Environment Variable `GAE_APPENGINE_HOSTNAME` not working

[travisoneill]

Points to an empty string not your-app-id.appspot.com as stated in the docs: https://cloud.google.com/appengine/docs/flexible/python/runtime#environment_variables

@travisoneill Thanks for the report. Where do you see the docs for google-cloud-python referring to that environment variable?

$ cd ~/path/to/google-cloud-python
$ git grep GAE_
$ git grep appspot

Is this from the docs for the gcloud command-line tool? If so, this library is not that thing.

@tseaver It's from the App Engine docs linked above my previous comment for the Python flexible environment runtime:

https://cloud.google.com/appengine/docs/flexible/python/runtime#environment_variables
The following environment variables are set by the runtime environment:

PORT is set to the port that will receive HTTP requests.
GAE_LONG_APP_ID is set to the Project ID associated with your application, which is visible in the Google Cloud Platform Console.
GAE_MODULE_NAME is set to the module name specified in your application's app.yaml, or default.
GAE_APPENGINE_HOSTNAME is set to the hostname for your application, typically your-app-id.appspot.com.

When I print os.environ the key is there 'GAE_APPENGINE_HOSTNAME': '' but just an empty string value. If this is, in fact, intended behavior, I think the docs should be clarified on that point, as they seem to suggest it is available by default.

The other environment variables listed appear to be working.

@travisoneill This project is not App Engine related (though most / all of our code can be used in an App Engine project). This is a library for interacting with Google Cloud APIs in Python.

The App Engine issue tracker is here: https://code.google.com/p/googleappengine/issues/list

Sorry we couldn't be more help.

To be slightly more helpful, we are changing some of the environment variables in GAE flexible, so we'll update the documentation shortly. :)
