+# Deploy Minio on Docker Compose [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io) [![Go Report Card](https://goreportcard.com/badge/minio/minio)](https://goreportcard.com/report/minio/minio) [![Docker Pulls](https://img.shields.io/docker/pulls/minio/minio.svg?maxAge=604800)](https://hub.docker.com/r/minio/minio/) [![codecov](https://codecov.io/gh/minio/minio/branch/master/graph/badge.svg)](https://codecov.io/gh/minio/minio)
+
+Docker Compose allows defining and running single host, multi-container Docker applications.
+
+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. 
+
+## 1. Prerequisites
+
+* Familiarity with [Docker Compose](https://docs.docker.com/compose/overview/).
+* Docker installed on your machine. Download the relevant installer from [here](https://www.docker.com/community-edition#/download).
+
+## 2. Run Distributed Minio on Docker Compose
+
+To deploy Distributed Minio on Docker Compose, please download [docker-compose.yaml](https://github.com/minio/minio/blob/master/docs/orchestration/docker-compose/docker-compose.yaml?raw=true) to your current working directory. Note that Docker Compose pulls the Minio Docker image, so there is no need to explicitly download Minio binary. Then run one of the below commands
+
+### GNU/Linux and macOS
+
+```sh
+docker-compose pull
+docker-compose up
+```
+
+### Windows
+
+```sh
+docker-compose.exe pull
+docker-compose.exe up
+```
+
+Each instance is now accessible on the host at ports 9001 through 9004, proceed to access the Web browser at http://127.0.0.1:9001/
+
+### Notes
+
+* By default the Docker Compose file uses the Docker image for latest Minio server release. You can change the image tag to pull a specific [Minio Docker image](https://hub.docker.com/r/minio/minio/).
+
+* There are 4 minio distributed instances created by default. You can add more Minio services (up to total 16) to your Minio Compose deployment. To add a service
+  * Replicate a service definition and change the name of the new service appropriately.
+  * Update the command section in each service.
+  * Update the port number to exposed for the new service. Also, make sure the port assigned for the new service is not already being used on the host.
+
+  Read more about distributed Minio [here](https://docs.minio.io/docs/distributed-minio-quickstart-guide).
+
+* Minio services in the Docker compose file expose ports 9001 to 9004. This allows multiple services to run on a host.
