First create the directory on the share e.g. dock_vol
mkdir /mnt/backup/dock_vol
Create volume with cifs driver
docker volume create \ --driver local \ --opt type=cifs \ --opt device=//uxxxxxx.your-storagebox.de/backup/dock_vol \ --opt o=addr=uxxxxxx.your-storagebox.de,iocharset=utf8,rw,username=uxxxxxx,password=xxxxxxxxxx,file_mode=0660,dir_mode=0660 \ --name cifs_volume
This is enough, you don't need to mount the share on host as well.
If the app running in container is running and trying to write as a different user than root, you will need to adjust the permissions in above command that creates volumes to …file_mode=0777,dir_mode=0777…, as per this example.
Ansible playbook task example:
- hosts: "myhost"
pre_tasks:
- name: Create docker volume on shared storagebox
docker_volume:
name: cifs_volume
driver_options:
type: cifs
device: "device=//uxxxxxx.your-storagebox.de/backup/dock_vol"
o: "addr=uxxxxxx.your-storagebox.de,iocharset=utf8,rw,username=uxxxxxx,password=xxxxxxxxxx,file_mode=0660,dir_mode=0660"
tags: volume
Test example
docker run -d \ --name=nginxtest \ -v cifs_volume:/usr/share/nginx/html \ nginx:latest
