Clarify detection conditions and verify API resource format.

Line 28 uses productbase.v1alpha1.product.alauda.io, which deviates from the standard kubectl resource naming pattern (<plural>.<api-group>) seen in other Alauda resources within the codebase. Confirm this format is correct for Alauda CRDs.

Additionally, lines 46, 49, and 52 state to execute patches "if yes" but do not explicitly address the "no" scenarios: What should users do if the moduleinfo query (line 42) returns no results, or if plugins don't use LocalVolume, or if they only use platform-exclusive nodes? This clarification ensures users know whether to skip those patches or proceed without changes.

around line 28, confirm and correct the kubectl resource name and jsonpath (the
current `productbase.v1alpha1.product.alauda.io` does not follow the usual
`<plural>.<api-group>` pattern): verify the actual CRD name with `kubectl
api-resources` (or `kubectl get crd`) and update the example to use the correct
plural form and jsonpath selector; also update lines 46, 49 and 52 to explicitly
document the "no" branches — state that if the moduleinfo query returns no
results, or plugins do not use LocalVolume, or only use platform-exclusive
nodes, the specified patches should be skipped (or provide the exact alternative
steps to take), so readers know whether to apply or skip each patch.

Provide example outputs and clearer decision logic for detection steps.

Lines 47, 50, 53 use complex jsonpath queries but don't show example outputs. Provide:

  • Sample output when Type:LocalVolume is detected (patch needed)
  • Sample output when storage is not LocalVolume (no patch needed)
  • Explicit decision statements (e.g., "If output shows Type:LocalVolume and nodes are not platform-exclusive, apply the [Plugin Name] patch below")

This reduces ambiguity and helps users confidently determine which patches to apply.

⚠️ Potential issue | 🟡 Minor

Add operational context: timing, verification, and rollback procedures.

The document lacks guidance on:

  • When to apply patches in the upgrade lifecycle (before upgrade starts, during, after initial failure?)
  • Verification that patches were successfully applied
  • Rollback procedure if patches fail or cause unintended side effects
  • Order of operations if multiple plugins need patches (do they need to be sequential or can they be parallel?)

Adding these sections would significantly improve usability and reduce risk of misconfiguration.

Add prerequisite documentation, verification steps, and rollback procedures.

The Problem Resolution section provides ResourcePatch manifests without explaining the prerequisite ResourcePatch operator, how to verify patches were applied, or how to recover if they fail. Additionally, the hardcoded target labels (e.g., fb6047e14c28909f84766d7902c9b546) are never explained—users won't know if these are universal identifiers or require customization for different environments.

Add:

  • What the ResourcePatch operator is and whether it must be pre-installed (if so, link to installation docs)
  • Verification commands after applying patches (e.g., kubectl get resourcepatch, checking that nodeSelector was removed from the target resources)
  • Rollback instructions if patches fail or cause issues
  • Clarification on whether hardcoded target labels are environment-specific or universal across all deployments
  • How to adapt resource names (kube-prometheus-0, cpaas-system, etc.) if your environment uses different naming
