AsteriskDockerDemo missing configs.tar.gz

I'm interested in this project, and I'm new to Asterisk. 

You conveniently have a docker file for an Asterisk instance in AsteriskDockerDemo, but the start.sh references  /root/configs.tar.gz. That file isn't in the repository (and it would need to be referenced in a COPY in the docker file). Any chance that could be added?
