Summary

The ServiceMonitor at flux/vin-decoder/servicemonitor.yaml references port: http (name-based lookup), but the vin-decoder Service had an anonymous port (port: 80, targetPort: 3000) and the container had no named port.

Prometheus ServiceMonitor port discovery requires the port name to match between the Service spec and the ServiceMonitor endpoints[].port field. Without a matching named port, Prometheus would fail to discover the scrape target and no metrics would be collected.

Changes

flux/vin-decoder/helmrelease.yaml: Added name: http to the container containerPort: 3000
flux/vin-decoder/helmrelease.yaml: Added name: http to the Service port (port: 80 -> targetPort: 3000)

Validation

kustomize build flux/ = PASS ✅

## Summary The `ServiceMonitor` at `flux/vin-decoder/servicemonitor.yaml` references `port: http` (name-based lookup), but the vin-decoder Service had an anonymous port (`port: 80, targetPort: 3000`) and the container had no named port. Prometheus ServiceMonitor port discovery requires the port **name** to match between the Service spec and the ServiceMonitor `endpoints[].port` field. Without a matching named port, Prometheus would fail to discover the scrape target and no metrics would be collected. ## Changes - `flux/vin-decoder/helmrelease.yaml`: Added `name: http` to the container `containerPort: 3000` - `flux/vin-decoder/helmrelease.yaml`: Added `name: http` to the Service port (`port: 80 -> targetPort: 3000`) ## Validation - `kustomize build flux/` = PASS ✅ ## Related - Closes leeworks-agents/api-company#174 (VIN Decoder metrics instrumentation — ServiceMonitor scrape config fix)

The ServiceMonitor at flux/vin-decoder/servicemonitor.yaml references port
by name ('http'), but the Service had anonymous port 80 -> 3000 and the
container had no named port. Prometheus ServiceMonitor port matching requires
the port name to match between the Service and the ServiceMonitor spec.

Adds:
- name: http to the containerPort (port 3000)
- name: http to the Service port (port 80 -> targetPort 3000)

This allows the kube-prometheus-stack ServiceMonitor to correctly scrape
/metrics from vin-decoder pods.

Closes leeworks-agents/api-company#174
