+      --audit-log-maxbackup int                                 The maximum number of old audit log files to retain. Setting a value of 0 will mean there's no restriction on the number of files.
       --audit-log-maxsize int                                   The maximum size in megabytes of the audit log file before it gets rotated.
       --audit-log-mode string                                   Strategy for sending audit events. Blocking indicates sending events should block server responses. Batch causes the backend to buffer and write events asynchronously. Known modes are batch,blocking,blocking-strict. (default "blocking")
       --audit-log-path string                                   If set, all requests coming to the apiserver will be logged to this file.  '-' means standard out.

       --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 [])
