Seagate has just publicly announced 8TB HDD’s in a 3.5″ form factor. I decided to do some rough calculations to understand the density a bit better…
Note: I have decided to ignore the distinction between Terabytes (TB) and Tebibytes (TiB), since I always work in base 2, but I hate the -bi naming conventions. Seagate is most likely announcing an 8TB HDD, which is actually smaller than a true 8TiB drive. If you don’t know the difference it’s worth learning.

Purging SSH authorized keys used to be the number one top-voted ticket in the Puppet issue tracker. A community member Felix Frank has solved the issue by adding a purge_ssh_keys parameter to the User resource. The change was merged into the master branch in March 2014 and was released in Puppet 3.6.0 and with some additional bug fixes in Puppet 3.6.2.
Let’s take at the look at the code to enable this feature. Here we have a user resource for the root user. All we need to do is set the purge_ssh_keys attribute to true ...

It's been a long time coming but I'm happy to announce the release of puppet-lint 1.0.0!
Along with a bunch of bugfixes and a rewrite of most of the code, there's some (hopefully) exciting new features in this release.
Previewed in the 0.4.0 pre-release, simple problems can now be automatically fixed by puppet-lint (some problems require complex refactoring and so puppet-lint won't attempt anything on your behalf).
In 1.0.0, problems detected by the following checks can be automatically fixed
by running puppet-lint with

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 ...

It comes up every now and then in #puppet on IRC. Someone comes in, usually fairly new to Puppet, and pastes the link to a Gist with a manifest they’re having trouble with.
When you click on that link and look at it you’re usually greeted by Puppet code trying to replicate a shell script. Everything is ordered, notify/subscribes aren’t used and a ton of exec’s are in place that take care of restarting the managed services every single time.
The problem here is two-fold; people generally don’t bother to read the documentation or ...

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 ...

I also underlined two fundamental issues that I think are still open in the Puppet modules ecosystem:

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 ...

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 ...

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.

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 ...
