Rook is an open source project that automates the deployment and management of distributed storage systems like Ceph in cloud native environments like Kubernetes. It turns distributed storage software into self-managing, self-scaling, and self-healing storage services. Rook integrates deeply with Kubernetes to provide dynamic volume provisioning, scheduling, security, monitoring and more for storage clusters and pools. It currently supports Ceph and Kubernetes and aims to support more systems with community help.

2. Rook Overview
• Open Sourced Nov’16 (Apache 2.0)
• Turns distributed storage software into a self-managing, self-scaling, and self-
healing storage services
• Automates deployment, bootstrapping, configuration, provisioning, scaling, upgrading,
migration, disaster recovery, monitoring, and resource management
• Uses the facilities provided by the underlying cloud-native container management,
scheduling and orchestration platform to perform its duties
• 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.
• Initial support for Ceph and Kubernetes – more to come with community help
• Currently in Alpha, Beta planned in the Fall, Production Ready by end of year

11. Rook and the CNCF
• Well-aligned with CNCF core principles of cloud-native systems:
container packaged, micro-services oriented, and dynamically
managed.
• Complimentary to other CNCF projects like Kubernetes and
Prometheus.
• Integrating storage services helps the CNCF offer a more complete
stack and unlock powerful scenarios around federation, portability
and multi-cloud.
