Share and learn in the Docker community.
When listing the files of a mounted volume in the container, the files from the host directory should be listed
The mounted volume appears to be empty
Docker for Windows version: 1.10.6.958
Windows version: Microsoft Windows 10 Pro
docker run -it -v /c/my_volume:/my_mnt alpine /bin/shls /my_mnt/
Found the answer here
Only the C:\Users area of the host file system is shared with the container and thus mountable.
So running docker run -it -v /c/Users/Christian/my_volume:/my_mnt alpine /bin/sh works.
Interesting because when I type docker run --rm -ti -v /c/Users/xtof/Desktop:/desktop alpine ash I have an empty /desktop directory in the container.
OK now Iām officially confused.
I made a clean install of Windows 10 and D4W and now when I run
docker run -it -v /c/Users/Christian/my_volume:/my_mnt alpine /bin/sh
I get the same issue as before i.e. the mounted directory is empty.
@chribben with D4W, all of your c-drive is mountable in containers (weāre working on supporting other drives too).
Can you confirm that drive-sharing is enabled in settings?
I tried to reproduce your problem on my machine, but cannot. Neither with a folder (with content) in C:\code nor as a sub-folder in my userās folder. Both existing and non-existing folders work correctly (the non-existing ones are empty).
If the above doesnāt solve the problem, can you try running the DockerDebugInfo.ps1 in C:\<program files>\Docker\Docker\resources?

Enabling it makes mounting work, thanks!
I hadnāt enabled drive sharing, somehow I thought this option should be enabled only if you wanted to share other folders than C:\Users.
Hi,
in my setup, I have a local user ādemoā on my Windows host which I use for the shares
I enabled the share for D Drive in d4w beta - settings and run the following commands (which work perfectly for my boot2docker+hyper-v setup) from my project folder (contains index.html):
Commands:
docker ps -a
docker rm webserver
docker run -p 80:80 -d --name webserver -v D:\prj\docker-tallinn:/usr/share/nginx/html/ nginx:alpine
docker exec -it webserver /bin/sh
ls -l /usr/share/nginx/html/
>total 0
$(iwr docker).Content

It appears that the āRewrote mount to /D/prj/docker-tallinn:/usr/share/nginx/html/ā did not work as the contents of the mounted volume is blankā¦
The setup works in Boot2Docker with the default Docker-Machine using the hyper-v driver (not using Docker-ToolBox), but it doesnāt work in d4w beta (which uses the hv_kvp_daemon to set {ācifsmountā; ā/d;/D;username=$user,password=$pass,nopermā} key-value pair for the alpine VM) Iām unable to debug as I canāt SSH into MobyLinuxVM, itās a total black box - which is very frustratingā¦ (unable to set TLS, unable to set private registry, ā¦)
Although, 1 difference between my boot2docker setup and my MobyLinuxVM is the fact that I had to set ādomainā to my computer IP for the cifs mount to work as my laptop belongs to a domain and the demo user is local only.
I just tested that the following works
#get a privileged container with access to Docker daemon
docker run --privileged -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v /usr/bin/docker:/usr/bin/docker alpine sh
#run a container with full root access to MobyLinuxVM and no seccomp profile
docker run --net=host --ipc=host --uts=host --pid=host -it --security-opt=seccomp=unconfined --privileged --rm -v /:/host alpine /bin/sh
#switch to host FS
chroot /host
#test mount the windows host folder
mount -t cifs //10.0.75.1/D /D -o user=demo,domain=10.0.75.1,pass=demo
I tried to use ā10.0.75.1\demoā to force using the correct domain when entering the credentials for the share, but it didnāt seem to accept it, repeatedly prompting me for credentials.
I will try to update the Windows Credentials Manager directly to see if I can put the credentials there and if that fixes the issue - in which case the issue would be when D4W beta tries to validate the share credentialsā¦
Iām using Amazon AMI and same issue facing, Iām using following docker command to run container but my /base/props is not mounting where my /home/props has files
docker run -d --name my-app -m 250MB -v /home/props:/base/props -p 8888:8888 my-app
Thats right. Also, under WSL, it only works by using the ā/c/Users/ā¦ā paths. Using ā/mnt/c/Users/ā¦ā paths makes the container mounted directory to be empty:
Doesnāt work correctly with WSL:
docker run -v /mnt/c/Users/myuser/folder:/var/sites/ --rm -it --entrypoint /bin/bash my-registry:7090/apache-image:1.0.0
[/var/sites directory looks empty inside the container]
Works OK with WSL:
docker run -v /c/Users/myuser/folder:/var/sites/ --rm -it --entrypoint /bin/bash my-registry:7090/apache-image:1.0.0
[/var/sites correctly mounted]
