Kubernetes 1.35 Unlocks Mutable PV Node Affinity – Alpha Feature with Real Risks

Picture this: your zonal disk just got migrated to regional storage, but Kubernetes won't let Pods schedule anywhere new. v1.35's mutable PV node affinity aims to fix that – if you dare enable alpha.

⚡ Key Takeaways

  • Mutable PV node affinity in Kubernetes 1.35 (alpha) enables flexible updates for evolving storage like regional disks.
  • Race conditions risk Pods on invalid nodes; manual syncs with providers required – no auto-magic yet.
  • Step toward CSI/VolumeAttributesClass integration, but expect slow vendor adoption and ops headaches.
