OpenEBS Logo

OpenEBS Dynamic Local PV provisioner can be used to dynamically provision Kubernetes Local Volumes using different kinds of storage available on the Kubernetes nodes.

Project Status: GA

Local Persistent Volumes are great for distributed cloud native data services that can handle resiliency and availability and expect low-latency access to the storage. Local Persistent Volumes can be provisioned using the hostpath, NVMe or PCIe based SSDs, Hard Disks or on top of other filesystems like ZFS, LVM.

Some of the targetted applications are:

  • Distributed SQL Databases like PostgreSQL
  • Distributed No-SQL Databases like MongoDB, Cassandra
  • Distributed Object Storages like MinIO (distributed mode)
  • Distributed Streaming services like Apache Kakfa,
  • Distributed Logging and search services like ElasticSearch, Solr
  • AI/ML workloads

Overview

Kubernetes Local persistent volumes allows users to access local storage through the standard PVC interface in a simple and portable way. The PV contains node affinity information that the system uses to schedule pods to the correct nodes. Features:

  • Supports using hostpath as well for provisioning a Local PV. In fact in some cases, the Kubernetes nodes may have limited number of storage devices attached to the node and hostpath based Local PVs offer efficient management of the storage available on the node.
