Kubernetes 1.29: Single Pod Access Mode for PersistentVolumes Graduates to Stable

Kubernetes v1.29 introduces ReadWriteOncePod, a volume access mode that restricts writes to a single pod. This mode enhances security and is particularly beneficial for stateful workloads requiring single-writer access. It's available in Kubernetes v1.27 and later, and always recognized in v1.29 and beyond. To use ReadWriteOncePod, create a PVC with the appropriate access mode. For CSI volumes, CSI sidecars must be updated to supported versions. Dynamic provisioning creates PVs with the ReadWriteOncePod mode.
