--goaway-chance float To prevent HTTP/2 clients from getting stuck on a single apiserver, randomly close a connection (GOAWAY). The client's other in-flight requests won't be affected, and the client will reconnect, likely landing on a different apiserver after going through the load balancer again. This argument sets the fraction of requests that will be sent a GOAWAY. Clusters with single apiservers, or which don't use a load balancer, should NOT enable this. Min is 0 (off), Max is .02 (1/50 requests); .001 (1/1000) is a recommended starting point.
--livez-grace-period duration This option represents the maximum amount of time it should take for apiserver to complete its startup sequence and become live. From apiserver's start time to when this amount of time has elapsed, /livez will assume that unfinished post-start hooks will complete successfully and therefore return true.
--master-service-namespace string DEPRECATED: the namespace from which the Kubernetes master services should be injected into pods. (default "default")
--max-mutating-requests-inflight int The maximum number of mutating requests in flight at a given time. When the server exceeds this, it rejects requests. Zero for no limit. (default 200)
--max-requests-inflight int The maximum number of non-mutating requests in flight at a given time. When the server exceeds this, it rejects requests. Zero for no limit. (default 400)
--min-request-timeout int An optional field indicating the minimum number of seconds a handler must keep a request open before timing it out. Currently only honored by the watch request handler, which picks a randomized value above this number as the connection timeout, to spread out load. (default 1800)
--request-timeout duration An optional field indicating the duration a handler must keep a request open before timing it out. This is the default request timeout for requests but may be overridden by flags such as --min-request-timeout for specific types of requests. (default 1m0s)
--shutdown-delay-duration duration Time to delay the termination. During that time the server keeps serving requests normally and /healthz returns success, but /readyz immediately returns failure. Graceful termination starts after this delay has elapsed. This can be used to allow load balancer to stop sending traffic to this server.
--target-ram-mb int Memory limit for apiserver in MB (used to configure sizes of caches, etc.)
Etcd flags:
--default-watch-cache-size int Default watch cache size. If zero, watch cache will be disabled for resources that do not have a default watch size set. (default 100)
--delete-collection-workers int Number of workers spawned for DeleteCollection call. These are used to speed up namespace cleanup. (default 1)
--enable-garbage-collector Enables the generic garbage collector. MUST be synced with the corresponding flag of the kube-controller-manager. (default true)
--encryption-provider-config string The file containing configuration for encryption providers to be used for storing secrets in etcd
--etcd-cafile string SSL Certificate Authority file used to secure etcd communication.
--etcd-certfile string SSL certification file used to secure etcd communication.
--etcd-compaction-interval duration The interval of compaction requests. If 0, the compaction request from apiserver is disabled. (default 5m0s)
--etcd-count-metric-poll-period duration Frequency of polling etcd for number of resources per type. 0 disables the metric collection. (default 1m0s)
--etcd-keyfile string SSL key file used to secure etcd communication.
--etcd-prefix string The prefix to prepend to all resource paths in etcd. (default "/registry")
--etcd-servers strings List of etcd servers to connect with (scheme://ip:port), comma separated.
--etcd-servers-overrides strings Per-resource etcd servers overrides, comma separated. The individual override format: group/resource#servers, where servers are URLs, semicolon separated.
--storage-backend string The storage backend for persistence. Options: 'etcd3' (default).
--storage-media-type string The media type to use to store objects in storage. Some resources or storage backends may only support a specific media type and will ignore this setting. (default "application/vnd.kubernetes.protobuf")
--watch-cache Enable watch caching in the apiserver (default true)
--watch-cache-sizes strings Watch cache size settings for some resources (pods, nodes, etc.), comma separated. The individual setting format: resource[.group]#size, where resource is lowercase plural (no version), group is omitted for resources of apiVersion v1 (the legacy core API) and included for others, and size is a number. It takes effect when watch-cache is enabled. Some resources (replicationcontrollers, endpoints, nodes, pods, services, apiservices.apiregistration.k8s.io) have system defaults set by heuristics, others default to default-watch-cache-size
Secure serving flags:
--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 or an unspecified address (0.0.0.0 or ::), all interfaces will be used. (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")
--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.
--secure-port int The port on which to serve HTTPS with authentication and authorization. It cannot be switched off with 0. (default 6443)
--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 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
--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 [])
Insecure serving flags:

