The Amazon FSx for Lustre Container Storage Interface (CSI) Driver implements CSI specification for container orchestrators (CO) to manage lifecycle of Amazon FSx for Lustre filesystems.

The following CSI interfaces are implemented:
- Controller Service: CreateVolume, DeleteVolume, ControllerExpandVolume, ControllerGetCapabilities, ValidateVolumeCapabilities
- Node Service: NodePublishVolume, NodeUnpublishVolume, NodeGetCapabilities, NodeGetInfo, NodeGetId
- Identity Service: GetPluginInfo, GetPluginCapabilities, Probe
The following sections are Kubernetes-specific. If you are a Kubernetes user, use the following for driver features, installation steps and examples.

- Static provisioning - FSx for Lustre file system needs to be created manually first, then it could be mounted inside container as a volume using the Driver.
- Dynamic provisioning - uses persistent volume claim (PVC) to let Kubernetes create the FSx for Lustre filesystem for you and consumes the volume from inside container.
- Mount options - mount options can be specified in storageclass to define how the volume should be mounted.
Notes:
- For dynamically provisioned volumes, only one subnet is allowed inside a storageclass's
parameters.subnetId. This is a limitation that is enforced by FSx for Lustre.
The driver requires IAM permission to talk to Amazon FSx for Lustre service to create/delete the filesystem on user's behalf. There are several methods to grant driver IAM permission:
- Using secret object - create an IAM user with proper permission, put that user's credentials in secret manifest then deploy the secret.
curl https://raw.githubusercontent.com/kubernetes-sigs/aws-fsx-csi-driver/master/deploy/kubernetes/secret.yaml > secret.yaml
# Edit the secret with user credentials
kubectl apply -f secret.yaml- Using worker node instance profile - grant all the worker nodes with proper permission by attach policy to the instance profile of the worker.

}kubectl apply -k "github.com/kubernetes-sigs/aws-fsx-csi-driver/deploy/kubernetes/overlays/stable/?ref=release-0.8"Alternatively, you could also install the driver using helm:
helm repo add aws-fsx-csi-driver https://kubernetes-sigs.github.io/aws-fsx-csi-driver/
helm repo update
helm upgrade --install aws-fsx-csi-driver --namespace kube-system aws-fsx-csi-driver/aws-fsx-csi-driverIn the master branch and the next release there are breaking changes that require you to --force to kubectl apply:
kubectl apply -k "github.com/kubernetes-sigs/aws-fsx-csi-driver/deploy/kubernetes/overlays/stable/?ref=master" --forceVersion 1.0.0 removed and renamed almost all values to be more consistent with the EBS and EFS CSI driver helm charts. For details, see the CHANGELOG.
Before the example, you need to:
- Get yourself familiar with how to setup Kubernetes on AWS and create FSx for Lustre filesystem if you are using static provisioning.
- When creating FSx for Lustre file system, make sure its VPC is accessible from Kuberenetes cluster's VPC and network traffic is allowed by security group.
- For FSx for Lustre VPC, you can either create FSx for lustre filesystem inside the same VPC as Kubernetes cluster or using VPC peering.
- For security group, make sure port 988 is allowed for the security groups that are attached the lustre filesystem ENI.
- Install FSx for Lustre CSI driver following the Installation steps.
- Static provisioning
- Dynamic provisioning
- Dynamic provisioning with S3 integration
- Accessing the filesystem from multiple pods
Please go through CSI Spec and General CSI driver development guideline to get some basic understanding of CSI driver before you start.
