SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

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/. 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).

Core Features & Use Cases

  • Cross-component compatibility survey against an embedded registry to guide upgrades.
  • Air-gap ready methodology: offline data sources stored in references/ carry the signals.
  • Phase-based detection and verdict output that can be consumed by runbooks and change-management boards.

Quick Start

Survey a cluster to generate a verdict using the embedded registry data and the canonical survey commands.

Frequently Asked Questions about k8s-components-checker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check Kubernetes component compatibility before upgrading an air-gapped cluster?▼

Check Kubernetes component compatibility by cross-referencing a local registry of 19 stack components against cluster-survey outputs from kubectl, helm, and pluto. This generates evidence-backed upgrade-readiness verdicts entirely offline.

Can I survey RKE2 and Rancher community editions for version skew offline?▼

Yes, you can survey RKE2 and Rancher community editions offline for version skew. The Skill cross-references an embedded compatibility registry stored locally in references, ignoring Prime or EE-gated content entirely.

What is the best way to assess Harvester and Cilium upgrade readiness?▼

Assess Harvester and Cilium upgrade readiness by running a canonical survey that scans 19 stack components against an embedded compatibility registry, producing phase-based detection verdicts for change-management boards.

Does this Skill install Kubernetes components or execute cluster upgrades?▼

No, this Skill does not install Kubernetes components or execute cluster upgrades. It strictly assesses upgrade readiness methodology and is not for tracking per-cluster running state or acting as an inventory system.

How do I detect deprecated Kubernetes APIs in an air-gapped environment?▼

Detect deprecated Kubernetes APIs in an air-gapped environment by running pluto and checking the apiserver_requested_deprecated_apis metric from the operator's workstation, feeding these signals into the compatibility survey.

Why should I use an embedded compatibility registry for Kubernetes drift review?▼

Use an embedded compatibility registry for Kubernetes drift review to ensure evidence-backed verdicts cite per-component compatibility signals locally. This air-gap ready methodology supports offline workflows without requiring external data sources.
