Storage: Volumes, PVs, PVCs & StorageClass
A container's own filesystem is ephemeral. Kubernetes Volumes solve this at increasing levels of durability: emptyDir (Pod-lifetime), PersistentVolume/PVC (cluster-scoped, outlives Pods), and StorageC
Learning objectives
- Explain the relationship between a PersistentVolume, a PersistentVolumeClaim, and a StorageClass.
- Explain what dynamic provisioning actually automates, versus the manual PV-creation approach it replaces.
- Choose an appropriate access mode and StorageClass for a given stateful workload.
