You can only set environment variables in app engine through the app.yaml and they can be accessed by your application instance.

You can define environment variables in app.yaml to make them available to the app:

env_variables:
MY_VAR: 'my value'

access with os.environ

import os
os.environ.get('MY_VAR', 'default value')

The app.yaml file must be valid YAML and must follow the app.yaml syntax.

The example given isn't YAML. It's a jinja template file used to create a configuration file.

There might be simpler ways but here's a long shot: you can generate a valid app.yaml with the right environment variables (with their values) from a script.

  • template.jinja - template to generate app.yaml
  • generate_app_yaml.py - python script to generate app.yaml
