#### MINIO_DOMAIN

This is the top level domain name used for the federated setup. This domain name should ideally resolve to a load-balancer
running in front of all the federated MinIO instances. The domain name is used to create sub domain entries to etcd. For
example, if the domain is set to `domain.com`, the buckets `bucket1`, `bucket2` will be accessible as `bucket1.domain.com`
and `bucket2.domain.com`.
