How GitHub used catalog difference analysis with octocatalog-diff to complete its zero-downtime Puppet 4 upgrade and migration to Puppet Server.
Anonymous, 1 week | Source: Example 42With the release of Puppet 4.9, version 5 of Hiera has landed on our Puppet servers, introducing some very interesting evolutions. Hiera is Puppet’s builtin key/value data lookup system, which has some peculiar characteristics: It’s hierarchical: We can configure different hierarchies of data sources and these are traversed in order to find the value of the desired key, from the layer at the top, to the one at the bottom It has a modular backend system: data can be stored on different places, according to the used plugins, from simple Yaml or Json files, to MongoDb ...

Puppet training courses available at PuppetConf 2017: Intro to Puppet; Puppetizing Infrastructure; and Puppet Fundamentals, Practitioner & Architect.
Anonymous, 2 weeks | Source: Example 42Think about the following situation: You have a node running in development environment. A user logs in and runs puppet agent --test --environment production. What will happen: the node will receive production ready code. This is OK… but… what if you use the environment to also pass data like passwords, users, accounts to your nodes? In this case the development system will have all production data and users are happy that they now can connect to your production database. If you would not like to allow this, you have to make use of an external nodes classifier (ENC). An ENC ...
rnelson0, 2 weeks, 3 days | Source: RNELSON0Over the past three years, my Puppet for vSphere Admins series has meandered through a number of topics, mostly involved on the Puppet side and somewhat light on the vSphere side. That changed a bit with my article Make the Puppet vRealize Automation plugin work with vRealize Orchestrator, describing how to use the plugin’s built-in […]
Anonymous, 3 weeks | Source: Example 42GitLab is a versatile Open Source tool to manage your code repositories. It’s often used on premise to host private code projects, something like a private GitHub. We often use it to host our Puppet code and we have started to appreciate its multiple features, one of them is the integrated CI engine. It’s incredibly easy to use and powerful, you can design your CI pipeline in a file called .gitlab-ci.yml at the root directory of your control repo. GitLab will automatically interpret it whenever there are changes in your repo code, and try to use GitLab ...
rnelson0, 1 month, 1 week | Source: RNELSON0Last 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 […]
rnelson0, 1 month, 2 weeks | Source: RNELSON0The Roles and Profiles pattern by Craig Dunn is a very common pattern used by Puppet practitioners. I’ve written about it before. 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 […]
rnelson0, 1 month, 2 weeks | Source: RNELSON0I have been using Puppet Enterprise at work and Puppet OpenSource at home for a few years now. There’s a lot to love about both products, but since work uses PE and new features tend to land there first, I have been thinking about trying PE at home as well. I don’t have a large […]

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

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 ...

My 2017 redhat summit talk Button Push Deployments With Integrated Red Hat Open Management got accepted. I have the big honor of sharing the talk not just with my last years co presenter Michael Dahlgren but also with Red Hat EMEA’S configuration management extraordinaire Maxim Burgerhout.
As we combine our talks you can expect an awesome mixture of different demos and showcases around Red Hat Open Management.

About a month ago I blogged about Choria Playbooks – a way to write series of actions like MCollective, Shell, Slack, Web Hooks and others – contained within a YAML script with inputs, node sets and more.
Since then I added quite a few tweaks, features and docs, it’s well worth a visit to choria.io to check it out.
Today I want to blog about a major new integration I did into them and a major step towards version 1 for Choria.

I’m old school and still rocking an old X220 laptop because I didn’t like the new ones. My battery life isn’t as great as I’d like it to be, but it gets worse when some “webapp” (which I’d much rather have as a native GTK+ app) causes Firefox to rev my CPU with their websocket (hi gmail!) poller.
This seems to happen most often on planes or when I’m disconnected from the internet. Since it’s difficult to know which tab is the offending one, and since I might want to keep that tabs ...

Today I am very pleased to release something I’ve been thinking about for years and actively working on since August.
After many POCs and thrown away attempts at this over the years I am finally releasing a Playbook system that lets you run work flows on your MCollective network – it can integrate with a near endless set of remote services in addition to your MCollective to create a multi service playbook system.
This is a early release with only a few integrations but I think it’s already useful and I’m looking for feedback and integrations to build ...

Some time ago I mentioned that I am working on improving the MCollective Deployment story.
I started a project called Choria that aimed to massively improve the deployment UX and yield a secure and stable MCollective setup for those using Puppet 4.
The aim is to make installation quick and secure, towards that it seems a common end to end install from scratch by someone new to project using a clustered NATS setup can take less than a hour, this is a huge improvement.
Further I’ve had really good user feedback, especially around NATS. One user reports 2000 nodes ...

I previously published “A revisionist history of configuration management“. I meant for that to be the intro to this article, but it ended up being long enough that it deserved a separate post. I will explain Send/Recv in this article, but first a few clarifications to the aforementioned article.
I mentioned that my “revisionist history” was inaccurate, but I failed to mention that it was also not exhaustive! Many things were left out either because they were proprietary, niche, not well-known, of obscure design or simply for brevity. My apologies if you were involved with Bcfg2, Bosh, Heat ...
