Now i have to replace the default image (taged latest) with the new one, and fix the docker-compose.yml. Do you agree so i can do so ?

Weird, travis is giving an error on the line that I have requested a change. It should be working though.

@rafaelcn Alright ! i'll update the default image and modify the docker-compose.yml
