Certbot DNS Plugin for Hetzner Cloud DNS

Certbot DNS Plugin for Hetzner Cloud DNS

This is a Certbot DNS plugin for the new Hetzner Cloud DNS, which allows you to automate the process of obtaining and renewing SSL/TLS certificates using the DNS-01 challenge method. This Plugin is not compatible with the old Hetzner DNS Console and you might want to take a look at the certbot-dns-hetzner plugin instead.

Setup

Installation

To install the Certbot DNS plugin for Hetzner Cloud DNS, you can either use pip or snap.

Installation using pip

If you installed Certbot within a virtual environment (e.g., /opt/certbot) as per official Certbot instructions you can install the plugin using the following command:

/opt/certbot/bin/pip install certbot-dns-hetzner-cloud

Installation using snap

If you installed Certbot using snap, you can install the plugin with the following command:

sudo snap install certbot-dns-hetzner-cloud

Verification

After installation, you can verify that the plugin is available by running:

certbot plugins

you should see dns-hetzner-cloud listed among the available plugins.

Storing the API Token

Create a configuration file under /etc/letsencrypt/hetzner_cloud.ini with the following content:

# Hetzner Cloud API Token
dns_hetzner_cloud_api_token = your_api_token_here

Make sure to set the correct permissions for the configuration file to protect your API token:

sudo chmod 600 /etc/letsencrypt/hetzner_cloud.ini

If you want to use a different path for the configuration file, you can specify it using the --dns-hetzner-cloud-credentials option when running Certbot.

Usage

You can use the plugin with Certbot by specifying the dns-hetzner-cloud authenticator. Here is an example command to obtain a certificate for a wildcard subdomain:

certbot certonly --agree-tos \
  --authenticator dns-hetzner-cloud \
  -d '*.example.eu'

If you want to use a different path for the configuration file, you can specify it using the
--dns-hetzner-cloud-credentials option.

certbot certonly --agree-tos \
  --authenticator dns-hetzner-cloud \
  --dns-hetzner-cloud-credentials /path/to/your/hetzner_cloud.ini \
  -d '*.example.eu'
