Author: Chris Henzie (Google) With the release of
Kubernetes v1.27 the ReadWriteOncePod feature has graduated to
beta.In this blog post, we'll take a closer look at this feature,
what it does, and how it has evolved in the beta release.
What is ReadWriteOncePod?
ReadWriteOncePod is a new access mode for PersistentVolumes (PVs) and PersistentVolumeClaims (PVCs) introduced in
Kubernetes v1.22.This access mode enables you to restrict volume
access to a single pod in the cluster, ensuring that only one pod
can write to the volume at a time.
