cloud-controller-manager [flags]
Options
| --address ip Default: 0.0.0.0 | |
| DEPRECATED: the IP address on which to listen for the --port port (set to 0.0.0.0 for all IPv4 interfaces and :: for all IPv6 interfaces). See --bind-address instead. | |

| --cert-dir string Default: "/var/run/kubernetes" | |
| 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 Default: "RangeAllocator" | |
| Type of CIDR allocator to use | |
| --cloud-config string | |

| -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 Default: 30 | |
| Burst to use while talking with kubernetes apiserver. | |
| --kube-api-content-type string Default: "application/vnd.kubernetes.protobuf" | |
| Content type of requests sent to apiserver. | |
| --kube-api-qps float32 Default: 20 | |

| --leader-elect Default: true | |

| --leader-elect-lease-duration duration Default: 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 duration Default: 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-resource-lock endpoints Default: "endpoints" | |
| The type of resource object that is used for locking during leader election. Supported options are endpoints (default) and `configmaps`. | |
| --leader-elect-retry-period duration Default: 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 duration Default: 5s | |
| Maximum number of seconds between log flushes | |
| --master string | |
| The address of the Kubernetes API server (overrides any value in kubeconfig). | |

| Specifies how often the controller updates nodes' status. | |
| --port int Default: 10253 | |

| --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 stringSlice | |
| Comma-separated list of cipher suites for the server. If omitted, the default Go cipher suites will be use. Possible values: TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,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_RC4_128_SHA,TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,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_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 | |
