### MinIO Custom Access and Secret Keys using Docker secrets

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as [Docker secrets](https://docs.docker.com/engine/swarm/secrets/). MinIO server also allows regular strings as access and secret keys.

```

// empty Write call that was interpreted as an EOF.
