# xslt-playground Helm Chart

This chart deploys the frontend and backend of xslt-playground.

## Configuration

Key parameters in `values.yaml`:

- `image.frontend` and `image.backend` – container images.
- `firebase.enabled` – set to `false` to disable Firebase integration entirely.
  When enabled you must provide a secret named by `firebase.secretName` with the
  keys `firebase.credentialsKey` and `firebase.configKey`. The backend mounts the
  credentials file at `firebase.credentialsMountPath` and the frontend reads the
  config JSON.
- `storage.enabled` – disable database usage when `false`. If enabled the backend
  gets `DATABASE_URL` from `storage.databaseUrl`; otherwise the environment
  variable `DISABLE_DATABASE=true` is set.
- `ingress` – configure ingress for the frontend service. The backend is exposed
  through a second ingress using the hostname `backend.<hostname>` with the same
  settings.
- `hpa` – enable CPU-based autoscaling for both deployments.

When `firebase.enabled` is true you must create the secret before installing the chart:

```bash
kubectl create secret generic firebase-config \
  --from-file=service-account.json=</path/to/serviceAccount.json> \
  --from-file=firebase-config.json=</path/to/firebaseConfig.json>
```

Install the chart with:

```bash
helm install xslt charts/xslt-playground
```
