Last thing I need is Kubernetes at home

Docker lets my OS be be boring (and lets me basically never touch it) while having up to date user-facing software. No “well, this new version fixes a bug that’s annoying me, but it’s not in Debian stable… do I risk a 3rd party back port repo screwing up my system or other services, or upgrade the whole OS just to get one newer package, which comes with similar risks?”
I just use shell scripts to launch the services, one script per service. Run the script once, forget about it until I want to upgrade it. Modify the version in the script, take the container down and destroy it (easily automated as part of the scripts, but I haven’t bothered), run the script. Done, forget about it again until next time.
Almost all the commands I run on my server are basic file management, docker stuff, or zfs commands. I could switch distros entirely and hardly even notice. Truly a boring OS.
In these rare cases I usually just compile a newer deb package myself and let the package manager deal with it as usual. If there are too many dependencies to update or it's unusually complex, then it's container time indeed - but I didn't have to go there on my server so far.
Not diverging from the distro packages lets me not worry about security updates; Debian handles that for me.
