Delete a cluster

This topic describes how to delete an OceanBase cluster by using ob-operator.

Procedure

Take the ob-test cluster in the obcluster namespace as an example.

1. Run the following command to query the custom resources of all OceanBase clusters:

   kubectl get obcluster -A
   

   Here is an example of typical output:

   NAMESPACE   NAME      AGE
   obcluster   ob-test   148m
   

2. Run the following command to delete a specific OceanBase cluster:

   kubectl delete obcluster ob-test -n obcluster
   

3. Check whether the cluster and related resources are deleted.

   After you delete a cluster, you can run the following commands to check whether the related resources are deleted.

   • Check whether the pods are deleted:

     kubectl get pods -n obcluster
     

   • Check whether the tenants are deleted:

     kubectl get tenants -n obcluster
     

   • Check whether the backup files are deleted:

     kubectl get tenantbackups -n obcluster
