Tip of the Week 25 - The PSICK Developer Environment Setup - PDES

Anonymous, 0 minutes | 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 ...

Tip of the Week 25 - Control Repo documentation

Anonymous, 6 days, 13 hours | Source: Example 42

The current method to manage documentation in Puppet code is based on puppet strings. We can install it as a gem: puppet resource package puppet-strings provider=puppet_gem and then, from within the main directory of a module we can generate the module documentation just by running: puppet strings Puppet strings uses Yard, a Ruby Documentation Tool that parses comments with defined @tags in the code and creates documentation based on them. For example,we can document a class by adding lines as the following at the beginning of its manifest: # @summary This class manages the general hardening of a system ...

Tip of the Week 24 - Puppet 5

Anonymous, 1 week, 6 days | Source: Example 42

Puppet 5 was scheduled to be released somewhere near May 2017. The release was postponed due to some CVE on existing supported Puppet versions. So we expect Puppet 5 to be available quite soon. Therefore it will be soon time to work on Puppet 5 updates. Most important is to mention that Puppet 5 does not require any Puppet code changes. It is still recommended to update to latest Puppet 4 version prior upgrading to Puppet 5. The packages layout and directory structure has not changed. Agent and Master still install into /opt/puppetlabs. Hardware requirements are also identical to ...

Tip of the Week 23 - Puppet reports and metrics

Anonymous, 2 weeks, 6 days | Source: Example 42

Any Puppet infrastructure must be monitored and needs log checking. For monitoring we can re-use existing solutions like cacti, checkmk, icinga, monit, munin, nagios, sensu, zabbix see also Wikipedia. Every puppet agent has locally stored important information for your puppet infrastructure. Most of these informations are stored inside the statedir. puppet agent --configprint statedir /opt/puppetlabs/puppet/cache/state tree /opt/puppetlabs/puppet/cache/state /opt/puppetlabs/puppet/cache/state |- classes.txt |- graphs |- last_run_report.yaml |- last_run_summary.yaml |- resources.txt |- state.yaml \- transactionstore.yaml One wants to check not only for running puppet agent, but also for proper catalog retrieval.

Testing multiple Puppet versions with TravicCI (and allowing failures)

Dean Wilson (dwilson@unixdaemon.net), 3 weeks, 2 days | 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), 3 weeks, 4 days | 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, 1 month, 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 ...

vRealize Orchestrator Workflows for Puppet Enterprise

Last week, I moved the home lab to Puppet Enterprise. One of the things I love about PE is the Console. However, I am a member of Vox Pupuli and we develop Puppetboard (the app AND the module) so it is convenient for me to use it and tie it into PE as well. Though […]

What goes in a Puppet Role or Profile?

One of the most common questions I see is, what goes into a Role or Profile class? Craig’s article provides some guidelines, specifically these two:   A role includes one or more profiles […]

Metaparameters in mgmt

purpleidea, 3 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

R.I. Pienaar, 4 months, 1 week | Source: R.I.Pienaar - www.devco.net

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 ...
