Zookeeper requires a persistentVolumeClaim, and the helm chart isn't editable after install becase statefulsets are immutable.

So, install a hostpath-provisioner or nfs provisioner via helm for this particular example.

helm upgrade --install hostpath-provisioner --namespace kube-system rimusz/hostpath-provisioner

Alternatively, you can manually provision hostpath volumes as shown in the YAML file.

Greate work by cetic getting Nifi helmified ! Other then the statefulset issue for ZK which needs a volume, it deploys as is out of the box.

helm repo add cetic https://cetic.github.io/helm-charts
helm repo update
