El siguiente ejemplo muestra cómo crear una reserva automática en la zona us-central1-a para tres instancias N2 con 32 vCPU e Intel Cascade Lake como plataforma de CPU mínima. También muestra cómo crear una instancia única para consumir la reserva.

Para crear la reserva automática de ejemplo y consumirla, haga 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, use el comando gcloud compute instances create con el indicador --reservation-affinity establecido en any . Dado que any es la configuración predeterminada, también puede omitir este indicador.

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

       --zone=us-central1-a
   

2. Para crear una instancia que consuma la reserva de ejemplo, usa el 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
   

   Reemplace RESERVATION_URL con la URL de la reserva. Especifique uno de los siguientes valores:

   • Si creaste la reserva en el mismo proyecto: reservation-02

   • Si la reserva está en un proyecto diferente: projects/ PROJECT_ID /reservations/reservation-02

DESCANSAR

El siguiente ejemplo muestra cómo crear una reserva específica en la zona us-central1-a para tres instancias N2 con 32 vCPU e Intel Cascade Lake como plataforma de CPU mínima. También muestra cómo crear una instancia única para consumir la reserva.

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

1. Para crear la reserva de ejemplo, realice una solicitud POST al método instances.insert . En el cuerpo de la solicitud, incluya el campo specificReservationRequired establecido en 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, realice una solicitud POST al método instances.insert . En el cuerpo de la solicitud, en el campo reservationAffinity , incluya lo siguiente:

   • El campo consumeReservationType establecido en SPECIFIC_RESERVATION .

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

   • El campo values se establece 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"
       ]
     }
   }
   

   Reemplace RESERVATION_URL con la URL de la reserva. Especifique uno de los siguientes valores:

   • Si creaste la reserva en el mismo proyecto: reservation-02

   • Si la reserva está en un proyecto diferente: projects/ PROJECT_ID /reservations/reservation-02
