NAME¶
kube-controller-manager - Enforces kubernetes services.
SYNOPSIS¶
kube-controller-manager [OPTIONS]
DESCRIPTION¶
The Kubernetes controller manager is a daemon that embeds the core control loops shipped with Kubernetes. In applications of robotics and automation, a control loop is a non-terminating loop that regulates the state of the system. In Kubernetes, a controller is a control loop that watches the shared state of the cluster through the apiserver and makes changes attempting to move the current state towards the desired state. Examples of controllers that ship with Kubernetes today are the replication controller, endpoints controller, namespace controller, and serviceaccounts controller.
kube-controller-manager [flags]
OPTIONS¶
--allocate-node-cidrs Should CIDRs for Pods be allocated and set on the cloud provider.
--allow-metric-labels stringToString The map from metric-label to value allow-list of this label. The key's format is <MetricName>,<LabelName>. The value's format is <allowed_value>,<allowed_value>...e.g. metric1,label1='v1,v2,v3', metric1,label2='v1,v2,v3' metric2,label1='v1,v2,v3'. (default [])
--allow-metric-labels-manifest string The path to the manifest file that contains the allow-list mapping. The format of the file is the same as the flag --allow-metric-labels. Note that the flag --allow-metric-labels will override the manifest file.
--attach-detach-reconcile-sync-period duration The reconciler sync wait time between volume attach detach. This duration must be larger than one second, and increasing this value from the default may allow for volumes to be mismatched with pods. (default 1m0s)
--authentication-kubeconfig string kubeconfig file pointing at the 'core' kubernetes server with enough rights to create tokenreviews.authentication.k8s.io. This is optional. If empty, all token requests are considered to be anonymous and no client CA is looked up in the cluster.
--authentication-skip-lookup If false, the authentication-kubeconfig will be used to lookup missing authentication configuration from the cluster.
--authentication-token-webhook-cache-ttl duration The duration to cache responses from the webhook token authenticator. (default 10s)
--authentication-tolerate-lookup-failure If true, failures to look up missing authentication configuration from the cluster are not considered fatal. Note that this can result in authentication that treats all requests as anonymous.

--authorization-kubeconfig string kubeconfig file pointing at the 'core' kubernetes server with enough rights to create subjectaccessreviews.authorization.k8s.io. This is optional. If empty, all requests not skipped by authorization are forbidden.

--cert-dir string The directory where the TLS certs are located. If --tls-cert-file and --tls-private-key-file are provided, this flag will be ignored.
--cidr-allocator-type string Type of CIDR allocator to use (default "RangeAllocator")
--client-ca-file string If set, any request presenting a client certificate signed by one of the authorities in the client-ca-file is authenticated with an identity corresponding to the CommonName of the client certificate.

--disable-attach-detach-reconcile-sync Disable volume attach detach reconciler sync. Disabling this may cause volumes to be mismatched with pods. Use wisely.
--disabled-metrics strings This flag provides an escape hatch for misbehaving metrics. You must provide the fully qualified metric name in order to disable it. Disclaimer disabling metrics is higher in precedence than showing hidden metrics.

--enable-leader-migration Whether to enable controller leader migration.
--endpoint-updates-batch-period duration The length of endpoint updates batching period. Processing of pod changes will be delayed by this duration to join them with potential upcoming updates and reduce the overall number of endpoints updates. Larger number = higher endpoint programming latency, but lower number of endpoints revision generated
--endpointslice-updates-batch-period duration The length of endpoint slice updates batching period. Processing of pod changes will be delayed by this duration to join them with potential upcoming updates and reduce the overall number of endpoints updates. Larger number = higher endpoint programming latency, but lower number of endpoints revision generated

--route-reconciliation-period duration The period for reconciling routes created for Nodes by cloud provider. (default 10s)
--secondary-node-eviction-rate float32 Number of nodes per second on which pods are deleted in case of node failure when a zone is unhealthy (see --unhealthy-zone-threshold for definition of healthy/unhealthy). Zone refers to entire cluster in non-multizone clusters. This value is implicitly overridden to 0 if the cluster size is smaller than --large-cluster-size-threshold. (default 0.01)
--secure-port int The port on which to serve HTTPS with authentication and authorization. If 0, don't serve HTTPS at all. (default 10257)
--service-account-private-key-file string Filename containing a PEM-encoded private RSA or ECDSA key used to sign service account tokens.
--service-cluster-ip-range string CIDR Range for Services in cluster. Requires --allocate-node-cidrs to be true
--show-hidden-metrics-for-version string The previous version for which you want to show hidden metrics. Only the previous minor version is meaningful, other values will not be allowed. The format is ., e.g. '1.16'. The purpose of this format is make sure you have the opportunity to notice if the next release hides additional metrics, rather than being surprised when they are permanently removed in the release after that.
--terminated-pod-gc-threshold int32 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. (default 12500)
--tls-cert-file string File containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to the directory specified by --cert-dir.
--tls-cipher-suites strings Comma-separated list of cipher suites for the server. If omitted, the default Go cipher suites will be used.
Preferred values: TLS_AES_128_GCM_SHA256, TLS_AES_256_GCM_SHA384, TLS_CHACHA20_POLY1305_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256.
Insecure values: TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_RSA_WITH_RC4_128_SHA.
--tls-min-version string Minimum TLS version supported. Possible values VersionTLS10, VersionTLS11, VersionTLS12, VersionTLS13
--tls-private-key-file string File containing the default x509 private key matching --tls-cert-file.
--tls-sni-cert-key namedCertKey A pair of x509 certificate and private key file paths, optionally suffixed with a list of domain patterns which are fully qualified domain names, possibly with prefixed wildcard segments. The domain patterns also allow IP addresses, but IPs should only be used if the apiserver has visibility to the IP address requested by a client. If no domain patterns are provided, the names of the certificate are extracted. Non-wildcard matches trump over wildcard matches, explicit domain patterns trump over extracted names. For multiple key/certificate pairs, use the --tls-sni-cert-key multiple times. Examples "example.crt,example.key" or "foo.crt,foo.key:*.foo.com,foo.com". (default [])
--unhealthy-zone-threshold float32 Fraction of Nodes in a zone which needs to be not Ready (minimum 3) for zone to be treated as unhealthy. (default 0.55)
--use-service-account-credentials If true, use individual service account credentials for each controller.
-v, --v Level number for the log level verbosity
--version version[=true] --version, --version=raw prints version information
and quits; --version=vX.Y.Z... sets the reported version
--vmodule pattern=N,... comma-separated list of pattern=N settings for
file-filtered logging (only works for text log format)
