node/worker02 labeled[root@master01 ~]# kubectl get nodes -L region
NAME STATUS ROLES AGE VERSION REGION
master01 Ready control-plane,master 3d10h v1.21.0
worker01 Ready 3d9h v1.21.0 huanan
worker02 Ready 3d9h v1.21.0 guanzhou也可以加其它的多维度标签,用于不同的需要区分的场景如把worker01标签为华南区,A机房,测试环境,游戏业务[root@master01 ~]# kubectl label node worker01 zone=A env=test bussiness=game
node/worker01 labeled[root@master01 ~]# kubectl get node -L zone,env
