Elimina prenotazioni

Questo documento spiega come eliminare le prenotazioni.

Se una prenotazione non serve più, eliminala per interrompere i relativi addebiti per le risorse riservate. Se non hai più bisogno di una prenotazione condivisa, puoi eliminarla solo utilizzando il progetto del proprietario.

Prima di iniziare

Se non l'hai ancora fatto, configura l'autenticazione. L'autenticazione è la procedura mediante la quale la tua identità viene verificata per l'accesso alle API e ai servizi Google Cloud. Per eseguire codice o esempi da un ambiente di sviluppo locale, puoi autenticarti su Compute Engine selezionando una delle seguenti opzioni:

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.

Eliminazione di una prenotazione

Prima di eliminare una prenotazione, assicurati che siano soddisfatte le seguenti condizioni:

La prenotazione non è associata a un impegno.
Se vuoi eliminare una prenotazione specifica, assicurati che nessuna istanza di macchina virtuale (VM) la abbia come destinazione per il consumo svolgendo una o più delle seguenti operazioni:
- Elimina le VM.
- Aggiorna la proprietà reservationAffinity delle VM.

Dopo aver eliminato una prenotazione, non ti verrà più addebitato alcun importo e le VM riservate non saranno più riservate per te. Le VM prenotate in precedenza continuano a essere in esecuzione e continuerai a pagare gli addebiti relativi.

Per eliminare più prenotazioni contemporaneamente, utilizza la console Google Cloud. In caso contrario, per eliminare una singola prenotazione, seleziona una delle seguenti opzioni:

Console

Nella console Google Cloud, vai alla pagina Prenotazioni.

Vai a Prenotazioni
Nella scheda Prenotazioni on demand (predefinita), seleziona le prenotazioni che vuoi eliminare.
Fai clic su Elimina.
Per confermare, fai clic su Elimina.

L'eliminazione di una o più prenotazioni contemporaneamente potrebbe richiedere fino a un minuto.

gcloud

Per eliminare una prenotazione, utilizza il comando gcloud compute reservations delete.

gcloud compute reservations delete RESERVATION_NAME \
    --zone=ZONE

Sostituisci quanto segue:

RESERVATION_NAME: il nome di una prenotazione esistente che vuoi eliminare.
ZONE: la zona in cui si trova la prenotazione.

Vai
