Logging operator Chart

Logging operator Managed centralized logging component fluentd and fluent-bit instance on cluster.

tl;dr:

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

Introduction

This chart bootstraps a 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

CRDs

Use createCustomResource=false with Helm v3 to avoid trying to create CRDs from the crds folder and from templates at the same time.

The command deploys Logging operator on the Kubernetes cluster with 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 Kubernetes components associated with the chart and deletes the release.

Configuration

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

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

$ helm install --name my-release -f values.yaml banzaicloud-stable/logging-operator

Tip: You can use the default values.yaml

Installing Fluentd and Fluent-bit via logging

The previous chart does not install logging resource to deploy Fluentd and Fluent-bit on cluster. To install them please use the Logging Operator Logging chart.

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