difference between building a docker from ubuntu base image and python base image?

Question

Docker newbie here.

I was reading the documentation on how to setup Django webapp using Docker and I realized that the dockerfile uses

FROM python:2.7

Can I still use the same dockerfile contents but change it to

FROM ubuntu:14.04

and make it work with python 2.7 or 3.4 for Django 1.8.1?

With ubuntu you can run a django app. you just have to install the dependencies for it (with instructions in your Dockerfile for example).

In your Dockerfile, add something like :

RUN apt-get install python
RUN apt-get install django

You may also have to replace some commands by their equivalent if they're not implemented in the new base image (replace apt-get by pacman if you use archlinux instead of ubuntu for example).

But if you use django, you also can install and use pip.
