i'm gonna admit it, i have never used docker in my life. when i wanted a container for the sake of isolation i used LXC or since 2023 my ever growning nixos module abstracting all of systemd's isolation and resource control features

every time that approach doesn't suffice i just add a new conditional or other piece of logic to my container module, and as long as systemd lives so will my infrastructure

this started when i was 18 and bored, read all of systemd.exec(5) and configured all options for every use case that i might ever have

i did the same with the linux kernel config, i just got bored and needed something to do, so i hyperfocused on setting any and all kernel config options my linux-libre derivative has to offer for three days in a row and that was it. since then i just configure the new ones with every release that interests me once it gets pushed via RSS

i'm not sure if there is a use case for docker, i have yet to find one except pleasing future employers
