docker checkpoints and enabling experimental features in docker server

[jdesbonnet]

I'd like to experiment with docker checkpoints which requires that the docker server has experimental features enabled. I've followed the docker documentation and added file /etc/docker/daemon.json with contents: {"experimental": true}. I have restarted the docker service (and rebooted to be certain). Yet "docker info" still reports " Experimental: false". I've got a Terramaster F8 SSD Plus running TOS 6.0.577. The docker was installed via the TOS Web UI (Docker server version: 20.10.17). Any ideas how to enable experimental features on docker?

You need to modify the daemon.json file located in the /Volume*/@apps/DockerEngine/conf/ directory, rather than the /etc/docker/ directory.
