Kubernetes applications may need storage that spans machines and provides more than a local disk. Rook manages Ceph on Kubernetes, automating deployment and lifecycle operations around Ceph’s block, file and object storage services. It gives platform teams Kubernetes resources for operating that storage system. The underlying storage still needs a sound design for disks, networks, replication and recovery capacity. A healthy Rook controller does not by itself prove that Ceph’s data is healthy or backed up.
Current guidance
The recovered text describes Rook as a framework for multiple storage systems. Current Rook documentation specifically presents its Ceph operator and Ceph’s block, file and object services. This current scope is more precise than assuming every old Rook backend remains a supported deployment option.
Rook automates Ceph lifecycle operations but does not eliminate storage engineering. Evaluate available devices, failure domains, replica or erasure-coding policy, network capacity and recovery headroom before adopting it. Operator health and Ceph data health are different signals; a running Kubernetes controller does not establish quorum, available capacity or a valid application backup.
Before upgrading an old installation, record Rook/Ceph versions, CRDs, pools, filesystems, object stores, CSI configuration, encryption and device assignments. Follow the supported version sequence and rehearse recovery on separate storage. Preserve application-consistent backups outside the failure domain being changed. Never delete the old storage cluster resource as a shortcut around a chart ownership conflict. This advisory does not claim a tested Ceph upgrade, disk replacement or disaster recovery exercise.
Historical upstream link check · 2026-10-09
The recorded upstream address returned HTTP 404 on 2026-10-09; that URL was unavailable in this check. GitHub does not mark rook/rook archived or disabled; this does not establish active maintenance, support or compatibility. Link availability does not certify the historical installation instructions or current security support. Rook's current Helm overview replaces the removed repository documentation path; historical commands still require review.

Rook is an open source cloud-native storage orchestrator, 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.
Currently Rook manages Ceph storage clusters but there is planned support for Gluster in the future.
