Installation options

Starting with the 1.7.0 release (May 7, 2021), the GitHub repo for the Kubernetes Operator for Apache Cassandra moved from https://github.com/datastax/cass-operator to https://github.com/k8ssandra/cass-operator. Ongoing development of the Cassandra Operator and subsequent releases have been migrated to the K8ssandra project. See the k8ssandra/cass-operator GitHub repo for more information on using the Cassandra Operator.

The Cassandra Operator is available on its own or packaged with other tools.

You can manually install cass-operator on a supported container orchestration platform.

Install on Kubernetes

Follow the kubectl commands in Quickstart for the Kubernetes Operator for Apache Cassandra. These steps also explain how to deploy a supported Apache Cassandra or DataStax Enterprise (DSE) releases to your Kubernetes cluster.

Install on Openshift

You can install cass-operator on Openshift using the Operator Lifecycle Manager (OLM) or the Openshift UI.

Openshift UI
Operator Lifecycle Manager

When running on Openshift, you can install the Cassandra Operator directly from the Openshift UI. See the Openshift documentation for information about installing operators.

cass-operator is available in the OperatorHub as a community version as well as certified version. If running outside Openshift, you can install the Cassandra Operator using the Operator Lifecycle Manager (OLM). You can find cass-operator from the OperatorHub under the name cass-operator-community. A certified version is available from the Openshift UI.

To install OLM, run the following command:

curl -sL https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.28.0/install.sh | bash -s v0.28.0

If OLM is already installed in your cluster, the Cassandra Operator can be installed with the following command:

kubectl create -f https://operatorhub.io/install/cass-operator-community.yaml

You can follow the installation progress by running the following command:

kubectl get csv -n operators

The OLM installation supports running the Cassandra Operator in a cluster scope and namespace scope settings. Use OLM to configure the Cassandra Operator deployment. If you don’t want to use OperatorHub to install the Cassandra Operator, you can also use the following bundle and catalogs for manual installation:

Install with Kustomize

See the cass-operator README for instructions and options for installing the Cassandra Operator with Kustomize.
