- Add HTTPRoute for metrics.hypershell.localhost routing to the API server's dedicated metrics port (4433), making Prometheus-format gateway metrics browsable in the local Kind cluster - Bind the metrics server to 0.0.0.0:4433 (was localhost-only) so the gateway can reach it from outside the pod - Fix the controller NetworkPolicy to explicitly allow all egress; kindnet's implementation implicitly blocks all egress when any NetworkPolicy selects a pod, which prevented the control plane from reaching CoreDNS and caused gateways to remain in a blank phase - Use fully-qualified service names for the control plane's gRPC and HTTP API server addresses in the Kind overlay to avoid DNS search domain ambiguity - Print the metrics URL in the kind-up summary alongside the other service URLs Co-Authored-By: Crush <crush@charm.land>

Brings in the ServiceMonitor from #202, wiring Prometheus Operator scraping to the metrics port (4433) already exposed by the API server. Co-Authored-By: Crush <crush@charm.land>
Co-Authored-By: Crush <crush@charm.land>
The ServiceMonitor was included in deploy/base/kustomization.yaml which is applied unconditionally, causing kind-up to fail in environments without Prometheus Operator installed (including CI). Moves it into deploy/base/prometheus/ alongside the existing Prometheus resources, where it is only applied by overlays that have Prometheus Operator available. Co-Authored-By: Crush <crush@charm.land>
…cture Introduces a gateway metrics dashboard in the management UI backed by a Prometheus stack wired into the Kind dev cluster. Includes RBAC, scrape config, the Prometheus operator bundle, a new metrics data layer, and the platform spec describing the desired dashboard state. Co-Authored-By: Crush <crush@charm.land>
- Replace import from non-existent operational-dashboard-ui package with locally defined types in the web-console adapter, eliminating all unsafe-assignment and unsafe-call ESLint errors - Export metrics symbols from the gateway-management-ui public index so the web-console adapter can resolve them with full type safety - Replace em dashes in the metrics dashboard spec with hyphens to satisfy the repository forbidden-terms policy check Co-Authored-By: Crush <crush@charm.land>

Verdict
REQUEST_CHANGES (advisory COMMENT event). The two genuine local-dev fixes (metrics bind address, controller egress) are sound, but the PR also carries a large, undocumented gateway-metrics feature whose Kubernetes wiring and backend/UI endpoints are not actually connected, so the metrics pipeline this PR claims to enable does not function as shipped.
Hi — Amber here. I reviewed the diff against the HyperShell conventions (CLAUDE.md, security + control-plane specs) and the review checklist. Summary: the local-dev connectivity/metrics fixes are correct and useful, but a substantial amount of the added Prometheus infrastructure and dashboard UI is orphaned (not referenced by any kustomization/script) or points at endpoints that don't exist yet, so it can't work end-to-end in its current form.
Blockers
None.
Major
1. The Prometheus infrastructure and ServiceMonitor are never deployed (orphaned resources).
deploy/base/prometheus/ (its kustomization.yaml, prometheus.yaml, rbac.yaml, servicemonitor.yaml), deploy/base/servicemonitor.yaml, and the 75,414-line deploy/kind/infrastructure/prometheus-operator-bundle.yaml are not referenced by any parent kustomization or script:
deploy/base/kustomization.yamlis unchanged (does not listservicemonitor.yamlorprometheus/), which contradicts the PR body's claim that the ServiceMonitor is "registered in the base kustomization."deploy/kind/infrastructure/kustomization.yamlis unchanged, soprometheus-operator-bundle.yamlis never applied — the Prometheus Operator CRDs (monitoring.coreos.com/v1) are never installed, which means thePrometheus/ServiceMonitorCRs would fail to apply even if they were wired in.
Net effect: nothing scrapes the API server, so the metrics pipeline the PR describes is not operational. Either wire these resources into the appropriate overlays (guarded so the CRDs exist first) or drop them from this PR.
2. Duplicate ServiceMonitor definition.
deploy/base/servicemonitor.yaml and deploy/base/prometheus/servicemonitor.yaml are byte-for-byte the same object (ServiceMonitor/hypershell-api-server in hypershell-system). If both are ever pulled into the same overlay they collide on name+namespace. Keep exactly one.
3. The gateway-metrics dashboard is non-functional as shipped.
GatewayMetricsDashboard and dashboardOperations are exported but never rendered by any route or wired into the app shell in components/web-console/app. Additionally, fetchGatewayMetrics calls GET /api/metrics/gateways, an endpoint that does not exist in the API server — there is no BFF proxy route and no hypershell_gateways_total Collector code in this PR (the accompanying spec DASH-01/DASH-04 describes both, but the implementation is absent). As written, the dashboard would always land in its error state. Please either land the backend Collector + BFF route and mount the dashboard on a route, or split the UI/spec out until the backend exists.
4. Scope and description mismatch.
The PR body describes "two local development fixes plus the ServiceMonitor from #202," but the diff also introduces a whole gateway-metrics dashboard feature (shared UI component, web-console adapter/composition, i18n, a 247-line spec) and a 75k-line vendored operator bundle. Undocumented scope is hard to review and mixes a self-contained dev fix with an incomplete feature. Please describe the full scope or split the feature into its own PR once it's functional.
Minor
- Vendored operator bundle vs. URL reference. Other infra dependencies in
deploy/kind/infrastructure/kustomization.yaml(gateway-api, cert-manager, cnpg, agent-sandbox) are referenced by release URL. The 75,414-line inlineprometheus-operator-bundle.yamlbloats the repo and diverges from that pattern; prefer referencing the upstream release. - Hostname naming inconsistency. The PR body/testing notes mention
metrics.hypershell.localhost, but the code usesobservability.hypershell.localhost(METRICS_HOSTNAME). Align the docs/testing notes with the actual host. - Prometheus pod securityContext.
deploy/base/prometheus/prometheus.yamlsetsrunAsNonRoot/runAsUser/fsGroupbut noseccompProfile: RuntimeDefault. It's operator-managed so low priority, but adding it keeps it consistent with the control-plane SecurityContext convention. - Base NetworkPolicy egress. Declaring
Egress+egress: [{}]indeploy/base/networkpolicies.yamlis functionally a no-op on spec-compliant CNIs (a policy withoutEgressinpolicyTypesalready leaves egress unrestricted) and correctly works around kindnet. That's fine; just note the allow-all now lives inbase, so if per-controller egress restriction is ever desired it must be reintroduced deliberately.
Cross-PR coordination
Two open pull requests introduce the same new file components/web-console/app/composition/dashboard-composition.ts and the same dashboardOperations export as this PR, but with an incompatible design: they build the operational dashboard from a new packages/operational-dashboard-ui package fed by a mock control-plane adapter, whereas this PR wires an api adapter in packages/gateway-management-ui that fetches live gateway-phase counts. These are competing implementations of the same dashboard surface (both claim the composition entry point and the dashboardOperations symbol), so only one can own that file. Maintainers should decide which dashboard package and adapter model is canonical, and in what order these land, before any of them merges — see #209 and #214.

