cifs mount problem on debian 10

[ruchidhore12]

Hi,

I recently followed the steps for debain 10 from: http://netshare.containx.io/docs/getting-started#installation

$ wget https://github.com/ContainX/docker-volume-netshare/releases/download/v0.35/docker-volume-netshare_0.35_amd64.deb
$ sudo dpkg -i docker-volume-netshare_0.35_amd64.deb

Modified the startup options like this for cifs:

## CIFS
DKV_NETSHARE_OPTS="cifs --netrc=/root/"

Added required credentials in /root/.netrc file:

machine IP_address/folder_name
username ****
password ****
domain ****

Launched the plugin by running this in root in:
sudo docker-volume-netshare cifs --verbose

Running docker-compose.yml using docker stack deploy:

service:
   image: image
   restart: always
   volumes:
    - "cifs-test-share:path of mount:ro"

volumes:
cifs-test-share:
  driver: cifs
  driver_opts:
   share: IP_address/folder_name

My docker container does not go up and says:
"starting container failed: error while mounting volume '': VolumeDriver.Mount: exit status 32"

And in the plugin window I get this:

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Is it not able to use the credentials from the file?
Searching for this on google (mount error(95): Operation not supported) I see version option (vers=3.02) needs to be specified. There is no documentation on how to specify it?

Hi, I spent a while last night fighting with this in Ubuntu 18.4 but it works now. In your netrc file, have you tried removing share_name from the machine specification? I think it only matches on the host.
