COREDNS-HTTPS(7) CoreDNS Plugins COREDNS-HTTPS(7)

NAME

https - configures DNS-over-HTTPS (DoH) server options.

DESCRIPTION

The https plugin allows you to configure parameters for the DNS-over-HTTPS (DoH) server to fine-tune the security posture and performance of the server.

This plugin can only be used once per HTTPS listener block.

SYNTAX

https {

max_connections POSITIVE_INTEGER }

max_connections limits the number of concurrent TCP connections to the HTTPS server. The default value is 200 if not specified. Set to 0 for unbounded.

EXAMPLES

Set custom limits for maximum connections:

https://.:443 {

tls cert.pem key.pem
https {
max_connections 100
}
whoami }

Set values to 0 for unbounded, matching CoreDNS behaviour before v1.14.0:

https://.:443 {

tls cert.pem key.pem
https {
max_connections 0
}
whoami }
