Eine App Engine-Anwendung wird über eine app.yaml-Datei konfiguriert. Diese enthält Einstellungen für CPU-, Arbeitsspeicher-, Netzwerk- und Datenträgerressourcen, Skalierungen und andere allgemeine Einstellungen, einschließlich Umgebungsvariablen.
app.yaml-Dateien
Sie können die Laufzeitkonfiguration für Ihre Python-Anwendung, einschließlich Versionen und URLs, in der Datei app.yaml angeben. Diese Datei dient als Deployment-Deskriptor für eine bestimmte Dienstversion.
Erstellen Sie zuerst die Datei app.yaml für den Dienst default Ihrer Anwendung. Erst dann können Sie app.yaml-Dateien für zusätzliche Dienste erstellen und bereitstellen.
In der folgenden app.yaml wird veranschaulicht, wie Sie Ihre Anwendung für die Verwendung der aktuellen Version von Python konfigurieren. Wenn Sie eine andere unterstützte Version von Python verwenden möchten, müssen Sie Ihre app.yaml-Datei aktualisieren. Weitere Informationen finden Sie unter Python-Laufzeit.

Je nach Komplexität des Dienstes Ihrer Anwendung müssen Sie möglicherweise nur wenige Elemente in der entsprechenden app.yaml-Datei definieren. In diesem Beispiel wird gezeigt, was eine einfache Python-Anwendung in der flexiblen Umgebung erfordern kann:
Sie können Dateien des Typs app.yaml jeweils eindeutige Namen geben, müssen diese Dateinamen dann aber auch im Bereitstellungsbefehl angeben. Wenn Sie beispielsweise Ihre app.yaml-Datei service-name-app.yaml oder app.flexible.yaml benennen, müssen Sie Ihre Anwendung so bereitstellen:

This file acts as a deployment descriptor of a specific [service](/appengine/docs/flexible/an-overview-of-app-engine) version.\n\n\u003cbr /\u003e\n\n\nYou must first create the `app.yaml` file for the `default` service of your app\nbefore you can create and deploy `app.yaml` files for additional services.\n\n\nThe following `app.yaml` demonstrates how to configure your app to use\nthe latest version of Python. To use any other [supported version](/appengine/docs/flexible/lifecycle/support-schedule#python) of Python,\nyou must update your `app.yaml` file.

The following example\ndemonstrates what a simple Python app might require in the\nflexible environment:\n\n\nYou can specify a unique name for your `app.yaml` files, but then you must\nspecify the file name with the [deployment\ncommand](/appengine/docs/flexible/testing-and-deploying-your-app)\nas well. For example, if you name your `app.yaml` file `service-name-app.yaml`\nor `app.flexible.yaml`, then you must deploy your app using either: \n\n gcloud app deploy service-name-app.yaml\n gcloud app deploy app.flexible.yaml\n\nTo learn more about structuring multiple services and `app.yaml` files in your app, see [Structuring web services](/appengine/docs/flexible/configuration-files).\n\n\u003cbr /\u003e\n\nAll configuration elements\n--------------------------\n\nFor a complete list of all the supported elements in this configuration file,\nsee the\n[`app.yaml` reference](/appengine/docs/flexible/reference/app-yaml)."]]
