• Installs prometheus node exporter

TL;DR;

Introduction

This chart bootstraps a prometheus node exporter deployment on a Kubernetes cluster using the Helm package manager.

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/prometheus-node-exporter

The command deploys node exporter on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.
