Add a Dockerfile

Actually, I would rather see a Vagrantfile there because it seems like this app is deployed along with https://github.com/elementary/website. I don't think we should use Docker unless we plan to deploy using it.

The site is actually deployed on bare metal without any docker or vagrant file. It's all done with ansible.

The reason I would add a Dockerfile for travis ci testing. It's also nice for quick development, and so people now how to setup a proper environment.

There's a Vagrantfile in #40 which is supposed to reproduce the deployment environment. It has Sphinx working so far and of course the current reimplementation in Vala.

Alright. I'm going to update this and say using a Dockerfile would be really nice. I'm planning on using the new Kubernetes Digital Ocean service for the elementary infrastructure. Creating a Dockerfile for valadoc would allow us to have travis run a cron task that could auto deploy valadoc.

[arteymix]

I fully agree.

If we use docker-compose, we can setup Sphinx as well and minimize the work needed to get a running instance locally.

With the Valum backend, you could even add a robust HTTP server (i.e. nginx) for facing the Web and deliver resources, and communicate internally using SCGI.
