Description

Start Kubernetes controller manager

--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

The number of replica sets that are allowed to sync concurrently. Larger number = more responsive replica management, but more CPU (and network) load

Should CIDRs allocated by allocate-node-cidrs be configured on the cloud provider.
--controller-start-interval=0
Interval between starting controller managers.
--daemonset-lookup-cache-size=1024
The the size of lookup cache for daemonsets. Larger number = more responsive daemonsets, but more MEM load.

--deployment-controller-sync-period=0
Period for syncing the deployments.
--enable-dynamic-provisioning=true
Enable dynamic provisioning for environments that support it.
--enable-garbage-collector=false
Enables the generic garbage collector. MUST be synced with the corresponding flag of the kube-apiserver. WARNING: the generic garbage collector is an alpha feature.
--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.
--flex-volume-plugin-dir="/usr/libexec/kubernetes/kubelet-plugins/volume/exec/"
Full path of the directory in which the flex volume plugin should search for additional third party volume plugins.
--horizontal-pod-autoscaler-sync-period=0
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-content-type="application/vnd.kubernetes.protobuf"
Content type of requests sent to 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=0
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=0
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=0
The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled.
--master=""
The address of the Kubernetes API server (overrides any value in kubeconfig)
--min-resync-period=0
The resync period in reflectors will be random between MinResyncPeriod and 2*MinResyncPeriod
--namespace-sync-period=0
The period for syncing namespace life-cycle updates
--node-cidr-mask-size=24
Mask size for node cidr in cluster.
--node-monitor-grace-period=0
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=0
The period for syncing NodeStatus in NodeController.
--node-startup-grace-period=0
Amount of time which we allow starting Node to be unresponsive before marking it unhealty.
--node-sync-period=0
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=0
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-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.

--register-retry-count=10
The number of retries for initial node registration. Retry interval equals node-sync-period.
--replicaset-lookup-cache-size=4096
The the size of lookup cache for replicatsets. Larger number = more responsive replica management, but more MEM load.
--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=0
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-cluster-ip-range=""
CIDR Range for Services in cluster.
--service-sync-period=0
