Red Hat OpenShift Documentation Team

Abstract

This document details how to remove OpenShift Serverless from your cluster.

Chapter 1. Removing OpenShift Serverless overview

If you need to remove OpenShift Serverless from your cluster, you can do so by manually removing the OpenShift Serverless Operator and other OpenShift Serverless components. Before you can remove the OpenShift Serverless Operator, you must remove Knative Serving and Knative Eventing.

After uninstalling the OpenShift Serverless, you can remove the Operator and API custom resource definitions (CRDs) that remain on the cluster.

The steps for fully removing OpenShift Serverless are detailed in the following procedures:

Chapter 2. Uninstalling OpenShift Serverless Knative Eventing

Before you can remove the OpenShift Serverless Operator, you must remove Knative Eventing. To uninstall Knative Eventing, you must remove the KnativeEventing custom resource (CR) and delete the knative-eventing namespace.

2.1. Uninstalling Knative Eventing

Prerequisites

You have cluster administrator permissions on OpenShift Container Platform, or you have cluster or dedicated administrator permissions on OpenShift Dedicated.
Install the OpenShift CLI (oc).

Procedure

Delete the KnativeEventing CR:

$ oc delete knativeeventings.operator.knative.dev knative-eventing -n knative-eventing

After the command has completed and all pods have been removed from the knative-eventing namespace, delete the namespace:
```
$ oc delete namespace knative-eventing
```

Chapter 3. Uninstalling OpenShift Serverless Knative Serving

Before you can remove the OpenShift Serverless Operator, you must remove Knative Serving. To uninstall Knative Serving, you must remove the KnativeServing custom resource (CR) and delete the knative-serving namespace.

3.1. Uninstalling Knative Serving

Prerequisites

You have cluster administrator permissions on OpenShift Container Platform, or you have cluster or dedicated administrator permissions on OpenShift Dedicated.

```

Chapter 4. Removing the OpenShift Serverless Operator

After you have removed Knative Serving and Knative Eventing, you can remove the OpenShift Serverless Operator. You can do this by using the web console or the oc CLI.

Chapter 5. Deleting OpenShift Serverless custom resource definitions

After uninstalling the OpenShift Serverless, the Operator and API custom resource definitions (CRDs) remain on the cluster. You can use the following procedure to remove the remaining CRDs.
