Usage of /usr/bin/volume-data-source-validator:
  -add_dir_header
    	If true, adds the file directory to the header of the log messages
  -alsologtostderr
    	log to standard error as well as files (no effect when -logtostderr=true)
  -alsologtostderrthreshold value
    	logs at or above this threshold go to stderr when -alsologtostderr=true (no effect when -logtostderr=true)
  -http-endpoint :8080
    	The TCP network address where the HTTP server for diagnostics, including metrics and leader election health check, will listen (example: :8080). The default is empty string, which means the server is disabled.
  -kubeconfig string
    	Absolute path to the kubeconfig file. Required only when running out of cluster.
  -leader-election
    	Enables leader election.
  -leader-election-lease-duration duration
    	Duration, in seconds, that non-leader candidates will wait to force acquire leadership. Defaults to 15 seconds. (default 15s)
  -leader-election-namespace string
    	The namespace where the leader election resource exists. Defaults to the pod namespace if not set.
  -leader-election-renew-deadline duration
    	Duration, in seconds, that the acting leader will retry refreshing leadership before giving up. Defaults to 10 seconds. (default 10s)
  -leader-election-retry-period duration
    	Duration, in seconds, the LeaderElector clients should wait between tries of actions. Defaults to 5 seconds. (default 5s)
  -legacy_stderr_threshold_behavior
    	If true, stderrthreshold is ignored when logtostderr=true (legacy behavior). If false, stderrthreshold is honored even when logtostderr=true (default true)
  -log_backtrace_at value
    	when logging hits line file:N, emit a stack trace
  -log_dir string
    	If non-empty, write log files in this directory (no effect when -logtostderr=true)
  -log_file string
    	If non-empty, use this log file (no effect when -logtostderr=true)
  -log_file_max_size uint
    	Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
  -logtostderr
    	log to standard error instead of files (default true)
  -metrics-path /metrics
    	The HTTP path where prometheus metrics will be exposed. Default is /metrics. (default "/metrics")
  -one_output
    	If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
  -skip_headers
    	If true, avoid header prefixes in the log messages
  -skip_log_headers
    	If true, avoid headers when opening log files (no effect when -logtostderr=true)
  -stderrthreshold value
    	logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=true unless -legacy_stderr_threshold_behavior=false) (default 2)
  -v value
    	number for the log level verbosity
  -version
    	Show version.
  -vmodule value
    	comma-separated list of pattern=N settings for file-filtered logging
  -worker-threads int
    	Number of worker threads. (default 10)
