https://access.redhat.com/documentation/en-us/red_hat_openshift_ai_self-managed/2.8/html/installing_and_uninstalling_openshift_ai_self-managed/uninstalling-openshift-ai-self-managed_uninstalling-openshift-ai-self-managed

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

Delete DCSs:

for dsc in $(oc get dsc | awk '{print $1}'); do
  oc delete dsc $dsc
done

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 the addon-managed-odh-delete label to true.

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 the redhat-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

for ns in $(oc get ns | grep -i redhat-ods | awk '{print $1}'); do
  oc delete ns $ns
done
for ns in $(oc get ns | grep -i rhods | awk '{print $1}'); do
  oc delete ns $ns
done

Check:

oc get namespaces | grep -i redhat-ods
oc get namespaces | grep -i rhods

Delete DCSs:

for dsc in $(oc get dsc | awk '{print $1}'); do
  oc delete dsc $dsc
done

Delete CRDs

This usually doesn't do the all the work... and you have to delete the finalizer manually of DSPAs!!!. Remember this should be for demos starting with RHPDS not in a real enviroment where the installation doesn't involve necesarily unistalling RHOAI.

for crd in $(oc get crd | grep opendatahub.io | awk '{print $1}'); do
  oc delete crd $crd
done

Unless it's needed and shared by other elements

Delete Knative Serving

oc delete knativeserving/knative-serving -n knative-serving

Delete Knative Eventing

oc delete knativeeventing/knative-eventing -n knative-eventing

Delete Service Mesh Control Plane objects

for smcp in $(oc get servicemeshcontrolplane -n istio-system -o name); do
  kubectl delete $smcp -n istio-system
done

And check if they're all gone.

oc get servicemeshcontrolplane -n istio-system -o name

Delete installplans of the operator if found:

for installplan in $(oc get installplans -n redhat-ods-operator -o name); do
  oc delete $installplan -n redhat-ods-operator
done
