Fluent Operator Helm chart

Fluent Operator provides a Kubernetes-native logging pipeline based on Fluent-Bit and Fluentd.

Installation

To install or upgrade Fluent Operator using Helm:

export FLUENT_OPERATOR_CONTAINER_RUNTIME="containerd" # or "cri-o", "docker" depending on the container runtime being used (see `values.yaml`)

helm repo add fluent https://fluent.github.io/helm-charts
helm upgrade --install fluent-operator fluent/fluent-operator \
  --create-namespace \
  --set containerRuntime=${FLUENT_OPERATOR_CONTAINER_RUNTIME}

By default, all CRDs required for Fluent Operator will be installed. To prevent helm install from installing CRDs, you can set fluent-bit.crdsEnable or fluentd.crdsEnable to false.

Upgrading

Helm does not manage the lifecycle of CRDs, so if the Fluent Operator CRDs already exist, subsequent chart upgrades will not add or remove CRDs even if they have changed. During upgrades, users should manually update CRDs:

wget https://github.com/fluent/fluent-operator/releases/download/<version>/fluent-operator.tgz
tar -xf fluent-operator.tgz
kubectl replace -f fluent-operator/crds

Chart Values

helm show values fluent/fluent-operator
