CIFS mount owner cannot be specified

[Somebody25]

Hello!

I tired to execute a docker-compose built, where I wanted to use a samba share as volume.
The user of the mount is still the remote user, even if is specify an other user with --opt uid=0 --opt gid=0
This is not the case when I mount manually.

Docker volume create:
docker volume create -d cifs --name server_url/share --opt username=username --opt password=password --opt uid=0 --opt gid=0 --opt fileMode=0777 --opt dirMode=0777

Result when launching the docker-compose app:
root@server /var/lib/docker-volumes/netshare/cifs/server_url # ls -l
drwxr-xr-x+ 7 175443 175443 0 Apr 15 17:00 share

Manual mount:
mount.cifs -o user=username,pass=password,uid=0,gid=0 //server_url/share /mnt/share

Result of manual mount:
drwxr-xr-x+ 7 root root 0 Apr 15 17:00 share

The effect is, that the docker-compose application cannot write to the share.

Thanks in advance

Regards
