After the upgrade to version 5:18.09.0~3-0~debian-stretch all images and configured containers are gone. /etc/docker/daemon.json was not touched.
{
"data-root": "/export/docker-data",
"storage-driver": "overlay2",
"bip": "10.20.0.1/16",
"userns-remap": "default"
}
How can this happen? /export/docker-data still contains GBytes of files. ???
Every helpful comment is highly appreciated.
