  -deny-label-ns value
    	Comma separated list of denied label namespaces
  -enable-leader-election

  -extra-label-ns value
    	Comma separated list of allowed extra label namespaces
  -feature-gates value
    	A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:
    	DisableAutoPrefix=true|false (ALPHA - default=false)
    	NodeFeatureGroupAPI=true|false (ALPHA - default=false)
  -informer-page-size int
    	The list size to use when listing NodeFeature objects to sync informer cache. (default 200)
  -instance string
    	Instance name. Used to separate annotation namespaces for multiple parallel deployments.
  -kubeconfig string
    	Kubeconfig to use
  -label-whitelist value
    	Regular expression to filter label names to publish to the Kubernetes API server. NB: the label namespace is omitted i.e. the filter is only applied to the name part after '/'.
  -log_backtrace_at value
    	when logging hits line file:N, emit a stack trace
  -log_dir value
    	If non-empty, write log files in this directory (no effect when -logtostderr=true)
  -log_file value
    	If non-empty, use this log file (no effect when -logtostderr=true)
  -log_file_max_size value
    	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)
  -nfd-api-parallelism int
    	Defines the maximum number of goroutines responsible of updating nodes. Can be used for the throttling mechanism. (default 10)
  -no-publish
    	Do not publish feature labels
  -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) (default false)
  -options string
    	Specify config options from command line. Config options are specified in the same format as in the config file (i.e. json or yaml). These options
  -port int
    	Port which metrics and healthz endpoints are served on (default 8080)
  -prune
    	Prune all NFD related attributes from all nodes of the cluster and exit.
  -resync-period value
    	Specify the NFD API controller resync period. (default 1h0m0s)
  -skip_headers
    	If true, avoid header prefixes in the log messages (default false)
  -skip_log_headers
    	If true, avoid headers when opening log files (no effect when -logtostderr=true) (default false)
  -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) (default 2)
  -v value
    	number for the log level verbosity (default 0)
  -version
    	Print version and exit.
  -vmodule value
    	comma-separated list of pattern=N settings for file-filtered logging
