Create a reservation for a single project

This document explains how to create a single-project reservation, which can be consumed only by virtual machine (VM) instances in the same project. To learn more about reservations, see Reservations of Compute Engine zonal resources.

For other methods of creating reservations, see instead the following pages:

  • If you have any 1-year or 3-years commitments in the current project, then your reserved resources automatically receive any applicable committed use discounts. You can also create and attach a reservation to a commitment when you purchase the commitment. To learn more, see Attach reservations to commitments.

  • To create a reservation that can be used by multiple projects, see Create a shared reservation.

Before you begin

  • Review the requirements and restrictions for reservations.
  • Set up authentication.

    Select the tab for how you plan to use the samples on this page:

    Console

    When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

    gcloud

    1. Install the Google Cloud CLI, then initialize it by running the following command: 

      gcloud init
    2. Set a default region and zone.

    Terraform

    To use the Terraform samples on this page from a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

    1. Install the Google Cloud CLI.

    2. To initialize the gcloud CLI, run the following command: 

      gcloud init

    3. Create local authentication credentials for your Google Account:

    For more information, see Set up authentication for a local development environment.

    REST

    To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.

      Install the Google Cloud CLI, then initialize it by running the following command: 

      gcloud init

Required roles

To get the permissions that you need to create single-project reservations, ask your administrator to grant you the Compute Admin (roles/compute.admin) IAM role on the project. For more information about granting roles, see Manage access.

This predefined role contains the permissions required to create single-project reservations. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

The following permissions are required to create single-project reservations:

  • compute.reservations.create on the project
  • To specify an instance template: compute.instanceTemplates.useReadOnly on the instance template

You might also be able to get these permissions with custom roles or other predefined roles.

Create a single-project reservation

This section explains how to create single-project reservations.

To consume a reservation, a VM must have properties that exactly match that reservation. To specify the properties of the VMs that you want to reserve, select one of the following sections in this document:

By default, a reservation can be automatically consumed by any VMs with properties that match it. If you want to control reservation consumption, do one or more of the following:

Additionally, you can specify a compact placement policy when creating a single-project reservation. A compact placement policy specifies that VMs are to be located as close to each other as possible to reduce network latency.

Specify an instance template

To create a single-project reservation by specifying an instance template, use the Google Cloud console, gcloud CLI, or Compute Engine API.

Console

To create a single-project reservation by specifying an instance template, do the following:

  1. In the Google Cloud console, go to the Reservations page.

    Go to Reservations

  2. Click Create reservation.

    The Create a reservation page opens.

  3. In the Name field, enter a name for your reservation.

  4. Select the Region and Zone where you want to reserve resources.

  5. In the Share type section, click Local (default).

  6. In the Use with VM instance section, select one of the following options:

    • To allow matching VMs to automatically consume this reservation, click Use reservation automatically (default).

    • To consume this reservation's resources only when creating matching VMs that specifically target this reservation by name, click Select specific reservation.

  7. In the Number of VM instances field, enter the number of VMs that you want to reserve.

  8. In the Machine configuration section, do the following:

    1. To specify the properties of your VMs from an existing instance template, select Use instance template.

    2. In the Instance template field, select the instance template of your choice. If you select a regional instance template, you can only reserve resources within the region of the instance template.

  9. In the Auto-delete section, you can enable the auto-delete option to let Compute Engine automatically delete the reservation at a specific date and time. Automatically deleting reservations can be useful to avoid unnecessary charges when you stop consuming the reservation.

  10. To create the reservation, click Create.

    The Reservations page opens. Creating the single-project reservation might take up to a minute to complete.

gcloud

To create a single-project reservation by specifying an instance template, use the gcloud compute reservations create command.

      POST https://compute.googleapis.com/compute/beta/projects/example-project/zones/us-central1-a/reservations

{
  "name": "example-reservation",
  "deleteAfterDuration": {
    "seconds": "DELETE_AFTER_DURATION"
  },
  ...
}

      Replace DELETE_AFTER_DURATION with a duration in seconds. For example, specify 86400 for 86,400 seconds (1 day).

Terraform

To create a single-project reservation, use the google_compute_reservation Terraform resource. To specify a reservation for a single project, omit the share_settings block (default) or set the share_type field to LOCAL.

compute/reservation/main.tf 

resource "google_compute_reservation" "gce_reservation_local" {
  name = "gce-reservation-local"
  zone = "us-central1-c"

  share_settings {
    share_type = "LOCAL"
  }

  specific_reservation {
    count = 1
    instance_properties {
      machine_type = "n2-standard-2"
    }
  }
}
