Is There a Docker Configurator for Rails Apps?

Docker has this library of images that pretty much anyone can push to right but the problem with that is there's so many options now and it's hard to understand the difference in all of them then.

There's just easier ways than like go find the image that somebody else built right yeah and it's funny to use Docker because they should really be thinking about the customer problem rather than
