Kubernetes Event Exporter

Kubernetes Event Exporter allows exporting the often missed Kubernetes events to various outputs so that they can be used for observability or alerting purposes.

TL;DR

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/kubernetes-event-exporter

Introduction

This chart bootstraps a Kubernetes Event Exporter deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.12+
• Helm 3.1.0

Installing the Chart

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

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/kubernetes-event-exporter

These commands deploy Kubernetes Event Exporter on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip

: List all releases using helm list or helm ls --all-namespaces

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.

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.
