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!
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.
