rancher-upgrade SKILL.md skillA
rancher-upgrade from air-gapped/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Plan and sequence COMMUNITY-edition Rancher upgrades across air-gapped multi-cluster fleets — a management/"hosting" Rancher cluster plus the downstream RKE2/K3s clusters it provisions. Covers the community release model (2.11→2.15, community-vs-Prime cadence, EOL), the Kontainer Driver Metadata (KDM) matrix deciding which downstream k8s minors each Rancher version can manage (and the stranding risk when a host-Rancher bump outruns its sub-clusters), cross-cluster upgrade ordering, the…
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
# rancher-upgrade
Plan, sequence, and de-risk a **community-edition Rancher** upgrade across a real fleet: a
management ("hosting") cluster and the downstream RKE2/K3s clusters it provisions. The hard part
of a Rancher upgrade is almost never the `helm upgrade` itself — it's the **cross-cluster
coordination**: a management-cluster Rancher bump silently changes which downstream Kubernetes
versions the fleet can run, and getting the order wrong strands sub-clusters or forces a rebuild.
**Community editions only.** SUSE Rancher Prime backports, Prime-only patches, and Prime support
matrices are out of scope — flag them when they appear, never build a plan on them. House Rule #1.
## Companion to k8s-components-checker — who owns what
This skill is the upgrade-methodology companion to `k8s-components-checker` (same repo), mirroring
the `argo-cd-apps ↔ compat/argo-cd.md` split. The boundary is load-bearing — respect it to avoid
drift:

How to install
mdr add air-gapped/skills/rancher-upgrade@sha256:690c727c4c45889fThe line at the top of this page pins the label git:20261004.95930c6, 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.
