Excluir uma imagem personalizada

Só é possível excluir imagens personalizadas que foram adicionadas por você ou alguém que tenha acesso ao projeto.

Antes de começar

  • Leia o documento Imagens.
  • Configure a autenticação, caso ainda não tenha feito isso. A autenticação é o processo de verificação da sua identidade para acesso a serviços e APIs do Google Cloud. Para executar códigos ou amostras de um ambiente de desenvolvimento local, autentique-se no Compute Engine selecionando uma das seguintes opções:

    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. Install the Google Cloud CLI, then initialize it by running the following command: 

      gcloud init
    2. Set a default region and zone.

      3. Python

      Para usar os exemplos Python desta página em um ambiente de desenvolvimento local, instale e inicialize o gcloud CLI e e configure o Application Default Credentials com suas credenciais de usuário.

      1. Install the Google Cloud CLI.

      2. To initialize the gcloud CLI, run the following command: 

        gcloud init

      3. 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.

      Confira mais informações em Set up authentication for a local development environment.

      REST

      Para usar as amostras da API REST nesta página em um ambiente de desenvolvimento local, use as credenciais fornecidas para gcloud CLI.

        Install the Google Cloud CLI, then initialize it by running the following command: 

        gcloud init

      Para mais informações, consulte Autenticar para usar REST na documentação de autenticação do Google Cloud.

Excluir uma imagem personalizada

Use um dos métodos a seguir para excluir a imagem.

Console

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

    Acessar "Imagens"

  2. Marque a caixa à esquerda da imagem que você quer excluir.

  3. Clique em Excluir na parte superior da página. A imagem será excluída.

gcloud

Use o comando gcloud compute images delete para excluir uma imagem.

gcloud compute images delete IMAGE_NAME

Substitua IMAGE_NAME pelo nome da imagem a ser excluída.

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.
    If there were any warnings during the execution of the operation
    they will be printed to sys.stderr.

    Args:
        operation: a long-running operation you want to wait on.
        verbose_name: (optional) a more verbose name of the operation,
