Why it may be useful to anyone?
Prometheus Operator makes the management of Prometheus based monitoring stack easier. But as a consequence of that simplicity, new CustomResourceDefinitions appear in your k8s cluster.
Quoting official docs: The Prometheus Operator introduces additional resources in Kubernetes to declare the desired state of a Prometheus and Alertmanager cluster as well as the Prometheus configuration. The resources it introduces are:
- Prometheus
- Alertmanager
- ServiceMonitor
but there's also PrometheusRule and PodMonitor.
If you simply deliver your monitoring stack by running
kubectl apply -f bundle.yaml
from the official Prometheus Operator Github repo, or by using Helm chart, you wouldn't find anything interesting in this repository.
But, if you're using Terraform to manage your infrastructure, then it can be quite useful, as it delivers custom Provider Plugin for Prometheus Operator custom resources.
Content of /kubernetes folder is taken from official Terraform Kubernetes provider.
