zookeeper-operator

Zookeeper Operator Helm Chart

Installs Zookeeper Operator to create/configure/manage Zookeeper clusters atop Kubernetes.

Introduction

This chart bootstraps a Zookeeper Operator deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.15+ with Beta APIs
• Helm 3.2.1+

Installing the Chart

To install the zookeeper-operator chart, use the following commands:

$ helm repo add pravega https://charts.pravega.io
$ helm repo update
$ helm install [RELEASE_NAME] pravega/zookeeper-operator --version=[VERSION]

• [RELEASE_NAME] is the release name for the zookeeper-operator chart.
• [DEPLOYMENT_NAME] is the name of the zookeeper-operator deployment so created. (If [RELEASE_NAME] contains the string zookeeper-operator, [DEPLOYMENT_NAME] = [RELEASE_NAME], else [DEPLOYMENT_NAME] = [RELEASE_NAME]-zookeeper-operator. The [DEPLOYMENT_NAME] can however be overridden by providing --set fullnameOverride=[DEPLOYMENT_NAME] along with the helm install command)
• [VERSION] can be any stable release version for zookeeper-operator from 0.2.8 onwards.

This command deploys a zookeeper-operator on the Kubernetes cluster in its default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the zookeeper-operator chart, use the following command:

$ helm uninstall [RELEASE_NAME]

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