The Complete Production SOP: How to Deploy and Run Rook-Ceph Cloud-Native Distributed Storage Orchestration in Autonomous AI Agents
Step-by-step SOP to install and run the Rook-Ceph distributed storage skill in Codex, Claude Code, and Cursor. Automate CephBlockPools, OSDs, and RGW safely.
Technical Overview & Architectural Context
Autonomous coding agents frequently fail when configuring distributed storage on Kubernetes. When instructed to deploy Ceph via Rook, agents often hallucinate invalid CephCluster CRD schemas, hardcode ephemeral disk paths that fail Ceph's raw disk probe requirements, configure dangerous single-replica CephBlockPools in production, or omit crucial CSI driver configuration parameters. These mistakes cause OSD crash loops, unmountable persistent volume claims (PVCs), and silent data loss risks during node failover events. The 'rook-ceph-cloud-native-storage' skill injects deterministic operating boundaries directly into agent context windows. By formalizing declarative manifest standards, strict resource ordering (CRDs -> Operator -> Cluster -> Pools -> StorageClasses), and automated ceph-tools verification procedures, this skill ensures agents like Claude Code, Codex, and Cursor generate idempotent, production-ready storage architecture without human intervention.

Step-by-Step Execution Playbook
Local Skill Manifest Mounting & Runtime Injection
Create the local skills directory and install the validated SKILL.md file for dynamic agent runtime discovery.
Autonomous runtimes parse local project or home directory SKILL.md manifests to bind procedural rules and system execution triggers. By placing the manifest in `.agents/skills/rook-ceph-cloud-native-storage/SKILL.md` (or your platform's skill directory), runtimes such as Claude Code and Cursor auto-load these deterministic storage constraints during invocation.

# Rook-Ceph Cloud-Native Distributed Storage Orchestration
Orchestrates Ceph on Kubernetes with Rook: managing OSDs, CephBlockPools, CephFilesystems (CephFS), RGW object stores, dynamic CSI volume provisioning, and scrubbing drive failures.
## Execution SOP & Rules
1. Deploy Rook Operator: apply crds.yaml, common.yaml, and operator.yaml in strict topological sequence.
2. Create CephCluster resource specifying storage nodes, raw device filters, and dedicated failureDomain.
3. Define CephBlockPool (minimum 3 replicas) and corresponding StorageClass with reclaimPolicy: Delete or Retain.
4. Monitor Ceph health status via rook-ceph-tools pod running ceph status and ceph df.

---Setting `shell_exec: false` forces the AI agent to output pure, audited YAML manifests to the workspace rather than running high-privilege `kubectl apply` commands directly on cluster nodes.
Do not rename the YAML frontmatter key `triggers`. Runtimes use exact string matching or semantic vector search against these trigger terms to load the skill into the immediate context.
Validate Cluster Hardware Constraints & Prerequisites
Ensure worker node disks meet Rook-Ceph OSD criteria before manifest generation.
Ceph OSDs require unformatted, partition-free disks without existing filesystems or LVM volume groups. AI agents must execute inventory commands to identify valid device paths or filters (such as `deviceFilter: '^sd[b-z]'`) to prevent OSD preparation jobs from failing silently.
kubectl get nodes -o wide && kubectl get nodes -o jsonpath='{range .items[*]}{.metadata.name}{"\n"}{end}'Instruct your agent to write a preflight verification script checking node disks via `lsblk -f` inside an ephemeral debug pod before deploying CephCluster manifests.
Disks previously formatted with ext4/xfs contain signatures that cause Rook OSD preparation to skip the device. Wipe signatures with `wipefs -a /dev/<device>` if re-provisioning.
Intent Matching & Declarative Ceph Manifest Generation
Prompt the agent using frontmatter triggers to generate a complete CephCluster and CephBlockPool manifest set.
When prompted with triggers like 'deploy rook ceph cluster' or 'create ceph block pool', the skill guides the agent to emit production-grade CRDs conforming to Rook v1.13+ specifications, including monitoring and CSI driver configurations.
Keep prompts task-oriented. Explicitly state the target failure domain (host vs. rack) and device filter to prevent the agent from defaulting to `useAllDevices: true`.
Using `useAllDevices: true` on virtualized nodes can accidentally claim OS partitions, leading to unrecoverable node corruption.
Verification, Linting & Output Quality Gate
Run kubeconform and YAML linters against agent outputs prior to cluster application.
The skill enforces an automated quality gate requiring the agent to validate manifest syntax against official Kubernetes and Rook OpenAPI schemas.
yamllint -d relaxed manifests/rook-ceph/ && kubeconform -kubernetes-version 1.28.0 -strict manifests/rook-ceph/Instruct the agent to review the `git diff` on generated manifests to verify that replication size (`size: 3`) and CSI provisioner namespaces match the target cluster setup.
Ensure custom CRD schemas for CephBlockPool and CephCluster are accessible to `kubeconform` or pass CRD validation flags to prevent false schema validation errors.
Real-World Scenario: Production Ceph Block Pool & StorageClass Provisioning for StatefulSets
“Using the rook-ceph-cloud-native-storage skill, create ceph block pool named 'k8s-fast-rbd' with replication size 3 and generate a corresponding StorageClass named 'rook-ceph-block' using retain reclaim policy and ext4 filesystem.”
Runtime Troubleshooting & Failure Modes
Root Cause: The node disk targeted by the CephCluster spec contains existing partition tables, LVM metadata, or filesystem superblocks, causing Ceph's disk initialization probe to abort for data safety.
kubectl -n rook-ceph exec -it $(kubectl -n rook-ceph get pod -l app=rook-ceph-tools -o jsonpath='{.items[0].metadata.name}') -- zap-device /dev/sdb || sgdisk --zap-all /dev/sdbRoot Cause: Ceph CSI RBD node plugin pod encountered a stale gRPC lock or lost sync with Ceph MON quorum during dynamic volume provisioning.

Q:Can I use Rook-Ceph Cloud-Native Distributed Storage Orchestration across Codex, Claude Code, and Cursor simultaneously?
Yes. The skill conforms to the universal SKILL.md specification. All modern agents (Claude Code, Codex, Cursor, Windsurf) parse the standardized YAML frontmatter triggers and SOP instructions seamlessly.
Q:How does Rook-Ceph Cloud-Native Distributed Storage Orchestration prevent context window overflow during long agent sessions?
The skill provides ultra-focused operational rules and explicit schema expectations rather than bundling mega-prompts. Agents reference concise CRD boundaries on-demand without carrying excessive context overhead.
Q:Does this skill require escalated root or container permissions?
No. The skill is audited with a 98/100 security score and specifies shell_exec: false and workspace-only filesystem write privileges, keeping execution sandboxed and production-safe.
