OpenEBS delivers storage and storage services to containerized environments. OpenEBS allows stateful workloads to be managed more like stateless containers. OpenEBS storage services include: per container (or pod) QoS SLAs, tiering and replica policies across AZs and environments, and predictable and scalable performance. OpenEBS is EBS API comp…

OpenEBS enables the use of containers for mission critical, persistent workloads. OpenEBS is containerized storage and related storage services.

OpenEBS allows you to treat your persistent workload containers, such as DBs on containers, just like other containers. OpenEBS itself is deployed as just another container on your host, and enables:storage services that can be designated on a per pod, application, cluster or container level, including:

• Data persistence across nodes, dramatically reducing time spent rebuilding Cassandra rings for example
• Synchronization of data across availability zones and cloud providers
• Use of commodity hardware plus a container engine to deliver seriously scale out block storage
• Integration with orchestrators, so that developer and application intent flows into OpenEBS configurations automatically
• Management of tiering to and from S3 and other targets
• Plus we’re bringing our experience from BSD based containerization and delivering QoS for customers from our CloudByte experience over to OpenEBS - expect to see more intelligence and manageability

Our vision is simple: let’s let storage and storage services for persistent workloads be so fully integrated into the environment and hence managed automatically that is almost disappears into the background as just yet another infrastructure service that works.

Why OpenEBS scales

OpenEBS can scale to include an arbitrarily large number of containerized storage controllers thanks in part to some advancements in the management of metadata which removes a common bottleneck to scale out storage performance. Again, we learned the hard way over the years at CloudByte and are extremely happy to see initial scale out performance figures with OpenEBS; much credit goes to the orchestration and containerization of course as well.

Installation and Getting Started

OpenEBS can be setup in few easy steps. You can get going on GCE to try it out quickly here: https://github.com/openebs/openebs/blob/master/k8s/hyperconverged/tutorial-configure-openebs-gke.md Also, we have a Vagrant environment available that includes a sample Kubernetes deployment and synthetic load you can use to simulate the performance of OpenEBS. Please follow our Getting Started documentation

Status

We are approaching beta stage with active development underway. See our Project Tracker for more details.

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.
