linux - What is the '.save_docker/' folder? Can I delete it? -


after using docker, found disk space had been eat lot. searched google resolve problem, found post said because of aufs & devicemapper.

now found folder named .save_docker in /home. in folder, there folder names aufs, aufs folder 16 g.

i want know folder , can delete it?.

save_docker doesn't seem used in docker or boot2docker or compose or machine.

but before trying remove it, check if have:

  • stopped containers remove

    docker rm -v $(docker ps -a -q -f status=exited)

  • dangling images

    docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

for that, see hardysimpson/docker-cleanup bash script.
or dcl bash script.

then check if still have disk space issue, , if /home/.save_docker modified in way.
