How to issue 7 days certificate with Lets Encrypt and Certbot
It is actually pretty simple, for example with NGINX:
certbot --nginx --required-profile shortlived
As you can see, use the option --required-profile shortlived.
It can also be used with DNS-validation, the Apache plugin and so on.
Example, wildcard cert with the Bunny.Net plugin with ECC-certificates:
certbot certonly --key-type ecdsa --required-profile shortlived --authenticator dns-bunny --dns-bunny-credentials /var/lib/private/bunny.ini -d *.linux.pizza -d linux.pizza
Have fun!
