Installation

There are multiple ways to install the Stackable Operator for Apache Zookeeper. stackablectl is the preferred way but Helm is also supported. OpenShift users may prefer installing the operator from the RedHat Certified Operator catalog using the OpenShift web console.

  • stackablectl (recommended)

  • Helm

stackablectl is the command line tool to interact with Stackable operators and our recommended way to install Operators. Follow the installation steps for your platform.

After you have installed stackablectl, use it to install the ZooKeeper Operator and its dependencies:

stackablectl operator install \
  commons=0.0.0-dev \
  secret=0.0.0-dev \
  listener=0.0.0-dev \
  zookeeper=0.0.0-dev

The tool will show

Installed commons=0.0.0-dev operator
Installed secret=0.0.0-dev operator
Installed listener=0.0.0-dev operator
Installed zookeeper=0.0.0-dev operator
Consult the Quickstart to learn more about how to use stackablectl. For example, you can use the --cluster kind flag to create a Kubernetes cluster with kind.

You can also use Helm to install the Operators. Add the Stackable Helm repository:

helm repo add stackable-dev https://repo.stackable.tech/repository/helm-dev/

Then install the Stackable Operators:

helm install --wait commons-operator stackable-dev/commons-operator --version 0.0.0-dev
helm install --wait secret-operator stackable-dev/secret-operator --version 0.0.0-dev
helm install --wait listener-operator stackable-dev/listener-operator --version 0.0.0-dev
helm install --wait zookeeper-operator stackable-dev/zookeeper-operator --version 0.0.0-dev

Helm deploys the operators in Kubernetes Deployments and applies the CRDs for the ZooKeeperCluster Stacklet.

What’s next?

Use the operator to deploy a ZooKeeper Stacklet.
