Written by
Updated at October 30, 2024

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

Assigning a role

  1. In the management console, select the folder where the instance group is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Instance groups.
  4. Select the group you need.
  5. Go to the Access bindings tab.
  6. Click Assign bindings.
  7. In the window that opens, select the group, user, or service account to grant access to the instance group.
  8. Click Add role and select the required roles.
  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 group:

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

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

    yc compute instance-group list

    Result:

    +----------------------+-----------------------+------+
|          ID          |         NAME          | SIZE |
+----------------------+-----------------------+------+
| amc65sbgfqeq******** | first-instance-group  |    2 |
+----------------------+-----------------------+------+

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

    yc compute instance-group list-access-bindings <instance_group_name_or_ID>

  4. Assign the role using the command:

    • To a user:

      yc compute instance-group add-access-binding <instance_group_name_or_ID> \
  --user-account-id <user_ID> \
  --role <role>

      Where:

    • To a service account:

      yc compute instance-group add-access-binding <instance_group_name_or_ID> \
  --service-account-id <service_account_ID> \
  --role <role>

      Where:

Use the updateAccessBindings REST API method for the InstanceGroup resource or the InstanceGroupService/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 instance group is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Instance groups.
  4. Select the group you need.
  5. Go to the Access bindings tab.
  6. Click Assign bindings.
  7. In the window that opens, select the group, user, or service account to grant access to the instance group.
  8. Click Add role and select the required roles.
  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 instance-group list-access-bindings <VM_group_name_or_ID>

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

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

  3. Assign roles:

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

    Where:

    • --access-binding: Role to assign:

      • role: ID of the 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 instance-group set-access-bindings test-group \
  --access-binding role=editor,subject=userAccount:gfei8n54hmfh******** \
  --access-binding role=viewer,subject=userAccount:helj89sfj80a******** \
  --access-binding role=editor,subject=serviceAccount:ajel6l0jcb9s********

Use the setAccessBindings REST API method for the InstanceGroup resource or the InstanceGroupService/SetAccessBindings gRPC API call.

Revoking a role

  1. In the management console, select the folder where the instance group is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Instance groups.
  4. Select the group you need.
  5. Go to the Access bindings tab.
  6. In the line with the user you need, click and select Edit roles.
  7. Click next to a role to delete it.
  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 an instance group:

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

  2. View the roles and assignees for the resource:

    yc compute instance-group list-access-bindings <instance_group_name_or_ID>

  3. To revoke access permissions, run this command:

    yc compute instance-group remove-access-binding <instance_group_name_or_ID> \
  --role <role_ID> \
  --subject <subject_type>:<subject_ID>

    Where:

    • --role: ID of the role to revoke.
    • --subject: Subject to revoke the role from.

    For example, to revoke the viewer role for an instance group from a user with the ajel6l0jcb9s******** ID:

    yc compute instance-group remove-access-binding test-group \
  --role viewer \
  --subject userAccount:ajel6l0jcb9s********

To revoke instance roles, use the updateAccessBindings REST API method for the InstanceGroup resource or the InstanceGroupService/UpdateAccessBindings gRPC API call. In the request body, set the action property to REMOVE and specify the user type and ID in the subject property.
