> Several resources may be leaked after this helm chart is deleted(uninstalled):
> - admission-controller
> deployment/service/mutatingwebhook/validatingwebhook/secret. The reason is
> that admission-controller resources are deleted via preStop hook of
> yunikorn-scheduler pod, the ServiceAccount and ClusterRoleBinding resources
> are probably already deleted then.
> - yunikorn-configs ConfigMap. This one is configured as pre-install hook in
> helm chart, it won't be deleted when uninstalling.
> All resources are expected to be cleaned up after the helm chart is deleted,
> to achieve that, this issue will take the ServiceAccount and
> ClusterRoleBinding resources as pre-install hooks and create a cleanup pod to
> release ConfigMap/ClusterRoleBinding/ServiceAccount resources as prometheus
> operator did (refer to
> https://github.com/helm/charts/blob/d58247103fafd5930792bb1fd3ac240547523200/stable/prometheus-operator/templates/prometheus-operator/cleanup-crds.yaml#L33).
