$ helm repo add banzaicloud-stable https://kubernetes-charts.banzaicloud.com
$ helm repo update
$ helm install banzaicloud-stable/logging-operator

Introduction

This chart bootstraps an Logging Operator 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 banzaicloud-stable/logging-operator

The command deploys logging-operator 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 tables lists the configurable parameters of the logging-operator chart and their default values.
