Hm, these days I feel like I only have to learn systemd. Reload config? View logs? Watchdog? Namespaces? It’s all systemd. If you are running on one machine, what does Docker/k8s give you that you do not already have?
Nothing, but its pretty common to have the home server plus a desktop/laptop where you do most of the work (even for home server), that may not be linux - in which case containers are the easiest way
That feeling that you are part of a special, futuristic club.
