      --address=0.0.0.0: The IP address to serve on (set to 0.0.0.0 for all interfaces)
      --allocate-node-cidrs[=false]: Should CIDRs for Pods be allocated and set on the cloud provider.

      --cluster-name="kubernetes": The instance prefix for the cluster
      --concurrent-deployment-syncs=5: The number of deployment objects that are allowed to sync concurrently. Larger number = more responsive deployments, but more CPU (and network) load
      --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-namespace-syncs=2: The number of namespace objects that are allowed to sync concurrently. Larger number = more responsive namespace termination, but more CPU (and network) load
      --concurrent-replicaset-syncs=5: The number of replica sets that are allowed to sync concurrently. Larger number = more responsive replica management, but more CPU (and network) load
      --concurrent-resource-quota-syncs=5: The number of resource quotas that are allowed to sync concurrently. Larger number = more responsive quota management, but more CPU (and network) load
      --concurrent_rc_syncs=5: The number of replication controllers that are allowed to sync concurrently. Larger number = more responsive replica management, but more CPU (and network) load
      --daemonset-lookup-cache-size=1024: The the size of lookup cache for daemonsets. Larger number = more responsive daemonsets, but more MEM load.
      --deleting-pods-burst=10: Number of nodes on which pods are bursty deleted in case of node failure. For more details look into RateLimiter.
      --deleting-pods-qps=0.1: Number of nodes per second on which pods are deleted in case of node failure.
      --deployment-controller-sync-period=30s: Period for syncing the deployments.
      --enable-hostpath-provisioner[=false]: Enable HostPath PV provisioning when running without a cloud provider. This allows testing and development of provisioning features.  HostPath provisioning is not supported in any way, won't work in a multi-node cluster, and should not be used for anything other than testing or development.
      --google-json-key="": The Google Cloud Platform Service Account JSON Key to use for authentication.
      --horizontal-pod-autoscaler-sync-period=30s: The period for syncing the number of pods in horizontal pod autoscaler.
      --kube-api-burst=30: Burst to use while talking with kubernetes apiserver
      --kube-api-qps=20: QPS to use while talking with kubernetes apiserver
      --kubeconfig="": Path to kubeconfig file with authorization and master location information.
      --leader-elect[=false]: Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability.
      --leader-elect-lease-duration=15s: The duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. This is effectively the maximum duration that a leader can be stopped before it is replaced by another candidate. This is only applicable if leader election is enabled.
      --leader-elect-renew-deadline=10s: The interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than or equal to the lease duration. This is only applicable if leader election is enabled.
      --leader-elect-retry-period=2s: The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled.
      --log-flush-frequency=5s: Maximum number of seconds between log flushes
      --master="": The address of the Kubernetes API server (overrides any value in kubeconfig)
      --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-monitor-period=5s: The period for syncing NodeStatus in NodeController.
      --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.

      --replication-controller-lookup-cache-size=4096: The the size of lookup cache for replication controllers. Larger number = more responsive replica management, but more MEM load.
      --resource-quota-sync-period=5m0s: 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.
