If you want to move your containers to a different location, look into configuring docker's data-root: https://stackoverflow.com/questions/24309526/how-to-change-the-docker-image-installation-directory
You copy /var/lib/docker to a new location and update /etc/docker/daemon.json
I will say: Moving data-root to an NFS mount isn't going to work well. I've tried it, and docker containers rely on filesystem features to run their overlays. On an NFS, this feature isn't present, so your services will duplicate the container's entire filesystem. This will tank your performance and is basically unusable for anything but trivial examples. Docker data-root basically needs to be a "physical" disk.
I've had no issues using NFS shares mounted as docker volumes. It's just the data-root where it'll fail.
If that's elephant garlic, then it's the wrong amount. That shit is 3x the size with 1/10 the flavor. Fuck that, I'll peel a whole head of normal garlic myself.
