This package contains a DNS provider module for Caddy. It can be used to manage DNS records for Duck DNS.

dns.providers.duckdns

To use this module for the ACME DNS challenge, configure the ACME issuer in your Caddy JSON like so:

{
	"module": "acme",
	"challenges": {
		"dns": {
			"provider": {
				"name": "duckdns",
				"api_token": "YOUR_DUCKDNS_API_TOKEN"
			}
		}
	}
}

or with the Caddyfile:

tls {
	dns cloudflare {env.DUCKDNS_API_TOKEN}
}

You can replace {env.DUCKDNS_API_TOKEN} with the actual auth token if you prefer to put it directly in your config instead of an environment variable.

See the associated README in the libdns package for important information about credentials. Your token can be found at the top of the page when logged in at https://www.duckdns.org.
