Currently the docker image size is 160MB because it includes temporary files created during the compilation step.

This change is using a separate build stage to compile the static binary which is then copied to the target image. The resulting image size is 20MB

Some additional changes:

lock down the base images using sha256 checksums
change the user to nobody because we don't need to be root to execute the program

Fixes #23

Is it possible to do a re-release of 1.4.0 or a point release of 1.4.1 so the changes are available?

Could a new release please be cut with this change?
