## MinIO Docker Tips

### MinIO Custom Access and Secret Keys

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly as environment variables. MinIO server also allows regular strings as access and secret keys.

#### GNU/Linux and macOS (custom access and secret keys)

The Prometheus endpoint in MinIO requires authentication by default. Prometheus supports a bearer token approach to authenticate prometheus scrape requests, override the default Prometheus config with the one generated using mc. To generate a Prometheus config for an alias, use [mc](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) as follows `mc admin prometheus generate <alias> [METRIC-TYPE]`....
