A Certbot hook for acme-dns.

go install github.com/koesie10/acme-dns-certbot-hook@latest

This project is for use with the certbot manual plugin. It needs to be run as the --manual-auth-hook in the following manner:

certbot certonly --manual --manual-auth-hook '/etc/acme-dns/acme-dns-certbot-hook -config /etc/acme-dns/acme_dns.json' --preferred-challenges dns -d example.org

In this command, you will need to change /etc/acme-dns to the path where you have placed acme-dns-certbot-hook and your config file. You will also need to change the domain and make sure you have set up the domain using acme-dns.

A sample configuration file:

{
    "acme_dns_url": "https://auth.acme-dns.io",
    "propagation_duration": "10s",
    "domains": {
        "example.org": {
            "allowfrom": [
                "192.168.100.1/24",
                "1.2.3.4/32",
                "2002:c0a8:2a00::0/40"
            ],
            "fulldomain": "8e5700ea-a4bf-41c7-8a77-e990661dcc6a.auth.acme-dns.io",
            "password": "htB9mR9DYgcu9bX_afHF62erXaH2TS7bg9KW3F7Z",
            "subdomain": "8e5700ea-a4bf-41c7-8a77-e990661dcc6a",
            "username": "c36f50e8-4632-44f0-83fe-e070fef28a10"
        }
    }
}

The acme_dns_url and propagation_duration can be overwritten per domain by specifying them along with the other information.

The information in the domain section can be directly copied from the response of the /register endpoint of the acme-dns server. Only the username and password are strictly required.
