Dockerfile to automated build

[ProgEsteves]

It would be a good idea publish a Dockerfile to automate the project build in a repository, like Docker Hub.

I try this here:
https://hub.docker.com/r/progesteves/sql_exporter

But I think you need an official Dockerfile.

[Apologies for taking so long to respond, I wasn't aware I needed to watch my own projects to get notified of new issues so I never got notified of this.]

Hey Felipe, thanks for contributing the Dockerfile. I've created an automated build on Docker Hub and linked it from the README. If you want to add a brief description of how to run the image in Docker, I'm more than happy to merge it in. My experience with Docker is limited to a tutorial I ran through once.
