Cleaning up unused modules with Dropsonde

Anonymous, September 01, 2022 12:00 AM | Source: binford2k.com

You’ve probably been using Puppet Forge modules to manage bits in your infrastructure for years. And if you’re like most of us, you’ve gradually added more modules and maybe sort of lost track of exactly what some of them do and on what nodes they’re declared on. You may even suspect that you have modules installed that you haven’t actually used in years…. only you’re not quite certain which modules those might be. I’m certainly guilty of that!

You won’t be surprised to know that one of our most common customer requests is a way to audit their modules to ...

Modern Puppet node classification

Martin Alfke, August 08, 2022 06:35 AM | Source: betadots

Within Puppet we use modules to describe specific technical components which we want to configure on a system.
This can by achieved either by upstream library modules (some refer to these as component modules) which can be found on Puppet Forge or by self written Puppet code which we usually refer to as technical implementation profiles.

Since Puppet is a client server model, the server must be aware of each node and must know which classes a node needs. This process is called node classification.

Within Puppet there are several ways how nodes can be classified.
This article describes the ...

Moderne Puppet Node Klassifizierung

Martin Alfke, August 08, 2022 06:34 AM | Source: betadots

Innerhalb von Puppet werden mit Hilfe von Modulen bestimmte technische Komponenten konfiguriert.
Module können Upstream entwickelt und auf der Puppet Forge zur Verfügung gestellt werden. Diese Module nennen wir gerne Bibliotheken oder Komponenten Module.
Alternativ handelt es sich um selbst geschriebene Technische Implementierungs-Profile.

Da es sich bei Puppet um ein Client-Server Modell handelt, muss der Server wissen, welche Module auf einem System zum Einsatz kommen sollen. Diesen Vorgang nennt man Node Klassifizierung.

Innerhalb von Puppet stehen unterschiedliche Varianten für die Node Klassifizierung zur Verfügung.
Dieser Artikel beschreibt die klassische Node Klassifizierung und ihre Einschränkungen und geht danach auf flexiblere, Hiera ...

Puppet Evaluation Error. Error while evaluating a Resource Statement - Unknown resource type

Anonymous, August 07, 2022 12:00 AM | Source: Example 42

So you got the Error while evaluating a Resource Statement, Unknown resource type with Puppet and are searching for solutions? You are lucky, because right now we are going to see what it means, why it happens and how to solve it. TL;DR The module that provides the referred Unknown resource type is not available where your Puppet code is compiled. Find the module you need in the metadata.json file of the module where the code fails (refer to the provided file path). Solve by adding the dependency module to your Puppetfile, or running the puppet module install command. Decomposing ...

How I deployed a serverless and high availability Blackbox Exporter on AWS Fargate

Hugo Bollon, July 04, 2022 02:19 PM | Source: Camptocamp Blog

At Camptocamp, we're using multiple Blackbox Exporters hosted in a few different cloud providers and world regions. We're using them to monitor availability and ssl certificate validity and expiration of many websites.
They were all deployed inside Linux VMs provisioned by Terraform and configured by our Puppet infrastructure. However, in order to achieve more simplicity and high availability, we wanted to deploy containers instead of these VMs.

� Why a serverless approach with AWS Fargate

AWS ECS (Elastic Container Service) is a fully managed, highly scalable and docker compatible container orchestration service.
It is widely used to host microservice ...

Extending Puppet CA

Martin Alfke, July 04, 2022 09:48 AM | Source: betadots

Puppet encrypts connections using a self-signed OpenSSL based CA.
Usually a Puppet CA has a validity of 5 years. At initial Installation one can configure the ca_ttl setting:

puppet config set --section server ca_ttl 10y

Existing installations can extend the CA e.g. by using the following script which has been made public by Neeloy on Puppet Community Slack channel:

cd /etc/puppetlabs/puppet/ssl/ca
(openssl rsa -noout -modulus -in ca_key.pem  2> /dev/null | openssl md5 ; openssl x509 -noout -modulus -in ca_crt.pem  2> /dev/null | openssl md5 )
# Generate new CSR
openssl x509 -x509toreq -in ca_crt.pem -signkey ca_key.pem -out ca_csr.pem
# Sign ...

HashiConf Europe 2022 - Vibes from a perfect conference

Anonymous, June 22, 2022 12:00 AM | Source: Example 42

IT conferences are main attractions in our jobs with machines, the occasions to meet again remote friends you’ve known for years, know people with whom you have something in common and stay updated on vendors’ products. After the last two years I guess many of us are looking forward to attend some good in presence conference, hence my decision to plan a road trip, from Italy to Amsterdam, take the occasion to meet business partners, old friends and, first time for me, jump into an HashiCorp conference. How tp always matters I didn’t came to the party without anything, I ...

Verlängerung der Puppet CA

Martin Alfke, April 10, 2022 05:59 PM | Source: betadots

Puppet verschlüsselt Verbindungen mit einer selbst-signierten OpenSSL basieten CA.
Diese hat üblicherweise eine Laufzeit von 5 Jahren. Bei der initialen Installation kann man dies über eine Konfigurationseinstellung ändern:

puppet config set --section server ca_ttl 10y

Bei Bestandsinstallationen kann man die CA im laufenden Betrieb verlängern.
Im Slack Puppet Community Channel hat Neeloy z.B. ein Script veröffentlicht:

cd /etc/puppetlabs/puppet/ssl/ca
(openssl rsa -noout -modulus -in ca_key.pem  2> /dev/null | openssl md5 ; openssl x509 -noout -modulus -in ca_crt.pem  2> /dev/null | openssl md5 )
# Generate new CSR
openssl x509 -x509toreq -in ca_crt.pem -signkey ca_key.pem -out ca_csr.pem

Towards a Modular DevOps Stack

Raphaël Pinson, February 23, 2022 05:37 PM | Source: Camptocamp Blog

A year and a half ago, our infrastructure team at Camptocamp was faced with an increasingly problematic situation. We were provisioning more and more Kubernetes clusters, on different cloud providers. We used Terraform to deploy the infrastructure itself, and we had started to adopt Argo CD to deploy applications on top of the cluster.

We quickly ended up with many projects using similar logic, often borrowed from older projects, and most of these cluster were starting to use divergent code.

Diverging projects

We thought it was time to put together a standard core in order to:

  • provision Kubernetes clusters;
  • deploy standard applications ...

Winter Solstice run 2021

Anonymous, December 21, 2021 12:00 AM | Source: binford2k.com

Today at 7:58 am was the Winter Solstice. That’s when the days stop getting shorter and start getting longer again. Metaphorically, it’s when darkness starts leaving our lives again and we welcome in more light.

Ruben and I celebrated with a 7:58 am morning run, of course. The first half of the run was on a well-worn regular route, but then on the way back we wandered on an unplanned, unmapped, unfamiliar route. We just let ourselves go where our feet and Ruben’s nose led us. It was wonderful. I thought about things I’d like to let go of and ...

2021-10-21: A Fond Farewell For Now to Community Day & Norman

michaeltlombardi, October 20, 2021 12:00 AM | Source: Puppet IAC Team

IAC Community Day

Background

The Infrastructure Automation Content (IAC) team formed from the merger of 4 core content-focused teams (Modules, Windows, Cloud & Containers, and Networking), maintaining forty-five open-source supported Puppet modules and over a dozen tools that help reduce the content maintenance and support costs.

A crucial part of Puppet’s success has always been the support of the community. The IAC team, like with all module teams before, would have had a dedicated engineer or engineers assigned to community triage, usually on a rotational basis.

The triage rota consumed 20% of the team’s engineering resources. It was challenging due ...
