Try Unraid on your home server: boots from USB and runs in memory, no raid risks but have network share span several HDDs, parity HDDs, use SSD for cache.

No kubernetes involved - just a webinterface to run containers, install dockers as "apps" on your server. And Unraid is linux, you can but dont need to tinker.

Unraid is how i started using Dockers and became happy friends with my home server again. (tm)
