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
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.
