RFC2136 module for Caddy

This package contains a DNS provider module for Caddy. It can be used to manage DNS records with rfc2136.

Caddy module name

dns.providers.rfc2136

Config examples

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": "rfc2136",
				"nameserver": "{env.RFC2136_NAMESERVER}",
				"tsig_algorithm": "",
				"tsig_keyname": "",
				"tsig_secret": "",
			}
		}
	}
}

or with the Caddyfile:

# globally
{
	acme_dns rfc2136 {
		nameserver {env.RFC2136_NAMESERVER}
		tsig_algorithm {env.RFC2136_TSIG_ALGORITHM}
		tsig_keyname {env.RFC2136_TSIG_KEYNAME}
		tsig_secret {env.RFC2136_TSIG_SECRET}
	}
}

# one site
tls {
	dns rfc2136 {env.RFC2136_NAMESERVER}
}

You can replace {env.RFC2136_NAMESERVER} with the actual nameserver if you prefer to put it directly in your config instead of an environment variable.

Types

type Provider

type Provider struct{ *rfc2136.Provider }

Provider lets Caddy read and manipulate DNS records hosted by this DNS provider.

func (Provider) CaddyModule

func (Provider) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (*Provider) Provision

func (p *Provider) Provision(ctx caddy.Context) error

Provision sets up the module. Implements caddy.Provisioner.

func (*Provider) UnmarshalCaddyfile

func (p *Provider) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile sets up the DNS provider from Caddyfile tokens. Syntax:

rfc2136 [<nameserver>] {
    nameserver <nameserver>
    tsig_algorithm <tsig_algorithm>
