What is Rook?

Rook is an open source cloud-native storage orchestrator for Kubernetes, providing the platform, framework, and support for a diverse set of storage solutions to natively integrate with cloud-native environments.

Rook turns storage software into self-managing, self-scaling, and self-healing storage services. It does this by automating deployment, bootstrapping, configuration, provisioning, scaling, upgrading, migration, disaster recovery, monitoring, and resource management. Rook uses the facilities provided by the underlying cloud-native container management, scheduling and orchestration platform to perform its duties.

Rook integrates deeply into cloud native environments leveraging extension points and providing a seamless experience for scheduling, lifecycle management, resource management, security, monitoring, and user experience.

For more details about the storage solutions currently supported by Rook, please refer to the project status section below. We plan to continue adding support for other storage systems and environments based on community demand and engagement in future releases. See our roadmap for more details.

Rook is hosted by the Cloud Native Computing Foundation (CNCF) as an incubating level project. If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Rook plays a role, read the CNCF announcement.

Community Meeting

A regular community meeting takes place every other Tuesday at 9:00 AM PT (Pacific Time). Convert to your local timezone.

Any changes to the meeting schedule will be added to the agenda doc and posted to Slack #announcements and the rook-dev mailing list.

Anyone who wants to discuss the direction of the project, design and implementation reviews, or general questions with the broader community is welcome and encouraged to join.

Project Status

The status of each storage provider supported by Rook can be found in the table below. Each API group is assigned its own individual status to reflect their varying maturity and stability. More details about API versioning and status in Kubernetes can be found on the Kubernetes API versioning page, but the key difference between the statuses are summarized below:

  • Alpha: The API may change in incompatible ways in a later software release without notice, recommended for use only in short-lived testing clusters, due to increased risk of bugs and lack of long-term support.
  • Beta: Support for the overall features will not be dropped, though details may change. Support for upgrading or migrating between versions will be provided, either through automation or manual steps.
  • Stable: Features will appear in released software for many subsequent versions and support for upgrading between versions will be provided with software automation in the vast majority of scenarios.
Name Details API Group Status
Rook Framework The framework for common storage specs and logic used to support other storage providers. rook.io/v1alpha2 Alpha
Ceph Ceph is a distributed storage system that provides file, block and object storage and is deployed in large scale production clusters. ceph.rook.io/v1 Stable
CockroachDB CockroachDB is a cloud-native SQL database for building global, scalable cloud services that survive disasters. cockroachdb.rook.io/v1alpha1 Alpha
Cassandra Cassandra is a highly available NoSQL database featuring lightning fast performance, tunable consistency and massive scalability. Scylla is a close-to-the-hardware rewrite of Cassandra in C++, which enables much lower latencies and higher throughput. cassandra.rook.io/v1alpha1 Alpha
EdgeFS EdgeFS is high-performance and fault-tolerant object storage system with Geo-Transparent data access to file, block or object. edgefs.rook.io/v1alpha1 Alpha
Minio Minio is a high performance distributed object storage server, designed for large-scale private cloud infrastructure. minio.rook.io/v1alpha1 Alpha
NFS Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. nfs.rook.io/v1alpha1 Alpha

Official Releases

Official releases of Rook can be found on the releases page.
