Will the new version of docker swarm in docker 1.12 support the
-P, --publish-all option? If not how would I have my docker service containers get a random port when it needs one? As of right now all docker services I run will simply attach themselves to the port I assign with -p, for example
-p 80:80 .
For reference here is the --help entry for -P, --publish-all in the last version of docker:
-P, --publish-all Publish all exposed ports to random ports
