Minio Java Library for Amazon S3 Compatible Cloud Storage

The Minio Java Client SDK provides simple APIs to access any Amazon S3 compatible object storage server.

This quickstart guide will show you how to install the client SDK and execute an example java program. For a complete list of APIs and examples, please take a look at the Java Client API Reference documentation.

This document assumes that you have one of the following Java Environments setup in place.

OracleJDK 7.0 or OracleJDK 8.0
OpenJDK7.0 or OpenJDK8.0

Download from maven

<dependency>
        <groupId>io.minio</groupId>
        <artifactId>minio</artifactId>

Download from JAR

You can download the latest JAR directly from maven.

Quick Start Example - File Uploader

This example program connects to an object storage server, makes a bucket on the server and then uploads a file to the bucket.

You need three items in order to connect to an object storage server.

MinioClient minioClient = new MinioClient("https://play.minio.io:9000", "Q3AM3UQ867SPQQA43P2F", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG");

Params	Description
Endpoint	URL to object storage service.
Access Key	Access key is like user ID that uniquely identifies your account.
Secret Key	Secret key is the password to your account.

We will use the Minio server running at https://play.minio.io:9000 in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.

require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
