Python image from python:3.x-alpine

Will python image from python:3.x-alpine a better choice if upgrading tornado to 6.x?

This is a valid option, indeed. I had chosen an Ubuntu base image from phusion, because I am more familiar to Debian based distributions as a development and production environment. But as far as I can see Docker is also using Alpine to reduce their images sizes.

So we can change that for the Dockerfile.

See commit b45d353

I will merge everything into the development as soon as I finished on working at the version 0.3.0 milestone.

Glad you have finished that work.
And it seems that another problem occured when upgrading to Python3 due to the difference between Py3 and Py2 on absolute vs relative imports.

see cookiecutter-tornado/{{cookiecutter.project_slug}}/{{cookiecutter.project_slug}}/urls.py

from handlers import base

# should fix under Python3
from .handlers import base

My temporary plan looks like this

demo
|__app
    |__url.py
    |__handlers
        |__user.py

# url.py
from app.handlers import user
...

Hope you can find a better way to solve it.
