# kube-state-metrics Helm Chart



* Installs the [kube-state-metrics agent](https://github.com/kubernetes/kube-state-metrics).

Installs the [kube-state-metrics agent](https://github.com/kubernetes/kube-state-metrics).



## Installing the Chart

## Get Repo Info



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

```console

helm repo add kube-state-metrics https://kubernetes.github.io/kube-state-metrics

helm repo update

```



_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._



## Install Chart



```console

# Helm 3

$ helm install [RELEASE_NAME] kube-state-metrics/kube-state-metrics [flags]



# Helm 2

$ helm install --name [RELEASE_NAME] kube-state-metrics/kube-state-metrics [flags]

```



_See [configuration](#configuration) below._



_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._



## Uninstall Chart



```console

# Helm 3

$ helm uninstall [RELEASE_NAME]



# Helm 2

# helm delete --purge [RELEASE_NAME]

```



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



_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._



```bash

$ helm install stable/kube-state-metrics

## Upgrading Chart



```console

# Helm 3 or 2

$ helm upgrade [RELEASE_NAME] kube-state-metrics/kube-state-metrics [flags]

```



_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._



### From stable/kube-state-metrics



You can upgrade in-place:



1. [get repo info](#get-repo-info)

1. [upgrade](#upgrading-chart) your existing release name using the new chart repo

kube-state-metrics is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects.

The exposed metrics can be found here:

https://github.com/kubernetes/kube-state-metrics/tree/master/Documentation#documentation.

https://github.com/kubernetes/kube-state-metrics/blob/master/docs/README.md#exposed-metrics



The metrics are exported on the HTTP endpoint /metrics on the listening port.

In your case, {{ template "kube-state-metrics.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local:{{ .Values.service.port }}/metrics

In your case, {{ template "kube-state-metrics.fullname" . }}.{{ template "kube-state-metrics.namespace" . }}.svc.cluster.local:{{ .Values.service.port }}/metrics



They are served either as plaintext or protobuf depending on the Accept header.

They are designed to be consumed either by Prometheus itself or by a scraper that is compatible with scraping a Prometheus client endpoint.
