Contabo DNS Authenticator plugin for Certbot

Certbot Contabo authenticator plugin

This is a Certbot plugin to automate DNS-01 challenges for domains whose DNS is managed by Contabo. It works by interacting with the Contabo web interface through web scraping, as Contabo does not currently offer an official API for DNS management.

Important

• Web Scraping: This plugin relies on web scraping Contabo's website. If Contabo changes its website structure, this plugin may break until it's updated. The plugin is designed based on their current interface, which has been relatively stable for years.
• NO 2FA SUPPORT: This plugin does not support Contabo accounts with Two-Factor Authentication (2FA) enabled. You must use an account without 2FA for this plugin to work. Attempting to use it with a 2FA-enabled account will result in login failure (Might be supported in the future, but currently not available).

---

Installation

You can install the plugin using pip:

pip install certbot-dns-contabo

Usage

Create a credentials file like this, for example using nano /etc/letsencrypt/contabo.ini:

dns_contabo_email = [e-mail]
dns_contabo_password = your-contabo-password

Since this file contains sensitive credentials, protect it by restricting its permissions:

sudo chmod 600  /etc/letsencrypt/contabo.ini

(Replace /etc/letsencrypt/contabo.ini if you saved it in a different location.)

To request a certificate, use Certbot with the dns-contabo authenticator.

Example for example.com and *.example.com (wildcard):

sudo certbot certonly \
  --authenticator dns-contabo \
  --dns-contabo-credentials /etc/letsencrypt/contabo.ini \
  -d example.com \
  -d "*.example.com" 

Disclaimer

I am not affiliated with Contabo in any way. This plugin can stop working at any time if Contabo changes their website, which could even lead to stuff breaking on your Contabo account.
