Overview
|
|
--------
|
|
|
|
The ceph module is intended to leverage all [Ceph](http://ceph.com/) 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 feature is tested with integration tests involving virtual machines to show that it performs as expected when used with a realistic scenario.

|
Module Description
|
|
------------------
|
|
|
|
The ceph module deploys a [Ceph](http://ceph.com/) cluster ( MON, OSD ), the [Cephfs](http://ceph.com/docs/next/cephfs/) file system and the [RadosGW](http://ceph.com/docs/next/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.

Setup
|
|
-----
|
|
|
|
Implementation
|
|
--------------
|
|
|
|
A [blueprint](https://wiki.openstack.org/wiki/Puppet-openstack/ceph-blueprint) contains an inventory of what is desirable. It was decided to start from scratch and implement one module at a time.
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
We follow the OS compatibility of Ceph. With the release of infernalis this is currently:
|
|
|
|
* CentOS 7 or later
|
|
* Debian Jessie 8.x or later
|
|
* Ubuntu Trusty 14.04 or later
|
|
* Fedora 22 or later
|
|
|
|

Beaker Integration Tests
|
|
------------------------
|
|
|
|
Relies on
|
|
[rspec-beaker](https://github.com/puppetlabs/beaker-rspec)
|
|
and tests are in spec/acceptance.
|
|
It also requires [Vagrant and Virtualbox](http://docs-v1.vagrantup.com/v1/docs/getting-started/)
|
|
.
|
|
|
|
```
|
|
bundle install
|
|
bundle exec rspec spec/acceptance
|
|
```
|
|
|
|
The BEAKER_set environment variable contains the resource set of linux
|
|
distribution configurations for which integration tests are going
|
|
to be run. Available values are
|
|
|
|
* two-centos-70-x64
|
|
* centos-70-x64
|
|
* two-ubuntu-server-1404-x64
|
|
* ubuntu-server-1404-x64
|
|
|
|
The default is
|
|
|
|
```
|
|
BEAKER_set=two-ubuntu-server-1404-x64 \
