Introduction

This chart creates an Elasticsearch-Exporter deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.8+ with Beta APIs enabled

Installing the Chart

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

$ helm install --name my-release stable/elasticsearch-exporter

The command deploys Elasticsearch-Exporter on the Kubernetes cluster using 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 --purge my-release

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

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
    --set key_1=value_1,key_2=value_2 \
    stable/elasticsearch-exporter

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

# example for staging
$ helm install --name my-release -f values.yaml stable/elasticsearch-exporter

Tip: You can use the default values.yaml
