title: sudo service mongod start : mongod: unrecognized service
body: <p>I'm testing learning locker which is based on MongoDB it's all inside a ubuntu14.04 docker <a href="https://hub.docker.com/r/hadyrashwan/learninglocker-ubuntu14.04/" rel="nofollow noreferrer">https://hub.docker.com/r/hadyrashwan/learninglocker-ubuntu14.04/</a> . I got it to work but I can't start Mongodb automatically tried the repair command and changing the name in start service command to Mongodb or mongo but not working. but running Mongodb just make it start but I want to start it automatically not opening a terminal and leave it open so the system continues to work</p>
