If you reboot the system, it should be regenerated. But here's mine, from 22.12.1:
Code:
{"data-root": "/mnt/software/ix-applications/docker", "exec-opts": ["native.cgroupdriver=cgroupfs"], "iptables": false, "bridge": "none", "storage-driver": "overlay2"}
You'll likely need to change the data-root value to correspond to the pool you've chosen for your apps.
