Remove Che from your cluster

Remove Che and all related user data from your Kubernetes cluster when you no longer need the platform or want to perform a clean reinstallation.

This page is for platform administrators who install, configure, and manage Che on Kubernetes clusters. To learn more about common roles and example tasks referenced in Che documentation, see Common user roles and tasks.

Uninstalling Che removes all Che-related user data.

Prerequisites

You have an active kubectl session with administrative permissions to the Kubernetes cluster. See Getting started with the OpenShift CLI.
You have the chectl management tool installed. See Set up the chectl command-line tool.

Procedure

Remove the Che instance:
```
$ chectl server:delete
```
The --delete-namespace option removes the Che namespace.

The --delete-all option removes the DevWorkspace Operator and the related resources.

Standard operating procedure (SOP) for removing DevWorkspace Operator manually without chectl is available in the OpenShift Container Platform official documentation.

Verification

Verify that the Che namespace has been removed:
```
kubectl get namespace eclipse-che
```
The expected output is NotFound.
