OpenEBS is containerized storage for containers integrated tightly into K8S and other environments and based on distributed block storage and containerization of storage control. OpenEBS derives intent from K8S and other YAML or JSON such as per container QoS SLAs, tiering and replica policies, and more. OpenEBS is EBS API compliant as well.

OpenEBS is purpose built storage for containerized environments, written in GoLang, built upon block storage containers we call Virtual Storage Machines or VSMs.

Some of the features provided by a single VSM are:

  • is a set of fully isolated block storage containers,
  • has it's own iSCSI stack,
  • full set of storage management APIs,
  • can distribute application consistent data to another VSM or an S3 compatible storage.

Performant Storage Delivered

OpenEBS can scale to an arbitrarily large number of VSMs as it manages the metadata of the block storage system at a file level. The block storage for each VSM is managed as one single file or directory. Further, the IO to this file is managed through large size chunks rather than the typical small size blocks. This enables OpenEBS to deliver higher performance for each VSM and to scale to a large number of VSMs.

Installation and Getting Started

OpenEBS can be setup in few easy steps either on Physical Machines or VMs. Please follow our Getting Started documentation

Show me the Code

This is a meta-repository for OpenEBS. Here please find various documentation related artifacts and code related to integrating OpenEBS with popular orchestration engines like kubernetes, swarm, mesos, rancher, etc., The core storage and storage orchestration source code is distributed in other repositories under the OpenEBS organization. Please start with the pinned repositories or with OpenEBS Architecture document.
