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 the 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=25.7.0 \
  secret=25.7.0 \
  listener=25.7.0 \
  zookeeper=25.7.0

The tool prints

Installed commons=25.7.0 operator
Installed secret=25.7.0 operator
Installed listener=25.7.0 operator
Installed zookeeper=25.7.0 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.

helm repo subcommands are not supported for OCI registries. The operators are installed directly, without adding the Helm Chart repository first.

Install the Stackable Operators:

helm install --wait commons-operator oci://oci.stackable.tech/sdp-charts/commons-operator --version 25.7.0
helm install --wait secret-operator oci://oci.stackable.tech/sdp-charts/secret-operator --version 25.7.0
helm install --wait listener-operator oci://oci.stackable.tech/sdp-charts/listener-operator --version 25.7.0
helm install --wait zookeeper-operator oci://oci.stackable.tech/sdp-charts/zookeeper-operator --version 25.7.0

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.
