## cloud-controller-manager
### Synopsis
The Cloud controller manager is a daemon that embeds
the cloud specific control loops shipped with Kubernetes.
```
cloud-controller-manager [flags]
```
### Options
```
--address ip DEPRECATED: the IP address on which to listen for the --port port. See --bind-address instead. (default 0.0.0.0)
--allocate-node-cidrs Should CIDRs for Pods be allocated and set on the cloud provider.
--azure-container-registry-config string Path to the file containing Azure container registry configuration information.
--bind-address ip The IP address on which to listen for the --secure-port port. The associated interface(s) must be reachable by the rest of the cluster, and by CLI/web clients. If blank, all interfaces will be used (0.0.0.0 for all IPv4 interfaces and :: for all IPv6 interfaces). (default 0.0.0.0)
--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. (default "/var/run/kubernetes")
--cidr-allocator-type string Type of CIDR allocator to use (default "RangeAllocator")
--cloud-config string The path to the cloud provider configuration file. Empty string for no configuration file.
--cloud-provider string The provider of cloud services. Cannot be empty.
--cluster-cidr string CIDR Range for Pods in cluster. Requires --allocate-node-cidrs to be true
--cluster-name string The instance prefix for the cluster. (default "kubernetes")
--concurrent-service-syncs int32 The number of services that are allowed to sync concurrently. Larger number = more responsive service management, but more CPU (and network) load (default 1)
--configure-cloud-routes Should CIDRs allocated by allocate-node-cidrs be configured on the cloud provider. (default true)
--contention-profiling Enable lock contention profiling, if profiling is enabled.
--controller-start-interval duration Interval between starting controller managers.

-h, --help help for cloud-controller-manager
--http2-max-streams-per-connection int The limit that the server gives to clients for the maximum number of streams in an HTTP/2 connection. Zero means to use golang's default.
--kube-api-burst int32 Burst to use while talking with kubernetes apiserver. (default 30)
--kube-api-content-type string Content type of requests sent to apiserver. (default "application/vnd.kubernetes.protobuf")
--kube-api-qps float32 QPS to use while talking with kubernetes apiserver. (default 20)
--kubeconfig string Path to kubeconfig file with authorization and master location information.
--leader-elect Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability. (default true)
--leader-elect-lease-duration duration 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. (default 15s)
--leader-elect-renew-deadline duration 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. (default 10s)
--leader-elect-resource-lock endpoints The type of resource object that is used for locking during leader election. Supported options are endpoints (default) and `configmaps`. (default "endpoints")
--leader-elect-retry-period duration The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled. (default 2s)
--log-flush-frequency duration Maximum number of seconds between log flushes (default 5s)
--master string The address of the Kubernetes API server (overrides any value in kubeconfig).
--min-resync-period duration The resync period in reflectors will be random between MinResyncPeriod and 2*MinResyncPeriod. (default 12h0m0s)
--node-monitor-period duration The period for syncing NodeStatus in NodeController. (default 5s)
--node-status-update-frequency duration Specifies how often the controller updates nodes' status. (default 5m0s)
--port int DEPRECATED: the port on which to serve HTTP insecurely without authentication and authorization. If 0, don't serve HTTPS at all. See --secure-port instead. (default 10253)
--profiling Enable profiling via web interface host:port/debug/pprof/ (default true)
--route-reconciliation-period duration The period for reconciling routes created for Nodes by cloud provider. (default 10s)
--secure-port int The port on which to serve HTTPS with authentication and authorization. If 0, don't serve HTTPS at all.
--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. Values are from tls package constants (https://golang.org/pkg/crypto/tls/#pkg-constants). If omitted, the default Go cipher suites will be used
--tls-min-version string Minimum TLS version supported. Value must match version names from https://golang.org/pkg/crypto/tls/#pkg-constants.
--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. 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 [])
--use-service-account-credentials If true, use individual service account credentials for each controller.
--version version[=true] Print version information and quit
```
