sudo podman ps # get container idsudo podman stopsudo podman rm #sudo podman images # get the image idsudo podman rmi -f#sudo podman run -d --cgroup-manager=systemd --volume /opt/jellyfin/config:/config --volume /opt/jellyfin/cache:/cache --volume /storage/videos/:/media --net=host --restart=unless-stopped --device /dev/dri/renderD128:/dev/dri/renderD128 --device /dev/dri/card0:/dev/dri/card0 jellyfin/jellyfin:unstable
