Overview

The ceph module is intended to leverage all Ceph has to offer and allow for a wide range of use case. Although hosted on the OpenStack infrastructure, it does not require to sign a CLA nor is it restricted to OpenStack users. It benefits from a structured development process that helps federate the development effort. Each component is unit tested and an integration test shows that it performs as expected when used with a realistic scenario.

Module Description

The ceph module deploys a Ceph cluster ( MON, OSD ), the Cephfs file system and the RadosGW object store. It provides integration with various environments ( OpenStack ... ) and components to be used by third party puppet modules that depend on a Ceph cluster.
