Borrar una imagen personalizada

Solo puedes borrar imágenes personalizadas que tú o alguien que tenga acceso al proyecto hayan agregado.

Si quieres conservar una copia de seguridad de la imagen, exporta la imagen personalizada a Cloud Storage antes de borrarla.

Antes de comenzar

  • Lee el documento Imágenes.
  • Si aún no lo hiciste, configura la autenticación. La autenticación verifica tu identidad para acceder a los Google Cloud servicios y las APIs. Para ejecutar código o muestras desde un entorno de desarrollo local, puedes autenticarte en Compute Engine seleccionando una de las siguientes opciones:

    Select the tab for how you plan to use the samples on this page:

    Console

    When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

    gcloud

    1. Instala Google Cloud CLI. Después de la instalación, inicializa Google Cloud CLI ejecutando el siguiente comando: 

      gcloud init

      Si usas un proveedor de identidad externo (IdP), primero debes acceder a gcloud CLI con tu identidad federada.

    2. Set a default region and zone.

    Python

    Para usar las muestras de Python de esta página en un entorno de desarrollo local, instala e inicializa gcloud CLI y, luego, configura las credenciales predeterminadas de la aplicación con tus credenciales de usuario.

      Instala Google Cloud CLI.

      Si usas un proveedor de identidad externo (IdP), primero debes acceder a gcloud CLI con tu identidad federada.

      If you're using a local shell, then create local authentication credentials for your user account: 

      gcloud auth application-default login

      You don't need to do this if you're using Cloud Shell.

      If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

    Para obtener más información, consulta Set up authentication for a local development environment.

    REST

    Para usar las muestras de la API de REST en esta página en un entorno de desarrollo local, debes usar las credenciales que proporciones a gcloud CLI.

      Instala Google Cloud CLI.

      Si usas un proveedor de identidad externo (IdP), primero debes acceder a gcloud CLI con tu identidad federada.

    Para obtener más información, consulta Autentícate para usar REST en la documentación de autenticación de Google Cloud .

Borrar una imagen personalizada

Usa uno de los siguientes métodos para borrar la imagen.

Console

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

    Ir a Imágenes

  2. Marca la casilla a la izquierda de la imagen que deseas borrar.

  3. Haz clic en Borrar en la parte superior de la página. La imagen se borrará.

gcloud

Usa el comando gcloud compute images delete para borrar una imagen.

gcloud compute images delete IMAGE_NAME

Reemplaza IMAGE_NAME por el nombre de la imagen que deseas borrar.

Go

import (
	"context"
	"fmt"
	"io"

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

// Deletes the specified disk image
func deleteDiskImage(
	w io.Writer,
	projectID, imageName string,
) error {
	// projectID := "your_project_id"
	// imageName := "your_image"

	ctx := context.Background()
	imagesClient, err := compute.NewImagesRESTClient(ctx)
	if err != nil {
		return fmt.Errorf("NewImagesRESTClient: %w", err)
	}
	defer imagesClient.Close()

	req := computepb.DeleteImageRequest{
		Image:   imageName,
		Project: projectID,
	}

	op, err := imagesClient.Delete(ctx, &req)

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

	fmt.Fprintf(w, "Disk image %s deleted\n", imageName)

	return nil
}

    Waits for the extended (long-running) operation to complete.

    If the operation is successful, it will return its result.
    If the operation ends with an error, an exception will be raised.
