now try run image:

$ docker run -p 49160:8080 -d i841712/centos-node-hello 995bfeef4edd723027480fdb43f097e2ba6a97b8fb1d2e9ec679dc1247f68a84

but if check processes, instance not running.

$ docker ps container id        image               command             created             status             ports

any ideas? thank you.

try: docker run -p 49160:8080 -i -t /centos-node-hello /bin/bash
