How does one add a custom driver to Flex Volume storage plugin in Rancher 2.0 ? I am trying to add a CIFS driver using project “juliohm/kubernetes-cifs-volumedriver” . Any help to get this done will be very helpful. Thanks.

I am facing exactly the same issue.  
Did you managed to solve it?

Per this [GitHub issue](https://github.com/rancher/rke/issues/502) and per my inspection, the `/var/lib/kubelet` directory is already mounted on the host so the location of the volume plugins is be `/var/lib/kubelet/volumeplugins`.

I installed the plugin with this:

```auto
mkdir -p /var/lib/kubelet/volumeplugins/juliohm~cifs
curl -o /var/lib/kubelet/volumeplugins/juliohm~cifs/cifs https://raw.githubusercontent.com/juliohm1978/kubernetes-cifs-volumedriver/master/juliohm%7Ecifs/cifs
chmod +x /var/lib/kubelet/volumeplugins/juliohm~cifs/cifs

```

Then created the secret for the CIFS mount, and a pod with the flex volume mount and all worked.

That’s with Rancher v2.0.6.

Note: with `juliohm/kubernetes-cifs-volumedriver` I had issues with the umount not working when deleting a pod. But with [fstab/cifs](https://github.com/fstab/cifs) it works perfectly.

Hi,  
I could finally manage it with this driver: [microsoft.com/smb](http://microsoft.com/smb) ([https://github.com/Azure/kubernetes-volume-drivers/tree/master/flexvolume/smb](https://github.com/Azure/kubernetes-volume-drivers/tree/master/flexvolume/smb))

Regards

Is there any way to use rke for copying the fstab/cifs files to the master and nodes? Or does this have to be a manual step after using rke to start the cluster?
