⚠️ DEPRECATED - Fluent Bit Loki chart

This chart was moved to

This chart install the Fluent Bit application to ship logs to Loki. It defines daemonset on a Kubernetes cluster using the Helm package manager.

Installing the Chart

If you don’t have Helm installed locally, or Tiller installed in your Kubernetes cluster, read the Using Helm documentation to get started. To install the chart with the release name my-release using our helm repository:

helm repo add loki
helm upgrade --install my-release loki/fluent-bit \
    --set loki.serviceName=loki.default.svc.cluster.local

If you deploy Loki with a custom namespace or service name, you must change the value above for loki.serviceName to the appropriate value.

The command deploys Fluent Bit on the Kubernetes cluster with the default configuration. The configuration section lists the parameters that can be configured during installation.

To configure the chart to send to Grafana Cloud use:

helm upgrade --install my-release loki/fluent-bit \
    --set,loki.servicePort=80,loki.serviceScheme=https \
    --set loki.user=2830,loki.password=1234

Tip: List all releases using helm list

To install a custom tag use the following command:

helm upgrade --install my-release loki/fluent-bit \
    --set image.tag=<custom tag>

The full list of available tags on docker hub.

Alternatively you can install the full Loki stack (Loki + Fluent Bit) using:

helm upgrade --install my-release loki/loki-stack \
    --set fluent-bit.enabled=true,promtail.enabled=false

This will automatically configured the loki.serviceName configuration field to the newly created Loki instance.


By default, rbac.create is set to true. This enable RBAC support in Fluent Bit and must be true if RBAC is enabled in your cluster.

The chart will take care of creating the required service accounts and roles for Fluent Bit.

If you have RBAC disabled, or to put it another way, ABAC enabled, you should set this value to false.

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.


The following tables lists the configurable parameters of the Fluent Bit chart and their default values.
