This exposes the /export directory, making it possible to mount it from other
containers. It also makes it possible to bind a local folder to the internal /export
mount point using the native Docker for Mac/Windows and Kinematic.
This takes the image size from 823.1MB (current edge) to 281.8MB.
The following steps are taken:
0) Use go-alpine for a much smaller base image
1) Perform all actions in 1 step to eliminate diff images
2) Remove unused files created after setup
Currently, the Dockerfile is broken because it installs Go 1.5
while the minimum required version is 1.5.1.
Also, switch to a minimval version of Ubuntu (ubuntu-debootstrap)
and reduce the image size by 70M in unneeded dependencies.
