apollo: Dreamview does not appear on localhost after build succeeds.

After the build has passed successfully on Ubuntu 17.10:

abhisheknaik96@in_dev_docker:/apollo$ sudo bash scripts/bootstrap.sh
Started supervisord with dev conf
Start roscore...
voice_detector: started
Dreamview is running at http://localhost:8888

But Firefox cannot connect to localhost:8888. apollo/data/log/ has the following:
