hi @andyzhangx, can you please join the sig-windows slack channel where windows development is happening. i would love to discuss this feature request at our next meeting. ping me in Kubernetes slack (mmichael) for details
Huamin Chen
@andyzhangx would flex or csi work? There are already cifs flex drivers around.
Andy Zhang
@rootfs that's good question, I will try flex on Windows first, it's in my list.
Andy Zhang
@michmike I am already in sig-windows, just mute in the group. And I am in China, the meeting time is too late for me, could you just paste your discussion result here? Thanks.
I raised this feature proposal just want to know whether there is some requiremnt for a new upstream SMB plugin, or a working cifs flex driver is enough?
Andy Zhang
BTW, this month, azure released Windows Server version 1709, by this OS, azure disk & file mount is already supported on Windows starting from v1.7.2.
You could find detailed info here:

@andyzhangx we record all our meetings on youtube here https://www.youtube.com/playlist?list=PL69nYSiGNLP2OH9InCcNkWNu2bl-gmIU4
Right now, we have not discussed this at all, but we can add it for discussion after v1.9 ships.

I would like to have such a feature as well. Any progress?
Andy Zhang
There is already a cifs flexvolume plugin on Linux, and I will write a cifs CSI driver on windows
Andy Zhang
And before writing a new cifs CSI driver for windows, we need to make sure CSI driver works on windows well first, it depends on kubernetes-csi/drivers#79

Flexvolume driver for SMB here: https://github.com/Microsoft/K8s-Storage-Plugins

@andyzhangx with csi-proxy project, I think it provides a way to implement a generic CSI smb driver. Do you still have interests in working on it?

yes, it's tracking here: Azure/kubernetes-volume-drivers#48, will work out a working driver first.
Andy Zhang
the new driver functionality is actually subset of https://github.com/kubernetes-sigs/azurefile-csi-driver since it won't need dynamic provisioning, I am planning to create a new project, e.g. smb-csi-driver, put it under https://github.com/kubernetes-sigs/ finally.
The new CSI driver https://github.com/kubernetes-sigs/smb-csi-driver would work on both linux and windows node, and it only provides static provisioning(user should bring their own SMB server address).
Jing Xu
@andyzhangx that's great! Wondering whether we need to open a KEP for this or not in here https://github.com/kubernetes/enhancements/tree/master/keps/sig-windows?
Michelle Au
Would Kubernetes-csi be a good place for a generic smb driver? We already have common build and release infrastructure. Also generic nfs driver is also in the same org.

@msau42 thanks, the new smb driver should be under
https://github.com/kubernetes-csi/csi-driver-smb
Since this driver would work on both linux and windows node, not sure it's necessary to open a KEP on sig-windows.
Anyway, let me work out an initial working version first. Should not take too much time.
Andy Zhang
Update: here is the initial working SMB CSI driver:
https://github.com/csi-driver/csi-driver-smb
Will migrate to https://github.com/kubernetes-csi/csi-driver-smb
Andy Zhang
already created a repo migration tracking issue here: kubernetes/org#1867
