harvester-upgrade
SolidPlan and run a controlled, COMMUNITY-edition Harvester HCI upgrade off an EOL line up to latest stable — the no-skip minor ladder (1.5→1.6→1.7→1.8; embedded RKE2/KubeVirt/Longhorn/SLE-Micro ride along), gated at each hop on first upgrading the EXTERNAL Rancher + a matching Harvester UI-extension (1.6↔Rancher 2.12, 1.7↔2.13, 1.8↔2.14). Covers air-gapped version detection, why node-upgrade order is NOT operator-choosable (forced serial; the pause knob is v1.7.0+ only) and how to protect VM-hosted control planes anyway via anti-affinity spread + N+1 live-migration, making self-managed RKE2 guests Harvester-aware (cloud-provider, CSI, qemu-guest-agent), per-hop breaking changes (wicked→NetworkManager, Intel NIC rename, DHCP IP churn), the enforced pre-flight health gates, and the no-downgrade backup/rollback reality. Companion to k8s-components-checker and rancher-upgrade.

rancher-upgrade
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→2.14, 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 embedded-CAPI→Rancher-Turtles migration, Fleet coupling, cert-manager/Helm/backup prerequisites, backup- restore-operator + etcd rollback, and the air-gapped upgrade procedure (which images/charts/KDM to mirror). Assumes the Helm-on-Kubernetes install. Community editions only; Prime content excluded. Companion to k8s-components-checker, which owns the management-cluster k8s compatibility verdict; this skill owns the upgrade methodology and downstream coordination.
k8s-components-checker
Survey an RKE2 community cluster against an embedded compatibility registry of 19 stack components and produce a verdict for upgrade-readiness, drift-review, and version-skew questions. Components: RKE2, Rancher, Harvester, Cilium, Tetragon, cert-manager, Kyverno, KEDA, Argo CD, Harbor, Traefik, Rook, Ceph, OpenEBS, GitLab, ECK, Zalando postgres-operator, Grafana Mimir, NVIDIA GPU Operator. Works air-gapped — compatibility data lives in `references/compat/`. Surveys run via `kubectl` + `helm` + `pluto` + the apiserver `apiserver_requested_deprecated_apis` metric from the operator's workstation. Community editions only — Prime/EE-gated content is ignored. NOT for installing components, NOT for executing upgrades, NOT for tracking per-cluster running state (the registry is methodology, not inventory).
rancher-logging-exit
Migrate off the Rancher-bundled `rancher-logging` chart (cattle-logging-system, rancher/mirrored-kube-logging-* images) to the upstream kube-logging logging-operator ≥6.7.0 — air-gap-first. Rancher 2.11 through 2.15-dev all bundle a frozen operator 4.10.0 that is inside the affected range of CVE-2026-54680 (CVSS 9.9 config-injection RCE, no SUSE fix) — so the exit is security-urgent. Covers the maintainer-endorsed helm-release-secret strategy (near-zero gap; NOT `helm uninstall rancher-logging-crd`, which cascade-deletes every CR and the data plane), CR compatibility 4.10→6.7 (silent field pruning), server-side CRD apply (828KB CRDs), buffer-PVC preservation, air-gap image/chart mirroring, rollback, and stale-CRD debris cleanup.
