k8s 相關元件啟動時 -v引數指定的日誌級別

--v=0   Generally useful for this to ALWAYS be visible to an operator.
--v=1   A reasonable default log level if you don’t want verbosity.
--v=2   Useful steady state information about the service and important log messages that may correlate to significant changes in the system. This is the recommended default log level for most systems.
--v=3   Extended information about changes.
--v=4   Debug level verbosity.
--v=6   Display requested resources.
--v=7   Display HTTP request headers.
--v=8   Display HTTP request contents

示例：

[root@node-08 ~]# cat /usr/lib/systemd/system/kubelet.service
