terName`. It should be noted that this is only used internally within Istio and is not an actual label on workload pods. If a pod contains this label, it will be overridden by Istio internally with the cluster ID specified during Istio installation. This label provides a way to select workloads by cluster when using DestinationRules. For example, a service owner could create a DestinationRule containing a subset per cluster and then use these subsets to control traffic flow to each cluster independently.</t
