Running Container but can't view app in browser

Following the getting started docs outlined here I have decided to run the same environment but with the new Docker for Mac app. The docs say that after running the commands I should be able to go to to login but I am not able to pull anything up. I think this is because the app was configured with docker tool box which used a VM ip of the one mentioned above. Doing localhost:80 I get the apps error and favicon, please what am I doing wrong I am new to docker and developing with these new tools.
