Maybe you find it fun. I don’t, I prefer building software not running and setting up servers.
It’s also nontrivial once you go past some level of complexity and volume. I have made my career at building software and part of that requires understanding the limitations and specifics of the underlying hardware but at the end of the day I simply want to provision and run a container, I don’t want to think about the security and networking setup it’s not worth my time.
