Distributed Cluster Setup

# 4-node distributed cluster
minio server http://node{1...4}/data{1...4} \
  --console-address ":9001"

Getting Started

1. Deploy MinIO using Docker, Kubernetes, or bare metal
2. Access the console at http://localhost:9001
3. Create buckets for organizing your data
4. Configure access policies and users
5. Integrate applications using S3 SDKs
6. Set up monitoring and alerts

Client Integration

Python (boto3)

import boto3
from botocore.client import Config

# Configure MinIO client
s3 = boto3.client('s3',
    endpoint_url='http://localhost:9000',
    aws_access_key_id='minioadmin',
    aws_secret_access_key='minioadmin123',
    config=Config(signature_version='s3v4')
)

# Upload file
s3.upload_file('/path/to/file.txt', 'mybucket', 'file.txt')

JavaScript/Node.js

const AWS = require('aws-sdk');

// Configure MinIO client
const s3 = new AWS.S3({
    endpoint: 'http://localhost:9000',
    accessKeyId: 'minioadmin',
    secretAccessKey: 'minioadmin123',
    s3ForcePathStyle: true,
    signatureVersion: 'v4'
});

// Create bucket
s3.createBucket({Bucket: 'mybucket'}, (err, data) => {
    console.log(err || data);
});

Advanced Configuration

🔐 Security & Access Control

# Create service account
mc admin user add myminio newuser newuser123

# Create policy
mc admin policy add myminio readwrite policy.json

# Assign policy to user
mc admin policy set myminio readwrite user=newuser
