Certbot

#Certbot

In ubuntu use certbot to generate certificates:

to use dns authentication with ionos use following option:

sudo certbot certonly \
--authenticator dns-ionos \
--dns-ionos-credentials /etc/letsencrypt/ionos.ini \
-d "thepace.uk" \
-d "*.thepace.uk"

Have the ionos.ini file contain your api secret and login info:

dns_ionos_prefix = <ionos prefix>
dns_ionos_secret = <ionos secret>
dns_ionos_endpoint = https://api.hosting.ionos.com
