### Secure Metrics Endpoint
Metrics endpoint `/metrics` can be secured by using `Bearer` token authentication.
**Note:** Providing non-empty `TOKEN` value will also require authentication for `ServiceMonitor`.
```yaml
gitea:
metrics:
enabled: true
serviceMonitor:
enabled: true
config:
metrics:
TOKEN: "secure-token"
```
## Pod annotations
Annotations can be added to the Gitea pod.
