Docker: error creating aufs mount to /var/lib/docker/aufs/mnt/15396ee0f38d161382f104e11c94b6ca0efafe10f9952e1dfba4f548009fbe59-init: invalid argument

I'm trying to build a Docker vm and continuously get this error:

error creating aufs mount to /var/lib/docker/aufs/mnt/15396ee0f38d161382f104e11c94b6ca0efafe10f9952e1dfba4f548009fbe59-init: invalid argument

I'm on Ubuntu 14 using Docker version 1.11.2, build b9f10c9. Here is the code for the Dockerimage:

#####This section has been moved into the run.sh to allow for cached builds that get the most up to date git repository. This is done by using ENTRYPOINT rather than RUN

#RUN git clone ssh://git-codecommit.us-east-1.amazonaws.com/v1/repos/Server /var/www/html
# Set file permissions
#RUN chmod -R 777 /var/www/html/storage

# Environment variables to configure php

ENV PHP_POST_MAX_SIZE 10M




EXPOSE 80 3306
CMD ["/run.sh"]

How can I fix this mounting problem?

Edit: Can running the host os on a live usb, specifically ubuntu, cause this problem?

Also I tried the suggestions from Error: "error creating aufs mount to" when building dockerfile but it didn't work.

aufs is a Docker storage driver. Docker storage drivers control how images and containers are stored on your filesystem. They’re the mechanism that lets you create images, start containers, and modify writable layers. aufs was the default storage driver before overlay2.

Now the issue may be that your Docker configuration may have different setup for the storage driver. The solution is to fix that configuration to use aufs like this:

  1. Stop Docker

    sudo systemctl stop docker

  2. Open the Docker deamon file

    sudo vi /etc/docker/daemon.json

  3. Add the following to the deamon file and save it

    {
    "storage-driver": "aufs"
}

  4. Start Docker again

    sudo systemctl start docker

Reference: Official Docker Documentation (for configuring overlay2)

Live usb is almost certainly not ext4, or one of the other supported filesystems. Most likely it's doing overlay, and I don't think you can mount an overlayfs on top of an overlayfs.

You can lookup your current filesystem for /var/lib/docker with a mount command. E.g. in my local environment (I'm symlinked, hence the extra dot in my path and files showing in homelv):

# df /var/lib/docker/.
Filesystem                               1K-blocks      Used Available Use% Mounted on
/dev/mapper/bmitch--vg-homelv 720798904 437701948 246459468  64% /home

# mount | grep /dev/mapper/bmitch
/dev/mapper/bmitch--vg-homelv on /home type ext4 (rw,relatime,data=ordered)

Note the "type ext4" in the mount output.

Docker has a list of supported backing filesystems:

  • overlay2, overlay: xfs with ftype=1, ext4
  • aufs: xfs, ext4
  • devicemapper: direct-lvm
  • btrfs: btrfs
  • zfs: zfs
  • vfs: any filesystem
