This assumes you have installed Certbot.

• Install Certbot using PIP
• Install Certbot using snapd

You will need the certbot-dns-godaddy plugin. Check out my article on Certbot Installing DNS Plugins.

At https://developer.godaddy.com, create an API key and secret. Make sure to use your production API key and secret, not OTE.

While the key pair is being generated, in your Go Daddy DNS console, a temporary acme-challenge TXT record should be listed.

On that system that certbot was installed on, create godaddy.ini.

touch /home/john.doe/certbot/godaddy.ini

Update godaddy.ini to contain your API key and secret.

dns_godaddy_secret = 0123456789abcdef
dns_godaddy_key = abcdef0123456789

Set the godaddy.ini file to only be readable and writable by the owner of the godaddy.ini file.

chmod 0600 /home/john.doe/certbot/godaddy.ini

Issue the following command to create the wildcard and "normal" certificates using GoDaddy DNS.

certbot certonly \
  --authenticator dns-godaddy \
  --dns-godaddy-credentials ~/certbot/godaddy.ini \
  --dns-godaddy-propagation-seconds 900 \
  --keep-until-expiring --non-interactive --expand \
  --server https://acme-v02.api.letsencrypt.org/directory 
  --non-interactive --agree-tos -m john.doe@example.com \
  --domains 'example.com' \
  --domains '*.example.com'

Something like this should be returned.

Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/example.com/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/example.com/privkey.pem
This certificate expires on 2023-08-13.
These files will be updated when the certificate renews.

NEXT STEPS:
- The certificate will need to be renewed before it expires. Certbot can automatically renew the certificate in the background, but you may need to take steps to enable that functionality. See https://certbot.org/renewal-setup for instructions.
