sudo certbot-auto renew --noninteractive --post-hook "service apache2 reload"

thanks for your post I have question: how I change this "sudo certbot certonly --noninteractive --post-hook "service nginx reload" for Certbot Auto-renew on Multiple Domains?

sudo certbot certonly --noninteractive --post-hook "service apache2 reload"

Should it be renew ?

sudo certbot certonly --noninteractive --post-hook "service apache2 reload"

Should it be renew ?

Yes renew is better, and using certbot-auto to stay up to date too.
Thanks for your reply
