 === Controlling ServiceLB Node Selection
 
 Adding the `svccontroller.k3s.cattle.io/enablelb=true` label to one or more nodes switches the ServiceLB controller into allow-list mode, where only nodes with the label are eligible to host LoadBalancer pods. Nodes that remain unlabeled will be excluded from use by ServiceLB.

 === ServiceLB 노드 선택 제어하기
 
 하나 이상의 노드에 `svccontroller.k3s.cattle.io/enablelb=true` 레이블을 추가하면 ServiceLB 컨트롤러가 허용 목록 모드로 전환되며, 해당 레이블이 있는 노드만 LoadBalancer 파드를 호스트할 수 있습니다. 레이블이 없는 노드는 ServiceLB에서 사용에서 제외됩니다.

 === 控制 ServiceLB 节点选择
 
 如果你将 `svccontroller.k3s.cattle.io/enablelb=true` 标签添加到一个或多个节点，ServiceLB 控制器会切换到 allow-list 模式，只有具有该标签的节点才有资格托管 LoadBalancer Pod。未标记的节点将被 ServiceLB 排除。
