Deleting an OUDSM Deployment

14 Deleting an OUDSM Deployment

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

Run the following command to find the deployment release name:

helm --namespace <namespace> list

For example:

helm --namespace oudsmns list

The output will look similar to the following:

NAME    NAMESPACE       REVISION        UPDATED    STATUS          CHART           APP VERSION
oudsm   oudsmns         2               <DATE>     deployed        oudsm-0.1       14.1.2.1.0

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

Run the following command to view the status:

kubectl --namespace oudsmns 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

persistentvolume/oudsm-pv        20Gi       RWX            Delete           Terminating   oudsmns/oud-ds-rs-pvc         manual                       24m    Filesystem

NAME                              STATUS        VOLUME         CAPACITY   ACCESS MODES   STORAGECLASS   AGE   VOLUMEMODE
persistentvolumeclaim/oudsm-pvc   Terminating   oud-ds-rs-pv   20Gi       RWX            manual         24m   Filesystem

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 oudsm-pvc -n oudsmns
kubectl delete pv oudsm-pv -n oudsmns

Delete the persistent volume contents:

cd <persistent_volume>/oudsm_user_projects
rm -rf *

For example:

cd /nfs_volumes/oudsmpv/oudsm_user_projects
rm -rf *

Delete the ingress controller:
```
helm delete lbr-nginx -n <namespace>
```
For example:
```
helm delete lbr-nginx -n mynginxns
```
