NAME
     auto  - enables serving zone data from an RFC 1035-style master file, which
     is automatically picked up from disk.

DESCRIPTION
     The auto 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 you are responsible for re-
     signing the zonefile. New or changed zones are automatically picked up from
     disk only when SOA's serial changes. If the zones are  not  updated  via  a
     zone transfer, the serial must be manually changed.

SYNTAX
	    auto [ZONES...] {
		directory DIR [REGEXP ORIGIN_TEMPLATE]
		reload DURATION
	    }

     ZONES  zones  it  should be authoritative for. If empty, the zones from the
     configuration block are used.

     *	 directory loads zones from the specified DIR. If a  file  name  matches
	 REGEXP  it  will be used to extract the origin. ORIGIN_TEMPLATE will be
	 used as a template for the origin. Strings like {<number>} are replaced
	 with the respective matches in the file name, e.g.  {1}  is  the  first
	 match, {2} is the second. The default is: db.(.*)  {1} i.e. from a file
	 with the name db.example.com, the extracted origin will be example.com.
	 REGEXP must not be longer than 10000 characters.

     *	 reload  interval to perform reloads of zones if SOA version changes and
	 zonefiles. It specifies how often CoreDNS should scan the directory  to
	 watch for file removal and addition. Default is one minute.  Value of 0
	 means to not scan for changes and reload. eg. 30s checks zonefile every
	 30 seconds and reloads zone when serial changes.

     For enabling zone transfers look at the transfer plugin.

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

	    . {
		auto example.org {
		    directory /etc/coredns/zones
		}
	    }

     Will  happily  pick  up  a  zone  for  example.COM, except it will never be
     queried, because the auto directive only is authoritative for example.ORG.

EXAMPLES
     Load org domains from /etc/coredns/zones/org and allow transfers to the in-
     ternet, but send notifies to 10.240.1.1

	    org {
		auto {
		    directory /etc/coredns/zones/org
		}
		transfer {
		    to *
		    to 10.240.1.1
		}
	    }

     Load org domains from /etc/coredns/zones/org and looks for  file  names  as
     www.db.example.org, where example.org is the origin. Scan every 45 seconds.

	    org {
		auto {
		    directory /etc/coredns/zones/org www\.db\.(.*) {1}
		    reload 45s
		}
	    }

ALSO
     Use the root plugin to help you specify the location of the zone files. See
     the transfer plugin to enable outgoing zone transfers.
