Docker vs normal install

[bitmap]

For me? Docker fits into my ecosystem and provides a small bit of additional isolation of the program from the rest of the system. Additionally, if you screw something up with a container, you can start fresh super easily without much (if any) data loss. Plus, if you upgrade hardware, migration is a breeze compared to bare metal install and you never have to worry about dependencies (caveat being proper setup and drivers for hardware acceleration).

If you're ONLY running Jellyfin, you're probably fine with either route. If you want to learn docker/compose, go for it. If you're running a whole slew of services, docker is the way to go, compose specifically.
