CentOs Version

[alexrovner]

CentOs is a fairly popular enterprise OS and as such would be great to include the centos version:

I can create a pull to incorporate the changes, just need to know how to best organize the multiple images.

Thanks for the suggestion @alexrovner, I have no objections incorporating the changes. I'm curious, is there a specific benefit to using CentOS over the existing one with Docker?

I think the easiest way to to have both, would be to split the images into a base image with the OS-specific packages, and have a generic Druid Dockerfile that builds on whichever OS image one chooses to use. Not sure if Docker provides an easy way to switch out base-images dynamically, but at least users would have the option.
