I have already an account on docker hub, I have yesterday pushed an image.

Then, from another machine, I have downloaded this image (search and pull)
and created a docker container from this image.


To success the dumping process i have to use:



./docker-1.9.0-dev run -d --name test11-container MyImg  /bin/sh -c ‘ My
commands'



That’s it ?
