# Node Exporter
[Node Exporter](https://github.com/prometheus/node_exporter) is a Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.
## TL;DR;
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install bitnami/node-exporter
```
## Introduction
This chart bootstraps [Node Exporter](https://github.com/bitnami/bitnami-docker-node-exporter) on [Kubernetes](http://kubernetes.io) using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters.
## Prerequisites
- Kubernetes 1.12+
- Helm 2.11+ or Helm 3.0+
## Installing the Chart
Add the `bitnami` charts repo to Helm:
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
```
To install the chart with the release name `my-release`:
```bash
$ helm install --name my-release bitnami/node-exporter
```
The command deploys Node Exporter on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
## Uninstalling the Chart
To uninstall/delete the `my-release` release:
```bash
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
## Parameters
The following table lists the configurable parameters of the Node Exporter chart and their default values.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example the following command sets the `minReadySeconds` of the Node Exporter Pods to `120` seconds.
```bash
$ helm install --name my-release --set minReadySeconds=120 bitnami/node-exporter
```
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```bash
$ helm install --name my-release -f values.yaml bitnami/node-exporter
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
## Upgrading
```bash
$ helm upgrade my-release bitnami/node-exporter
```

** Please be patient while the chart is being deployed **
Watch the Node Exporter DaemonSet status using the command:
kubectl get ds -w --namespace {{ .Release.Namespace }} -l app.kubernetes.io/name={{ template "node-exporter.name" . }},app.kubernetes.io/instance={{ .Release.Name }}
