To me, the whole point of Appengine is to abstract out system administration. GCE (like AWS) abstracts out the systems, but not the administration - you suddenly become responsible for all the scaling, fault-tolerance, and all the subsystems that Appengine manages for you.
Confusingly enough Google Container Engine != GCE. GCE is Google Comput Engine, which doesn't abstract out much of the administration. Google Container Engine (or GKE) on the other hand does abstract out most of the administration via Kubernetes. We were recently attempting to use appengine for something but gave up due to how bad the support for Go is and migrated to GKE. It definitely isn't quite as abstracted as Appengine but it's darn close.
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.
Microservice based architectures, or SOAs, are ideal for segmenting operational and development tasks. Using Container Engine (which != GCE) will give users a BETTER way to abstract out system administration. You imply contrary.
My request is for a tool which would provide this functionality in the form of code which exposes an App Engine like interface to the developer, except it's running in Container Engine. Given Container Engine has the required code to restart processes that fail and oodles of other automated goodies, this give the fault tolerance desired.

Given the "tool" doesn't appear to exist IRL, that statement is illogical. You can't not use something that doesn't exist. And, if there really did exist a migration tool that provided additional operational abstraction inside the framework you were migrating to, you'd run the risk of being in conflict if you didn't consider using it.
