In this article, I present a quick and maintainable way to set up and deploy Prometheus on Kubernetes. We will focus on deployment using Helm Charts and how to configure it easily. Prometheus is an open-source monitoring and alerting system. It has multiple tool components, including:. Helm Charts therefore help to define, install, and upgrade even the most complex Kubernetes application and allow controlling and maintain it easily by using a template where all Kubernetes deployment is defined. Here we will be working on mickrok8s k8s cluster, but it applies anywhere.

This data helps Kubernetes administrators achieve many important objectives related to system performance, resource utilization, scaling, and root cause analysis. Kubernetes does not include a built-in monitoring tool, but several tools can fill this gap with Prometheus—an open-source observability system developed at SoundCloud in and currently maintained by the CNCF—being the de-facto industry standard for monitoring Kubernetes clusters. Each component is customizable and can be installed and configured using several different methods. Kube-prometheus is a popular deployment method for the full Prometheus stack that can be easily deployed into a Kubernetes cluster. The stack is preconfigured to be highly available and collect metrics specific to Kubernetes clusters. In this article, we will review the kube-prometheus monitoring stack for Kubernetes clusters, including a walk-through of exactly how to install Kube Prometheus yourself. Kubernetes is a complex system, and cluster administrators require observability tools to monitor the health and state of the systems. Kube-prometheus can monitor system performance.

But there are customizations necessary to tailor the Helm installation for K3s , a lightweight Kubernetes installation. In this article, I will detail the necessary modifications to deploy a healthy monitoring stack on a K3s cluster. You must have a healthy rancher K3s cluster. If you follow the instructions in my K3S cluster on Ubuntu using Terraform article, then you will have a cluster like below, with If you do not have Helm3 installed, follow my article on Helm installation here. To support persistence and scheduling of the monitoring components across any node in the cluster, you need to provide an external Kubernetes storageclass. One that is accessible from any node in the cluster and has independent persistence. You could use a full-fledged cluster storage solution like longhorn , but I will prefer the nfs-subdir-external-provisioner from my article here. By default, K3s binds several of its management components to the localhost However, for monitoring we need these endpoints exposed so their metrics can be pulled by Prometheus.

I recently added monitoring and alerting to my Kubernetes stack to discover and respond to failures faster. It took me a lot longer I than expected to get my head around kube-prometheus-stack and get it doing what I wanted it to, so here's what I found out. Running these large deployments by myself has led to a lot of automation.
