Kube-prometheus-stack

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 kube-prometheus-stack configure it easily, kube-prometheus-stack.

Rate your experience required. Comments required. The kube-prometheus-stack Helm chart installs the kube-prometheus stack. The kube-prometheus stack configures Prometheus Operator with a default Prometheus-Alertmanager-Grafana stack, and sets up preconfigured Grafana dashboards and Alertmanager alerts. It also configures a set of Prometheus scrape targets, and sets up node-exporter and kube-state-metrics. Prometheus Operator is a sub-component of the kube-prometheus stack.

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. Common examples of performance monitoring include application HTTP request response time and underlying infrastructure performance. Prometheus can collect data on HTTP response times and show if the applications are responding quickly.

Create SLOs. Dashboard list. Inbound Webhook.

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.

Prometheus Operator implements the Kubernetes Operator pattern for managing a Prometheus-based Kubernetes monitoring stack. A Kubernetes Operator consists of Kubernetes custom resources and controller code that abstract away the management and implementation details of running a given service on Kubernetes.
