How to Self-Host MinIO S3-Compatible Object Storage

What Is MinIO?

MinIO is a high-performance, S3-compatible object storage server. It is designed for large-scale data infrastructure and works as a drop-in replacement for S3 in any application. MinIO is ideal for storing backups, media files, logs, and application data on your own Breeze.

Prerequisites

• A Breeze with at least 2 GB RAM running Ubuntu 22.04+
• Docker and Docker Compose installed
• Sufficient disk space for your storage needs

Docker Compose Setup

mkdir -p ~/minio && cd ~/minio

version: "3.8"
services:
  minio:
    image: minio/minio:latest
    container_name: minio
    restart: unless-stopped
    command: server /data --console-address ":9001"
    ports:
      - "9000:9000"
      - "9001:9001"
    volumes:
      - minio_data:/data
    environment:
      - MINIO_ROOT_USER=minioadmin
      - MINIO_ROOT_PASSWORD=ChangeThisPassword

volumes:
  minio_data:

Launch and Access

docker compose up -d

The API endpoint is available at port 9000 and the web console at port 9001. Log in to the console at http://your-breeze-ip:9001 using the root credentials.

Basic Usage

Install the MinIO client to interact from the command line:

mc alias set mybreeze http://your-breeze-ip:9000 minioadmin ChangeThisPassword
mc mb mybreeze/my-bucket
mc cp myfile.tar.gz mybreeze/my-bucket/

Integration Tips

• Use MinIO as an S3 backend for backup tools like Restic or Duplicati
• Configure application media uploads to write directly to MinIO buckets
• Set up bucket lifecycle policies for automatic object expiration
• Enable versioning on critical buckets for data protection
