Sie können die Zugriffssteuerung für KI-Anwendungen auf Projektebene konfigurieren. Wenn Sie den Zugriff auf KI-Anwendungen über die Console gewähren möchten, weisen Sie einem Hauptkonto für das Projekt, das die AI Applications-Engine enthält, die Rolle „Discovery Engine-Administrator“ zu.
Wenn Sie Zugriff auf KI-Anwendungen gewähren möchten, folgen Sie der Anleitung unter Einzelne Rolle zuweisen in der IAM-Dokumentation. Beachten Sie dabei Folgendes:
Wählen Sie in Schritt 2 ein Projekt aus.
Geben Sie in Schritt 4 beim Auswählen einer Rolle Discovery Engine in den Filter ein und klicken Sie dann auf Discovery Engine-Administrator.
Wenn Sie Inhaber des Projekts sind, haben Sie automatisch die Rolle „Discovery Engine-Administrator“ für dieses Projekt.
Informationen zum Gewähren des Zugriffs auf KI-Anwendungen für andere Nutzer, Gruppen und Dienstkonten finden Sie unter Zugriffssteuerung mit IAM.
