Deleting an OUD Deployment

15 Deleting an OUD Deployment

The following steps can be followed to delete an Oracle Unified Directory (OUD) deployment:

Run the following command to find the deployment release name:

helm --namespace <namespace> list

For example:

helm --namespace oudns list

The output will look similar to the following:

NAME            NAMESPACE       REVISION        UPDATED   STATUS          CHART           APP VERSION
oud-ds-rs       oudns           1               <DATE>    deployed        oud-ds-rs-0.2   12.2.1.4.0

Delete the deployment using the following command:
```
helm uninstall --namespace <namespace> <release>
```
For example:
```
helm uninstall --namespace oudns oud-ds-rs
```
The output will look similar to the following:
```
release "oud-ds-rs" uninstalled
```

Run the following command to view the status:

kubectl --namespace oudns get pod,service,secret,pv,pvc,ingress -o wide

Initially the pods and persistent volume (PV) and persistent volume claim (PVC) will move to a Terminating status:

NAME              READY   STATUS        RESTARTS   AGE   IP             NODE            NOMINATED NODE   READINESS GATES

Run the command again until the pods, PV and PVC disappear.
If the PV or PVC’s don’t delete, remove them manually:
```
kubectl delete pvc oud-ds-rs-pvc -n oudns
kubectl delete pv oud-ds-rs-pv -n oudns
```
Note:
If using block storage, you will see a PV and PVC for each pod. Delete all of the PVC’s and PV’s using the above commands.
Delete the persistent volume contents:

Note:
The steps below are not relevant for block storage.
```
cd <persistent_volume>/oud_user_projects
rm -rf *
```
For example:
```
cd /nfs_volumes/oudpv/oud_user_projects
rm -rf *
```
