Docker Beta containers partition size

Hi, i’m using Docker Beta on my Mac, right now. But i have still problem with total containers disk space. It is any way how to increase disk size for all my containers? Currently i have only 18GB total size, but lot of free space on my machine storage. I already tried to allocate more virtual space to Docker.qcow2 file.

root@2d0f7ac08cae:/3mw# df -h Filesystem Size Used Avail Use% Mounted on none 18G 18G 0 100% / tmpfs 2.0G 0 2.0G 0% /dev tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup osxfs 112G 93G 19G 84% /3mw /dev/vda1 18G 18G 0 100% /etc/hosts shm 64M 0 64M 0% /dev/shm
