h>Resource Types</th><td>[Pod]</td></tr><tr><th>Description</th><td><p>This label is applied to a workload internally that identifies the Kubernetes cluster containing the workload. The cluster ID is specified during Istio installation for each cluster via <code>values.global.multiCluster.clusterName</code>. 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
