I am getting this error whenever I am trying to build my image. Searched on internet and got some links but none of them solved my problem.
Error: System error: write /cgroup/docker/5dba72d862bf8171d36aa022d1929455af6589af9fb7ba6220b01842c7a7dee6/cgroup.procs: no space left on device.
This is the output of 'df -h':
