Anonymous, 13 hours, 46 minutes | Source: Example 42Hiera-eyaml is a Hiera backend which can be used to encrypt single keys in Hiera yaml files. It has become the standard the facto to manage passwords, secrets and confidential data in Puppet. It’s now included by default in Hiera 5, (shipped with Puppet version > 4.9), in earlier versions in can be installed as a gem: gem install hiera-eyaml On the Puppet server we need to do that also in Puppet environment: puppetserver gem install hiera-eyaml To configure it we need to specify the backend in hiera.yaml and the location of the keys used to encrypt ...

New open source Puppet Development Kit helps you develop Puppet modules faster, with best practices & module testing built in. Also, Windows tools.
Anonymous, 1 week | Source: Example 42When we develop our Puppet code it’s useful to have the possibility to test the effect of what we are doing on real systems, running Puppet on them, using our code under development, and seeing what happens without the need to commit anything. Traditional testing methods based on spec tests don’t verify the actual effect of our code on systems (they analyse the generated catalog to verify if it has the expected resources), we need to run real code on real operating systems. Vagrant is the perfect tool for this and we can use it in our Puppet ...

Anonymous, 2 weeks | Source: Example 42There are words that we, well I, sometimes use with hesitation: we are not 100% sure about their meaning, especially when they are in a foreign language. Puppet class indirection is one of these. It’s the name I give to the pattern I’m going to describe in these lines, but I’m not fully sure that’s a correct one. Anyway, I already happened to write about class indirection driven via Hiera, let’s review here the key principles and see some use case. We are used, with Puppet, to include classes which contain other classes. It happens ...
Michael Arnold, 2 weeks, 6 days | Source: The Razor's EdgeToday, I have released a large update to my Red Hat network Puppet module to the Puppet Forge. Numerous pull requests were merged including: Added support for promiscuous interfaces. (Elyse Salberg) Added a parameter to disable restart of network service on change. (Evgeni Golov) Added support for netmask and broadcast parameters in alias range. (Nick […]
Anonymous, 3 weeks | Source: Example 42With Puppet 4.10.5 and 5.0.2 a fix for a missing functionality was released: sort_merged_arrays lookup option. In earlier versions of Puppet this was named ‘sort_merge_arrays’ but lacked the functionality. Unluckily Puppet did not build the fix with backward compatibility. When using ‘sort_merge_arrays’ the following will happen: Puppet 4.10.4/5.0.1 or earlier: success - but no functionality Puppet 4.10.5/5.0.2 or later: compiler failure When using ‘sort_merged_arrays’ the following will happen: Puppet 4.10.4/5.0.1 or earlier: compiler failure Puppet 4.10.5/5.0.2 or ...
Michael Arnold, 3 weeks, 5 days | Source: The Razor's EdgeOver the past month I have been adding much needed support for running Puppet with strict_variables = true to all of the RazorsEdge Puppet modules. Thanks to coreone, I finally had a solution that did not require tearing out the legacy global variable support. As much as I think that continued inclusion of global variable […]

Before Puppet 4.0.0 there was basically only the data types; String, Boolean, Array, Hash, and Undef. Most notably missing were numeric types (Numeric, Integer, and Float). In Puppet 4.0.0 those and many other types were defined and implemented in a proper type system. This was all good, but a few practical problems were not solved; namely data conversion. In Puppet 4.5.0 there is a new feature that will greatly help with this task. But first lets look at the state of what is available in prior versions.

When it comes to running automated tests of my public Puppet code TravisCI has long been my favourite solution. It’s essentially a zero infrastructure, second pair of eyes, on all my changes. It also doesn’t have any of my local environment oddities and so provides a more realistic view of how my changes will impact users. I’ve had two Puppet testing scenarios pop up recently that were actually the same technical issue once you start exploring them, running tests against the Puppet version I use and support, and others I’m not so worried about.
This use ...

As part of refreshing my old puppet modules I’ve started to convert some of my Puppet templates from the older ERB format to the newer, and hopefully safer, Embedded Puppet (EPP).
While it’s been a simple conversion in most cases, I did quickly find myself lacking the ability to select a template based on a hierarchy of facts, which I’ve previously used multitemplate to address. So I wrote a Puppet 4 version of multitemplate that wraps the native EPP function, adds matching lookup logic and then imaginatively called it multi_epp. You can see an example of it ...

Recently, while operating two different remote-controlled appliances, I realized that it was high time for a discussion about declarative and imperative paradigms. Let’s start by looking at the two remotes:
At first glance you will notice that one of these remotes is dark, and the other is light. You might also notice that my photography skills are terrible. Neither of these facts is very important to the discussion at hand. Is there anything interesting that ...
