gcloud

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

Para criar a reserva automática de exemplo e consumi-la, faça o seguinte:

1. Para criar a reserva de exemplo, 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 sinalização --reservation-affinity definida como any . Como any é a configuração padrão, você também pode omitir esse sinalizador.

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

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 seguinte exemplo de código:

	compute "cloud.google.com/go/compute/apiv1"
	computepb "cloud.google.com/go/compute/apiv1/computepb"

// consumeAnyReservation creates instance, consuming any available reservation

	//  	- 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)

       }
     }
   }
   

2. Para criar uma instância que consuma a reserva de exemplo, faça uma solicitação POST ao método instances.insert . No corpo da solicitação, inclua o campo consumeReservationType definido como ANY_RESERVATION . Entretanto, como ANY_RESERVATION é a configuração padrão, você também pode omitir o campo.

       --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 sinalizações --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 um projeto diferente: projects/ PROJECT_ID /reservations/reservation-02

DESCANSAR

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 plataforma de CPU mínima. Também mostra como criar uma única instância para consumir a reserva.

Para criar a reserva específica de exemplo e consumi-la, faça o seguinte:

1. Para criar a reserva de exemplo, 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 ao 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 um projeto diferente: projects/ PROJECT_ID /reservations/reservation-02