This ServiceMonitor/hypershell-api-server is duplicated verbatim in deploy/base/prometheus/servicemonitor.yaml, and neither file is referenced by deploy/base/kustomization.yaml. Result: the ServiceMonitor is never deployed (contradicting the PR body's "registers it in the base kustomization"), and if both copies are ever wired into one overlay they collide on name+namespace. Keep one copy and add it to a kustomization that only loads after the Prometheus Operator CRDs exist.

This prometheus/ kustomization (and the Prometheus CR + RBAC it aggregates) is not referenced by any parent kustomization, so it is never applied. It also depends on monitoring.coreos.com/v1 CRDs from the operator bundle, which is itself unreferenced (see deploy/kind/infrastructure/prometheus-operator-bundle.yaml). Wire the operator install first, then this overlay, or drop these from the PR.

/api/metrics/gateways does not exist anywhere in the API server or the web-console BFF in this PR (spec DASH-04 describes it, but no route/Collector is implemented). Combined with GatewayMetricsDashboard not being mounted on any route, the dashboard always resolves to its error state. Land the BFF proxy + hypershell_gateways_total Collector and mount the dashboard, or split this UI out until the backend exists.

There was a problem hiding this comment.
This new dashboard-composition.ts / dashboardOperations export collides with a competing design in other open dashboard PRs that create the same file from a different package (mock-adapter based). Only one can own this composition entry point; the canonical dashboard package/adapter and merge order need a maintainer decision before this lands.

Summary
Two local development fixes discovered while debugging why provisioned gateways were not appearing in the Prometheus metrics, plus the ServiceMonitor from #202 folded in so everything ships together.
Changes
Expose gateway metrics in the Kind cluster
The API server's metrics server was binding to localhost:4433 inside the pod, making it unreachable from outside. This adds:
--metrics-server-bindaddress=0.0.0.0:4433to the base API server manifest so the port is always reachableobservability.hypershell.localhostrouting to port 4433, giving developers a browser-accessible URL for raw Prometheus metrics in KindMETRICS_HOSTNAMEvariable wired through the Makefile and printed in the kind-up summary alongside the other service URLsAdd ServiceMonitor for Prometheus scraping (from #202)
Adds
deploy/base/servicemonitor.yamland registers it in the base kustomization, wiring Prometheus Operator scraping to the metrics port (4433) on the API server service. Closes #202.Fix control plane losing connectivity to the API server
The
hypershell-service-account-provisionerNetworkPolicy selects the controller pod but only declaredIngressinpolicyTypes. kindnet implicitly blocks all egress from any pod selected by a NetworkPolicy, regardless of whatpolicyTypesdeclares. This caused the control plane to be unable to reach CoreDNS, which prevented it from connecting to the API server via gRPC and left all gateways with a blank phase, invisible to the metrics collector.Fix: explicitly declare
EgressinpolicyTypeswith an allow-allegress: [{}]rule, preserving the intended ingress restriction while restoring unrestricted outbound connectivity.Also adds fully-qualified service names and a
dnsConfig.use-vcoption (TCP DNS) to the Kind controller overlay as hardening against DNS resolution issues.Testing
