AmazonEBSCSIDriverPolicyV2

Description: IAM Policy that allows the EBS CSI driver service account to make calls to related services such as EC2 on your behalf. It limits the Amazon EBS CSI driver to only managing EBS volumes and snapshots that are tagged with the key ebs.csi.aws.com/cluster set to true. Volumes provisioned by the in-tree Kubernetes volume plugin (CSI-migrated volumes) are also supported through the kubernetes.io/created-for/pvc/name resource tag.

AmazonEBSCSIDriverPolicyV2 is an AWS managed policy.

Using this policy

You can attach AmazonEBSCSIDriverPolicyV2 to your users, groups, and roles.
