It is not trivial but possible. I did it once on RedHat7. It will probably not work with older versions of Centos/Redhat.

I explained it in this post.

Basically, you perform these steps:

• Save the container as an image, using docker commit
• Save the new image as a tar file on disk, using docker save
• Reconfigure the default space per container, as explained in this post
• In the previous step will loose all local images and containers, but you have saved your image as a tar file on disk.
• Load the image you previousley saved, using docker load
• Run a new container from the just loaded image, using docker run
