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

Development

git clone https://github.com/openstack/puppet-ceph.git
cd puppet-ceph
sudo gem install bundler
bundle install

The developer documentation of the puppet-openstack project is the reference:

IRC channels:

  • irc.freenode.net#puppet-openstack
  • irc.oftc.net#ceph-devel

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
