O exemplo a seguir mostra como criar uma reserva automática na zona us-central1-a para três instâncias N2 com 32 vCPUs e o Intel Cascade Lake como a plataforma de CPU mínima. Ele também mostra como criar uma única instância para consumir a reserva.

Para criar e consumir o exemplo de reserva automática, faça o seguinte:

1. Para criar um exemplo de reserva, siga estas etapas:

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

      Acessar "Reservas"

   2. Na guia Reserva sob demanda (padrão), clique em add_box Criar reserva. A página Criar uma reserva é exibida.

   3. No campo Nome, insira um nome para a reserva. Por exemplo, digite reservation-01.

   4. Selecione a Região e a Zona em que você quer reservar recursos. Por exemplo, selecione us-central1 e us-central1-a, respectivamente.

   5. Na seção Tipo de compartilhamento, faça o seguinte:

      • Para criar uma reserva de projeto único, selecione Local.

gcloud

O exemplo a seguir mostra como criar uma reserva automática na zona us-central1-a para três instâncias N2 com 32 vCPUs e o Intel Cascade Lake como a plataforma de CPU mínima. Ele também mostra como criar uma única instância para consumir a reserva.

Para criar e consumir o exemplo de reserva automática, faça o seguinte:

1. Para criar o exemplo de reserva, use o 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. Para criar uma instância que consuma a reserva de exemplo, use o comando gcloud compute instances create com a flag --reservation-affinity definida como any. Como any é a configuração padrão, você também pode omitir essa 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

Para criar o exemplo de reserva automática usando um modelo de instância e criar uma instância para consumir a reserva usando o mesmo modelo, use o exemplo de código abaixo:

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
}

O exemplo a seguir mostra como criar uma reserva automática na zona us-central1-a para três instâncias N2 com 32 vCPUs e o Intel Cascade Lake como a plataforma de CPU mínima. Ele também mostra como criar uma única instância para consumir a reserva.

Para criar e consumir o exemplo de reserva automática, faça o seguinte:

1. Para criar o exemplo de reserva, faça uma solicitação POST para o método reservations.insert:

       --require-specific-reservation \
       --vm-count=3 \
       --zone=us-central1-a
   

2. Para criar uma instância que consuma a reserva de exemplo, use o comando gcloud compute instances create com as flags --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
   

   Substitua RESERVATION_URL pelo URL da reserva. Especifique um dos seguintes valores:

   • Se você criou a reserva no mesmo projeto: reservation-02

   • Se a reserva estiver em outro projeto: projects/PROJECT_ID/reservations/reservation-02

Go

Os exemplos a seguir mostram como criar uma instância N2 com 32 vCPUs e Intel Cascade Lake como a plataforma de CPU mínima, na zona us-central1-a para consumir uma reserva específica correspondente:

REST

O exemplo a seguir mostra como criar uma reserva específica na zona us-central1-a para três instâncias N2 com 32 vCPUs e Intel Cascade Lake como a plataforma de CPU mínima. Ele também mostra como criar uma única instância para consumir a reserva.

Para criar e consumir a reserva específica de exemplo, faça o seguinte:

1. Para criar o exemplo de reserva, faça uma solicitação POST para o método instances.insert. No corpo da solicitação, inclua o campo specificReservationRequired definido como 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. Para criar uma instância que consuma a reserva de exemplo, faça uma solicitação POST para o método instances.insert. No corpo da solicitação, no campo reservationAffinity, inclua o seguinte:

   • O campo consumeReservationType definido como SPECIFIC_RESERVATION.

   • O campo key definido como compute.googleapis.com/reservation-name.

   • O campo values definido como o URL da reserva.

   A solicitação é semelhante a esta:

   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"
       ]
     }
   }
   

   Substitua RESERVATION_URL pelo URL da reserva. Especifique um dos seguintes valores:

   • Se você criou a reserva no mesmo projeto: reservation-02

   • Se a reserva estiver em outro projeto: projects/PROJECT_ID/reservations/reservation-02
