Cluster configuration and deployment at Ognitio

Red Cell: Cluster Configuration & Deployment

This repository contains scripts and configurations used at Ognitio to automate the deployment process of our clusters. As we run Apache Mesos and a few of his frameworks for scheduling, we plan to continuously share publicly related templates and scripts through this directory.

Status

This project is undergoing heavy refactoring, hardening and testing and isn't even considered alpha.
