stable/fluentd/README.md
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 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).
This chart is deprecated and no longer supported.
$ helm install stable/fluentd
This chart bootstraps an fluentd deployment on a Kubernetes cluster using the Helm package manager.
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.
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.
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
The following table lists the configurable parameters of the fluentd chart and their default values.

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
