- k8s/grafana.yaml: Grafana 13.2.3 with a 1Gi PVC, sign-up and
anonymous access off. The InfluxDB datasource (URL and token from the
environment) and three dashboards — Live, Consumption, Charging — are
provisioned from k8s/grafana/ via kustomize-generated ConfigMaps.
- server.yaml for the Go server (port 8080, UID 65532, smaller limits),
image tag 2.0.0. The NetworkPolicy now admits Grafana to InfluxDB.
- ingress.yaml: IngressRoutes for car.stinnesbeck.com and Grafana
(placeholder host car-grafana.stinnesbeck.com) with tls: {}, using
Traefik's default certificate; the cert-manager Certificate is gone.
- secrets.example.yaml: drops the dashboard secrets, adds grafana-admin.
- AGENTS.md loses its Next.js block; SPECS.md describes the new setup.
The removal of web/ (the Next.js app) and of the stale .next/ cache
upstream had committed already landed in 51e6f6f, which was staged
together with the Go server by mistake.
Checked end to end in podman (Go server + InfluxDB 2.7.12 + Grafana
13.2.3): all 25 dashboard queries return the expected data, and the
dashboards were rendered with headless Chromium. Manifests validated
offline with kustomize and kubeconform. Nothing applied to a cluster.
