Tip of the Week 29 - PSICK explained

Anonymous, 4 days, 2 hours | Source: Example 42

Using PSICK for the very first time confuses people as they are confronted with a highly flexible approach for managing and configuring their infrastructure. This posting will give you a guidance on how to read, understand and use PSICK. Normally system administrators strictly follow the approach of writing roles and profiles which consist of lots of Puppet code, describing the infrastructure. With PSICK one has the possibility of using or adopt a predefined role/profile pattern. Let’s get to the content: why PSICK set up NTP configure SSH manage users Why PSICK?

Tip of the Week 28 - Puppet and Fabric

Anonymous, 1 week, 4 days | Source: Example 42

Fabric is a remote execution tool, written in Python, which ease parallel execution and orchestration of commands on different nodes. Why does it matter with Puppet? Because it’s a good candidate, and not a rare choice, to trigger Puppet runs (and more) from a central location. In PSICK, our Puppet control-repo [generator], we use it for several tasks tasks which are related to the whole Puppet code workflow, from development, to testing and deployment. We can install Fabric, as common with Python software, using pip: pip install fabric Once installed we have at disposal the fab executable, which reads ...

Converting and Formatting Data Like a Pro With Puppet 4.5.0

Henrik Lindberg (noreply@blogger.com), 2 weeks | Source: Puppet on the Edge

Before Puppet 4

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.

Managing SSH server security with Puppet

Tip of the Week 27 - Puppet node classification options

Anonymous, 2 weeks, 4 days | Source: Example 42

When using a Puppet Agent - Puppet Master setup it is required that the Puppet Master has information about classes which a node should receive. This process is called Node Classification. There are several possible ways on how to do this. This posting will cover several different options Node Classification in Puppet environment manifests Node classification in Hiera Node classification on external sources Node Classification in Puppet environment manifests The most cenvenient way to classify nodes is using Puppet environment manifests data.

Tip of the Week 26 - The PSICK Developer Environment Setup

Anonymous, 3 weeks, 4 days | Source: Example 42

Working on Puppet code with least possible effort requires a properly setup of a suitable workstation environment. Usually everybody starts playing around with different sets of utilities and tools, learning the hard way about the best usable setup. This article will guide you to a setup, providing a proper basis for initially working with PSICK, Puppet or Ruby in general. Puppet Development is based on Ruby. The first thing we need is a Puppet recommended Ruby version. As version can change from release to release, therefor we need some flexibility on Ruby versions being available. Puppet provides a website with ...

Testing multiple Puppet versions with TravicCI (and allowing failures)

Dean Wilson (dwilson@unixdaemon.net), 1 month, 2 weeks | Source: Dean Wilson@UnixDaemon

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.

Announcing multi_epp - Puppet function

Dean Wilson (dwilson@unixdaemon.net), 1 month, 2 weeks | Source: Dean Wilson@UnixDaemon

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 ...

Declarative vs. Imperative paradigms

purpleidea, 2 months, 2 weeks | Source: The Technical Blog of James

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:

declarative-imperative

Two different “remotes”. The one on the left operates a television, and the one on the right controls a central heating and cooling system.

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 ...

Metaparameters in mgmt

purpleidea, 4 months, 3 weeks | Source: The Technical Blog of James

In mgmt we have meta parameters. They are similar in concept to what you might be familiar with from other tools, except that they are more clearly defined (in a single struct) and vastly more powerful.

In mgmt, a meta parameter is a parameter which is codified entirely in the engine, and which can be used by any resource. In contrast with Puppet, require/before are considered meta parameters, whereas in mgmt, the equivalent is a graph edge, which is not a meta parameter. [1]

Kinds

As of this writing we have seven different kinds of meta parameters:

Choria Update

Recently at Config Management Camp I’ve had many discussions about Orchestration, Playbooks and Choria, I thought it’s time for another update on it’s status.

I am nearing version 1.0.0, there are a few things to deal with but it’s getting close. Foremost I wanted to get the project it’s own space on all the various locations like GitHub, Forge, etc.

Inevitably this means getting a logo, it’s been a bit of a slog but after working through loads of feedback on Twitter and offers for assistance from various companies I decided to ...
