Uninstalling Snapshot Manager from Kubernetes cluster

When you uninstall Snapshot Manager from Kubernetes cluster, the Snapshot Manager related services are deleted from the cluster.

Delete cpServer related parameters from environment.yaml file and apply it.
```
ENVIRONMENT_NAMESPACE="netbackup-environment"
# Make sure the flexsnap-operator pod is running and ready. 
# Comment out / remove cpServer part from environment.yaml then apply it.
```
Following commands can be used to remove and disable the Snapshot Manager from NetBackup:
kubectl apply -f environment.yaml -n $ENVIRONMENT_NAMESPACE sleep 10s
Ensure that you get the uninstall message in flexsnap-operator operator log.
To clean-up cpServer component, delete flexsnap specific persistent volumes (PVs), persistent volume claims (PVCs) and config maps. Note that these resources contain metadata of current cpServer installation and would be deleted.
Use the following respective commands to delete these resources:
- To remove certauth-pvc, cloudpoint-pvc and mongodb-pvc: # kubectl delete pvc certauth-pvc cloudpoint-pvc mongodb-pvc -n <nb-namespace>
- To remove associated PVs of certauth-pvc, cloudpoint-pvc and mongodb-pvc: # kubectl delete pv <pv-name> -n <nb-namespace>
- To remove nbuconf and flexsnap-conf: # kubectl delete cm nbuconf flexsnap-conf -n <nb-namespace>
