Fig (http://www.fig.sh/) is an Docker-based development environment tool which is owned by Docker. Originally, we can only deploy to one host at one time. My hack in Docker Global Hack Day #2 is to enable Fig to deploy multiple hosts at one time. In this talk, I'll give a brief introduction to Fig first. Then describe my hack in the hack day. Finally I'll give a short demo about deploying apps to multi hosts at one time.
