Fluentd Elasticsearch

• Installs Fluentd log forwarder.

TL;DR;

$ helm install stable/fluentd-elasticsearch

Introduction

This chart bootstraps a Fluentd daemonset on a Kubernetes cluster using the Helm package manager. It's meant to be a drop in replacement for fluentd-gcp on GKE which sends logs to Google's Stackdriver service, but can also be used in other places where logging to ElasticSearch is required. The used Docker image also contains Google's detect exceptions (for Java multiline stacktraces), Prometheus exporter, Kubernetes metadata filter & Systemd plugins.

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 stable/fluentd-elasticsearch

The command deploys fluentd-elasticsearch 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.
