A quick introduction to Prometheus and Alertmanager

We'll continue the trend of using Helm as the installation mechanism. Prometheus' Helm Chart is maintained as one of the official Charts. You can find more info in the project's README (https://github.com/helm/charts/tree/master/stable/prometheus). If you focus on the variables in the Configuration section (https://github.com/helm/charts/tree/master/stable/prometheus#configuration), you'll notice that there are quite a few things we can tweak. We won't go through all the variables. You can check the official documentation for that. Instead, we'll start with a basic setup, and extend it as our needs increase.

Let's take a look at the variables we'll use as a start.

 1  cat mon/prom-values-bare.yml

The output is as follows.

server:
  ingress:
    enabled: true
    annotations:
      ingress...
