Fair enough, would love to read something like this :-)
Yeah, I’ve been into Linux for 20 years, sometimes a bit on/off, as an all-around-sysadmin in mainly Windows places. And learned just enough of Docker to use it instead of apt - which I’d prefer, but as you said, many newer services don’t exist in debian repos or as .deb packages, only docker or similar.
You could, but for many of us, the point of having access to our services is to have access from anywhere :-)
