This happens when you run docker build many times in Linux/ubuntu system, then your disk/storage has no other space for your building.

• Check storage usage. You can run:
  df -h
  to see the storage/inodes used info. You will see something like:

  Filesystem      Size  Used Avail Use% Mounted on
   
  
  udev            3.9G     0  3.9G   0% /dev
  tmpfs           799M   33M  766M   5% /run
  /dev/xvda1      7.7G  4.1G  3.7G  53% /
  tmpfs           3.9G     0  3.9G   0% /dev/shm
  tmpfs           5.0M     0  5.0M   0% /run/lock
  tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
  tmpfs           799M     0  799M   0% /run/user/1000
  

• Remove docker unused files.
  
  Through cmd:
  cd /
du -chs *

  step by step, you can find out the most space used folder.
  And finally you find out /var/lib/docker folder occupies the most space.
  For me, this is my occasion. ;)
  Then I run cmd: rm * -rf in this folder. Don’t need worry.
• PS: AUFS/Laysers/Images…. if you wanna know what these folders/words are. Check the docker.io official site please.
