There is an encoding issue with environment variables in Python 3+. Here’s the traceback I get from just importing dockercloud with variables set:

TypeError: a bytes-like object is required, not 'str'
I guess the problem is that in Python 2 str and bytes are the same object type but not in Python 3.
