Kafka-operator chart

Kafka-operator is a Kubernetes operator to deploy and manage Kafka resources for a Kubernetes cluster.

Prerequisites

Kubernetes 1.15.0+

Installing the chart

Before installing the chart, you must first install the kafka-operator CustomResourceDefinition resources. This is performed in a separate step to allow you to easily uninstall and reinstall kafka-operator without deleting your installed custom resources.

kubectl apply --validate=false -f https://github.com/banzaicloud/kafka-operator/releases/download/v0.12.3/kafka-operator.crds.yaml

To install the chart:

$ helm repo add banzaicloud-stable https://kubernetes-charts.banzaicloud.com
$ helm install kafka-operator --create-namespace --namespace=kafka banzaicloud-stable/kafka-operator

To install the operator using an already installed cert-manager

$ helm install kafka-operator --set certManager.namespace=<your cert manager namespace> --namespace=kafka  --create-namespace banzaicloud-stable/kafka-operator

Upgrading the chart

To upgrade the chart since the helm 3 limitation you have to set a value as well to keep your CRDs. If this value is not set your CRDs might be deleted.

helm upgrade kafka-operator --set crd.enabled=true --namespace=kafka banzaicloud-stable/kafka-operator

Uninstalling the Chart

To uninstall/delete the kafka-operator release:

$ helm delete --purge kafka-operator

The command removes all the Kubernetes components associated with the chart and deletes the release.
