Integrate an Application with Prometheus Operator and Package with a Helm Chart

Julien Acroute, July 19, 2021 08:59 AM | Source: Camptocamp Blog

In the previous posts, we saw:

  • how to implement metrics in applications
  • how to run the monitoring stack locally
  • how to test and debug metrics generated by a simple Python Flask application

In this post we will:

  • use Kubernetes Custom Resources to integrate our application with the Prometheus Operator
  • define some alerts based on the metrics generated by the application
  • deploy a custom dashboard in Grafana
  • package everything in a Helm chart, including a Grafana dashboard

Connect Prometheus to your Application

Prometheus will retrieve metrics from Pods with a /metrics HTTP endpoint. If the Prometheus Operator is deployed in your ...

How to allow dynamic Terraform Provider Configuration

Raphaël Pinson, May 11, 2021 11:47 AM | Source: Camptocamp Blog

Terraform relies heavily on the concept of providers, a base brick which consists of Go plugins enabling the communication with an API.

Each provider gives access to one or more resource types, and these resources then manage objects on the target API.

Most of the time, a provider's configuration is static, e.g.

provider "aws" {
  region = "us-east-1"
}

However, in some cases, it is useful to configure a provider dynamically, using the attribute values from other resources as input for the provider's configuration.

I'll use the example of the Argo CD provider. In a single Terraform run ...

Terraform Project Design — A parallel with Puppet

Mickaël Canévet, May 03, 2021 11:57 AM | Source: Camptocamp Blog

Introduction

Like Puppet, Terraform provides low-level objects written in a programming language that allows you to manage individual resources.

With Puppet, these low-level objects, the Puppet Types and Providers, written in Ruby, allow you to apply the CRUD paradigm to resources located on managed nodes.

With Terraform, these low-level objects, the Terraform Resources, written in Go, allow you to apply the CRUD paradigm to resources in an API.

On top of this, both solutions provide a DSL: the Puppet DSL for Puppet and the HashiCorp Configuration Language (HCL) for Terraform. They are both declarative languages, allowing ...

Puppet Tip 119 - Hiera merge behavior

Anonymous, February 11, 2021 12:00 AM | Source: Example 42

Hiera v5 allows you to provide information regarding merge behavior in a couple of different ways. Using different merge behaviors allows you to e.g. separate common (admin) users from application users by adding common users in common hiera layer and the application users into an application hiera layer. This reduces duplicates in data and allow more simple data management. Another example is installation of packages. You usually have a list of packages you need on all systems (admin packages) and some packages which are needed on special systems only. Again you can mention all common packages in hiera common laxer ...

Digging out data in style with puppet 4.5.0

Unknown (noreply@blogger.com), January 11, 2021 02:46 PM | Source: Puppet on the Edge

In Puppet 4.5.0 there are a couple of new functions dig, then and lest that together with the existing assert_type and with functions makes it easy to do a number of tasks that earlier required conditional logic and temporary variables.

You typically run into a problem in programming languages in general when you are given a data structure consisting of hashes/arrays (or other objects), and you need to “dig out” a particular value, but you do not know if the path you want from the root of the structure actually exists.

Say you are given a hash like this: ...

Slicing and dicing Forge usage data

Anonymous, December 11, 2020 12:00 AM | Source: binford2k.com

The Forge content ecosystem is large and complex. There are a lot of modules, and modules that use resources from other modules. It can be hard to navigate these relationships when you’re deciding how to invest development resources. For example, it’s useful to know how many modules call a function when deciding whether we should deprecate it.

To assist in making these decisions, the Ecosystem program maintains a publicly accessible database that can help you weigh the costs of some of these decisions. You can use the data directly using the BigQuery console, or if your need is simply ...

How to update the PostgreSQL version on your puppetserver

admin, October 19, 2020 01:04 PM | Source: Immerda Techblog

Our puppetserver uses puppetdb which users PostgreSQL as the persistent datastore in the back.
So far everything is self-contained on the same VM and PostgreSQL is more less managed by the puppetdb module.
The puppetdb module takes care of setting up the PostgreSQL server and uses the upstream PostgreSQL yum module for the binaries. By default it uses PostgreSQL in version 9.6.

Lately, it was announced that puppetdb will start requiring PostgreSQL at least in version 11. Time to start to upgrade our PostgreSQL installation to be ready.

Since the upstream yum repository allows to install multiple version in parallel ...

Porting a module to RHEL 8

Anonymous, October 02, 2020 12:00 AM | Source: binford2k.com

Often, updating a Puppet module to work on a newer platform is mostly a case of fixing up a a few paths or package names. Sometimes though, more significant changes are called for. When updating to RHEL (or family) 8, here are some major changes that we’ve had to account for:

  • dnf is the new standard package manager.
  • Some services only log to systemd now and not to /var/log/*
  • X.org has finally been superseded by Wayland.
  • iptables had been replaced with nftables.
  • The default Python version is now 3.x.
  • Replacing ntpd with the new chrony service. Yes, that means ...
