Amazon FSx for Lustre CSI Driver

Overview

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.

CSI Specification Compability Matrix

Container Images

FSx CSI Driver Version Image
master branch amazon/aws-fsx-csi-driver:latest
v0.1.0 amazon/aws-fsx-csi-driver:v0.1.0

Features

  • 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 persistence volume claim (PVC) to let the Kuberenetes to create the FSx for Lustre filesystem for you and consumes the volume from inside container.

Installation

Set up driver permission

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/aws/csi-driver-amazon-fsx/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.

Deploy driver

kubectl apply -f https://raw.githubusercontent.com/aws/csi-driver-amazon-fsx/master/deploy/kubernetes/manifest.yaml

Examples

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.
