删除预留

---

本文档介绍如何删除预留。

如果您不再需要预留，请将其删除以免预留的资源继续产生费用。如果您不再需要共享预留，只能使用所有者项目将其删除。

准备工作

• 如果您尚未设置身份验证，请进行设置。身份验证是通过其进行身份验证以访问 Google Cloud 服务和 API 的过程。如需从本地开发环境运行代码或示例，您可以选择以下任一选项向 Compute Engine 进行身份验证：
  

  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

     Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
  2. Set a default region and zone.

  Go

  如需在本地开发环境中使用本页面上的 Go 示例，请安装并初始化 gcloud CLI，然后使用您的用户凭据设置应用默认凭据。

  1. Install the Google Cloud CLI.

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

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  如需了解详情，请参阅 Set up authentication for a local development environment。

  Java

  如需在本地开发环境中使用本页面上的 Java 示例，请安装并初始化 gcloud CLI，然后使用您的用户凭据设置应用默认凭据。

  1. Install the Google Cloud CLI.

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

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  如需了解详情，请参阅 Set up authentication for a local development environment。

  Node.js

  如需在本地开发环境中使用本页面上的 Node.js 示例，请安装并初始化 gcloud CLI，然后使用您的用户凭据设置应用默认凭据。

  1. Install the Google Cloud CLI.

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

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  如需了解详情，请参阅 Set up authentication for a local development environment。

  Python

  如需在本地开发环境中使用本页面上的 Python 示例，请安装并初始化 gcloud CLI，然后使用您的用户凭据设置应用默认凭据。

  1. Install the Google Cloud CLI.

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

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  如需了解详情，请参阅 Set up authentication for a local development environment。

  REST

  如需在本地开发环境中使用本页面上的 REST API 示例，请使用您提供给 gcloud CLI 的凭据。

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

  gcloud init

  如需了解详情，请参阅 Google Cloud 身份验证文档中的使用 REST 时进行身份验证。

删除预留

在删除预留之前，请确保满足以下条件：

• 预留未与承诺相关联。

• 如果您要删除特定预留，请执行以下一项或多项操作，确保没有任何使用该预留的虚拟机 (VM) 实例：

  • 删除虚拟机。

  • 更新虚拟机的 reservationAffinity 属性。

删除预留后，您便无需再为预留付费，并且预留的虚拟机将不再为您预留。之前预留的虚拟机将继续运行，并且这些虚拟机会不断产生费用。

如需同时删除多个预订，请使用 Google Cloud 控制台。否则，如需删除单个预订，请选择以下任一选项：

控制台

1. 在 Google Cloud 控制台中，转到预留页面。

   转到“预留”

2. 在按需预订标签页（默认）上，选择您要删除的预订。

3. 点击 删除。

4. 请点击删除来确认操作。

   同时删除一个或多个预订最长可能需要一分钟才能完成。

gcloud

如需删除预留，请使用 gcloud compute reservations delete 命令。

gcloud compute reservations delete RESERVATION_NAME \
    --zone=ZONE

替换以下内容：

• RESERVATION_NAME：要删除的现有预留的名称。

• ZONE：预留所在的可用区。

Go

import (
	"context"
	"fmt"
	"io"

	compute "cloud.google.com/go/compute/apiv1"
	computepb "cloud.google.com/go/compute/apiv1/computepb"
)

// Deletes the reservation for given project and zone
func deleteReservation(w io.Writer, projectID, zone, reservationName string) error {
	// projectID := "your_project_id"
	// zone := "us-west3-a"
	// reservationName := "your_reservation_name"

	ctx := context.Background()
	reservationsClient, err := compute.NewReservationsRESTClient(ctx)
	if err != nil {
		return err
	}
	defer reservationsClient.Close()

	req := &computepb.DeleteReservationRequest{
		Project:     projectID,
		Reservation: reservationName,
		Zone:        zone,
	}

	op, err := reservationsClient.Delete(ctx, req)
	if err != nil {
		return fmt.Errorf("unable to delete reservation: %w", err)
	}

	if err = op.Wait(ctx); err != nil {
		return fmt.Errorf("unable to wait for the operation: %w", err)
	}

	fmt.Fprintf(w, "Reservation deleted\n")

	return nil
}

REST

如需删除预留，请向 reservation.delete 方法发出 DELETE 请求。

DELETE https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/reservations/RESERVATION_NAME

替换以下内容：

• PROJECT_ID：您用于创建预留的项目的 ID。

• ZONE：预留所在的可用区。

• RESERVATION_NAME：要删除的预留的名称。
