Unable to start a ubuntu container in openshift-origin

Question

Am trying to bring up a ubuntu container in a POD in openshift. I have setup my local docker registry and have configured DNS accordingly. Starting the ubuntu container with just docker works fine without any issues. When I deploy the POD, I can see that my docker ubuntu image is pulled successfully, but doesnt succeed in starting the same. It fails with back-off pulling image error. Is this because my entry point does not have any background process running in side the container ?

"openshift.io/container.ubuntu.image.entrypoint": "[\"top\"]",
