cloud.enough.community is installed with docker.

The /var/lib/docker directory is mounted on a 3 replica volume and should be manually backup from time to time to keep the history. If there is not enough space, it can be resized with:

$ openstack volume set --size 200 cloud-volume
$ ssh debian@cloud.enough.community
$ sudo resize2fs /dev/sdb

Note that the size in the ansible role for the os_volume tasks is only used when the volume is created and cannot be used to shrink or enlarge the volume.
