Docker Server Re-Initialization

Overview

Docker state can be reset - for example in the case of re-initializing the external storage - by following the procedure below. This is necessary because the Docker server caches a "Base Device UUID" that does not match the signature of a re-initialized external storage.

Procedure

systemctl stop docker

If there is any content in /var/lib/docker/, it must be deleted. Files will be present if Docker has been used.

rm -rf /var/lib/docker/*

systemctl start docker
