* Remove context.Context from request.Request This removes the context from request.Request and makes all the changes in the code to make it compile again. It's all mechanical. It did unearth some weirdness in that the context was kept in handler structs which may cause havoc with concurrently handling of requests.

auto
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.
Syntax
auto [ZONES...] {
directory DIR [REGEXP ORIGIN_TEMPLATE [TIMEOUT]]
reload DURATION
no_reload
upstream
}
ZONES zones it should be authoritative for. If empty, the zones from the configuration block are used.
directoryloads 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 namedb.example.com, the extracted origin will beexample.com. TIMEOUT is deprecated and will be removed in a subsequent version.reloadwill be used, if not defined (it specifies how often CoreDNS should scan the directory to watch for file removal and addition; the default is every 60 seconds. This value is in seconds. The minimum value is 1 second.)reloadinterval to perform reloads of zones if SOA version changes and zonefiles. Default is one minute. Value of0means to not scan for changes and reload. eg.30schecks zonefile every 30 seconds and reloads zone when serial changes.no_reloaddeprecated. Sets reload to 0.upstreamdefines upstream resolvers to be used resolve external names found (think CNAMEs) pointing to external names. CoreDNS will resolve CNAMEs against itself.
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 internet, but send
notifies to 10.240.1.1
. {
auto org {
directory /etc/coredns/zones/org
transfer to *
transfer 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} 45
}
}
