Seeking advice. I have many services that require cert renewal for HTTPS. My usual workflow for nginx is:
1) set up a cron job to call certbot monthly (strictly more often than needed for a 90 day cert but I'm lazy)
2) 91 days later, re-cert fails, realize that there was a bug in my script, fix it
3) 91 days later, re-cert fails, realize there was a bug in my script, fix it
4) at this point it probably now works forever
Is there a good way to test things properly so I skip steps 2 and 3??
