Puppet module for Riak

This module allows you to manage Riak with puppet.

Riak is a Dynamo-inspired key/value store that scales predictably and easily. Riak combines a decentralized key/value store, a flexible map/reduce engine, and a friendly HTTP/JSON query interface to provide a database ideally suited for Web applications. And, without any object-relational mappers and other heavy middleware, applications built on Riak can be both simpler and more powerful. For complete documentation and source code, see the Riak home page at Basho.

Getting Started

Have a look at the Wiki.

Tested on:

You need to ssh and run 'gem install hiera-puppet' after launch.

• Ubuntu 12.04 LTS (Precise) 64-bit - works,
• Debian 6.0 (Squeeze) 64-bit
• CentOs 6.0 64-bit

Development Environment

You can simply clone this module like normal to your puppet-modules-folder. It'll work. Done.

If you want to check that it works, then install vagrant, rake and VirtualBox, then run rake vagrant:up.

Outstanding External Issues

Working on this module has been really nice, but unfortunately it's noticeable that not most people actually unit-test their puppet modules.

I think puppet is an awesome project, and I would love for the tooling around creating powerful modules to improve. Here are some of my experienced bumps in the road.

• https://github.com/rodjek/rspec-puppet/issues/44

This issue affects the tests, making them impossible to run cleanly together at the moment. The only way around it, is to launch rspec first for classes, then for functions.

• https://github.com/rubyist/guard-rake/issues/12

This issue is solved by Joerg, but he hasn't submitted a pull request, so I've cloned his repository and am using my own clone of that, until the issue is resolved (about 4 lines of code) in master. Affects running of rake when the task raises errors.

• http://projects.puppetlabs.com/issues/15820

This issue is what is currently failing all of spec/classes/. A fix HAS been released, but not as a gem. The repository doesn't allow me to report issues conveniently, and there's no gemspec file, so I can't just reference the repo either.

• https://github.com/amfranz/rspec-hiera-puppet/issues/3

This issue affects a single test that exposed the issue; overriding puppet variables with rspec variables. The test is currently marked as pending.

• https://gist.github.com/3560970

Unmet dependencies on vanilla Debian 6.0. I'm probably going to have to make apt-get add a source for this OS.

• no such gem 'hiera-puppet' - I can't provision out of the box with Puppet 2.7, because the hiera-puppet module fails with an import error. This gem should be bundled with puppet, or there ought to be a way to make the module install it.

• Problem building and pushing module:

   xyz@co-data:~/labs/puppet-riak$ puppet module build .
   Error: undefined method `provide' for nil:NilClass
   Error: Try 'puppet help module build' for usage

Similar to

* http://projects.puppetlabs.com/issues/14962
* https://github.com/alup/puppet-rbenv/issues/27
* http://projects.puppetlabs.com/issues/4416

And it might be that fixing #4248 solves the problem, since I'm forced to do require File.join(File.dirname(__FILE__), '/../util/erly') at the time of writing.
