刪除保留項目

本文說明如何刪除預訂。如要瞭解如何刪除未來預留項目要求，請參閱取消或刪除未來預留項目要求。

刪除預留項目，停止為不再需要的預留資源付費。

限制

刪除預訂前，請考量以下事項：

  • 您只能刪除建立共用保留項目的專案中的共用保留項目。

  • 只有在沒有 Compute Engine 執行個體使用時，才能刪除指定目標預留空間。如果有任何執行個體使用預留空間，請在刪除預留空間前，採取下列任一做法：

    • 刪除執行個體

    • 停止或暫停執行個體

  • 您只能在未來預留項目的預留期結束後，刪除自動建立的預留項目。

  • 您必須先取代保留訂單，才能刪除與承諾合約連結的保留訂單。

事前準備

必要的角色

如要取得刪除保留單所需的權限，請要求管理員為您授予專案的 Compute Admin (roles/compute.admin) IAM 角色。如要進一步瞭解如何授予角色，請參閱「管理專案、資料夾和機構的存取權」。

這個預先定義的角色包含 compute.reservations.delete 權限，這是刪除預訂項目所需的權限。

您或許還可透過自訂角色或其他預先定義的角色取得此權限。

刪除預留項目

如果您刪除任何相符運算執行個體可自動使用的保留項目，則任何使用已刪除保留項目的執行個體都會繼續執行。您仍須支付這些執行個體的費用。

您可以刪除單一或多筆預訂。如果要進行多個預訂，請使用 Google Cloud 控制台。針對單一預訂，請選取下列任一選項：

主控台

  1. 在 Google Cloud 控制台，前往「Reservations」(預留項目) 頁面。

    前往「預留項目」

  2. 在「On-demand reservations」分頁 (預設) 中，選取要刪除的預留項目。

  3. 按一下 「刪除」。

  4. 按一下「Delete」(刪除) 確認操作。

gcloud

如要刪除保留項目，請使用 gcloud compute reservations delete 指令：

gcloud compute reservations delete RESERVATION_NAME \
    --zone=ZONE

更改下列內容：

  • RESERVATION_NAME：保留項目的名稱。

  • ZONE：預訂項目所在區域。

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

如要刪除預留項目，請對 reservation.delete 方法發出 DELETE 要求：

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

更改下列內容：

  • PROJECT_ID：您建立預訂項目的專案 ID。

  • ZONE：預訂項目所在區域。

  • RESERVATION_NAME：保留項目的名稱。
