    root@localhost [ /tmp ]# kubectl describe ns testns
    Name:         testns
    Labels:       my-label=test-label-2
                  vSphereClusterID=domain-c50
    Annotations:  my-ann: test-ann-2
                  vmware-system-namespace-owner-count: 2
                  vmware-system-resource-pool: resgroup-153

  3. 使用 kubectl annotate 命令更新注释。
    例如, kubectl annotate --overwrite ns testns my-ann="test-ann-3"

  4. 使用 kubectl label 命令更新标签。
    例如, kubectl label --overwrite ns testns my-label="test-label-3"
    要删除标签,请运行命令 kubectl label --overwrite ns testns my-label-
  5. 描述命名空间,查看更新。
    root@localhost [ /tmp ]# kubectl describe ns testns
    Name:         testns
    Labels:       my-label=test-label-3
                  vSphereClusterID=domain-c50
