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.
