Docker

Are you planning on elaborating a little bit more on how you've solved your problems with Docker? I would be very interested in reading about this. More specifically a good approach to solve/improve these two issues:

> If your project uses lots of Gradle/Maven dependencies you might want to cache them in the Docker Image to save few minutes for each build. Then you'll need a strategy on updating Image because of dependencies cache miss.

>In certain cases Docker Container may not stop properly and you may see zombie Containers (very rare, but still possible).
