Docker quickstart can not use the web interface

[#1]

Hi Cloudera Community:

I installed the docker Cloudera Quickstart, my system is ubuntu 14.04. I used the following command to start the image:

docker run --hostname=quickstart.cloudera --privileged=true -t -i -p 8888:8888 -p 80:80 cloudera/quickstart /usr/bin/docker-quickstart

It looks like every thing works, but if I tried to open the webbrowser: 

 localhost:8888

Then, it show me the error message: 

This webpage is not available

It is also the same with port 80

Can you tell me, what is the problem?
