Introduction

This chart bootstraps kube-state-metrics on Kubernetes using the Helm package manager.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Looking to use Kube State Metrics in production? Try VMware Application Catalog, the enterprise edition of Bitnami Application Catalog.

Prerequisites

  • Kubernetes 1.19+
  • Helm 3.2.0+

Installing the Chart

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

helm install my-release bitnami/kube-state-metrics

The command deploys kube-state-metrics 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 release:

helm delete 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 the following command sets the replicas of the kube-state-metrics Pods to 2.

helm install my-release --set replicas=2 bitnami/kube-state-metrics

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

helm install my-release -f values.yaml bitnami/kube-state-metrics

Tip: You can use the default values.yaml

Configuration and installation details

Rolling vs Immutable tags

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.

Use Sidecars and Init Containers

If additional containers are needed in the same pod (such as additional metrics or logging exporters), they can be defined using the sidecars config parameter. Similarly, extra init containers can be added using the initContainers parameter.

Refer to the chart documentation for more information on, and examples of, configuring and using sidecars and init containers.

Set Pod affinity

This chart allows you to set custom Pod affinity using the affinity parameter. Find more information about Pod's affinity in the Kubernetes documentation.

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters.

Troubleshooting

Upgrading

helm upgrade my-release bitnami/kube-state-metrics

To 3.0.0

This major release renames several values in this chart and adds missing features, in order to be aligned with the rest of the assets in the Bitnami charts repository.

Affected values:

  • service.port was renamed as service.ports.metrics.
  • service.nodePort was renamed as service.nodePorts.metrics.
  • securityContext was split in podSecurityContext and containerSecurityContext.
  • Removed unused value rbac.apiVersion.

To 2.0.0

This version updates kube-state-metrics to its new major, 2.0.0. There have been some value's name changes to acommodate to the naming used in 2.0.0:

  • .Values.namespace -> .Values.namespaces
  • .Values.collectors -> .Values.kubeResources

For more information, please refer to kube-state-metrics 2 release notes.

To 1.1.0

This version introduces bitnami/common, a library chart as a dependency. More documentation about this new utility could be found here. Please, make sure that you have updated the chart dependencies before executing any upgrade.

To 1.0.0

On November 13, 2020, Helm v2 support formally ended. This major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
