Uninstall Kubernetes Operator for Apache Cassandra and related resources in Kubernetes

Uninstalling the resources shown in this topic deletes the workloads, the pods, and all the data associated with the deployments, including all Cassandra or DSE databases and their data. Before uninstalling, verify that you have accounted for any and all dependencies with apps and users of the resources.

To uninstall Kubernetes Operator for Apache Cassandra and related resources in Kubernetes, use the kubectl delete command.

On a local machine where you have authorized access to the Kubernetes (K8s) cluster, use the following commands to remove the CassandraDatacenter, the Kubernetes Operator for Apache Cassandra, and the storage class.

The following examples are for a GKE 1.16 environment where the Cassandra 3.11.7 image was deployed. Adjust the commands based on your cloud, storage, and database options.

kubectl delete cassdcs --all-namespaces --all
