FSx for Windows EKS Nodes

Question

We are looking to add a number of Windows EKS nodes to an already existing Linux EKS node group. The current Node group uses EFS and the EFS CSI Driver. However, the EFS CSI Driver is not supported by Windows. Would we then add an FSx share for the Windows EKS nodes to use, or should we add an EBS node to use the EBS CSI driver? Looking through the docs EBS, FSx, EFS, and EKS and I dont see this pointed out anywhere. 
Any information would be helpful.

https://aws.github.io/aws-eks-best-practices/windows/docs/storage/ says to use In-tree Volume Plugin: awsElasticBlockStore. However, following that link shows it to be deprecated as of version 1.17 (up to 1.25 i think now).

Accepted Answer

Hi There

Kubernetes Container Storage Interface (CSI) allows central control of different persistent storage options in the Kubernetes cluster. With the addition of the CSI proxy to the Amazon EKS Optimized Windows AMI, customers can now easily use CSI in their Windows workloads running on Amazon EKS.

Take a look at this blog post: https://aws.amazon.com/blogs/modernizing-with-aws/using-smb-csi-driver-on-amazon-eks-windows-nodes/

Also, you can use FSx as a solution for both Linux and Windows nodes using the above information.  See also https://aws.amazon.com/blogs/containers/using-amazon-fsx-for-windows-file-server-as-persistent-storage-on-amazon-eks/ for info on connecting Linux nodes to FSx.
