⚠️ Repo Archive Notice

As of Nov 13, 2020, charts in this repo will no longer be updated. For more information, see the Helm Charts Deprecation and Archive Notice, and Update.

fluentd

Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. Fluentd helps you unify your logging infrastructure (Learn more about the Unified Logging Layer).

DEPRECATION NOTICE

This chart is deprecated and no longer supported.

TL;DR;

$ helm install stable/fluentd

Introduction

This chart bootstraps an fluentd deployment on a Kubernetes cluster using the Helm package manager.

Installing the Chart

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

$ helm install stable/fluentd --name my-release

The command deploys fluentd 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.

Autoscaling

By enabling autoscaling the chart will use statefulset with hpa instead of deployment with PVC. Please be noted to statefulset limitation The autoscaling is disabled by default for backward compatibility

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install stable/fluentd --name my-release \
  --set=image.tag=v0.0.2,resources.limits.cpu=200m

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

$ helm install stable/fluentd --name my-release -f values.yaml

Tip

: You can use the default values.yaml
