      --health-addr string                     The address the health endpoint binds to. (default ":9440")
      --insecure-skip-verify                   Skip TLS certificate verification when connecting to Rancher. Only used for development and testing purposes. Use at your own risk.
      --kubeconfig string                      Paths to a kubeconfig. Only required if out-of-cluster.
      --leader-elect                           Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager.
      --leader-elect-lease-duration duration   Interval at which non-leader candidates will wait to force acquire leadership (duration string) (default 15s)
      --leader-elect-renew-deadline duration   Duration that the leading controller manager will retry refreshing leadership before giving up (duration string) (default 10s)

      --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_dir string                         If non-empty, write log files in this directory (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)
      --manager-concurrency int                Number of concurrent reconciles to process simultaneously across all controllers (default 15)
      --metrics-bind-addr string               The address the metric endpoint binds to. (default ":8080")
      --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)
      --profiler-address string                Bind address to expose the pprof profiler (e.g. localhost:6060)
      --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 severity               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)
      --sync-period duration                   The minimum interval at which watched resources are reconciled (e.g. 15m) (default 2m0s)
  -v, --v Level                                number for the log level verbosity
      --vmodule moduleSpec                     comma-separated list of pattern=N settings for file-filtered logging
      --watch-filter string                    Label value that the controller watches to reconcile cluster-api objects. Label key is always cluster.x-k8s.io/watch-filter. If unspecified, the controller watches for all cluster-api objects.
