    Repair Kubernetes Gateway API Route Weight Stale Reconcile

    Example session with this skill installed

    A blue-green cutover sets 10 percent canary but observed routing stays at old 50 percent.

    Available sources: HTTPRoute YAML, controller reconciliation events (partial excerpts only). Additional evidence requested: gateway listener config, request sample. Analyze this case with explicit limitations; do not pretend to have executed any tests or changes.

    Repair Kubernetes Gateway API Route Weight Stale Reconcile — EVIDENCE-LIMITED REVIEW

    Scenario received

    A blue-green cutover sets 10 percent canary but observed routing stays at old 50 percent.

    Source register

    • S1: HTTPRoute YAML — partial extract available.
    • S2: controller reconciliation events — partial extract available.
    • S3: gateway listener config — NOT PROVIDED; REQUIRED FOR VERIFICATION.
    • S4: request sample — NOT PROVIDED; REQUIRED FOR VERIFICATION.

    Concrete findings and verification

    compare spec revision and observed weights — NEEDS VERIFICATION against supplied source excerpts and missing evidence.
    2.

    trace parentRef and listener resolution — NEEDS VERIFICATION against supplied source excerpts and missing evidence.
    3. locate controller stale generation — NEEDS VERIFICATION against supplied source excerpts and missing evidence.
    4. define bounded rollback and probe — NEEDS VERIFICATION against supplied source excerpts and missing evidence.

    Deliverables and review gates

    • route generation matrix: DRAFT ONLY; do not infer unsupported outcomes.
    • weight drift root-cause options: DRAFT ONLY; do not infer unsupported outcomes.
    • safe rollout verification: DRAFT ONLY; do not infer unsupported outcomes.

    Preliminary conclusion

    INCOMPLETE / REVIEW REQUIRED. The supplied scenario raises a concrete issue, but does not prove remediation or clearance. Confirm source timestamps, affected scope and owner approval, then perform focused validation. No external system was accessed or changed.

    About this skill

    Kubernetes Gateway API implementations often fail silently during complex traffic split transitions. When a blue-green deployment or canary rollout is triggered, the controller may report success while the actual data plane remains stale. This skill provides a structured diagnostic workflow to identify exactly why HTTPRoute weight changes are not reconciling in the cluster.

    What it does

    • Weight drift analysis: Compares spec revisions against observed traffic weights to find discrepancies.
    • ParentRef resolution: Traces Gateway listener bindings to ensure the route is correctly attached.
    • Controller trace: Locates stale generations in the controller logic that prevent updates.
    • Rollback planning: Defines bounded, reversible actions to restore traffic stability.

    How it works

    1. Input collection: Provide the HTTPRoute YAML, controller events, and gateway configurations.
    2. Evidence audit: The skill categorizes data as VERIFIED, INFERRED, or UNKNOWN.
    3. Four-check execution: It runs systematic checks on spec revisions, listener resolution, generation drift, and rollback safety.
    4. Verdict delivery: You receive a SUPPORTED or BLOCKED status with a source evidence table and specific root-cause options.

    Frameworks & tools

    Kubernetes Gateway API (v1), HTTPRoute resources, and standard ingress controllers like Istio, Envoy Gateway, or NGINX.

    Why this beats prompting it yourself

    Generic prompts often hallucinate logs or overlook the parentRef status field. This skill enforces a hard gate on evidence, ensuring every diagnostic claim is linked to a specific timestamped record rather than a guess.

    Use cases

    • Debugging a canary rollout stuck at the wrong traffic percentage.
    • Resolving HTTPRoute status messages that report success despite routing errors.
    • Auditing controller reconciliation events during high-risk production cutovers.

    Known limitations

    Requires manual provision of YAML and event logs. It does not execute live cluster commands and relies on the user to redact sensitive data from inputs.

    Frequently Asked Questions

    This skill specifically targets the 'silent failure' mode of Gateway API where status fields report success but the data plane remains stuck, using a structured Four-check execution to find the exact drift between your YAML spec and actual traffic routing.

    The skill is optimized for Kubernetes Gateway API (v1) and is compatible with any controller that implements HTTPRoute, including Istio, Envoy Gateway, NGINX Gateway Fabric, and Kong.

    No direct cluster access is required; you simply provide the skill with your HTTPRoute YAML, controller events, and gateway configurations to initiate the diagnostic audit.

    You receive the full diagnostic workflow, the evidence audit framework for categorizing logs (VERIFIED/INFERRED), and the rollback planning logic to safely restore traffic stability.

    While this skill provides a definitive 'Verdict' (SUPPORTED or BLOCKED) and root-cause options, it does not execute live 'kubectl' commands, ensuring you maintain full control over any changes made to your infrastructure.
