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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# rook-ceph-best-practices Facts cover Rook through v1.21.1 and Ceph through 19.2.7 / 20.2.4. Everything here is version-gated: re-check `references/sources.md` before relying on it for a newer release. ## Version gates | 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 | 1.31–1.37 (1.36 before v1.20.8) | 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. | | v1.21.x | 1.32–1.37 | Squid 19.2.0+, Tentacle 20.2.1+, Umbrella 21.2.0+ | **msgr2 required by default**: kernel clients need 5.11+, else set `network.connections.requireMsgr2: false` before the hop. Rook pins no CSI images. | Ceph lines: Reef 18.2.x is EOL (last 18.2.8, 2026-03-20). Squid 19.2.x …

How to install
mdr add air-gapped/skills/rook-ceph-best-practices@sha256:b96db9f4b12ce952The line at the top of this page pins the label git:20261027.de37ca2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
