Uninstalling

Remove the PEM deployment from OpenShift Container Platform and clean up associated resources.

1. Uninstall the Helm chart

   To uninstall or delete the PEM deployment, run:

   helm delete my-release --purge

   Replace my-release with your actual release name.

2. Clean up pre-install resources

   Since certain Kubernetes resources are created using the pre-install hook, the Helm delete command will attempt to delete them as a post-delete activity. If the deletion fails, you must manually delete the following resources:

   • ConfigMap: <release-name>-Migrator-Setupfile
   • ConfigMap: <release-name>-Dbutils-Setupfile
   • PersistentVolumeClaim (if persistence is enabled): <release-name>-resources-pvc
   • PersistentVolumeClaim (if logs are enabled): <release-name>-logs-pvc
3. Delete remaining resources manually

   If needed, manually delete the resources using:

   oc delete configmap <release-name>-Migrator-Setupfile
   oc delete configmap <release-name>-Dbutils-Setupfile
   oc delete pvc <release-name>-resources-pvc
   oc delete pvc <release-name>-logs-pvc

4. Clean up secrets and persistent volumes

   Consider deleting the secrets and persistent volumes created as part of the prerequisites after creating their backups:

   oc delete secret <secret-name>
   oc delete pv <persistent-volume-name>
