Volume mounts in windows does not work

I can confirm @samneirinck observation

I can also confirm @samneirinck observation. Same symptom.

The same over here. I tried to use the share drive function but I can only see empty directories in the container.

Hi Cameron

I assume you have ticked the C drive box and provided your credentials before attempting to to run the command? If I do that then the command does show the expected contents

Thanks
Rolf

Hi Rolf,

Yes, I have ticked the C drive box. It just tested again on Docker version 1.11.1 (build 5604cbe) on the work Dell PC and it fails. I tested the same version on my personal laptop and it works. Both have the latest Windows 10 update. The work PC is using Active Directory Windows Auth if that matters. Any other differences or PC specs you would like me to report back?

thanks,
Cameron

Okay, i think Active Directory is the reason…

Well, I have the same issue but not using Active Directory. So the problem is probably not only tied to Active Directory. I can also confirm the behaviour as described by @samneirinck.
For your information I’m using the following:

  • Windows 10 Pro 1511 (10586.218)
  • Docker4Win 1.11.1-beta 10 build 2446

Restarting computer or resetting D4W and again enabling shared drive didn’t solve the issue.

(Not sure if it is important, but as Active Directory is mentioned: I’m using a local Windows account, not my Microsoft account.)

Hi Cameron

thanks for the confirmation. We do have some users which are joined in a Domain and I know it works for them. A few more questions, do either your Username or password contain a space?

Thanks
Rolf

Rolf, neither my username nor password contain a space.

thanks for the quick reply…next step would be to poke around in the VM a little. If you have time, it would be great if you could run:

docker run -it --privileged --pid=host debian nsenter -t 1 -m -n mount
and
docker run -it --privileged --pid=host debian nsenter -t 1 -m -n tail -50 /var/log/messages

preferably, after you have disabled sharing, reset credentials and the re-shared the drive.

Thanks in advance
Rolf

I’m experiencing the same problems as others.

docker run -it --privileged --pid=host debian nsenter -t 1 -m -n mount

is returning

Mounting started working after I’ve changed my user password. Before the change it contained some unicode characters (russian letters). Seems that changing it to plain English fixed this problem for me.

Changing my domain password fixed it! Yay, I’m back in business.

I can get a volume mounted in the container, but none of the files in the host directory show up–it’s empty.

Suggestions?

how about from inside the container, cd to the mount point, and if you were to create a file, say

# cd to the mount point, then
touch thisIsANewFile.txt

does the file appear in the host directory.?

If not, perhaps doing a docker inspect on the container to review the mounts points.

After doing quite a few tests, I have come to the conclusion that my docker containers are writing changes into persistent storage on the hyper-v VM instead of a share with windows. Files/folders will persist between different vm sessions but in no way show up on my windows hard drive.

Try this out and see if anyone experiences the same as me:

docker run --rm -v C:/:/data alpine ls /data/
docker run --rm -v C:/:/data alpine touch /data/foo.bar
docker run --rm -v C:/:/data alpine ls /data/
    foo.bar

Also of interest (after reset to defaults and re-share C):

docker run --rm -v /home/..:/data alpine ls /data/
    C
    Mac
    bin
    c
    dev
    etc
    home
    init
    lib
    linuxrc
    media
    port
    proc
    root
    run
    sbin
    sys
    tmp
    usr
    var
docker run --rm -v /home/..:/data alpine ls /data/C
docker run --rm -v /home/..:/data alpine ls /data/c

Nope, nothing appears in the host directory. BTW, when I tried this again
today, the first couple of times it appeared to work, and the host files
were visible from within the container. As soon as I tried to copy one of
them to another directory in the container, however, I got a "host is down"
error, and it’s back to where it was (or worse, since these "host is down"
errors now seem to be popping up more often).

On Windows, you can try:

  • Create a local user named “dockeruser” (or anything else)
  • Add this user to a group with sufficient rights on the drive to be shared (for instance, administrators)
  • Use the docker “Manage shared drives” option and
    ** If you have any credentials there, reset them first and un-share the previously shared drives
    ** Re-share your drive(s) –
    ** When prompted for the credentials, use

10.0.75.1\dockeruser

  • Run the container using

docker run -it -v C:/:/data alpine sh

  • Inside the container, verify if the host files are acessible under /data using

cd /data
ls

How to debug:

  • Inside the container, use the command “mount” and verify that you have a line such as:

//10.0.75.1/C on /app type cifs (rw,relatime,vers=1.0,cache=strict,username=dockeruser,domain=10.0.75.1,uid=0,noforceuid,gid=0,noforcegid,addr=10.0.75.1,file_mode=0755,dir_mode=0755,nounix,serverino,mapposix,noperm,rsize=61440,wsize=65536,actimeo=1)

  • On the Windows host, right click on the drive being shared and double check if the user “dockeruser” has full access on the share, by using “Sharing tab/Advanced Sharing/Permissions”
  • On the Windows host, double check if the user “dockeruser” has permissions to access the files on the shared drive (for instance, login as that user, or use “runas /user:dockeruser explorer.exe” and try to browse the drive)
  • For more information, read the blog post http://docker-saigon.github.io/post/Docker-Beta/
