--cluster-name="kubernetes": The instance prefix for the cluster
--concurrent-endpoint-syncs=5: The number of endpoint syncing operations that will be done concurrently. Larger number = faster endpoint updating, but more CPU (and network) load
--concurrent_rc_syncs=5: The number of replication controllers that are allowed to sync concurrently. Larger number = more reponsive replica management, but more CPU (and network) load
--min-resync-period=12h0m0s: The resync period in reflectors will be random between MinResyncPeriod and 2*MinResyncPeriod
--namespace-sync-period=5m0s: The period for syncing namespace life-cycle updates
--node-monitor-grace-period=40s: Amount of time which we allow running Node to be unresponsive before marking it unhealty. Must be N times more than kubelet's nodeStatusUpdateFrequency, where N means number of retries allowed for kubelet to post node status.
--node-startup-grace-period=1m0s: Amount of time which we allow starting Node to be unresponsive before marking it unhealty.
--node-sync-period=10s: The period for syncing nodes from cloudprovider. Longer periods will result in fewer calls to cloud provider, but may delay addition of new nodes to cluster.
--pod-eviction-timeout=5m0s: The grace period for deleting pods on failed nodes.
--port=10252: The port that the controller-manager's http service runs on
--profiling[=true]: Enable profiling via web interface host:port/debug/pprof/
--pv-recycler-increment-timeout-nfs=30: the increment of time added per Gi to ActiveDeadlineSeconds for an NFS scrubber pod
--pv-recycler-minimum-timeout-hostpath=60: The minimum ActiveDeadlineSeconds to use for a HostPath Recycler pod. This is for development and testing only and will not work in a multi-node cluster.
--pv-recycler-minimum-timeout-nfs=300: The minimum ActiveDeadlineSeconds to use for an NFS Recycler pod
--pv-recycler-pod-template-filepath-hostpath="": The file path to a pod definition used as a template for HostPath persistent volume recycling. This is for development and testing only and will not work in a multi-node cluster.
--pv-recycler-pod-template-filepath-nfs="": The file path to a pod definition used as a template for NFS persistent volume recycling
--pv-recycler-timeout-increment-hostpath=30: the increment of time added per Gi to ActiveDeadlineSeconds for a HostPath scrubber pod. This is for development and testing only and will not work in a multi-node cluster.
--pvclaimbinder-sync-period=10s: The period for syncing persistent volumes and persistent volume claims
--resource-quota-sync-period=10s: The period for syncing quota usage status in the system
--root-ca-file="": If set, this root certificate authority will be included in service account's token secret. This must be a valid PEM-encoded CA bundle.
--service-account-private-key-file="": Filename containing a PEM-encoded private RSA key used to sign service account tokens.
--service-sync-period=5m0s: The period for syncing services with their external load balancers
--terminated-pod-gc-threshold=12500: Number of terminated pods that can exist before the terminated pod garbage collector starts deleting terminated pods. If <= 0, the terminated pod garbage collector is disabled.
