The Mountpoint for Amazon S3 Container Storage Interface (CSI) Driver allows your Kubernetes applications to access Amazon S3 objects through a file system interface. Built on Mountpoint for Amazon S3, the Mountpoint CSI driver presents an Amazon S3 bucket as a storage volume accessible by containers in your Kubernetes cluster. The Mountpoint CSI driver implements the CSI specification for container orchestrators (CO) to manage storage volumes.

For Amazon EKS clusters, the Mountpoint for Amazon S3 CSI driver is also available as an EKS add-on to provide automatic installation and management.

• Static Provisioning - Associate an existing S3 bucket with a PersistentVolume (PV) for consumption within Kubernetes.
• Mount Options - Mount options can be specified in the PersistentVolume (PV) resource to define how the volume should be mounted. For Mountpoint-specific options, take a look at the Mountpoint docs for configuration.

Mountpoint for Amazon S3 does not implement all the features of a POSIX file system, and there are some differences that may affect compatibility with your application. See Mountpoint file system behavior for a detailed description of Mountpoint's behavior and POSIX support and how they could affect your application.
