I’ve been running Plex on a Pi 3 and now Pi 4 along with multiple other containers with no real problems. I don’t transcode obviously but have no issues with performance.
I also installed Jellyfin last week to run side by side but ended up uninstalling as even when idle the memory usage went through the roof.
Actually, the OS runs from SD and for mass storage I have a single USB drive. The container’s data is stored on the USB drive along with the docker-compose.yml file. So if I lose the SD it’s just a case of reloading the OS, installing docker and docker-compose. Configuring the disk to mount on boot and then running docker-compose to get back up and running.
Docker data is sent via rsync to a Pi Zero should the USB drive fail. Plex/Jellyfin content I don’t care too much about as they can be “obtained” again 😉
From the first boot it’s only a few lines to get docker installed ready for running containers. Containers are awesome!
