AWS EFS CSI Driver¶

This add-on deploys the AWS EFS CSI driver into an EKS cluster.

Usage¶

The AWS EFS CSI driver can be deployed by enabling the add-on via the following. Check out the full example to deploy an EKS Cluster with EFS backing the dynamic provisioning of persistent volumes.

  enable_aws_efs_csi_driver = true

You can optionally customize the Helm chart that deploys the driver via the following configuration.

  enable_aws_efs_csi_driver = true

  # Optional aws_efs_csi_driver_helm_config
  aws_efs_csi_driver = {
    repository     = "https://kubernetes-sigs.github.io/aws-efs-csi-driver/"
    chart_version  = "2.4.1"
  }
  aws_efs_csi_driver {
    role_policies = ["<ADDITIONAL_IAM_POLICY_ARN>"]
  }

Once deployed, you will be able to see a number of supporting resources in the kube-system namespace.

$ kubectl get deployment efs-csi-controller -n kube-system

NAME                 READY   UP-TO-DATE   AVAILABLE   AGE
efs-csi-controller   2/2     2            2           4m29s

$ kubectl get daemonset efs-csi-node -n kube-system

NAME           DESIRED   CURRENT   READY   UP-TO-DATE   AVAILABLE   NODE SELECTOR                 AGE
efs-csi-node   3         3         3       3            3           beta.kubernetes.io/os=linux   4m32s
