Mountpoint for Amazon S3 CSI driver introduces new access controls for individual Kubernetes pods

The article discusses new access controls for individual Kubernetes pods introduced by the Mountpoint for Amazon S3 CSI (Container Storage Interface) driver. It allows configuring distinct AWS Identity and Access Management (IAM) roles for each pod, providing better data isolation and security in multi-tenant environments.

Specifically, the article covers:

• The CSI driver presents an S3 bucket as a volume accessible by containers in Amazon EKS and self-managed Kubernetes clusters.
• Previously, a single IAM role was used for all pods in the cluster.
• Now, individual IAM roles can be assigned to each pod, restricting access to specific buckets or objects.
• This allows running data-intensive jobs across multiple pods while isolating data access between them.
• The Mountpoint for Amazon S3 CSI driver is supported as an EKS add-on and can be easily installed and configured.
