Quick start

Create custom storage class

We recommend to use a custom StorageClass to leverage the volume binding mode WaitForFirstConsumer

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: exampleStorageclass
parameters:
  type: pd-standard
provisioner: kubernetes.io/gce-pd
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer

tip

Remember to set your NiFiCluster CR properly to use the newly created StorageClass.

As a pre-requisite NiFi requires Zookeeper so you need to first have a Zookeeper cluster if you don't already have one.

We believe in the separation of concerns principle, thus the NiFi operator does not install nor manage Zookeeper.

Install Zookeeper

To install Zookeeper we recommend using the Bitnami's Zookeeper chart.

helm repo add bitnami https://charts.bitnami.com/bitnami

helm install zookeeper bitnami/zookeeper \
    --namespace=zookeeper \
    --set resources.requests.memory=256Mi \
    --set resources.requests.cpu=250m \
    --set resources.limits.memory=256Mi \
    --set resources.limits.cpu=250m \
    --set global.storageClass=standard \
    --set networkPolicy.enabled=true \
    --set replicaCount=3 \
    --create-namespace

warning

Replace the storageClass parameter value with your own.

Deploy NiFi cluster

And after you can deploy a simple NiFi cluster.

# Add your zookeeper svc name to the configuration
kubectl create -n nifi -f config/samples/simplenificluster.yaml
