The server's host is car.k8s.stinnesbeck.com, not car.stinnesbeck.com: IngressRoute, PUBLIC_URL (so the pairing QR code points there), the app's pre-filled server URL and hint, and the docs. Grafana's placeholder host follows to car-grafana.k8s.stinnesbeck.com, so one *.k8s.stinnesbeck.com default certificate covers both. App 2.4.1 for the new default; the server image is unchanged (its URL comes from the manifest).

# Kubernetes manifests — car.k8s.stinnesbeck.com
|
|
|
|
Plain manifests for the car server, InfluxDB 2 and Grafana. They are only files: nothing here
|
|
is applied automatically. Apply them yourself.
|
|
|
|
| File | What |
|
|
|---|---|
|
|
| `namespace.yaml` | Namespace `mg4` |
|
|
| `influxdb.yaml` | InfluxDB 2.7.12 StatefulSet (10Gi PVC, default storage class), cluster-internal Service, NetworkPolicy admitting only the server and Grafana |
|
|
| `server.yaml` | Go server Deployment (1 replica, non-root, read-only root filesystem) and Service |
|
|
| `grafana.yaml` | Grafana 13.2.3 Deployment (1Gi PVC), Service; datasource and dashboards provisioned |
|
|
| `grafana/` | The provisioned InfluxDB datasource and the MG4 dashboards (Live, Consumption, Charging) |
|
|
| `ingress.yaml` | Traefik `IngressRoute`s for car.k8s.stinnesbeck.com and Grafana, TLS from Traefik's default certificate |
|
|
| `secrets.example.yaml` | **Template** for the Secrets; placeholders only, not in `kustomization.yaml` |
|
|
| `secrets.yaml` | Your filled-in copy — **gitignored**, never committed |
|
|
| `kustomization.yaml` | Everything except the Secrets; pins the server image, generates the Grafana ConfigMaps |
|
|
|
|
## Before the first apply
|
|
|
|
1. **Check `ingress.yaml`:** the ingress class (placeholder `traefik-external` for the public
|
|
Traefik) and Grafana's host (placeholder `car-grafana.k8s.stinnesbeck.com`). Both hosts must be
|
|
covered by Traefik's default certificate.
|
|
2. **Create the Secrets.** `cp k8s/secrets.example.yaml k8s/secrets.yaml` (gitignored), replace
|
|
every `CHANGE-ME` there (`openssl rand -hex 32`): `influxdb-auth`, `mg4-server` (ingest token,
|
|
approval password for pairing, your ABRP API key and user token) and `grafana-admin`. Keep
|
|
`secrets.example.yaml` itself on placeholders only.
|
|
3. **Registry access.** The `mg4-server` package on git.stinnesbeck.com is public, so no pull
|
|
secret is needed. If you make it private, add an `imagePullSecrets` entry to `server.yaml`.
|
|
|
|
## Apply
|
|
|
|
```sh
|
|
kubectl apply -f k8s/namespace.yaml
|
|
kubectl apply -f k8s/secrets.yaml
|
|
kubectl apply -k k8s/
|
|
```
|
|
|
|
## Notes
|
|
|
|
- InfluxDB's setup mode runs only on an empty volume. Changing `admin-token` in the Secret later
|
|
does not change the token inside InfluxDB.
|
|
- The server and Grafana use the InfluxDB admin token. A token scoped to the `mg4` bucket (read
|
|
for Grafana, read/write for the server) can replace it later.
|
|
- The dashboards are read-only in Grafana's UI. Change the JSON in `grafana/dashboards/`; the
|
|
ConfigMap name changes with its content, which rolls Grafana.
|
|
- The server image is pinned by digest in `kustomization.yaml`. To upgrade, push a new tag and
|
|
put its digest there (`skopeo inspect docker://git.stinnesbeck.com/nils/mg4-server:<tag>`).
