# Internal ENV Reference (operators)

End operators should use `erebrus status`, not this document.

## File locations

| Path                | Used by                                      |
| ------------------- | -------------------------------------------- |
| `/opt/erebrus/.env` | Docker install (`docker compose --env-file`) |

## Required bootstrap

| Variable           | Purpose                                              |
| ------------------ | ---------------------------------------------------- |
| `MNEMONIC`         | Node identity (12-word phrase)                       |
| `EREBRUS_ACCESS`   | `private` or `public` (gateway directory visibility) |
| `WG_ENDPOINT_HOST` | Public IP address clients dial                       |

## Release-only

| Variable         | Purpose             |
| ---------------- | ------------------- |
| `NODE_API_TOKEN` | Bearer for peer API |

## Optional Drop

| Variable             | Purpose                                           |
| -------------------- | ------------------------------------------------- |
| `DROP_ENABLED`       | Run the Docker-only Kubo sidecar integration      |
| `DROP_STORAGE_MAX`   | Kubo repository storage limit, default `10GB`     |
| `DROP_SWARM_PORT`    | Published Kubo TCP/UDP swarm port, default `4001` |
| `DROP_WEBUI_ENABLED` | Enable the exact-purpose private WebUI proxy      |

Kubo RPC (`5001`) and the raw Kubo gateway (`8080`) are never host-published. Files are accessed only through the authenticated Erebrus API.
