Docker Build

Collecting some thoughts:

Consider using Jib to build Docker images for deployment to GKE/GCE/Flex or even other environments.

Is it plausible to take an Eclipse project and/or an Eclipse App Engine project and package it as a Docker image?

What would need to be true about the project for this to work? E.g. what facets and files does it need to have?

What additional information do we need to collect from the user in order to do this that is not already in their project? E.g. container registry address, base image, etc. How much of this can we infer from the project?

While `gcloud app deploy` builds from a Dockerfile by default, it can deploy an image from a local registry instead.

Perhaps set up a meeting to sketch this out and discuss.
