In a previous blog post, we introduced use cases for separating configuration data from Puppet code. This post (part one of a two part series) will go in-depth with installing, configuring, and using Hiera, but let’s first look at WHY we would need Hiera. Introduction to the SSH module One of the benefits of Hiera […]

You’ve bought Pro Puppet, downloaded a couple of modules from the Puppet Forge (and have written some of your own too), and you’re on your way to implementing your Puppet environment when it hits you: something feels bulky with the way you’ve designed your Puppet code. Your modules may not be portable between environments (development, […]

One of the issues that crops up when working with Puppet is ensuring that your manifests do what you expect. Errors are bound to happen. A missed brace can make a manifest not compile, or forgetting to include a module or set a variable may mean that running Puppet on the host fails to enforce […]

The first Puppet Triage-a-thon was a huge success. Thank you so much to everyone who attended and contributed! Some of our favorite stats from the event: We started the day with 2292 open tickets. Over the course of the day 565 tickets were triaged. We also closed 115 tickets. That’s almost 25% of the open […]

Written in conjunction with Tino Vazquez from the OpenNebula Project, and cross-posted on the OpenNebula blog. Puppet is used for managing the infrastructure for many IaaS software packages, including Eucalyptus, OpenStack, and OpenNebula. OpenNebula is an IaaS manager which can not only manage a large amount of different virtualization and public cloud platforms, it can […]

The Puppet CloudFormation Face integrates Puppet Enterprise (PE) with CloudFormation so that users can reliably create entire Puppet Enterprise “stacks” in Amazon’s EC2 from their workstation. A “stack” refers to a collection of launched Amazon Web Services (AWS) “resources” that can be specified as a “template” in CloudFormation’s declarative json modeling language. Templates support a […]

With the launch of Puppet Enterprise 2.0, it’s easy to get lost in the scale of what we’ve enabled sysadmins to do. Besides shipping a world-class configuration management tool, we now make it easy to create managed servers from thin air. In addition, we’re providing command line tools that take fresh OS installs directly to […]

With the release of Puppet Enterprise 2.0, Puppet Labs has added cloud provisioning capabilities with support for some of the most popular public and private cloud offerings including Amazon EC2 and VMware. PE 2.0 allows you to quickly provision virtual machines and start managing them with Puppet right away. Getting Started The following set of […]

Why do we want configuration management? There are plenty of reasons, but at the core of them is that we want to streamline the configuration and deployment of systems. We want this process to be repeatable, well-understood, and predictable. We want to make it deterministic. Determinism — the idea that a process should result in […]

It’s come time for us to pick a code name for our next release of Puppet. If you help develop Puppet you may be fairly familiar with our naming system, but for those who haven’t yet contributed to the open source project, we name each version of Puppet after a Muppet. We use code names […]

This post is the second in a series on Live Management, new in Puppet Enterprise 2.0, a capability that lets you visually discover, clone, and manage resources across your entire deployment, all through the graphical interface (GUI). In the first post in this series we covered how to make quick changes across your infrastructure by […]

VMware, Google Ventures, and Cisco have joined existing investors Kleiner Perkins Caufield & Byers, True Ventures, and Radar Partners in our $8.5 million Series C financing.

OVERVIEW We have discovered a security vulnerability (“AltNames Vulnerability”) whereby a malicious attacker can impersonate the Puppet master using credentials from a Puppet agent node. This vulnerability cannot cross Puppet deployments, but it can allow an attacker with elevated privileges on one Puppet-managed node to gain control of any other Puppet-managed node within the same […]

Puppi was developed to standardize different procedures of web app deployments and has evolved into a shell command that provides quick actions useful for sysadmins.

After I wrote an article for the OpenBSD Journal about my job at M:Tier explaining how we were deploying OpenBSD in several production setups, I’ve been asked several times to extend the part regarding our usage of Puppet. Most of our solution management is handled by Puppet, from unattended installation and configuration to daily maintenance […]

Since starting at Puppet Labs four months ago, many friends have asked me why. “Puppet is a systems tool, right? Isn’t it all command line? Where’s the user experience? Don’t you usually work on the web? Are you designing their website?” To the contrary, I’m happy to say that for the first time since the […]
