nilsandClaude Opus 5.5 59ee2cae3b Deploy server 2.1.0; keep filled-in secrets out of git
- kustomization pins mg4-server 2.1.0 by digest; server.yaml sets
  PUBLIC_URL for the pairing QR code; the secrets template gains
  APPROVAL_PASSWORD.
- Filled-in Secrets now go into k8s/secrets.yaml, which is gitignored;
  the template stays on placeholders. This follows a leak where real
  values typed into the template were committed and pushed (amended and
  force-pushed since; both values regenerated).
- SPECS.md records pairing and the incident.

# Kubernetes manifests — car.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.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.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>`).
