Comment 3 Luis Pabón 2016-04-28 04:48:38 UTC 
This looks like incorrect configuration.  Only one RHGS container is supported per node.  Running two container will cause the port conflict which is shown above.  I think this bug is invalid, right?
Comment 4 Neha 2016-04-28 05:01:30 UTC 
It has only one RHGS container running, its conflicting with the port used by Host system.
Comment 5 Humble Chirammal 2016-05-24 09:25:16 UTC 
Updated RHGS 3 layered docker image based on RHGS 3.1.3 and RHEL 7.2.2 available (rhgs-server-docker-3.1.3-8). Brew build @ https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=496477 . This has '3.7.9-6.el7rhgs' gluster package and the fix for this issue.
