Der Support für Cloud Deployment Manager endet am 31. Dezember 2025. Wenn Sie derzeit Deployment Manager verwenden, müssen Sie bis zum 31. Dezember 2025 zu Infrastructure Manager oder einer alternativen Bereitstellungstechnologie migrieren, damit Ihre Dienste ohne Unterbrechung weiterlaufen.
Mit Sammlungen den Überblick behalten
Sie können Inhalte basierend auf Ihren Einstellungen speichern und kategorisieren.
Nachdem Sie eine Bereitstellung eingerichtet haben, können Sie sie aktualisieren, wenn sich Ihre Anwendung weiterentwickelt. In Deployment Manager haben Sie zwei Möglichkeiten, ein Deployment zu aktualisieren:
Ressourcen in die Bereitstellung einfügen oder aus ihr entfernen
Einige Attribute vorhandener Ressourcen in Ihrer Bereitstellung aktualisieren
Deployment Manager verwendet die zugrunde liegenden APIs von Google Cloud -Diensten, um Ressourcen in Ihrem Deployment zu verwalten. Deployment Manager kann vorhandene Ressourcen aktualisieren, wenn die entsprechende API die Methode update oder patch enthält.
Ursprüngliche Konfiguration bereitstellen
Stellen Sie in diesem Schritt die Konfiguration bereit, die Sie später aktualisieren. Rufen Sie dazu den Ordner im GitHub-Repository auf und stellen Sie die Konfiguration bereit:
Bei der Konfiguration werden zwei virtuelle Maschinen (VMs) bereitgestellt, die ein Startskript ausführen.
Dies ist die VM-Vorlage:

In der aktualisierten Vorlage wurde im Abschnitt metadata das Startskript der VM geändert:

Sie verwenden diese aktualisierte Vorlage, um die von Ihnen erstellte Bereitstellung zu ändern.
Vorschau des Updates anzeigen
Führen Sie den Befehl update mit dem Flag --preview aus, um eine Vorschau der aktualisierten Bereitstellung anzeigen zu lassen:
Prüfen Sie, ob die Aktualisierung vorgenommen wurde. Starten Sie dazu zuerst die Instanzen neu, um das neue Startskript zu verwenden. Starten Sie the-first-vm neu:
gcloud compute instances reset the-first-vm
Der Neustart der Instanz kann einige Zeit in Anspruch nehmen. Warten Sie ein paar Minuten, bis Sie die Änderung bestätigen.
Neues Startskript bestätigen
Rufen Sie die externe IP-Adresse von the-first-vm ab:
Öffnen Sie einen Browser und kopieren Sie die IP-Adresse in die Adressleiste, um Ihre Instanz aufzurufen.
Auf der Seite sollte jetzt eine Begrüßungsnachricht mit dem Text "Deployment Manager bids you good day!" (Deployment Manager heißt Sie herzlich willkommen!) angezeigt werden.
Sie können diese Schritte auch mit the-second-vm wiederholen. Dabei wird eine etwas andere Nachricht angezeigt.
Bereitstellung löschen
Wie bei den vorherigen Schritten empfehlen wir Ihnen auch hier, die Bereitstellung zu löschen, um Kosten zu vermeiden. Führen Sie den folgenden Befehl aus, um die Bereitstellung zu löschen:
