## 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)

```sh
docker run \
  -p 9000:9000 \
  -p 9001:9001 \
  --name minio1 \

      // move last entry to deleted spot
      Object key = keys[srcIndex];
      keys[dstIndex] = key;
      values[dstIndex] = values[srcIndex];
      keys[srcIndex] = null;
      values[srcIndex] = null;
