Introduction

The Puppet OpenStack modules were written as a collaborative effort between operators deploying OpenStack environments.

Puppet Modules

Puppet modules for the OpenStack project are hosted on StackForge.

The following Puppet modules exist:

Branches

The master branch of each modules corresponds to the master branch of the current OpenStack core projects. Once released, a new branch will be created and should be considered stable.

For example, the current master branch of stackforge/puppet-keystone is for grizzly, once released a new grizzly branch will be created, from that point onward the master branch should target the Havana release.

Releases

Master version of the modules will be released as a new major version to Puppet Forge (forge.puppetlabs.com) when its related version of OpenStack is released.

Each version of OpenStack will have a related release on the forge (fosom = 1.x, grizzly = 2.x)

When patches are accepted against a branch targeting a stable version, this will trigger a new release to that module on the forge.

NOTE: the automatic triggered forge releases still have not been setup, this process will have to be manual until this is completed.

Supported Platforms

The following OS/version are supported by the modules:

Fedora 18
RHEL 6.4
Ubuntu 12.04 (Precise)
Debian 7.0 (Wheezy)

The modules have been primarily tested on Puppet 2.7.x and Ruby 1.8.7, although they are also being used with Puppet 3.1.x, 3.0.x, with Ruby 1.9.3.

Puppet 2.6.x is currently supported, but that support will be dropped soon b/c it has been EOL'ed by PuppetLabs

Getting Help

Mailing list

In general, the mailing list is preferred, because it makes the information more readily available so that others who have the same question can search for and find those answers.

You can read and subscribe to the mailing list here: https://groups.google.com/a/puppetlabs.com/forum/#!forum/puppet-openstack

puppet-openstack@puppetlabs.com

IRC

You can talk to us directly in IRC on the #puppet-openstack channel. (freenode.net)

IRC logs can be found here.

Reporting bugs

We are using Launchpad for bugs and features tracking. Issues and requests should be submitted under the Puppet OpenStack project.

Developer documentation

Contributing to the modules

Getting Started

We follow the same process as all of the other OpenStack projects.

To contribute, the following docs contain enough information to get started:

go to : settings > watched projects and add the puppet projects (all of the form stackforge/puppet-*)

How code gets merged

Code is merged based on the voting process of the modules in Gerrit. All submitted patches automatically trigger a job that runs its rspec-puppet tests. This job is considered to be a gate in that no code is allowed to be merged that does not pass these tests. The results of this job are listed for every patch as a +1 Verified vote from Jenkins.

Any users can +/- 1 a commit and add comments on commit, but only members of the puppet-manager-core group have the ability to +2 and approve code to be merged.

Puppet OpenStack CI, and SmokeStack are two continuous integration environments that can be used to verify that any given patch can be used to deploy a functional multi-node environments. The integration of both of these systems is an ongoing process, so failures should be followed up on, but are not considered blockers at this moment.

Patches

Patches waiting to be merged can be viewed in Gerrit e.g. for stackforge/puppet-keystone

https://review.openstack.org/#/q/status:open+project:stackforge/stackforge/puppet-keystone,n,z

Q. How do I go about submitting a patch for a released branch, what the correct process? Unless is not relevant all patches should be approved for the master branch before you submit them for a stable branch. This ensures we maintain stability in the stable branches and functionality

Downloading a local patch

Clone the relevant module from StackForge, ex:

    git clone git://github.com/stackforge/puppet-openstack

in the patch, find the git checkout or cherry-pick command, and copy it:

    git fetch https://review.openstack.org/stackforge/puppet-openstack refs/changes/52/29452/9 && git checkout FETCH_HEAD

if you wanted to update an existing patch:

make a topic branch:

   git checkout -b my_topic

make your changes:

   hack,hack,hack

amend the current commit:

   git commit --amend .

now resubmit:

   git review

Rspec puppet tests

Rspec puppet tests are a requirement for getting code merged into the StackForge modules.

The best reference for getting started with rspec-puppet can be found here

Running local tests

The following command can invoked from any if the modules' directories to run their rspec puppet tests.

It assumes that both bundler as well as rubygems (and ruby) are already installed on the system.

mkdir vendor
export GEM_HOME=vendor
bundle install
# bundle exec rake -T
bundle exec rake spec

This relies on the file .fixtures.yaml to install all of the external module required for testing. The urls in this file use the git:// protocol, so this may need to be updated if you are behind a proxy.

stable branches

Master of the modules should be targeting the trunk of openstack as soon as a release is announced.

When this happens, a stable branch is created for any previous releases.

   ie: stable/grizzly

It is the responsibility for the patch submitted to know if their patch should be backported to previous stable branches.

 The general process for this can be found here: https://wiki.openstack.org/wiki/StableBranch#Workflow
