Since several days now, i received notification of expiration from letsencrypt to warn me around 10 subdomains certificates are going to expire.
Im pretty happy to be warned, but the main issue, is that i have no clue i used those subdomain at first.
To be pretty clear i use a wildcard dns entry on my main domain with a traefik container managing all the administrative work related to certificates. I have correct certificates working more www/git/traefik/jenkins subdomains used by others containers routed by traefik
but i dont remember at all :
More over i migrated my services on a fresh kubernetes cluster on a new server and wiped my old server, so im pretty helpless to check on my side anything about those certificates.
Is it possible to grab more information with certbot or online interface about those ?
