Prometheus Node Exporter


$ helm install stable/prometheus-node-exporter


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.


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,

$ helm install --name my-release \
  --set  \

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/prometheus-node-exporter
You can’t perform that action at this time.
