app.yaml / env

What is app.yaml

You configure your App Engine app's settings in the app.yaml file. The app.yaml file also contains information about your app's code, Node.js runtime, and environment variables. Each service in your app has its own app.yaml file, which acts as a descriptor for its deployment. You must first create the app.yaml file for the default service before you can create and deploy app.yaml files for additional services within your app.
