With Compose, you use a Compose file to configure MinIO services. Then, using a single command, you can create and launch all the Distributed MinIO instances from your configuration. Distributed MinIO instances will be deployed in multiple containers on the same host. This is a great way to set up development, testing, and staging environments, based on Distributed MinIO.

#### 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
