En el siguiente ejemplo, se muestra cómo crear una reserva automática en la zona us-central1-a para tres instancias de N2 con 32 vCPU y Intel Cascade Lake como la plataforma de CPU mínima. También se muestra cómo crear una sola instancia para consumir la reserva.

Para crear la reserva automática de ejemplo y consumirla, haz lo siguiente:

1. Para crear una reserva de ejemplo, completa los siguientes pasos:

   1. En la consola de Google Cloud, ve a la página Reservas.

      Ir a Reservas

   2. En la pestaña Reserva según demanda (predeterminada), haz clic en add_box Crear reserva. Aparecerá la página Crear una reserva.

   3. En el campo Nombre, ingresa un nombre para la reserva. Por ejemplo, ingresa reservation-01.

gcloud

En el siguiente ejemplo, se muestra cómo crear una reserva automática en la zona us-central1-a para tres instancias de N2 con 32 vCPU y Intel Cascade Lake como la plataforma de CPU mínima. También se muestra cómo crear una sola instancia para consumir la reserva.

Para crear la reserva automática de ejemplo y consumirla, haz lo siguiente:

1. Para crear la reserva de ejemplo, usa el 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 crear una instancia que consuma la reserva de ejemplo, usa el comando gcloud compute instances create con la marca --reservation-affinity establecida en any. Dado que any es la configuración predeterminada, también puedes omitir esta marca.

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

	//  	- 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{

			// specifies that any matching reservation should be consumed
			ReservationAffinity: &computepb.ReservationAffinity{

En el siguiente ejemplo, se muestra cómo crear una reserva automática en la zona us-central1-a para tres instancias de N2 con 32 vCPU y Intel Cascade Lake como la plataforma de CPU mínima. También se muestra cómo crear una sola instancia para consumir la reserva.

Para crear la reserva automática de ejemplo y consumirla, haz lo siguiente:

1. Para crear la reserva de ejemplo, realiza una solicitud POST al método reservations.insert:

   POST https://compute.googleapis.com/compute/v1/projects/example-project/zones/us-central1-a/reservations
   
   {
     "name": "reservation-01",

         "minCpuPlatform": "Intel Cascade Lake",
       }
     }
   }
   

2. Para crear una instancia que consuma la reserva de ejemplo, realiza una solicitud POST al método instances.insert. En el cuerpo de la solicitud, incluye el campo consumeReservationType configurado como ANY_RESERVATION. Sin embargo, como ANY_RESERVATION es la configuración predeterminada, también puedes omitir el campo.

1. Para crear la reserva de ejemplo, usa el comando gcloud compute reservations create con la marca --require-specific-reservation:

   gcloud compute reservations create reservation-02 \
       --machine-type=n2-standard-32 \
       --min-cpu-platform="Intel Cascade Lake" \
       --require-specific-reservation \
       --vm-count=3 \
       --zone=us-central1-a
   

2. Para crear una instancia que consuma la reserva de ejemplo, usa el comando gcloud compute instances create con las marcas --reservation y --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
   

   Reemplaza RESERVATION_URL por la URL de la reserva. Especifica uno de los siguientes valores:

   • Si creaste la reserva en el mismo proyecto, haz lo siguiente: reservation-02

   • Si la reserva está en otro proyecto, haz lo siguiente: projects/PROJECT_ID/reservations/reservation-02

REST

En el siguiente ejemplo, se muestra cómo crear una reserva específica en la zona us-central1-a para tres instancias N2 con 32 vCPU y Intel Cascade Lake como la plataforma de CPU mínima. También se muestra cómo crear una sola instancia para consumir la reserva.

Para crear la reserva específica de ejemplo y consumirla, haz lo siguiente:

1. Para crear la reserva de ejemplo, realiza una solicitud POST al método instances.insert. En el cuerpo de la solicitud, incluye el campo specificReservationRequired configurado 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 crear una instancia que consuma la reserva de ejemplo, realiza una solicitud POST al método instances.insert. En el cuerpo de la solicitud, en el campo reservationAffinity, incluye lo siguiente:

   • El campo consumeReservationType configurado como SPECIFIC_RESERVATION.

   • El campo key configurado como compute.googleapis.com/reservation-name.

   • El campo values configurado en la URL de la reserva.

   La solicitud es similar a la siguiente:

   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"
       ]
     }
   }
   

   Reemplaza RESERVATION_URL por la URL de la reserva. Especifica uno de los siguientes valores:

   • Si creaste la reserva en el mismo proyecto, haz lo siguiente: reservation-02

   • Si la reserva está en otro proyecto, haz lo siguiente: projects/PROJECT_ID/reservations/reservation-02
