Increase container volume(disk) size
With Centos 7 I did the following to increase the default size of the containers
Modify the docker config in /etc/sysconfig/docker-storage to add the line:
DOCKER_STORAGE_OPTIONS= - -storage-opt dm.basesize=20G
service docker stop
rm /var/lib/docker NOTE THIS DELETES ALL IMAGES etc. SO MAKE A BACKUP
service docker start
docker load < [each_save_in_backup.tar]
docker run -i -t [imagename] /bin/bash
In the bash prompt of the docker container “df -k” should show 20GB / file system size now.
