Deploy MinIO on Docker Compose

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.
  • Docker installed on your machine. Download the relevant installer from here.
  • Create directories in your Linux machine
$ sudo mkdir /mnt/disk1 ... /mnt/disk8
  • Go to the data folder you wanted to save files
$ sudo fallocate -l 50G vhd1.img
$ sudo mkfs.xfs vhd1.img
$ sudo mount -o loop vhd1.img /mnt/disk1

Rum above commands one by one until you completed the disk8

  • Install local perist Plugin for docker
$ sudo curl -fsSL https://raw.githubusercontent.com/CWSpear/local-persist/master/scripts/install.sh | sudo bash

2. Run Distributed MinIO on Docker Compose

To deploy Distributed MinIO on Docker Compose, please download docker-compose.yaml and nginx.conf 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

docker-compose pull
docker-compose up

Windows

docker-compose.exe pull
docker-compose.exe up

Distributed instances are now accessible on the host at ports 9000, proceed to access the Web browser at http://127.0.0.1:9000/. Here 4 MinIO server instances are reverse proxied through Nginx load balancing.

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.

  • 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.
    • Add a new MinIO server instance to the upstream directive in the Nginx configuration file.
