Un'app App Engine viene configurata utilizzando un file app.yaml, che contiene risorse di CPU, memoria, rete e disco, scalabilità e altre impostazioni generali, incluse le variabili di ambiente.
Informazioni sui app.yaml file
Puoi specificare la configurazione del runtime per la tua app Python,
incluse versioni e URL, nel file app.yaml. Questo file funge da descrittore di deployment di una versione specifica del servizio.
Prima di poter creare e implementare file app.yaml per servizi aggiuntivi, devi creare il file app.yaml per il servizio default della tua app.
Il seguente app.yaml mostra come configurare l'app per utilizzare
l'ultima versione di Python. Per utilizzare qualsiasi altra versione supportata di Python,
devi aggiornare il file app.yaml. Per ulteriori informazioni, vedi
Runtime Python.

A seconda della complessità del servizio della tua app, potrebbe essere necessario definire
solo alcuni elementi nel file app.yaml corrispondente. L'esempio seguente
mostra i requisiti di una semplice app Python
nell'ambiente flessibile:
Puoi specificare un nome univoco per i file app.yaml, ma devi anche
specificare il nome del file con il comando
deployment. Ad esempio, se assegni al file app.yaml il nome service-name-app.yaml
o app.flexible.yaml, devi eseguire il deployment dell'app utilizzando:

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)."]]
