Running Docker Containers on LibreELEC

Mounting storage

Partition and format your storage device in the usual way. Reboot. When LibreELEC boots, it will automatically mount the volume somewhere in /var/media. Use the mount command to find it.

Once you know the mount path, create some systemd unit overrides that bind mount the automatic mount path to the path the Docker addon expects the docker storage to be.

mkdir -p /storage/.config/system.d/service.system.docker.service.d
mkdir -p /storage/.config/system.d/docker.service.d
printf '%b' "[Service]\nExecStartPre=/usr/bin/mount --rbind /var/media/sda1-ata-TS512GSSD370_C10 /storage/.kodi/userdata/addon_data/service.system.docker/docker" > /storage/.config/system.d/docker.service.d/mount-sda1.conf
