kube-apiserver
Synopsis
The Kubernetes API server validates and configures data for the api objects which include pods, services, replicationcontrollers, and others. The API Server services REST operations and provides the frontend to the cluster’s shared state through which all other components interact.
kube-apiserver [flags]
Options
| --admission-control-config-file string | |
| File with admission control configuration. | |
| --advertise-address ip | |
| The IP address on which to advertise the apiserver to members of the cluster. This address must be reachable by the rest of the cluster. If blank, the --bind-address will be used. If --bind-address is unspecified, the host's default interface will be used. | |
| --allow-privileged | |
| If true, allow privileged containers. [default=false] | |
| --alsologtostderr | |
| log to standard error as well as files | |
| --anonymous-auth Default: true | |

| --api-audiences stringSlice | |
| Identifiers of the API. The service account token authenticator will validate that tokens used against the API are bound to at least one of these audiences. If the --service-account-issuer flag is configured and this flag is not, this field defaults to a single element list containing the issuer URL . | |
| --apiserver-count int Default: 1 | |
| The number of apiservers running in the cluster, must be a positive number. (In use when --endpoint-reconciler-type=master-count is enabled.) | |

| --tls-sni-cert-key namedCertKey Default: [] | |
| 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". | |
| --token-auth-file string | |
| If set, the file that will be used to secure the secure port of the API server via token authentication. | |
| -v, --v Level | |
| log level for V logs | |
| --version version[=true] | |
| Print version information and quit | |
| --vmodule moduleSpec | |
| comma-separated list of pattern=N settings for file-filtered logging | |
| --watch-cache Default: true | |
| Enable watch caching in the apiserver | |
| --watch-cache-sizes stringSlice | |
| List of watch cache sizes for every resource (pods, nodes, etc.), comma separated. The individual override format: resource[.group]#size, where resource is lowercase plural (no version), group is optional, 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 | |
