Kubernetes Cluster: Persistent Volume Claim

Anytime your application pod needs access to the Persistent Volume (PV), a dedicated PersistentVolumeClaim (PVC) with a specific amount of storage and particular access mode is requested. Herewith, Jelastic PaaS does not restrict PVCs in any way (including creation). However, there are a few things that you should take into consideration when working with the persistent volume claims:
  • if you specify a StorageClass other than the default jelastic-dynamic-volume one, PV should be created in advance
  • when several pods should use the same PV, ensure that it supports ROX or RWX AccessMode
