使用App Engine golang灵活环境，在测试时访问app.yaml

Question

I am porting a golang service from App Engine standard environment to the flexible environment, and have a question about accessing app.yaml during development/testing.

In my app.yaml I have a section where I set environment variables, that I later access in the code via os.GetEnv(...):

env_variables:
  FORGE_CLIENT_ID: 'my-client-id'
  FORGE_CLIENT_SECRET: 'my-client-secret'

In the App Engine standard environment, this runs fine, as I am using the app engine development server dev-server.py, which I believe takes care of reading the app.yaml file and making these environment variables available.

However, in the flexible environment during development, the service is started simply with go run *.go, and the app doesn't seem to pick up any information in app.yaml, meaning I get an error that my environment variables are not set.

I understand that app.yaml is used during deployment in the flexible environment, but I don't understand how or if it is used during development. How do I access these environment variables from my development server?

Thanks.

For Google App Engine flexible, the dev server don't use "app.yaml", as the configuration is set locally. A workaround for this would be to set the environment variables before running the dev server. You can check this question for setting those variables just for that command.
