This image is based on fis-gtm:ubuntu14.04. The difference is - there are all development dependencies preinstalled, which simplify hacking of a sources if you want to.
Beware, that GT.M is not compilable under Ubuntu without some massaging - the recommended source tree is git://anonscm.debian.org/debian-med/fis-gtm.git which does have all Ubuntu specific patches available under
Assuming you do have GT.M sources available in the current directory you could start development environment via these commands:
> docker run -ti -v "$PWD:/tmp/fis-gtm" tsafin/fis-gtm-devel:ubuntu14.04
> docker run -ti -v "%CD%:/tmp/fis-gtm" tsafin/fis-gtm-devel:ubuntu14.04
