\fIauto\fR \- enables serving zone data from an RFC 1035\-style master file, which is automatically picked up from disk\.
|
|
.
|
|
.SH "DESCRIPTION"
|
|
The \fIauto\fR 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, i\.e\. using DNSSEC) correct DNSSEC answers are returned\. Only NSEC is supported! If you use this setup \fIyou\fR are responsible for re\-signing the zonefile\. New or changed zones are automatically picked up from disk\.

\fBdirectory\fR loads zones from the specified \fBDIR\fR\. If a file name matches \fBREGEXP\fR it will be used to extract the origin\. \fBORIGIN_TEMPLATE\fR will be used as a template for the origin\. Strings like \fB{<number>}\fR are replaced with the respective matches in the file name, e\.g\. \fB{1}\fR is the first match, \fB{2}\fR is the second\. The default is: \fBdb\e\.(\.*) {1}\fR i\.e\. from a file with the name \fBdb\.example\.com\fR, the extracted origin will be \fBexample\.com\fR\. \fBTIMEOUT\fR specifies how often CoreDNS should scan the directory; the default is every 60 seconds\. This value is in seconds\. The minimum value is 1 second\.

\fBreload\fR interval to perform reload of zone if SOA version changes\. Default is one minute\. Value of \fB0\fR means to not scan for changes and reload\. eg\. \fB30s\fR checks zonefile every 30 seconds and reloads zone when serial changes\.

\fBupstream\fR defines upstream resolvers to be used resolve external names found (think CNAMEs) pointing to external names\. \fBADDRESS\fR can be an IP address, an IP:port or a string pointing to a file that is structured as /etc/resolv\.conf\. If no \fBADDRESS\fR is given, CoreDNS will resolve CNAMEs against itself\.

All directives from the \fIfile\fR plugin are supported\. Note that \fIauto\fR will load all zones found, even though the directive might only receive queries for a specific zone\. I\.e:
