Chapter 8. Uninstalling Red Hat OpenShift AI Self-Managed
This section shows how to use the OpenShift command-line interface (CLI) to uninstall the Red Hat OpenShift AI Operator and any OpenShift AI components installed and managed by the Operator.
Using the CLI is the recommended way to uninstall the Operator. Depending on your version of OpenShift Container Platform, using the web console to perform the uninstallation might not prompt you to uninstall all associated components. This could leave you unclear about the final state of your cluster.
8.1. Understanding the uninstallation process
Installing Red Hat OpenShift AI created several custom resource instances on your OpenShift Container Platform cluster for various components of OpenShift AI. After installation, users likely created several additional resources while using OpenShift AI. Uninstalling OpenShift AI removes the resources that were created by the Operator, but retains the resources created by users to prevent inadvertently deleting information you might want.
What is deleted
Uninstalling OpenShift AI removes the following resources from your OpenShift Container Platform cluster:
-
DataScienceCluster
custom resource instance -
DSCInitialization
custom resource instance -
FeatureTracker
custom resource instances created during or after installation -
ServiceMesh
custom resource instance created by the Operator during or after installation -
KNativeServing
custom resource instance created by the Operator during or after installation -
redhat-ods-applications
,redhat-ods-monitoring
, andrhods-notebooks
namespaces created by the Operator -
Workloads in the
rhods-notebooks
namespace -
Subscription
,ClusterServiceVersion
, andInstallPlan
objects -
KfDef
object (version 1 Operator only)
What might remain
Uninstalling OpenShift AI retains the following resources in your OpenShift Container Platform cluster:
- Data science projects created by users
- Custom resource instances created by users
- Custom resource definitions (CRDs) created by users or by the Operator
While these resources might still remain in your OpenShift Container Platform cluster, they are not functional. After uninstalling, Red Hat recommends that you review the data science projects and custom resources in your OpenShift Container Platform cluster and delete anything no longer in use to prevent potential issues, such as pipelines that cannot run, notebooks that cannot be undeployed, or models that cannot be undeployed.

8.2. Uninstalling OpenShift AI Self-Managed by using the CLI
The following procedure shows how to use the OpenShift command-line interface (CLI) to uninstall the Red Hat OpenShift AI Operator and any OpenShift AI components installed and managed by the Operator.
Prerequisites
- You have cluster administrator privileges for your OpenShift Container Platform cluster.
- You have downloaded and installed the OpenShift command-line interface (CLI). See Installing the OpenShift CLI.
- You have backed up the persistent disks or volumes used by your persistent volume claims (PVCs).
Procedure
- Open a new terminal window.
In the OpenShift command-line interface (CLI), log in to your OpenShift Container Platform cluster as a cluster administrator, as shown in the following example:
$ oc login <openshift_cluster_url> -u system:admin
Create a
ConfigMap
object for deletion of the Red Hat OpenShift AI Operator.$ oc create configmap delete-self-managed-odh -n redhat-ods-operator
To delete the
rhods-operator
, set theaddon-managed-odh-delete
label totrue
.$ oc label configmap/delete-self-managed-odh api.openshift.com/addon-managed-odh-delete=true -n redhat-ods-operator
When all objects associated with the Operator are removed, delete the
redhat-ods-operator
project.Set an environment variable for the
redhat-ods-applications
project.$ PROJECT_NAME=redhat-ods-applications
Wait until the
redhat-ods-applications
project has been deleted.$ while oc get project $PROJECT_NAME &> /dev/null; do echo "The $PROJECT_NAME project still exists" sleep 1 done echo "The $PROJECT_NAME project no longer exists"
When the
redhat-ods-applications
project has been deleted, you see the following output.The redhat-ods-applications project no longer exists
When the
redhat-ods-applications
project has been deleted, delete theredhat-ods-operator
project.$ oc delete namespace redhat-ods-operator
Verification
Confirm that the
rhods-operator
subscription no longer exists.$ oc get subscriptions --all-namespaces | grep rhods-operator
Confirm that the following projects no longer exist.
-
redhat-ods-applications
-
redhat-ods-monitoring
-
redhat-ods-operator
rhods-notebooks
$ oc get namespaces | grep -e redhat-ods* -e rhods*
NoteThe
rhods-notebooks
project was created only if you installed the workbenches component of OpenShift AI. See Installing and managing Red Hat OpenShift AI components.
