service 'web' failed error when running Dockerfile

[nuljon]

Hi, I tried to install the Docker container per the Readme instructions.

It fails with the following error:

Although I did not edit anything first, I am on a windows machine. So, I added dos2unix against the manage.py file in the Docker file, which was my guess for the source of the 'python\r' issue. However, despite successfully installing and running dos2unix command during the docker sequence, the same error remains. Maybe I didn't do something right? I do not see where else the 'python\r' could be coming from.
