无法在Google云平台中添加app.yaml

Question

Recently I follow this guide : https://cloud.google.com/appengine/docs/standard/php/cloud-sql/using-cloud-sql-mysql

However, I am stuck at step7

Add the Cloud SQL instance connection name, database, user, and password to the environment variables in app.yaml.

Where I app.yaml is located?

Answer 1

The guide you're following is to setup and use Cloud SQL in a GAE app.

The app.yaml is the mandatory (part of) that GAE app's configuration and should be located in the directory from which later in the guide you will run your development server and deploy your application.

In the guide's code on github the file is app.yaml
