Kubernetes Volumes allows to store data independent of Container restarts. Volumes in Kubernetes are different that Docker Volumes.[1]

Kubernetes supports different type of volumes [2]:

  • Cloud providers: awsElasticBlockStore, azureDisk, azureFile
  • Storage technologies: fc (fibre channel)[3], iscsi
  • Networked filesystems: cephfs, nfs, glusterfs
  • Others:
    • cinder, configMap, CSI, downwardAPI
    • emptyDir: the data in the emptyDir is deleted forever when Pod is removed from a node.
    • flexVolume[4], can be expanded [5]
    • flocker, gcePersistentDisk, hostPath, local, persistentVolumeClaim, projected, portworxVolume, quobyte, rbd, scaleIO, secret, storageos, vsphereVolume
    • Support for raw block storage in CSI (v1.18, March 2020)
  • Deprecated: gitRepo

Persistent volumes subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed.
