s provides a script to start a trytond session using a docker container (jcnorman/tryton). It is linked to postgres and sshd images The script checks to see if a container is running each image, and starts a container for it, if not. It then starts an interactive container After starting and getting the # prompt, type supervisord. This starts postgres, sshd, and trytond.
You can then, in a different terminal, type "tryton" (without the quotes) to start a tryton session.
