Looking at https://sandstorm.io/news/2014-08-19-why-not-run-docker-apps from 9 years ago, it seems you think that Docker was/is poorly suited for individual user administration. Since the Internet has started enshittifying in the last few years I've been turning to self-hosting apps, but this requires researching distro-specific instructions for each new app I install, and I got burned when Arch updated their Postgres package which broke compatibility with the old database formats until I ran a manual upgrade script which required troubleshooting several errors along the way. (In hindsight, I should've picked a fixed-release distro like Debian or something.)
Would you say that there have been user-friendly Docker/etc. wrappers for self-hosting LAN services? Someone has recommended casaOS (or the proprietary Umbrel), though I haven't tried either yet.
