Docker Commit Failed: no space left on device

  • Issue type: Docker Commit Failed

$ docker commit -m “Comments” opensive_meninsky centos_django:1.0
Error response from daemon: Error processing tar file(exit status 1): write /var/lib/docker/devicemapper/devicemapper/data: no space left on device

  • OS Version/build: CentOS 7 3.10.0-957.el7.x86_64

  • App version : Docker CE 19.03.8

  • Steps to reproduce
    when i committed container to build new image, i took about 15mins and failed with this message.

Error response from daemon: Error processing tar file(exit status 1): write /var/lib/docker/devicemapper/devicemapper/data: no space left on device

wired thing is docker use overlay2 but looks like there is problem with devicemapper data file.
(docker devicemapper data file size increasing exponentially)
and the file is inside of another container.

here is the that i found about this issue.
How can i solve this issue?
thanks.

I’ve dig in this issue for a couple of days but i couldn’t find why.

here’s what i found.

i’m not sure this causes the problem but i found the container itself has docker binary and it use devicemapper.

so i decided not to use this image and will find other clean base image.

i’m not gonna drill down more and want to close this issue.
