Since the beginning of this year, Let’s Encrypt rolled out a new shortlived profile for certificates that make them valid for only 160 hours. The intention, as they say, is to encourage automation and reduce the window of certificate compromise (because revocation is somewhat a flakey thing).
Yet, I haven’t seen a lot of news about it since then. Hence the question: is this shorter cert thingy something you considered and deployed for your homelab?
As for me I’ve set up lego-acme with profile: "shortlived" on my rig. Lego runs on a bihourly cronjob, but only renews when a cert has >=3 days to expiry. It’s been pretty much a set-and-forget experience, although some more monitoring would be nice.
My last job had an Onlineshop, 4years in a row the colleague dealing with ssl wad on vacation when the cert ran out.
ACME is automated. Since it is all automated they are shorting the life. If your not automated have fun or purchase a longer one.
Your colleague sucked at automation. Normally, I’d say no one should be bothered on vacation, but in this case you should have called him on his vacation, since he didn’t value anyone else’s time either.
The manager sucked. There’s a lot of solutions to this issue but cross training and proper backup preparation are the most ideal ones.
