What

Updates the CSI driver subchart dependencies in the hyperpod-inference-operator Helm chart:

Dependency Chart name From To
S3 CSI aws-mountpoint-s3-csi-driver 1.14.1 2.7.0
FSx CSI aws-fsx-csi-driver 1.11.0 1.17.0

Also bumps the inference-operator chart version 2.4.0 -> 2.5.0, the matching dependency pin in the umbrella HyperPodHelmChart/Chart.yaml, and regenerates Chart.lock.

Notes / upgrade impact

FSx CSI 1.11.0 -> 1.17.0 — no breaking changes; additive Helm values and dependency/registry bumps only.

S3 CSI 1.14.1 -> 2.7.0 — crosses the v1->v2 major boundary. Mountpoint now runs in dedicated unprivileged pods (in a mount-s3 namespace) instead of host systemd processes, and introduces the MountpointS3PodAttachment (s3pa) CRD.

  • Existing PV/PVC specs (volumeHandle, volumeAttributes, mountOptions) remain compatible; no changes needed to s3_persistent_volume.yaml or the chart's values.yaml (the removed node.podInfoOnMountCompat.enable value is not referenced here).
  • IMDS hop limit must be >= 2 for Mountpoint pods to reach IMDS.
  • On Kubernetes < 1.30, the s3.csi.aws.com CSIDriver object must be deleted as part of the upgrade (podInfoOnMount is immutable pre-1.30).
  • Host-shared cache folders are no longer supported (use Mountpoint pod sharing).

Ref: S3 CSI v1->v2 upgrade guide.

Testing

helm dependency update resolves all subcharts; helm lint passes with required install values supplied (eksClusterName, tlsCertificateS3Bucket, region, etc.).

Update the aws-mountpoint-s3-csi-driver and aws-fsx-csi-driver
subchart dependencies in the hyperpod-inference-operator chart:

- aws-mountpoint-s3-csi-driver: 1.14.1 -> 2.7.0
- aws-fsx-csi-driver: 1.11.0 -> 1.17.0

Bump the inference-operator chart version 2.4.0 -> 2.5.0 and the
matching dependency pin in the umbrella HyperPodHelmChart, and
regenerate Chart.lock.

Note: the S3 CSI v2 line is a major release (Mountpoint now runs in
dedicated pods instead of host systemd processes). Existing PV/PVC
specs (volumeHandle, volumeAttributes, mountOptions) remain
compatible. Operators must ensure the IMDS hop limit is >= 2, and on
Kubernetes < 1.30 the s3.csi.aws.com CSIDriver object must be deleted
as part of the upgrade.
