Excluir reservas

Neste documento, explicamos como excluir reservas. Para saber como excluir solicitações de reserva adiantada, consulte Cancelar ou excluir solicitações de reserva adiantada.

Exclua uma reserva para interromper as cobranças pelos recursos reservados que você não precisa mais.

Limitações

Antes de excluir uma reserva, considere o seguinte:

  • Só é possível excluir uma reserva compartilhada no mesmo projeto em que ela foi criada.

  • Só é possível excluir uma reserva especificamente segmentada se nenhuma instância do Compute Engine a consumir. Se alguma instância consumir a reserva, faça uma destas ações antes de excluí-la:

    • Excluir as instâncias

    • Interrompa ou suspenda as instâncias

  • Só é possível excluir uma reserva criada automaticamente para uma reserva adiantada após o término do período de reserva.

  • Só é possível excluir uma reserva anexada a um compromisso se você primeiro desvincular ela substituindo a reserva.

Antes de começar

Funções exigidas

Para receber a permissão necessária para excluir reservas, peça ao administrador para conceder a você o papel do IAM de Administrador do Compute (roles/compute.admin) no projeto. Para mais informações sobre a concessão de papéis, consulte Gerenciar o acesso a projetos, pastas e organizações.

Esse papel predefinido contém a permissão compute.reservations.delete, que é necessária para excluir reservas.

Também é possível receber essa permissão com papéis personalizados ou outros papéis predefinidos.

Excluir uma reserva

Se você excluir uma reserva que possa ser consumida automaticamente por qualquer instância de computação correspondente, todas as instâncias que consomem a reserva excluída continuarão em execução. Você continua sendo cobrado por essas instâncias.

É possível excluir uma ou várias reservas de uma só vez. Para várias reservas, use o console Google Cloud . Para reservas únicas, selecione uma das seguintes opções:

Console

  1. No console do Google Cloud , acesse a página Reservas.

    Acessar "Reservas"

  2. Na guia Reservas sob demanda (padrão), selecione as reservas que você quer excluir.

  3. Clique em Excluir.

  4. Para confirmar, clique em Excluir.

gcloud

Para excluir uma reserva, use o comando gcloud compute reservations delete:

gcloud compute reservations delete RESERVATION_NAME \
    --zone=ZONE

Substitua:

  • RESERVATION_NAME: o nome da reserva.

  • ZONE: a zona em que a reserva existe.

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

Para excluir uma reserva, faça uma solicitação DELETE ao método reservation.delete:

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

Substitua:

  • PROJECT_ID: o ID do projeto em que você criou a reserva.

  • ZONE: a zona em que a reserva existe.

  • RESERVATION_NAME: o nome da reserva.
