Uninstall Kubernetes Operator for Apache Cassandra and related resources in Kubernetes

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

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.

Uninstall examples

On a local machine where you have authorized access to the Kubernetes (K8s) cluster, as described in Create a Kubernetes cluster, use the following commands to remove the CassandraDatacenter, the Kubernetes Operator for Apache Cassandra, and the storage class. The examples are for a GKE 1.16 environment in which the Cassandra 3.11.7 image was deployed. Adjust the commands based on your cloud, storage, and database options.

Uninstall a deployed CassandraDatacenter from the Kubernetes cluster.

For example:

kubectl delete cassdcs --all-namespaces --all

Sample Output:

cassandradatacenter.cassandra.datastax.com "dc1" deleted

Uninstall a deployed Kubernetes Operator for Apache Cassandra from the Kubernetes cluster.

For example:

kubectl delete -f https://raw.githubusercontent.com/k8ssandra/cass-operator/v1.7.1/docs/user/cass-operator-manifests.yaml

Sample Output:

namespace "cass-operator" deleted
serviceaccount "cass-operator" deleted
secret "cass-operator-webhook-config" deleted
customresourcedefinition.apiextensions.k8s.io "cassandradatacenters.cassandra.datastax.com" deleted
clusterrole.rbac.authorization.k8s.io "cass-operator-cluster-role" deleted
clusterrolebinding.rbac.authorization.k8s.io "cass-operator" deleted
role.rbac.authorization.k8s.io "cass-operator" deleted
rolebinding.rbac.authorization.k8s.io "cass-operator" deleted
service "cassandradatacenter-webhook-service" deleted
deployment.apps "cass-operator" deleted
validatingwebhookconfiguration.admissionregistration.k8s.io "cassandradatacenter-webhook-registration" deleted

Uninstall the deployed storage class.

For example:

kubectl delete -f https://raw.githubusercontent.com/k8ssandra/cass-operator/v1.7.1/operator/k8s-flavors/gke/storage.yaml

Sample Output:

storageclass.storage.k8s.io "server-storage" deleted
