3.6. Uninstalling OpenShift Virtualization using the CLI
You can uninstall OpenShift Virtualization by using the OpenShift Container Platform CLI.
3.6.1. Prerequisites
- You must have OpenShift Virtualization 2.4 installed.
You must delete all virtual machines, virtual machine instances, and DataVolumes.
重要Attempting to uninstall OpenShift Virtualization without deleting these objects results in failure.
3.6.2. Deleting OpenShift Virtualization
You can delete OpenShift Virtualization by using the CLI.
Prerequisites
-
Install the OpenShift CLI (
oc). -
Access to a OpenShift Virtualization cluster using an account with
cluster-adminpermissions.
When you delete the subscription of the OpenShift Virtualization operator in the OLM by using the CLI, the ClusterServiceVersion (CSV) object is not deleted from the cluster. To completely uninstall OpenShift Virtualization, you must explicitly delete the CSV.
Procedure
Delete the HyperConverged Custom Resource:
$ oc delete HyperConverged kubevirt-hyperconverged -n openshift-cnv
Delete the subscription of the OpenShift Virtualization operator in the Operator Lifecycle Manager (OLM):
$ oc delete subscription kubevirt-hyperconverged -n openshift-cnv
Set the ClusterServiceVersion (CSV) name for OpenShift Virtualization as an environment variable:
$ CSV_NAME=$(oc get csv -n openshift-cnv -o=custom-columns=:metadata.name)
Delete the CSV from the OpenShift Virtualization cluster by specifying the CSV name from the previous step:
$ oc delete csv ${CSV_NAME} -n openshift-cnvOpenShift Virtualization is uninstalled when a confirmation message indicates that the CSV was deleted successfully:
Example output
clusterserviceversion.operators.coreos.com "kubevirt-hyperconverged-operator.v2.4.9" deleted
