Destroy a Doris Cluster

This document describes how to destroy Doris clusters on Kubernetes.

Destroy a Doris cluster managed by DorisCluster#

To destroy a Doris cluster managed by DorisCluster, run the following command:

kubectl delete dc ${cluster_name} -n ${namespace}

If you deploy the monitor in the cluster using DorisMonitor, run the following command to delete the monitor component:

kubectl delete dorismonitor ${doris_monitor_name} -n ${namespace}

Delete data#

After executing the command to destroy the cluster mentioned above, the persistent data in FE/BE of the Doris cluster will still be retained. If you no longer need this data, you can clear it using the following command:

kubectl delete pvc --selector=app.kubernetes.io/name=${cluster_name},app.kubernetes.io/managed-by=doris-operator -n ${namespace}

There will still be some Kubernetes objects shared by Doris CRs on the namespace. You can delete them using the following command:

kubectl delete secret,serviceaccount,rolebinding,role --selector=app.kubernetes.io/name=doris-cluster -n ${namespace}
