CassKop, the Cassandra Kubernetes operator makes it easy to run Apache Cassandra on Kubernetes. Apache Cassandra is a popular, free, open-source, distributed wide column store, NoSQL database management system. The operator allows to easily create and manage racks and data centers aware Cassandra clusters.

CassKop is based on CoreOS operator-sdk tools and APIs.

CassKop creates/configures/manages Cassandra clusters atop Kubernetes and is by default space-scoped which means that :

• CassKop is able to manage X Cassandra clusters in one Kubernetes namespace.
• You need X instances of CassKop to manage Y Cassandra clusters in X different namespaces (1 instance of CassKop per namespace).

This adds security between namespaces with a better isolation, and less work for each operator.

For detailed see the installation instructions.

The documentation of the Casskop operator project is available at the Casskop Documentation Page.

The Casskop image is automatically built and stored on Github Packages

Casskop uses standard Cassandra image (tested up to Version 3.11 and 4.0)

CassKop is build using operator SDK:

• operator-sdk
• operator-lifecycle-manager

We uses Github Action as our CI tool to build and test the operator.

To accelerate build phases we have created a custom build-image used by the CI pipeline:

See CONTRIBUTING for details on submitting patches and the contribution workflow.

Operator SDK is part of the operator framework provided by RedHat & CoreOS. The goal is to provide high-level abstractions that simplifies creating Kubernetes operators.

The quick start guide walks through the process of building the Cassandra operator using the SDK CLI, setting up the RBAC, deploying the operator and creating a Cassandra cluster.
