The Amazon Elastic File System (EFS) CSI driver has reached beta status and is now supported by Amazon Elastic Kubernetes Service (EKS). The EFS CSI driver makes it simple to configure elastic file storage for both EKS and self-managed Kubernetes clusters running on AWS using standard Kubernetes interfaces. Applications running in Kubernetes can use EFS file systems to share data between pods in a scale-out group, or with other applications running within or outside of Kubernetes. EFS can also help Kubernetes applications be highly available because all data written to EFS is written to multiple AWS Availability zones. If a Kubernetes pod is terminated and relaunched, the CSI driver will reconnect the EFS file system, even if the pod is relaunched in a different AWS Availability Zone.
