Chapter 1. Storage overview
MicroShift supports dynamic, ephemeral, and persistent storage, both for on-premise and cloud providers. You can manage container storage for persistent and non-persistent data in a MicroShift node.
1.1. Dynamic storage with the LVMS plugin
MicroShift provides dynamic storage provisioning that is ready for immediate use with the logical volume manager storage (LVMS) Container Storage Interface (CSI) provider. Dynamic provisioning creates storage volumes on-demand, eliminating the need for pre-provisioned storage.
1.2. Ephemeral storage
Pods and containers are ephemeral or transient in nature and designed for stateless applications. Ephemeral storage allows administrators and developers to better manage the local storage for some of their operations.
1.3. Persistent storage
Persistent storage in MicroShift enables stateful applications to retain data beyond the lifecycle of individual pods. You can use persistent volumes (PVs) to provision storage and persistent volume claims (PVCs) to request storage for your applications.
1.4. Dynamic storage provisioning
In MicroShift, dynamic storage provisioning creates persistent volumes when applications request storage. You can scale your storage workloads on-demand, without manually preallocating storage.
