
  --access-binding role=editor,subject=userAccount:gfei8n54hmfh********
  --access-binding role=viewer,subject=userAccount:helj89sfj80a********
  --access-binding role=editor,subject=serviceAccount:ajel6l0jcb9s********

The setAccessBindings method and the PlacementGroupService/SetAccessBindings call completely overwrite access permissions for the resource. All current resource roles will be deleted.

Revoking a role

  1. In the management console, select the folder where the placement group is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Placement groups.
  4. On the Virtual machine placement groups tab, click the name of the group.
  5. Go to the Access bindings tab.
  6. In the line with the user you need, click and select Edit roles.
  7. Next to the role, click .
  8. Click Save.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

  1. See the CLI command description for revoking a role for a placement group:

    yc compute placement-group remove-access-binding --help

  2. View the roles and assignees for the resource:

    yc compute placement-group list-access-bindings <placement_group_ID>

  3. To revoke access permissions, run this command:

    yc compute placement-group remove-access-binding <placement_group_ID> \
  --role=<role> \
  --subject=<subject_type>:<subject_ID> \

    Where:

    • --role: ID of the role to revoke.
    • --subject: Type and ID of the subject getting the role.

    For example, this command revokes the viewer role for a placement group from a user with the ajel6l0jcb9s******** ID:

    yc compute placement-group remove-access-binding my-group \
  --role viewer \
  --subject userAccount:ajel6l0jcb9s********
