Kubernetes Cluster implements persistent data with the help of Persistent Volumes (PV) and Persistent Volume Claims (PVC). PV is storage provisioned by an administrator, which is similar to Volumes but with lifecycle independent of any individual pod. PVC is a request for the PV storage with a specific size and access mode.Jelastic PaaS allows automatically configure NFS volume provisioner during installation. Such a solution automatically provision a persistent volume each time PVC is created. Thus, there is no need to set up PVs with desired AccessMode or StorageClass manually.
The jelastic-dynamic-volume is a default StorageClass in Jelastic Kubernetes Cluster. Herewith, all data is stored in the /data directory.
