Versehentliches Löschen einer VM verhindern

In diesem Dokument wird beschrieben, wie Sie bestimmte VM-Instanzen vor dem Löschen schützen. Legen Sie dazu das Attribut deletionProtection für eine Instanzressource fest. Weitere Informationen zu VM-Instanzen finden Sie in der Dokumentation zu Instanzen.

Ihre Arbeitslast kann bestimmte VM-Instanzen enthalten, die für die Ausführung Ihrer Anwendung oder Dienste wichtig sind, z. B. eine Instanz, auf der ein SQL-Server ausgeführt wird, ein Server, der als Lizenzmanager verwendet wird, und so weiter. Diese VM-Instanzen müssen möglicherweise unbegrenzt laufen. Sie müssen also in der Lage sein, zu verhindern, dass diese VMs gelöscht werden.

Mit dem Flag deletionProtection kann eine VM-Instanz vor versehentlichem Löschen geschützt werden. Wenn ein Nutzer versucht, eine VM-Instanz zu löschen, für die Sie das Flag deletionProtection gesetzt haben, schlägt die Anforderung fehl. Nur ein Nutzer, dem eine Rolle mit der Berechtigung compute.instances.create erteilt wurde, kann das Flag zurücksetzen, damit die Ressource gelöscht werden kann.

Hinweise

Spezifikationen

  • Durch den Löschschutz werden die folgenden Aktionen nicht verhindert:

  • Der Löschschutz kann sowohl auf normale VMs als auch auf präemptive VMs angewendet werden.

  • Der Löschschutz kann nicht auf VMs angewendet werden, die Teil einer verwalteten Instanzgruppe sind, kann aber auf Instanzen angewendet werden, die Teil von nicht verwalteten Instanzgruppen sind.

  • Der Löschschutz kann nicht in Instanzvorlagen festgelegt werden.

Berechtigungen

Zum Ausführen dieser Aufgabe benötigen Sie die folgenden Berechtigungen ODER eine der folgenden IAM-Rollen für die Ressource.

Berechtigungen

  • compute.instances.create

Rollen

  • compute.admin
  • compute.instanceAdmin.v1

Löschschutz während der Instanzerstellung festlegen

Standardmäßig ist der Löschschutz für Ihre Instanz deaktiviert. Aktivieren Sie den Löschschutz mithilfe der folgenden Anweisungen.

Console

  1. Rufen Sie in der Google Cloud Console die Seite Instanz erstellen auf.

    Zur Seite „Instanz erstellen“

  2. Maximieren Sie den Abschnitt Erweiterte Optionen und tun Sie Folgendes:

    1. Maximieren Sie den Bereich Verwaltung.
    2. Klicken Sie das Kästchen Löschschutz aktivieren an.

  3. Fahren Sie mit dem VM-Erstellungsprozess fort.

gcloud

Verwenden Sie beim Erstellen einer VM-Instanz entweder das Flag --deletion-protection oder das Flag no-deletion-protection. Der Löschschutz ist standardmäßig deaktiviert. Aktivieren Sie den Löschschutz wie im Folgenden beschrieben:

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

Dabei steht [INSTANCE_NAME] für den Namen der gewünschten Instanz.

So deaktivieren Sie den Löschschutz während der Erstellung:

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

REST

Fügen Sie in der API beim Erstellen einer VM-Instanz das Attribut deletionProtection in den Anfragetext ein. Beispiel:

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

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

Um den Löschschutz zu deaktivieren, setzen Sie deletionProtection auf false.

Ermitteln, ob für eine Instanz Löschschutz aktiviert ist

Sie können mit dem gcloud tool oder der API feststellen, ob der Löschschutz für eine Instanz aktiviert ist.

Console

  1. Gehen Sie zur Seite der VM-Instanzen.

    Zu „VM-Instanzen“

  2. Wenn Sie dazu aufgefordert werden, wählen Sie Ihr Projekt aus und klicken auf Weiter.

  3. Öffnen Sie auf der Seite VM-Instanzen das Menü Spalten und aktivieren Sie den Löschschutz.

    Option zum Löschen der VM

  4. Eine neue Spalte wird mit dem Löschschutzsymbol angezeigt. Wenn auf einer VM der Löschschutz aktiviert ist, wird das Symbol neben dem Instanznamen angezeigt.

gcloud

Führen Sie in der gcloud CLI den instances describe-Befehl aus und suchen Sie nach dem Feld für den Löschschutz. Beispiel:

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

Das Tool gibt den Wert des Attributs deletionProtection zurück, das entweder auf true oder false festgelegt ist:

deletionProtection: false

REST

Geben Sie in der API eine GET-Anfrage ein und suchen Sie nach dem Feld deletionProtection:

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

Löschschutz für vorhandene Instanzen umschalten

Sie können den Löschschutz für eine vorhandene Instanz unabhängig vom aktuellen Status der Instanz umschalten. Insbesondere müssen Sie die Instanz nicht stoppen, bevor Sie den Löschschutz aktivieren oder deaktivieren können.

Console

  1. Gehen Sie zur Seite der VM-Instanzen.

    Zu „VM-Instanzen“

  2. Wenn Sie dazu aufgefordert werden, wählen Sie Ihr Projekt aus und klicken auf Weiter.

  3. Klicken Sie auf den Namen der Instanz, für die Sie den Löschschutz aktivieren bzw. deaktivieren möchten. Die Seite mit den Instanzdetails wird angezeigt.

  4. Führen Sie auf der Seite mit den Instanzdetails folgende Schritte aus:

    1. Klicken Sie oben auf der Seite auf Bearbeiten.

    2. Klicken Sie unter Löschschutz auf das Kästchen, um den Löschschutz zu aktivieren, oder entfernen Sie das Häkchen, um ihn zu deaktivieren.

      Kästchen zum Löschen der VM

    3. Speichern Sie die Änderungen.

gcloud

Führen Sie mit der gcloud CLI den update-Befehl entweder mit dem Flag --deletion-protection oder --no-deletion-protection aus:

gcloud compute instances update [INSTANCE_NAME] \
    [--deletion-protection | --no-deletion-protection]

Geben Sie z. B. Folgendes ein, um den Löschschutz für eine Instanz namens example-vm zu deaktivieren:

gcloud compute instances update example-vm --deletion-protection
