@MorganLindqvist - Why do you need to declare /data as a volume in Dockerfile ? If you want key persistence , it's enough to declare in your docker-compose / docker command /root/.ssh as a volume.

Is there a reason you need it to be another directory ?
Example:

docker run --name=rsync_client -v client_vol_to_sync:/data \
                 -v ssh-key:/root/.ssh \
                 -e CRON_TASK_1="0 1 * * * /data/pack-db.sh" \
                 -e CRON_TASK_2="0 3 * * * rsync -e 'ssh -p 2222' -aqx --numeric-ids [email protected]:/data/ /data/" \
