Users don't want 👽 resources in clusters, and we should also be able to tell if were part of a broader installation. Note: - Operator created resources were handled in https://github.com/kubevirt/controller-lifecycle-operator-sdk/pull/18 as these labels will be common to all resources deployed by the HCO. - Now that the controller is guaranteed to have the labels, we can set env vars that reference the label values (fieldRef) to spare calling GET on the CR in the controllers. (thanks mhenriks). Signed-off-by: Alex Kalenyuk <akalenyu@redhat.com>
