Docker Distributed Application Bundle(DAB) no network creation options -

before new version of docker using docker-compose -h :swarm_manager_port distribute services. in new version docker introduced stack & bundle system distribute apps,however couldn't find option set fixed ip , subnet containers via overlay network compose , classic swarm. in compose file,i declare network ipv4 & subnet options set. know how can assign constant ip (e.g.10.1.2.3) containers via bundle , why bundle file not support network options "networks" in compose ? thanks

at moment not appear creation of network part of dab file spec. it's still in development/experimental, might change, the readme on dabs @ time of answer states,

networks service containers should connected to. entity deploying bundle should create networks needed.
