# format 3.x, validated on W10 - there is no "mode/uid/gid" for docker-compose 1.29/W10
# you should provide your private/public RSA key in ./ssh dir (named id_rsa.mpi/id_rsa.mpi.pub)
# docker swarm init, then you have to do // note version_mpinet is the name of the overlay
# docker network create --driver=overlay --attachable yml_mpinet
