This file acts as a deployment descriptor of a specific [service](/appengine/docs/standard/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\nGenerally, your `app.yaml` file requires only the `runtime` element for a simple\nGo 1.12+ app in the standard environment, for\nexample:\n\n\n runtime: go125\n\n\nApp Engine provides default values for all other settings, including\nthe [F1 instance class](/appengine/docs/standard#instance_classes), which\ndetermines the memory and CPU resources that are available to your app, and\n[automatic scaling](/appengine/docs/standard/how-instances-are-managed#scaling_types),\nwhich controls how and when new instances of your app are created.\n\nIf you need to override the default settings, create an `app.yaml` file and\nspecify the settings you need. For more information, see\n[`app.yaml` file reference](/appengine/docs/standard/reference/app-yaml).\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/standard/testing-and-deploying-your-app)\nas well. For example, if you name your `app.yaml` file `service-name-app.yaml`\nor `app.standard.yaml`, then you must deploy your app using either: \n\n gcloud app deploy service-name-app.yaml\n gcloud app deploy app.standard.yaml\n\nTo learn more about structuring multiple services and `app.yaml` files in your app, see [Structuring web services](/appengine/docs/standard/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/standard/reference/app-yaml)."]]
