I believe you're talking about GCE (Compute Engine), while @kordless is talking about Container Engine.

I've tried Containers with Google App Engine Flexible Environment (in beta now) and liked that it's much more customizable than standard GAE. Basically, you just need any Docker container listening on port 8080. But deploy time took 10-20 minutes, so I'm still preferring Standard. Hopefully they'll fix that before GA release.
