Fluent-Bit Chart

Fluent Bit is an open source and multi-platform Log Forwarder.

Chart Details

This chart will do the following:

• Install a configmap for Fluent Bit
• Install a daemonset that provisions Fluent Bit [per-host architecture]

Installing the Chart

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

$ helm install --name my-release stable/fluent-bit

When installing this chart on Minikube, it's required to specify that so the DaemonSet will be able to mount the log files properly, make sure to append the --set on_minikube=true option at the end of the helm command, e.g:

$ helm install --name my-release stable/fluent-bit --set on_minikube=true
