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 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 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.
Setup
Implementation
A 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
Use Cases
- I want to try this module, heard of ceph, want to see it in action
- I want to operate a production cluster
- I want to run benchmarks on three new machines
Development
git clone https://github.com/openstack/puppet-ceph.git
cd puppet-ceph
sudo gem install bundler
bundle install

Beaker Integration Tests
Relies on rspec-beaker and tests are in spec/acceptance. It also requires Vagrant and Virtualbox .
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 \
bundle exec rspec spec/acceptance
