+# ironic-hardware-exporter
+
+RabbitMQ-driven Prometheus exporter for Ironic hardware and node-state metrics.
+
+## Deployment Scope
+
+- Cluster scope: site
+- Values key: `site.ironic_hardware_exporter`
+- ArgoCD Application template: `charts/argocd-understack/templates/application-ironic-hardware-exporter.yaml`
+
+## How ArgoCD Builds It
+
+{{ component_argocd_builds() }}
+
+## How to Enable
+
+Enable this component in your site deployment values:
+
+```yaml title="$CLUSTER_NAME/deploy.yaml"
+site:
+  ironic_hardware_exporter:
+    enabled: true
+```
+
+## Deployment Repo Content
+
+{{ secrets_disclaimer }}
+
+Required or commonly required items:
+
+- `values.yaml`: Provide site-specific Helm values such as RabbitMQ host, queue names, TLS settings, and optional `ServiceMonitor` tuning.
+- `kustomization.yaml`: Include any Secrets or manifests that must be applied alongside the chart from the same deploy-repo directory.
+- `RabbitMQ password Secret`: Create the Secret referenced by `rabbitmq.existingSecret`.
+
+Optional additions:
+
+- `RabbitMQ CA Secret`: Add a Secret containing `ca.crt` when `rabbitmq.tls.enabled=true` and the broker uses a private CA.
+- `Additional overlay manifests`: Add SealedSecrets, ExternalSecrets, NetworkPolicies, or namespace-local overrides if this site needs extra deployment-specific resources.
+
+## Notes
+
+- This component uses a deploy-repo second source, so enabling it should normally create a site directory like `$CLUSTER_NAME/ironic-hardware-exporter/`.
+- The chart itself lives in `go/ironic-hardware-exporter/helm` inside the UnderStack repo.
