# Beispiel für eine blau/grüne Einsatzvorlage
Die folgende Beispielvorlage richtet eine CodeDeploy blaue/grüne Bereitstellung auf ECS ein, mit einem Fortschritt bei der Weiterleitung des Datenverkehrs von 15 Prozent pro Schritt und einem Stabilisierungszeitraum von 5 Minuten zwischen den einzelnen Schritten.
Durch das Erstellen eines Stacks mit der Vorlage wird die anfängliche Konfiguration der Bereitstellung bereitgestellt. Wenn Sie dann Änderungen an den Eigenschaften der `BlueTaskSet` Ressource vorgenommen haben, die einen Austausch dieser Ressource erfordern, CloudFormation wird im Rahmen des Stack-Updates eine umweltfreundliche Bereitstellung initiiert.