--oidc-username-claim string The OpenID claim to use as the user name. Note that claims other than the default ('sub') is not guaranteed to be unique and immutable. This flag is experimental, please see the authentication documentation for further details. (default "sub")
--oidc-username-prefix string If provided, all usernames will be prefixed with this value. If not provided, username claims other than 'email' are prefixed by the issuer URL to avoid clashes. To skip any prefixing, provide the value '-'.
--requestheader-allowed-names strings List of client certificate common names to allow to provide usernames in headers specified by --requestheader-username-headers. If empty, any client certificate validated by the authorities in --requestheader-client-ca-file is allowed.
--requestheader-client-ca-file string Root certificate bundle to use to verify client certificates on incoming requests before trusting usernames in headers specified by --requestheader-username-headers. WARNING: generally do not depend on authorization being already done for incoming requests.
--requestheader-extra-headers-prefix strings List of request header prefixes to inspect. X-Remote-Extra- is suggested.
--requestheader-group-headers strings List of request headers to inspect for groups. X-Remote-Group is suggested.
--requestheader-username-headers strings List of request headers to inspect for usernames. X-Remote-User is common.
--service-account-issuer {service-account-issuer}/.well-known/openid-configuration Identifier of the service account token issuer. The issuer will assert this identifier in "iss" claim of issued tokens. This value is a string or URI. If this option is not a valid URI per the OpenID Discovery 1.0 spec, the ServiceAccountIssuerDiscovery feature will remain disabled, even if the feature gate is set to true. It is highly recommended that this value comply with the OpenID spec: https://openid.net/specs/openid-connect-discovery-1_0.html. In practice, this means that service-account-issuer must be an https URL. It is also highly recommended that this URL be capable of serving OpenID discovery documents at {service-account-issuer}/.well-known/openid-configuration.
--service-account-jwks-uri string Overrides the URI for the JSON Web Key Set in the discovery doc served at /.well-known/openid-configuration. This flag is useful if the discovery docand key set are served to relying parties from a URL other than the API server's external (as auto-detected or overridden with external-hostname). Only valid if the ServiceAccountIssuerDiscovery feature gate is enabled.
--service-account-key-file stringArray File containing PEM-encoded x509 RSA or ECDSA private or public keys, used to verify ServiceAccount tokens. The specified file can contain multiple keys, and the flag can be specified multiple times with different files. If unspecified, --tls-private-key-file is used. Must be specified when --service-account-signing-key is provided
--service-account-lookup If true, validate ServiceAccount tokens exist in etcd as part of authentication. (default true)
--service-account-max-token-expiration duration The maximum validity duration of a token created by the service account token issuer. If an otherwise valid TokenRequest with a validity duration larger than this value is requested, a token will be issued with a validity duration of this value.
--token-auth-file string If set, the file that will be used to secure the secure port of the API server via token authentication.

Metrics flags:
--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 <major>.<minor>, 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.
Misc flags:
--allow-privileged If true, allow privileged containers. [default=false]
--apiserver-count int The number of apiservers running in the cluster, must be a positive number. (In use when --endpoint-reconciler-type=master-count is enabled.) (default 1)
--enable-aggregator-routing Turns on aggregator routing requests to endpoints IP rather than cluster IP.
--endpoint-reconciler-type string Use an endpoint reconciler (master-count, lease, none) (default "lease")
--event-ttl duration Amount of time to retain events. (default 1h0m0s)
--kubelet-certificate-authority string Path to a cert file for the certificate authority.

--kubelet-client-key string Path to a client key file for TLS.
--kubelet-https Use https for kubelet connections. (default true)
--kubelet-preferred-address-types strings List of the preferred NodeAddressTypes to use for kubelet connections. (default [Hostname,InternalDNS,InternalIP,ExternalDNS,ExternalIP])
--kubelet-timeout duration Timeout for kubelet operations. (default 5s)
--kubernetes-service-node-port int If non-zero, the Kubernetes master service (which apiserver creates/maintains) will be of type NodePort, using this as the value of the port. If zero, the Kubernetes master service will be of type ClusterIP.
--max-connection-bytes-per-sec int If non-zero, throttle each user connection to this number of bytes/sec. Currently only applies to long-running requests.
--proxy-client-cert-file string Client certificate used to prove the identity of the aggregator or kube-apiserver when it must call out during a request. This includes proxying requests to a user api-server and calling out to webhook admission plugins. It is expected that this cert includes a signature from the CA in the --requestheader-client-ca-file flag. That CA is published in the 'extension-apiserver-authentication' configmap in the kube-system namespace. Components receiving calls from kube-aggregator should use that CA to perform their half of the mutual TLS verification.
--proxy-client-key-file string Private key for the client certificate used to prove the identity of the aggregator or kube-apiserver when it must call out during a request. This includes proxying requests to a user api-server and calling out to webhook admission plugins.
--service-account-signing-key-file string Path to the file that contains the current private key of the service account token issuer. The issuer will sign issued ID tokens with this private key. (Requires the 'TokenRequest' feature gate.)
