I am running docker for windows on Windows 10

I would like attach a volume to a linux based container. This volume in available on our intranet and is a SMB storage.

On my host machine, I have mapped it with letter G:.

$user = “publishingstudio@xxxxxx”
$pwd = ConvertTo-SecureString “xxxxxxxxxx” -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential($user, pwd) New-SmbGlobalMapping -RemotePath \\xxxxx\publishingstudio -Credential $cred -LocalPath G:

I am able to access its content using windows explorer

Now, I have tried to shared this location with windows for docker using docker for windows setting panel/

When I click on ‘Apply & Restart’, I have a strange behaviour. A line is added but is empty.

I then try to use it using a docker run command.

docker run -v g:/:/data my_container

The container is launch but there is no data.

What is wrong?

Thanks for you help.

I would like attach a volume to a linux based container. This volume in available on our intranet and is a SMB storage.

I would try to mount it directly into the container with mount -t cifs .

It means I need to launch the container with a --priviledge option because I saw that mount command is not available in “docker run” normal mode.

Do you have an example of how to use mount with credantials? I am not so familiar with linux environment.

Thanks for you help.

type: cifs o: "username=${SMBUSER},password=${SMBPASSWORD}" device: "//192.168.1.220/Media 2/Videos"

I have a NAS with movies at the address you see above. To run the compose file enter:

$ export SMBUSER= # your smb user name here
$ export SMBPASSWORD= # and here your password
$ docker-compose up
It will just list the files in Videos and then the container exits.

You will probably have to set some more options like iocharset to get a working system. Take a look at man mount.cifs for that.
(Edit: I forgot to mention that I typed these commands in WSL2. In PowerShell you set environment variables with $Env:....)
driver_opts:
  type: cifs
  o: "username=publishingstudio@stro.fr.traceparts.com,password=xxxx"
  device: "//syno3.stro.fr.traceparts.com/publishingstudio$"
I get the following error

ERROR: Invalid interpolation format for “driver_opts” option in volume “networkShared”: “//syno3.stro.fr.traceparts.com/publishingstudio$”
Is it due to the ‘$’ character?
              
Ok I found the problem I need to unspecify $ by doubling it.
Now I get another error :

Where does /var/lib/docker/volumes/test_networkShared/_data comes from?
