\fIfile\fP - enables serving zone data from an RFC 1035-style master file.

|
|
.PP
|
|
The file plugin is used for an "old-style" DNS server. It serves from a preloaded file that exists
|
|
on disk. If the zone file contains signatures (i.e., is signed using DNSSEC), correct DNSSEC answers
|
|
are returned. Only NSEC is supported! If you use this setup \fIyou\fP are responsible for re-signing the
|
|
zonefile.

\fBZONES\fP zones it should be authoritative for. If empty, the zones from the configuration block

\fB\fCtransfer\fR enables zone transfers. It may be specified multiples times. \fB\fCTo\fR or \fB\fCfrom\fR signals
|
|
the direction. \fBADDRESS\fP must be denoted in CIDR notation (e.g., 127.0.0.1/32) or just as plain
|
|
addresses. The special wildcard \fB\fC*\fR means: the entire internet (only valid for 'transfer to').
|
|
When an address is specified a notify message will be send whenever the zone is reloaded.
|
|
.IP \(bu 4
|
|
\fB\fCreload\fR interval to perform a reload of the zone if the SOA version changes. Default is one minute.
|
|
Value of \fB\fC0\fR means to not scan for changes and reload. For example, \fB\fC30s\fR checks the zonefile every 30 seconds
|
|
and reloads the zone when serial changes.
|
|
.IP \(bu 4
|
|
\fB\fCupstream\fR resolve external names found (think CNAMEs) pointing to external names. This is only
|
|
really useful when CoreDNS is configured as a proxy; for normal authoritative serving you don't
|
|
need \fIor\fP want to use this. CoreDNS will resolve CNAMEs against itself.
