Ensure base device size is not changed until needed

RendahLevel 2Otomatisdocker

Deskripsi

Increasing the base device size (dm.basesize) can affect all images and containers and should only be done when needed. Compliant when no dm.basesize storage option is set on the dockerd command line or in /etc/docker/daemon.json.
