docker:write ... no space left on device

[niuk]

I am using docker , directly on Debian host. Just run out of space

docker: write /var/lib/docker/tmp/GetImageBlob955378987: no space left on device.

What can eat my root , it is pretty fresh install

root@pve:~/docker# df -kh

You going to have to allocate more space to root which is difficult.
I would instead install docker on a VM or use LXC instead.
