Create a Docker containter for Akvo DASH python development

[iperdomo]

We're going to use Django as a way of exposing some Models via the Django Rest Framework. In the past we used a Vagrant Box for development but we're moving towards using Docker.

We need to prepare a Dockerfile, and documentation on how to use it, that describes an image for development. Initially will be just one image containing everything needed for development.

• django 1.9.1
• python 3
• postgres 9.5
• nginx

With docker, it makes sense to not have a virtualenv, right? If so then just having pip is enough I think. Eventually it'd be nice to have python libraries auto-install from a requirements file, but that's not needed initially.

Not entirely sure about the version of python. 3.5 was released only a few months ago so there is a small chance of libraries not supporting it. 3.4 is over a year old and the conservative choice I guess.

Default versions in Ubuntu 14.04

• python 3.4 - http://packages.ubuntu.com/trusty/python3
• pip 1.5.4 http://packages.ubuntu.com/trusty/python-pip

Yeah, the virtualenv is the workaround to have a self contained environment. In this case the whole image is the isolated environment.

Ah, well, then 3.4 seems like an obvious easy choice!

Do we need Nginx if it's only for development?

[zzgvh]

Good question. But given the time pressure we seem to have it's probably good if a dev server can be set up using this for demo purposes.
