Move containers / images to another drive (Rhel)

General Discussions

Hello,

My first time on docker and we are now using it for our production environnement, after creating, testing, and setuping all containers we discovered that the VM we are using has 2 partitions (SDA1 with 50 go for system and SDB1 with 200 go) so i need to move all containers/images and future ones to SDB1.

What is the safest and best way to do so ?

System : Red Hat Enterprise Linux Server release 7.4 (Maipo)
Docker version : Docker version 17.09.0-ce

Since we are in production we cannot get in trouble with the procedure :slight_smile:

Thank you

you can change the data root directory, “–data-root=”. But before that you have take backup of all images and containers. You will lose all running container.
