Certbot Hetzner DNS Challenge (for Docker)

If you're using certbot with Docker, you may face the problem, that the shell script provided by Hetzner does not work with the official certbot/certbot image.

Thankfully, the certbot container ships with python3 and the neccessery modules, which make it possible to write own python auth and cleanup scripts.

Usage

• Save the files somewhere on your server, i.e: /home/user/certbot/hetzner
• Edit the hetzner-auth-token file and paste your DNS auth token there
• Run docker command
• (Optional) configure crontab to run the script automatically

docker run --rm --name certbot -v /home/user/certbot/hetzner:/hetzner certbot/certbot certonly --manual --preferred-challenges=dns --manual-auth-hook "python /hetzner/certbot-hetzner-auth.py" --manual-cleanup-hook "python /hetzner/certbot-hetzner-cleanup.py" -d '<domain.tld>' -d '*.<domain.tld>'
