The error message that puppet hackers are probably most familiar is:
Error: Duplicate declaration: Thing[/foo/bar] is already declared in file /tmp/baz.pp:2; cannot redeclare at /tmp/baz.pp:4 on node computer.example.com
Typically this means that there is either a bug in your code, or someone has defined something more than once. As annoying as this might be, a compile error happens ...

Last November I was contacted by Llewellyn Rozario, Acquisition Editor from Packt Publishing, asking me to write a book about Puppet.
That has been an unexpected and welcomed surprise, I’ve never written a book and hardly considered the opportunity to write one, but the idea seemed too much appealing to be dismissed.
The editor requested a book about how to extend Puppet functionalities with Ruby code, but in my own opinion there where some more interesting topics to talk about.
I proposed a completely revised table of contents and a different title.
I wanted to write about all the ...
Anonymous, 4 weeks | Source: People & Software#Learning Puppet at the Puppet Pizza Place In this set of blog posts, I will teach you the base concepts of the [puppet DSL](http://puppetlabs.com/puppet). Most of the time Puppet is taught within the context of IT configuration management. I've chosen not to do so. I've chosen baking pizza's as the learning environment. It helps less technical people, like IT managers, for example, to get the concepts of Puppet. ## Pietro's Puppet Pizza Place Pietro was worn out. He'd had a very busy day at his pizza place. Business was going well. Too ...

In the first part of this blog series I expressed my opinions about these points:
I also underlined two fundamental issues that I think are still open in the Puppet modules ecosystem:
Some preliminary exploration on the first topic has been expressed in Part 1. There’s much more to do ...

And I'm back!! It has been a long 3 months for me. For those who is not aware, I've been in the UAE working on-site for a client project. It is a very challenging project for a *nix Systems Administrator like me because the project was to automate a large number of Windows applications for a client. Windows! The first thing that came into my mind was the horror of using Windows but at the same time I'm rather excited because it is an uncharted domain for both me and OlinData as we've never work with ...
Henrik Lindberg (email@example.com), 1 month | Source: Puppet on the EdgeOptionally Typed Parameters
And now, the latest entry in the series about the new Puppet Type System introduces the capability to optionally type the parameters of defines, classes, lambdas and EPP template parameters.
There are also some new abilities and changes to the type system that I will cover in this post.
Writing high quality puppet code involves judicious use of type checking of given arguments. This is especially important when writing modules that are consumed by others. Anyone having written a serious module knows that it is a chore to not only deal with all of ...
Henrik Lindberg (firstname.lastname@example.org), 1 month | Source: Puppet on the EdgeThe Puppet Type System
In Puppet 3.5's future parser there is a new type system that makes it much easier to write validation logic for parameters (and much more). I have written a series of blog posts about the new type system - and this post is just an index to the series.
It works best if they are read in the order they were published:

Configuration management is an essential part of securing your infrastructure because it can make sure that it is set up correctly. It is essential that configuration management only enhance security, and not weaken it. Unfortunately, the status-quo of secret management in puppet is pretty poor.
In the worst (and most common) case, plain text passwords are found in manifests. If the module author tried harder, sometimes these password strings are pre-hashed (and sometimes salted) and fed directly into the consumer. (This isn’t always possible without modifying the software you’re managing.)
On better days, these strings are kept separate ...

This is a repost of an article I wrote for the Acquia Blog some time ago.
As mentioned before, devops can be summarized by talking about culture, automation, monitoring metrics and sharing. Although devops is not about tooling, there are a number of open source tools out there that will be able to help you achieve your goals. Some of those tools will also enable better communication between your development and operations teams.
When we talk about Continuous Integration and Continuous Deployment we need a number of tools to help us there. We need to be able to build reproducible ...

Earlier this year, R.I.Pienaar released his brilliant data in modules hack, a few months ago, I got the chance to start implementing it in Puppet-Gluster, and today I have found the time to blog about it.
What is it?
R.I.’s hack lets you store hiera data inside a puppet module. This can have many uses including letting you throw out the nested mess that is commonly
params.pp, and replace it with something file based that is elegant and hierarchical. For my use case, I’m using it to build OS independent puppet modules, without storing ...

I’m somehow obsessed by Puppet modules, it must be a rare syndrome, and I hope self awareness is the first step towards its cure.
I’ve passed years developing modules, trying to find ways to make them useful, usable and reusable. Most of the times I wrote them while working on specific Puppet projects, trying to figure out how they could be used in different circumstances.
I’ve redefined my opinions on how to design them over time, following the evolution of Puppet, the best practices of the moment, the feedback I received from other users and my own ...

With Puppet 3.6 out the door and the new caching mechanisms it provides I started exploring how to do caching with Puppet. A thank you goes out to Ken Barber of Puppet Labs and Erik Dalén of Spotify for their help on this quest.
The first thing I wanted to do is use the new caching mechanism for directory based environments on Puppet 3.6 in such a way that our production environment would be cached forever. Of course we also need a way to invalidate that cache when we deploy but between two deploys this code never ever ...

On the puppet module forge we find a lot of modules (around 2400 at the time I'm writing this). However, anyone who has looked around the puppet forge has figured out that a lot of these modules are of questionable quality, and that's putting it nicely.
In the puppet fundamentals training we give, there's a chapter about the puppet forge. One of the questions i always get is "how can I distinguish the good modules from the bad ones?". The problem is that there's not a single answer to that question. However, there are a number ...
