How to use with docker-compose

[hwaterke]

I find it strange that the cifshost/share is taken from the name of the volume and not a driver option. This makes it unusable with docker-compose.

version: '2'
volumes:
  data:
    driver: cifs
    driver_opts:
      username: some_username
      password: some_password
services:
  foo:
    image: ubuntu
    command: ls -la /data
    volumes:
      - "data:/data"

which results in the following error:

INFO[0020] Mounting CIFS volume //sharetest_data on /var/lib/docker-volumes/netshare/cifs/sharetest_data 
2016/07/12 13:29:32 mount error: could not resolve address for sharetest_data: Unknown error

Could you add a driver option to override the cifshost and share?

It's already available:

    driver_opts:
      share: host:/share

Thanks for the quick reply.

Unfortunately I still have the same issue...

version: '2'
volumes:
  data:
    driver: cifs
    driver_opts:
      share: "//192.168.42.10/downloads"
      username: usr
      password: pwd
services:
  foo:
    image: ubuntu
    command: ls -la /data
    volumes:
      - "data:/data"

(same with share: "192.168.42.10:/downloads")

INFO[0003] Mounting CIFS volume //sharetest_data on /var/lib/docker-volumes/netshare/cifs/sharetest_data

Are those other options documented somewhere? I would also like to pass 'ro' in order to mount in read-only

Update: It seems there is a caching issue somewhere. When creating a new docker-compose.yml file, it seems to work but after that any docker-compose up goes back to using the name of the volume for the share. Do I need to cleanup something?

The best doc is @ http://netshare.containx.io/docs/cifs. All options to be passed by docker volume create command line are available within docker compose

This sounds like a docker-compose issue... Which version are you using?

Could you provide the logs of the docker-volume-netshare running with debug flag? Furthermore the output of docker volume ls after each attempt might be helpfull.

Hint: before you run any command on the commandline run logger -t issue49 "Doing XYZ" making it easier to correlate commands and debug output in logs

I know this is old, but I am experiencing this issue as well.

I'm not convinced the username/password options pass through to the driver. I am able to get this working with a username/password if I launch docker-volume-netshare with the username/password for the share on the command line, but not if I pass them in via those username/password options in docker-compose.

This makes configuration-driven authentication impossible and feels like a bug. :(

Hi! sorry for resurrecting old thread, but is there a way how to provide default options on startup?

i mean this is working: docker volume create -d nfs --name myvol6 -o share=10.4.1.44:/container_storage/ -o create=true docker run -it --rm --volume-driver=nfs -v myvol6:/data ubuntu:trusty

however i would like to hide the infrastructure details from the developers and somehow move -o share=10.4.1.44:/container_storage/ -o create=true to plugin defaults by adding options at plugin startup.

does that make sense? tried to add to environment file DKV_NETSHARE_OPTS="nfs -o share=10.4.1.44:/container_storage/ -o create=true" but probably spelling has to be different.a

any suggestions?
