Hello @hpbieker,

What was your intended use of the VFS plugin? For the most part we are using it for comprehensive end-to-end testing of the CSI plugins without a dependency on a backend storage platform. Any more info here would be great to here.

@clintkitson. I am looking for a way to utilize a cifs network file system for my Docker volumes. I know I can use the local volume driver and mount the cifs file system in each container. However, this means that I will have to include the username and password in the docker-stack.yml file for each service. I was hoping to just define a volume driver that could have predefined the authentication to my cifs file store.

I guess this would be possible by using the vfs driver. Preferably, there is a cifs driver similar to the nfs driver so that the mounting of the cifs drive is handled automatically. I guess it is just a matter of generalization of the nfs driver.

What does "predefined the authentication to my cifs file store" mean?

[hpbieker]

@clintkitson Sorry for the bad wording. I mean that I do not want to specify a username, password, hostname and path each volume I create. I think this should be a part of the configuration of the volume driver.
