I’ve burnt to 10+ year old disks and they still work fine, mine are probably medium quailty disks but they are white printable ones and on a spindle so no idea what brand they are. DVD’s do degrade over time but I think Taiyo Yuden were supposed to be really good quality ones weren’t they?
I wrote something that can setup caddy automatically from docker labels.
It’s not well documented as I mostly wrote it for myself. https://hub.docker.com/r/mheys1/docker-dynamic-caddy https://github.com/mattheys/ddc
It basically acts like a DNS server serving up SRV records that caddy can use for dynamic configuration, I added in an on_demand_tls endpoint as well so that you don’t get spammed for non existent TLS records.
