While following the tutorial for the section Fragmentation, the following docker related error rises up when trying to run the sample codes (the same error for each of them):
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.
Unable to locate output file
Didn't get the time to dive in the code base for the possible solution yet & post this up to speed up the resolution
