Uninstalling the Chart

Note: not found error can be ignored.

Before helm uninstall

kubectl delete validatingwebhookconfigurations kubecube-validating-webhook-configuration warden-validating-webhook-configuration kubecube-monitoring-admission

To uninstall/delete the kubecube helm release in namespace kubecube-system:

Uninstall KubeCube in control plane

helm uninstall kubecube -n kubecube-system

Uninstall Warden in member cluster

helm uninstall warden -n kubecube-system

After helm uninstall

The command removes all the Kubernetes components associated with the chart and deletes the release.

Note: There are some RBAC resources that are used by the preJob that can not be deleted by the uninstall command above. You might have to clean them manually with tools like kubectl. You can clean them by commands:

kubectl delete sa/kubecube-pre-job -n kubecube-system
kubectl delete clusterRole/kubecube-pre-job 
kubectl delete clusterRoleBinding/kubecube-pre-job
kubectl delete ns kubecube-system hnc-system kubecube-monitoring
