Running Bottle (back end) + Nodejs (front end) on Google App Engine

I have my Python/bottle backend running on app engine and decided to use Nodejs/ember for the front end. I haven't used Google Cloud a lot but the Managed VMs beta seems to allow me to deploy my project using Docker.

Question: How do I run both back end and front end on the Google cloud and can I actually run it in the same project? I haven't found any documentation how to do the configuration. I'm sure there is a simple answer that I'm not seeing.
