1. ENCRYPTION_KEY handling:
- ENCRYPTION_KEY encrypts stored secrets (API keys, MFA, SMTP, OIDC) at rest.
- By default, the chart creates a Kubernetes Secret from `secretEnv.ENCRYPTION_KEY` in values.yaml.
- To generate a random key at install (preserved across upgrades), set `generateEncryptionKey: true`.
- To use an existing Kubernetes secret, set `existingSecret` to the secret name. The chart then
renders no Secret of its own and reads every secret env var from that secret: `ENCRYPTION_KEY`
(renamable via `existingSecretKey`), plus `ADMIN_EMAIL`, `ADMIN_PASSWORD`, `OIDC_CLIENT_SECRET`,
`UNSPLASH_ACCESS_KEY`, `PLACES_API_KEY`, `AMAP_API_KEY`, `AMAP_API_SECRET` and
`VAPID_PRIVATE_KEY`. Missing keys are simply left unset, so only provide the ones you use.
- If left empty, the server resolves the key automatically: existing installs fall back to
data/.jwt_secret (encrypted data stays readable with no manual action); fresh installs
auto-generate a key persisted to the data PVC.
2. JWT_SECRET is managed entirely by the server:
- Auto-generated on first start and persisted to the data PVC (data/.jwt_secret).
- Rotate it via the admin panel (Settings → Danger Zone → Rotate JWT Secret).
- No Helm configuration needed or supported.
3. Example usage:
- Set an explicit encryption key: `--set secretEnv.ENCRYPTION_KEY=your_enc_key`
- Generate a random key at install: `--set generateEncryptionKey=true`
- Use an existing secret: `--set existingSecret=my-k8s-secret`
- Use a custom key name in the existing secret: `--set existingSecret=my-k8s-secret --set existingSecretKey=MY_ENC_KEY`
4. Only one method should be used at a time. If both `generateEncryptionKey` and `existingSecret` are
set, `existingSecret` takes precedence. Ensure the referenced secret and key exist in the namespace.
5. Persistence:
- To bind your own PVCs, set `persistence.data.existingClaim` and/or `persistence.uploads.existingClaim`.
The other values for that volume (size, storageClassName, annotations) are then ignored.
- With `persistence.enabled=false` the volumes use an emptyDir — storage is ephemeral and is lost
when the pod restarts. Use only for testing.
