Disabling rubocop and upgrading to PDK 1.6.0

rnelson0, 2 weeks, 6 days | Source: RNELSON0

As I lamented in my article on converting to the PDK, I really do not like Rubocop and was disappointed I could not turn it off. Thankfully, that was addressed in PDK-998 and the fix was included in time for PDK 1.6.0! Disabling it is pretty simple and though it’s strictly a fix to pdk-templates, […]

Tip of the Week 78 - What you need to know about Puppet facts. Part 5 - facter.conf

Anonymous, 3 weeks, 1 day | Source: Example 42

Creating your first Puppet Task for Puppet Enterprise

rnelson0, 1 month | Source: RNELSON0

At PuppetConf 2017, Puppet Tasks were introduced as part of the new project Bolt. A task allows you to run a program on an arbitrary number of nodes. The program can be just about anything, it just needs to be written in a language that the target nodes can run. For Linux, that means pretty […]

Convert a Puppet module from Bundle-based testing to the Puppet Development Kit (PDK)

rnelson0, 1 month, 1 week | Source: RNELSON0

A few years ago, I set up my modules with a bundle-based test setup and modulesync and wrote a companion blog post. Since that was written, a lot of things have changed with puppet. One of those is the release last year of the Puppet Development Kit (PDK). The goal of the PDK is to […]

Choria Progress Update

R.I. Pienaar, 2 months, 3 weeks | Source: R.I.Pienaar - www.devco.net

It’s been a while since my previous update and quite a bit have happened since.

Choria Server

As previously mentioned the Choria Server will aim to replace mcollectived eventually. Thus far I was focussed on it’s registration subsystem, Golang based MCollective RPC compatible agents and being able to embed it into other software for IoT and management backplanes.

Over the last few weeks I learned that MCollective will no longer be shipped in Puppet Agent version 6 which is currently due around Fall 2018. This means we have to accelerate making Choria standalone in it’s own right ...

Adding rich object data types to Puppet

R.I. Pienaar, 3 months, 2 weeks | Source: R.I.Pienaar - www.devco.net

Extending Puppet using types, providers, facts and functions are well known and widely done. Something new is how to add entire new data types to the Puppet DSL to create entirely new language behaviours.

I’ve done a bunch of this recently with the Choria Playbooks and some other fun experiments, today I’ll walk through building a small network wide spec system using the Puppet DSL.

Overview


A quick look at what we want to achieve here, I want to be able to do Choria RPC requests and assert their outcomes, I want to write tests using the Puppet ...

Self-documenting Puppet modules with puppet-strings

rnelson0, 7 months, 1 week | Source: RNELSON0

Documentation is hard. Anyone who has been in IT long enough will have tales of chasing their tails because of incorrect or outdated docs, or even missing docs. Documentation really benefits from automation and ease of creation. For Puppet modules, there exists a tool called puppet-strings that can help with this. There are probably other […]

Managing multiple puppet modules with modulesync

Dean Wilson (dwilson@unixdaemon.net), 8 months | Source: Dean Wilson@UnixDaemon

With the exception of children, puppies and medical compliance frameworks managing one of something is normally much easier than managing a lot of them. If you have a lot of puppet modules, and you’ll eventually always have a lot of puppet modules, you’ll get bitten by this and find yourself spending as much time managing supporting functionality as the puppet code itself.

Luckily you’re not the first person to have a horde of puppet modules that share a lot of common scaffolding. The fine people at Vox Pupuli had the same issue and maintain an excellent tool ...
