修改 DaemonSet 的YAML文件（kubia-ds.yaml） apiVersion: apps/v1 kind: DaemonSet metadata: name: kubia spec: selector: matchLabels: app: kubia template: metadata: labels: app: kubia spec: tolerations: - key: node-role.kubernetes.

通过添加两个标签将 Pod 组织为两个维度（基于应用的横向维度和基于版本的纵向维度）

• 更新（--overwrite）

$ kubectl label pod kubia-manual-v2 app=kubia --overwrite
pod/kubia-manual-v2 labeled

$ kubectl get pods -L app,rel
NAME                    READY   STATUS    RESTARTS   AGE    APP     REL
