Evitar la eliminación accidental de máquinas virtuales

En este documento se describe cómo proteger instancias de VM específicas frente a la eliminación configurando la propiedad deletionProtection en un recurso Instance. Para obtener más información sobre las instancias de VM, consulta la documentación sobre instancias.

Como parte de tu carga de trabajo, puede que haya determinadas instancias de VM que sean críticas para ejecutar tu aplicación o tus servicios, como una instancia que ejecute un servidor SQL, un servidor que se use como gestor de licencias, etc. Es posible que estas instancias de VM deban seguir ejecutándose indefinidamente, por lo que necesitas una forma de protegerlas para que no se eliminen.

Si se define la marca deletionProtection, una instancia de VM se puede proteger contra la eliminación accidental. Si un usuario intenta eliminar una instancia de VM para la que has definido la marca deletionProtection, la solicitud fallará. Solo un usuario al que se le haya asignado un rol con permiso compute.instances.create puede restablecer la marca para permitir que se elimine el recurso.

Antes de empezar

  • Consulta la documentación sobre instancias.
  • Si aún no lo has hecho, configura la autenticación. La autenticación verifica tu identidad para acceder a Google Cloud servicios y APIs. Para ejecutar código o ejemplos 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 la CLI de Google Cloud ejecutando el siguiente comando: 

      gcloud init

      Si utilizas un proveedor de identidades (IdP) externo, primero debes iniciar sesión en la CLI de gcloud 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.

Configurar la protección contra la eliminación durante la creación de una instancia

De forma predeterminada, la protección contra la eliminación está inhabilitada en tu instancia. Habilita la protección frente a la eliminación siguiendo las instrucciones que se indican a continuación.

Consola

  1. En la Google Cloud consola, ve a la página Crear una instancia.

    Ir a Crear una instancia

  2. Despliega la sección Opciones avanzadas y haz lo siguiente:

    1. Despliega la sección Gestión.
    2. Marca la casilla Habilitar protección frente a la eliminación.

  3. Continúa con el proceso de creación de la VM.

gcloud

Cuando crees una instancia de VM, incluye las marcas --deletion-protection o no-deletion-protection. La protección contra la eliminación está inhabilitada de forma predeterminada. Para habilitarla, sigue estos pasos:

gcloud compute instances create [INSTANCE_NAME] --deletion-protection

En este comando, [INSTANCE_NAME] es el nombre de la instancia que quiere.

Para inhabilitar la protección contra la eliminación durante la creación, sigue estos pasos:

gcloud compute instances create [INSTANCE_NAME] --no-deletion-protection

Go 

import (
	"context"
	"fmt"
	"io"

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

// createInstance sends an instance creation request to the Compute Engine API
// and waits for it to complete.

			},
		},
	}

	op, err := instancesClient.Insert(ctx, req)
	if err != nil {
		return fmt.Errorf("unable to create instance: %w", err)

REST

En la API, al crear una instancia de VM, incluya la propiedad deletionProtection en el cuerpo de la solicitud. Por ejemplo:

POST https://compute.googleapis.com/compute/v1/projects/[PROJECT_ID]/zones/[ZONE]/instances

{
  "name": "[INSTANCE_NAME]",
  "deletionProtection": "true",
  ...
}

Para inhabilitar la protección frente a la eliminación, asigna el valor false a deletionProtection.

Determinar si una instancia tiene habilitada la protección contra la eliminación

Puedes determinar si una instancia tiene habilitada la protección contra la eliminación en la gcloud tool o en la API.

Consola

  1. Ve a la página Instancias de VM.

    Ir a instancias de VM

  2. Si se te solicita, selecciona tu proyecto y haz clic en Continuar.

  3. En la página Instancias de VM, despliega el menú Columnas y habilita Protección contra eliminación.

    Opción de eliminación de la VM.

  4. Aparecerá una nueva columna con el icono de protección contra eliminación. Si una VM tiene habilitada la protección contra eliminación, el icono aparece junto al nombre de la instancia.

gcloud

En la CLI de gcloud, ejecuta el comando instances describe y busca el campo de protección contra eliminación. Por ejemplo:

gcloud compute instances describe example-instance | grep "deletionProtection"

La herramienta devuelve el valor de la propiedad deletionProtection, que puede ser true o false:

deletionProtection: false
