CoreDNS

coredns - pluggable DNS nameserver optimized for service discovery and flexibility.

Synopsis

coredns [-conf FILE] [-dns.port PORT} [OPTION]...

Description

CoreDNS is a DNS server that chains plugins. Each plugin handles a DNS feature, like rewriting queries, kubernetes service discovery or just exporting metrics. There are many other plugins, each described on https://coredns.io/plugins and their respective manual pages. Plugins not bundled by default in CoreDNS are listed on https://coredns.io/explugins.

When started without options CoreDNS will look for a file named Corefile in the current directory, if found, it will parse its contents and start up accordingly. If no Corefile is found it will start with the whoami plugin (coredns-whoami(7)) and start listening on port 53 (unless overridden with -dns.port).

Available options:

-conf FILE

specify Corefile to load, if not given CoreDNS will look for a Corefile in the current directory.

-dns.port PORT or -p PORT

override default port (53) to listen on.

-pidfile FILE

write PID to FILE.

-plugins

list all plugins and quit.

-quiet

don't print any version and port information on startup.

-version

show version and quit.
