Modify Amazon EBS volumes on Kubernetes with Volume Attributes Classes
Containers Blog
This article introduces the new VolumeAttributesClass (VAC) feature in Amazon EKS 1.31, which allows Kubernetes users to modify Amazon EBS volumes without application downtime.
- Enables online modifications of EBS volume characteristics like IOPS, throughput, and volume type
- Works with Amazon EBS CSI driver version 1.35.0 or later
- Supports three main workflows:
- Performance tuning of volumes
- Migrating to cost-effective gp3 volumes
- Modifying volume tags for backup automation
- Provides a declarative way to manage persistent volumes
- Allows cluster operators to create standard volume configuration classes for application teams
The feature simplifies volume management in Kubernetes by allowing dynamic modifications without requiring application downtime or manual migration.
