16 The Kubernetes API server validates and configures data for the api
17 objects which include pods, services, replicationcontrollers, and
18 others. The API Server services REST operations and provides the
19 frontend to the cluster's shared state through which all other
20 components interact.

35 --admission-control strings Admission is
36 divided into two phases. In the first phase, only mutating admission
37 plugins run. In the second phase, only validating admission plugins
38 run. The names in the below list may represent a validating plugin, a
39 mutating plugin, or both. The order of plugins in which they are passed
40 to this flag does not matter. Comma-delimited list of

397 --requestheader-client-ca-file string Root
398 certificate bundle to use to verify client certificates on incoming
399 requests before trusting usernames in headers specified by
400 --requestheader-username-headers. WARNING
401 generally do not depend on authorization being already done for
402 incoming requests.
403
404
405 --requestheader-extra-headers-prefix strings List of request header prefixes to inspect. X-Remote-Extra- is suggested.
406 --requestheader-group-headers strings List of request headers to inspect for groups. X-Remote-Group is suggested.
407 --requestheader-username-headers strings List of request headers to inspect for usernames. X-Remote-User is common.
408 --runtime-config mapStringString A set of key=value pairs that describe runtime configuration that may be passed to apiserver. <group>/<version> (or <version> for the core group) key can be used to turn on/off specific api versions. api/all is special key to control all api versions, be careful setting it false, unless you know what you do. api/legacy is deprecated, we will remove it in the future, so stop using it.
409 --secure-port int The port on which to serve HTTPS with authentication and authorization.It cannot be switched off with 0. (default 6443)
410 --service-account-issuer string 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.
411 --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
412 --service-account-lookup If true, validate ServiceAccount tokens exist in etcd as part of authentication. (default true)
413 --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.
414 --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.)
415 --service-cluster-ip-range ipNet A CIDR notation IP range from which to assign service cluster IPs. This must not overlap with any IP ranges assigned to nodes for pods. (default 10.0.0.0/24)
416
417
418
419 --service-node-port-range portRange A port range
420 to reserve for services with NodePort visibility. Example
421 '30000-32767'. Inclusive at both ends of the range. (default
422 30000-32767)
423
424
425 --skip-headers If true, avoid header prefixes in the log messages
426 --stderrthreshold severity logs at or above this threshold go to stderr (default 2)
427
428
429
430 --storage-backend string The storage
431 backend for persistence. Options
432 'etcd3' (default).
433
434
435 --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")
436 --target-ram-mb int Memory limit for apiserver in MB (used to configure sizes of caches, etc.)
437 --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.
438
439
440
441 --tls-cipher-suites strings
442 Comma-separated list of cipher suites for the server. If omitted, the
443 default Go cipher suites will be use. Possible values
444 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
445
446
447 --tls-min-version string Minimum TLS
448 version supported. Possible values
449 VersionTLS10, VersionTLS11, VersionTLS12
450
451
452 --tls-private-key-file string File containing the default x509 private key matching --tls-cert-file.
453
454
455
456 --tls-sni-cert-key namedCertKey A pair of
457 x509 certificate and private key file paths, optionally suffixed with a
458 list of domain patterns which are fully qualified domain names,
459 possibly with prefixed wildcard segments. If no domain patterns are
460 provided, the names of the certificate are extracted. Non-wildcard
461 matches trump over wildcard matches, explicit domain patterns trump
462 over extracted names. For multiple key/certificate pairs, use the
463 --tls-sni-cert-key multiple times. Examples
464 "example.crt,example.key" or "foo.crt,foo.key:*.foo.com,foo.com".
465 (default [])
466
467
468 --token-auth-file string If set, the file that will be used to secure the secure port of the API server via token authentication.

476 --vmodule moduleSpec
477 comma-separated list of pattern=N settings for file-filtered logging
478 --watch-cache Enable
479 watch caching in the apiserver (default true) --watch-cache-sizes
480 strings List of watch cache sizes for
481 every resource (pods, nodes, etc.), comma separated. The individual
482 override format
483 resource[.group]#size, where resource is lowercase plural (no
484 version), group is optional, and size is a number. It takes effect when
485 watch-cache is enabled. Some resources (replicationcontrollers,
486 endpoints, nodes, pods, services, apiservices.apiregistration.k8s.io)
487 have system defaults set by heuristics, others default to
488 default-watch-cache-size
