Today I gained a little more knowledge about Caddy, and I thought I’d share in case someone is having the same issue.
I’ve been biting my nails worrying about Caddy updating certificates. Everything I had read told me not to sweat it. That Caddy had my back and wouldn’t let any certs expire. Well, two did, today. So I set about today, after I got all my chores done, to see if I could figure out wtf.
Long story short, I had a inconsistency in the format of my Caddy file. It didn’t affect the function of the file to the extent that it would not provide the certificate in daily use, but apparently I confused Caddy enough so that it couldn’t determine when certs were expiring, and reissue the cert.
If you run the following:
caddy reload --config /etc/caddy/Caddyfile
And you get something like this:
2025/04/09 21:49:03.376 WARN Caddyfile input is not formatted; run 'caddy fmt --overwrite' to fix inconsistencies{"adapter": "caddyfile", "file": "/etc/caddy/Caddyfile", "line": 1}
It’s a warning that something is askew. Not to worry tho, you can fix it thusly:
Make a backup assuming etc/caddy/Caddyfile is where your Caddyfile is:
cp /etc/caddy/Caddyfile /etc/caddy/Caddyfile.bak
Next we’ll ask Caddy nicely to please reformat in an acceptible form:
sudo caddy fmt --overwrite /etc/caddy/Caddyfile
Trust but verify:
caddy validate --config /etc/caddy/Caddyfile
Now run:
caddy reload --config /etc/caddy/Caddyfile
You should be golden at this point.
Cheers
Do ignore me then, I assumed you might know the reference and only I mean’t it in good humour. :) (Without spoiling anything - in the unlikely event you might some day watch it - Mr Milchick is a character that uses ‘big words’. Your choice of words struck a chord.) I will say though, you’re seriously missing out. The cinematography alone is brilliant and the acting exceptional.
Naw man, it’s cool. I get references, but they kind of have to be old school stuff Richard Pryor, Blazing Saddles, Young Frankenstein, that kind of stuff. I’m just a weird old man. LOL
