Since the Container Service plugin was released alongside XNAT 1.7.3, it has been rapidly improved. The latest version of the Container Service plugin (v1.3.2) enables bulk launching of containers from any project data and sending them to a Docker Swarm setup. Also, a number of minor bugs have been resolved to improve reliability.
