Docker image installation directory on CentOS 7


Forgive me for my bad english. I want to change the image instalaltion directory. I have found a lot of tuto over the net about that, but all are mentionning to edit the /etc/sysconfig/docker to add options -g.

On my server, I do not have this file. I have created with the other_args="-g /…", but it’s not working. Is there another solution else to chhange the directory ?
