I have changed the docker root directory location from /var/lib/docker to my custom location. All the files are copied from the docker root directory.

If I created a new container it was working fine

How can i up the previously running container
Previous running container and docker images not showing. Kindly help me on this

Al West:
Make sure permissions are set correctly. It is recommend to copy with rsync. Also check the Docker service logs:

journalctl -xu docker
#3

saravanan veera:
Yes, for the coping the file used rsync

#4

Al West:
please paste the command line you ran for rsync

#5

saravanan veera:
rsync -avxp /var/lib/docker/ /docker

#6

Al West:
Is there anything showing in the logs?

Al West:
is that all that is in the logs?

#9

Al West:
I take it you stopped all your containers before copying and then tried to restart them.

#10

Al West:
And you are sure docker images is not showing your old images?

#11

saravanan veera:
Yes, i stopped the container before the rsync

#12

Al West:
What is the contents of /etc/docker/daemon.json

#13

saravanan veera:
{
“data-root”: “/nodejs/docker”,
“log-driver”: “json-file”,
“log-opts”: {
“max-size”: “50m”,
“max-file”: “5”,
“labels”: “com.docker.compose.service,com.docker.compose.project,com.docker.compose.oneoff”
}
}

#14

Al West:
Your rsync command does not match your data-root

#15

saravanan veera:
The Rsync command used exactly which i have mentioned in the demon config file path

Previously I was given a sample path

#16

Al West:
Did you restart the docker service?

#17

saravanan veera:
Fixed the issue, Thanks for your assistance

#18

Al West:
What was the fix?

#19

Al West:
Will be helpful for others.

From our case after the file syncs someone update the docker package that’s the issue
