11 kube-apiserver [OPTIONS]
12
16 The Kubernetes API server validates and configures data for the api
17 objects which include pods, services, replicationcontrollers, and oth‐
18 ers. The API Server services REST operations and provides the frontend
19 to the cluster's shared state through which all other components inter‐
20 act.

28 **--address ip The IP
29 address on which to serve the insecure --port (set to 0.0.0.0 for all
30 IPv4 interfaces and ** : for all IPv6 interfaces). (default

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

410 --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.
411 --secure-port int The port on which to serve HTTPS with authentication and authorization.It cannot be switched off with 0. (default 6443)
412 --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.
413 --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
414 --service-account-lookup If true, validate ServiceAccount tokens exist in etcd as part of authentication. (default true)
415 --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.
416 --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.)
417 --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)
418 --service-node-port-range portRange A port range
422 to reserve for services with NodePort visibility. Example
423 '30000-32767'. Inclusive at both ends of the range. (default
424 30000-32767)
425 --skip-headers If true, avoid header prefixes in the log messages
428 --skip-log-headers If true, avoid headers when opening log files
429 --stderrthreshold severity logs at or above this threshold go to stderr (default 2)
430 --storage-backend string The storage
434 backend for persistence. Options 'etcd3' (default).
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")
438 --target-ram-mb int Memory limit for apiserver in MB (used to configure sizes of caches, etc.)
439 --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.
440 --tls-cipher-suites strings Comma-sepa‐
444 rated list of cipher suites for the server. If omitted, the default Go
445 cipher suites will be use. Possible values
446 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
447 --tls-min-version string Minimum TLS
450 version supported. Possible values VersionTLS10, VersionTLS11,
451 VersionTLS12, VersionTLS13
452 --tls-private-key-file string File containing the default x509 private key matching --tls-cert-file.
455 --tls-sni-cert-key namedCertKey A pair of
459 x509 certificate and private key file paths, optionally suffixed with a
460 list of domain patterns which are fully qualified domain names, possi‐
461 bly with prefixed wildcard segments. If no domain patterns are pro‐
462 vided, the names of the certificate are extracted. Non-wildcard matches
463 trump over wildcard matches, explicit domain patterns trump over
464 extracted names. For multiple key/certificate pairs, use the
465 --tls-sni-cert-key multiple times. Examples "example.crt,exam‐
466 ple.key" or "foo.crt,foo.key:*.foo.com,foo.com". (default [])
467 --token-auth-file string If set, the file that will be used to secure the secure port of the API server via token authentication.
470 -v, --v Level number
474 for the log level verbosity
475 --version version[=true] Print
476 version information and quit
477 --vmodule moduleSpec
478 comma-separated list of pattern=N settings for file-filtered logging
479 --watch-cache Enable
480 watch caching in the apiserver (default true) --watch-cache-sizes
481 strings Watch cache size settings for
482 some resources (pods, nodes, etc.), comma separated. The individual
483 setting format resource[.group]#size, where resource is lowercase
484 plural (no version), group is omitted for resources of apiVersion v1
485 (the legacy core API) and included for others, and size is a number. It
486 takes effect when watch-cache is enabled. Some resources (replication‐
487 controllers, endpoints, nodes, pods, services, apiservices.apiregistra‐
488 tion.k8s.io) have system defaults set by heuristics, others default to
489 default-watch-cache-size
