gcloud

L'esempio seguente mostra come creare una prenotazione automatica nella zona us-central1-a per tre istanze N2 con 32 vCPU e Intel Cascade Lake come piattaforma CPU minima. L'esempio mostra anche come creare una singola istanza per consumare la prenotazione.

Per creare la prenotazione automatica di esempio e consumarla, segui questi passaggi:

1. Per creare la prenotazione di esempio, utilizza il comando gcloud compute reservations create:

   gcloud compute reservations create reservation-01 \
       --machine-type=n2-standard-32 \
       --min-cpu-platform="Intel Cascade Lake" \
       --vm-count=3 \
       --zone=us-central1-a
   

2. Per creare un'istanza che consumi la prenotazione di esempio, utilizza il comando gcloud compute instances create con il flag --reservation-affinity impostato su any. Poiché any è la configurazione predefinita, puoi anche omettere questo flag.

   gcloud compute instances create instance-01 \
       --machine-type=n2-standard-32 \
       --min-cpu-platform="Intel Cascade Lake" \
       --reservation-affinity=any \
       --zone=us-central1-a
   

Go

Per creare la prenotazione automatica di esempio usando un template di istanza e creare poi un'istanza per consumare la prenotazione con lo stesso template, utilizza il seguente esempio di codice:

import (
	"context"
	"fmt"
	"io"

	compute "cloud.google.com/go/compute/apiv1"
	computepb "cloud.google.com/go/compute/apiv1/computepb"
	"google.golang.org/protobuf/proto"
)

// consumeAnyReservation creates instance, consuming any available reservation
func consumeAnyReservation(w io.Writer, projectID, zone, instanceName, sourceTemplate string) error {
	// projectID := "your_project_id"
	// zone := "us-west3-a"
	// instanceName := "your_instance_name"
	// sourceTemplate: existing template path. Following formats are allowed:
	//  	- projects/{project_id}/global/instanceTemplates/{template_name}
	//  	- projects/{project_id}/regions/{region}/instanceTemplates/{template_name}
	//  	- https://www.googleapis.com/compute/v1/projects/{project_id}/global/instanceTemplates/instanceTemplate
	//  	- https://www.googleapis.com/compute/v1/projects/{project_id}/regions/{region}/instanceTemplates/instanceTemplate

	ctx := context.Background()

	instancesClient, err := compute.NewInstancesRESTClient(ctx)
	if err != nil {
		return fmt.Errorf("NewInstancesRESTClient: %w", err)
	}
	defer instancesClient.Close()

	req := &computepb.InsertInstanceRequest{
		Project:                projectID,
		Zone:                   zone,
		SourceInstanceTemplate: proto.String(sourceTemplate),
		InstanceResource: &computepb.Instance{
			Name: proto.String(instanceName),
			// specifies that any matching reservation should be consumed
			ReservationAffinity: &computepb.ReservationAffinity{
				ConsumeReservationType: proto.String("ANY_RESERVATION"),
			},
		},
	}

	op, err := instancesClient.Insert(ctx, req)
	if err != nil {
		return fmt.Errorf("unable to create instance: %w", err)
	}

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

	return nil
}

       --machine-type=n2-standard-32 \
       --min-cpu-platform="Intel Cascade Lake" \
       --require-specific-reservation \
       --vm-count=3 \
       --zone=us-central1-a
   

2. Per creare un'istanza che consumi la prenotazione di esempio, utilizza il comando gcloud compute instances create con i flag --reservation e --reservation-affinity=specific:

   gcloud compute instances create instance-02 \
       --machine-type=n2-standard-32 \
       --min-cpu-platform="Intel Cascade Lake" \
       --reservation-affinity=specific \
       --reservation=RESERVATION_URL \
       --zone=us-central1-a
   

   Sostituisci RESERVATION_URL con l'URL della prenotazione. Specifica uno dei seguenti valori:

   • Se hai creato la prenotazione nello stesso progetto: reservation-02

   • Se la prenotazione si trova in un progetto diverso: projects/PROJECT_ID/reservations/reservation-02

Go

REST

L'esempio seguente mostra come creare una prenotazione specifica nella zona us-central1-a per tre istanze N2 con 32 vCPU e Intel Cascade Lake come piattaforma CPU minima. L'esempio mostra anche come creare una singola istanza per consumare la prenotazione.

Per creare la prenotazione specifica di esempio e consumarla, segui questi passaggi:

1. Per creare la prenotazione di esempio, invia una richiesta POST al metodo instances.insert. Nel corpo della richiesta, includi il campo specificReservationRequired impostato su true:

   POST https://compute.googleapis.com/compute/v1/projects/example-project/zones/us-central1-a/reservations
   
   {
     "name": "reservation-02",
     "specificReservation": {
       "count": "3",
       "instanceProperties": {
         "machineType": "n2-standard-32",
         "minCpuPlatform": "Intel Cascade Lake",
       }
     },
     "specificReservationRequired": true
   }
   

2. Per creare un'istanza che consumi la prenotazione di esempio, invia una richiesta POST al metodo instances.insert. Includi quanto segue nel campo reservationAffinity del corpo della richiesta:

   • Il campo consumeReservationType impostato su SPECIFIC_RESERVATION.

   • Il campo key impostato su compute.googleapis.com/reservation-name.

   • Il campo values impostato sull'URL della prenotazione.

   La richiesta è simile alla seguente:

   POST https://compute.googleapis.com/compute/v1/projects/example-project/zones/us-central1-a/instances
   
   {
     "name": "instance-02",
     "machineType": "zones/us-central1-a/machineTypes/n2-standard-32",
     "minCpuPlatform": "Intel Cascade Lake",
     "disks": [
       {
         "boot": true,
         "initializeParams": {
           "sourceImage": "projects/debian-cloud/global/images/family/debian-12"
         }
       }
     ],
     "networkInterfaces": [
       {
         "network": "global/networks/default"
       }
     ],
     "reservationAffinity": {
       "consumeReservationType": "SPECIFIC_RESERVATION",
       "key": "compute.googleapis.com/reservation-name",
       "values": [
         "RESERVATION_URL"
       ]
     }
   }
   

   Sostituisci RESERVATION_URL con l'URL della prenotazione. Specifica uno dei seguenti valori:

   • Se hai creato la prenotazione nello stesso progetto: reservation-02

   • Se la prenotazione si trova in un progetto diverso: projects/PROJECT_ID/reservations/reservation-02
