How to run same container on all Docker Swarm nodes -

-

i'm getting feet wet docker swarm because we're looking @ ways configure our compute cluster make more containerized. have small farm of 16 computers , i'd able have each node pull down same image, run same container, , accept jobs openmpi program running on master node.

nothing openmpi specific this, containers have able open ssh ports , master must able log them. i've got working single docker container , works.

now i'm learning docker machine , docker swarm way manage 16 nodes. can tell, once set swarm, can set docker_host (or use -h) send "docker run", , swarm manager decide node runs requested container. got working using simple node list instead of messing discovery services, , far good.

but want run same container on nodes in 1 command. possible?

docker 1.12 introduced global services , passing --mode global run command docker schedule service nodes.

using docker swarm can use labels , negative affinity filters gain same result:

openmpi:   environment:     - "affinity:container!=*openmpi*"   labels:     - "com.myself.name=openmpi"
