Yeah, you can install it easily via apt-get. I followed the instructions to install the very latest version, as the Ubuntu included version was a bit old: https://docs.docker.com/installation/ubuntulinux/. Fig is another tool, which you should be able to install via the Python package manager pip (http://www.fig.sh/install.html). I think I have a working Fig setup now, but haven't figured out how to reach it from the browser yet.
I did run into a potential problem, which was that I wasn't able to build ChucK on Linux with -g4, only -g, since clang didn't accept the -g4 flag. Is -g4 necessary to produce source maps?
