rook-ceph-best-practices skillA

rook-ceph-best-practices is agent-read markdown (skill) from air-gapped/skills: Operate, configure and upgrade Rook-managed Ceph on Kubernetes (CephCluster CR; rook-ceph, rook-ceph-cluster and ceph-csi-drivers charts; ceph-csi-operator). Core knowledge: the Rook -> Ceph -> key-rotation upgrade order and its version gates; the CVE-2025-30156 fix (new AES256K CephX key type, daemon key rotation, the six AUTH_INSECURE_* health codes, kernel 7.0 for CSI keys); the Rook v1.20 move of CSI to ceph-csi-operator and the new ceph-csi-drivers chart; disabling the rook mgr module befor.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# rook-ceph-best-practices

Facts verified **2026-09-23** against rook/rook releases v1.16.0–v1.20.7
(unfiltered), the Rook docs at tag v1.20.7, the ceph.io release posts,
the rook/rook and ceph/ceph-csi issue trackers, and one live upgrade
(Rook v1.19.6 → v1.19.11, Ceph 19.2.3 → 19.2.6 with daemon key rotation).
Everything here is version-gated: re-check `references/sources.md` before
relying on it for a newer release.

## Version gates (2026-09-23)

| Rook | Kubernetes | Ceph supported | Notes |
|---|---|---|---|
| v1.18.x | 1.29–1.34 | Reef 18.2, Squid 19.2 | Last line that runs Reef. ceph-csi-operator becomes the default CSI config path. Key rotation experimental. |
| v1.19.x | 1.30–1.35 | Squid 19.2.0+, Tentacle | **Reef dropped** (min Ceph 19.2.0). AES256K from **v1.19.9**; CVE floor **v1.19.10**. v1.19.11 ships ceph-csi 3.16.3 (AES256K backport). |
| v1.20.x | 1.31–1.36 | Squid 19.2.0+, Tentacle 20.2.1+ | **Rook no longer deploys CSI** — ceph-csi-operator + new `ceph-csi-drivers` chart required. AES256K from v1.20.5; CVE floor **v1.20.6**. v1.20.7 ships ceph-csi 3.17.1. |

Ceph lines: Reef 18.2.x is EOL (last 18.2.8, 2026-03-20). Squid 19.2.x
